RESUMO

Background: The present study aimed to investigate the effects of post-activation performance enhancement (PAPE) after three warm-up protocols on back squat performance in trained men. Methods: Fourteen resistance-trained men performed conditioning activity (CA) with high-load (HL-CA), low-load (LL-CA), or usual specific warm-up as a control (CON). HL-CA consisted of one set of three repetitions with 90% of one repetition maximum (RM); LL-CA consisted of one set of six repetitions with 45% of 1 RM performed at maximal velocity; CON involved eight repetitions with 45% of 1 RM at controlled velocity. The participant's performance was measured using the total number of repetitions and volume load (reps × load × sets). Results: There were no significant differences between warm-up for the total number of repetitions (p = 0.17) or total volume load (p = 0.15). There was no difference between conditions for the number of repetitions (main condition effect; p = 0.17); however, participants achieved a significantly higher volume load after HL-PAPE than after CON for the first set (p = 0.04). Conclusion: High or low equated-load CA used as warm-up strategies did not potentiate subsequent performance enhancement in multiple-set back squat exercise performed until muscle failure in comparison with usual warm-up.

RESUMO

Resumen Objetivo: Analizar el efecto de una activación realizada a través de ejercicios de fuerza y pliometría ejecutados de forma bilateral o unilateral sobre el rendimiento en salto horizontal. Metodología: En el estudio participaron 15 futbolistas masculinos, altamente entrenados (edad, 24.7 ± 3.1 años; altura, 181.2 ± 4.7 cm; peso, 79.7 ± 3.4 kg) pertenecientes al mismo equipo, que competía en liga nacional. Su rutina de entrenamiento regular constaba de 4 sesiones y 1 partido competitivo por semana. Los participantes llevaron a cabo 1 protocolo control (CON) y 3 protocolos de activación, siguiendo un diseño contrabalanceado, basados en ejercicios específicos de fútbol (SIN), ejercicios de fuerza y pliometría ejecutados de forma bilateral (BIL) y unilateral (UNI). Después de cada protocolo los jugadores realizaron la prueba de salto horizontal (HZB). Resultados: Los resultados de la prueba ANOVA de medidas repetidas mostraron efectos positivos significativos sobre el HZB de los protocolos SIN (p<0.01; dif = 2.95(2.00)%), BIL (p<0.01; dif = 3.22(2.61) %); y UNI (p<0.01; dif = 6.80(3.40) %) con respecto a CON. Además, HZB fue, significativamente, mayor después del protocolo UNI que del SIN (p<0.01; dif = 3.74(2.62) %) y BIL (p<0.01; dif = 3.47(1.94) %). El análisis de la respuesta individual reflejó efectos positivos en HZB de los protocolos SIN, BIL y UNI respecto al CON, mientras que el 89 % de los jugadores tuvieron mejor rendimiento en HZB después de UNI que de BIL. Conclusiones: Una activación que incorpora estímulos de fuerza y pliometría ejecutados, de forma unilateral, tiene un efecto positivo mayor sobre la capacidad de salto horizontal, que una activación que involucra ejercicios generales, específicos de fútbol y de ejecución bilateral.


Abstract Objective: To analyze the effect of activation through bilateral or unilateral strength and plyometric exercises on horizontal jump performance. Methodology: The study involved 15 highly trained male soccer players (age, 24.7 ± 3.1 years; height, 181.2 ± 4.7 cm; weight, 79.7 ± 3.4 kg) from the same team competing in the national league. Their regular training routine consisted of 4 sessions and 1 competitive match per week. Participants performed 1 control protocol (CON) and 3 activation protocols following a counterbalanced design based on specific soccer exercises (SIN), bilateral (BIL), and unilateral (UNI) strength and plyometric exercises. After each protocol, players underwent the horizontal jump test (HZB). Results: The repeated measures ANOVA revealed significant positive effects on HZB for the SIN (p<0.01; diff = 2.95(2.00) %), BIL (p<0.01; diff = 3.22(2.61) %), and UNI (p<0.01; diff = 6.80(3.40) %) protocols compared to CON. Furthermore, HZB was significantly higher after the UNI protocol than after SIN (p<0.01; diff = 3.74(2.62) %) and BIL (p<0.01; diff = 3.47(1.94) %). Individual response analysis reflected positive effects on HZB for SIN, BIL, and UNI compared to CON, while 89 % of players showed better HZB performance after UNI than after BIL. Conclusions: Activation incorporating unilateral strength and plyometric stimuli has a greater positive effect on horizontal jump capacity than activation involving general, soccer-specific, and bilateral exercises.

RESUMO

The objectives of this study were to evaluate the acute effects of the sequence order of drop jumps (DJ) and dynamic stretching (DS) on sprinting performances in competitive athletes and to investigate the relationships between post-activation performance enhancement (PAPE) in sprint performance and lower limb power. Thirteen male jumpers and sprinters participated in this study (19 ± 2 years; 177 ± 7 cm; 71.7 ± 5.6 kg). Through a randomized crossover design, the athletes were exposed to three different conditions after a standardized warm-up: DS+DJ, DJ+DS, and control. Sprinting performance over 40 m was analysed with consideration of initial (0 to 20 m) and final acceleration (20 to 40 m) phases. The effect of intervention was examined by two-way repeated-measures of ANOVA. Pearson's correlation test was used to determine the association between PAPE during sprinting and jump performance. There was no effect of any factor on 40-m sprint performance. Meanwhile, the performance at 20-40 m was higher after the DS+DJ condition when compared to baseline (8.79 ± 0.43 vs. 8.91 ± 0.35 m/s; p = 0.015). However, the initial acceleration was worsened in the DJ+DS condition when compared to baseline (6.26 ± 0.25 vs. 6.22 ± 0.26 m/s; p = 0.002). There was a negative correlation between CMJ height and the improvement in final acceleration (r = -0.741; p = 0.004). The use of DS prior to DJ is an effective strategy to improve performance in the final acceleration phase (20-40 m). The athletes with lower levels of lower limb power benefited the most from this PAPE strategy.

RESUMO

In athletics, achieving peak performance during competitions is crucial. Warm-up strategies play a crucial role in optimizing the strength-speed performance of sprinters in athletics, especially tailored to the physiological demands of speed events. The need to balance flexibility, prevent injuries, and enhance power output makes the selection of an effective warm-up protocol essential. This narrative review examines different warm-up methods used by athletes and their effects on strength-speed in sprinters in athletics. The main findings indicate that Foam Rolling (FR), Isometric Exercises and Pre-Competitive Massages have no significant effects on sprint performance. Static stretching and prolonged Pre-Competitive Massages have negative impacts on strength and power. The Vibration Platform enhances step length, step rate and running velocity, jump height and total number of jumps performed in a 30-s period in non-experienced sprinters. Eccentric Exercise increases vertical force, Post-Activation Potentiation (PAP) demonstrates a reduction in 100-meter time and short-term improvement in vertical and horizontal jumps. Blood Flow Restriction (BFR) significantly improving jump height and flight time. Various warm-up methods have been identified, some focusing on flexibility, others potentially detrimental, and some enhancing strength and power. Implementing effective warm-ups, particularly those promoting strength and power, poses a challenge for coaches seeking reliable alternatives to boost performance.

RESUMO

BACKGROUND: The scientific literature questions the impact of stretching exercises performed immediately before muscle strengthening exercises on different components of musculoskeletal physical fitness. Pilates is a physical exercise modality that typically uses stretching exercises preceding muscle-strengthening exercises. However, no studies have investigated the effects of stretching in a Pilates program on components of musculoskeletal fitness. The aim of the present study was to verify the effects of stretching in a Pilates exercise program on flexibility, strength, vertical jump height and muscular endurance. METHODS: Thirty-two sedentary young women were randomized into two groups: traditional Pilates (TP), who performed flexibility and muscle strengthening exercises (n = 16), and nontraditional Pilates (NTP), who only performed muscle-strengthening exercises (n = 16). Sessions took place 3 times a week for 8 weeks. The following tests were performed pre- and postintervention: 10-RM knee extensors, vertical jump, handgrip, 1-min sit-ups, Sorensen and sit-and-reach. The occurrence of adverse events was recorded throughout the intervention and compared between groups using odds ratio (OR). To compare the results of motor tests between groups, ANCOVA or Mann‒Whitney U test was used for parametric and nonparametric data, respectively. The data were analyzed by intention-to-treat. RESULTS: After intervention, the TP was superior to NTP for the sit-and-reach test, with a large effect size (d = 0.87; p = 0.035), with no differences between groups for the other tests. Intragroup comparisons showed significant differences (p < 0.05) for TP and NTP for improvement in 10-RM knee extensors and vertical jump measurements, while only TP showed significant intragroup improvement (p < 0.05) for the sit-and-reach test. A greater chance of experiencing pain or other discomfort as a result of exercise was shown by NTP (OR = 4.20, CI95% 0.69 to 25.26). CONCLUSION: Our findings demonstrated that stretching exercises performed at the beginning of sessions in a Pilates program did not impair or enhance the development of strength, vertical jump height and muscular endurance in young women. However, only the Pilates program with stretching improved flexibility and reduced the chances of adverse events such as musculoskeletal pain and other discomfort resulting from the exercise protocol. CLINICALTRIALS: GOV: NCT05538520, prospectively registered on September 16, 2022.

RESUMO

Our aim was to investigate if using a warm-up routine that included parachute-resisted sprints with large hand-paddles improves 50 m freestyle performance in trained collegiate swimmers. Twelve swimmers (23.9 ± 2.2 years, 179 ± 7 cm, 77.1 ± 10.6 kg) participated in the study and completed two 50-m freestyle races, each preceded by a different warm-up routine, either control (CON) or experimental (EXP). The warm-up routines consisted of 500 m of swimming at self-selected speed, followed by four 10 s sprints with 1 min rest intervals. During EXP, sprints were performed using large hand-paddles and a swimming parachute, while during CON, sprints were performed freely. Performance and technique were assessed during the 50 m freestyle races. We found no significant differences in 25- and 50 m performance times (CON: 12.6 ± 0.8 vs. EXP: 12.5 ± 0.8 s, ES = 0.125; and CON: 26.8 ± 1.6 vs. EXP: 26.7 ± 1.7 s, ES = 0.06, respectively) between the two conditions. Mean stroke length (CON: 2.04 ± 0.21 vs. EXP: 2.02 ± 0.22 m·cycle-1, ES = 0.09), stroke frequency (CON: 55.4 ± 5.3 vs. EXP: 56.3 ± 5.2 cycles s-1, ES = 0.17), and propulsive time (CON: 0.62 ± 0.07 vs. EXP: 0.61 ± 0.06 s, ES = 0.15) were also not different between conditions. It is possible that the CON warm-up routine induced the priming effects that lead to PAPE, or that the EXP warm-up routine primed the athletes further but also induced greater fatigue, resulting in no significant effects on swimming performance. Our findings suggest that parachute-resisted sprints with hand-paddles during warm-up do not enhance 50 m freestyle swimming performance in trained collegiate swimmers. Coaches and practitioners should consider exploring different warm-up protocols to identify what works best for their athletes.

RESUMO

Studies on postactivation performance enhancement (PAPE) have used different exercises as a conditioning activity to investigate potentiation, but exclusively in upper limbs (UL) or lower (LL) limbs, or contralateral potentiation. A single exercise capable of inducing PAPE in both UL and LL is currently unknown. The present study explored the effect of the clean and jerk (C&J) as a conditioning activity for simultaneously producing PAPE interlimbs at the fourth, seventh, and 12th minutes postintervention. Twelve male weightlifters with 1-repetition maximum (1RM) in the C&J equivalent to ≥1.15 × body mass were randomly submitted to 2 experimental conditions (C&J and control [CON]). The C&J condition consisted of general warm-up (running on a treadmill and self-selected preparatory exercises) and 4 sets of 3 repetitions of C&J with 2 minutes between them (30%1RM, 50%1RM, 65%1RM, and 80%1RM) followed by a countermovement jump and a bench-press throw on a Smith machine after 4, 7, and 12 minutes, to measure the magnitude of PAPE in UL and LL. No previous exercise preceded countermovement-jump and bench-press-throw tests in the CON besides general warm-up. The main finding was that, regardless of time, the C&J resulted in greater height on countermovement jump and Smith machine bench-press throw when compared with the CON, presenting a similar effect size between UL and LL (34.6 [3.9] vs 33.4 [4.1] cm [+3.66%]; P = .038; effect size = 0.30 and 30.3 [4.7] vs 29.0 [5.1] cm [+4.44%]; P = .039; effect size = 0.26), respectively. Thus, C&J can be useful to produce PAPE simultaneously among members.

RESUMO

Warm-up protocols with high intensities before continuous running provide potential benefits for middle-distance runners. Nevertheless, the effect of high-intensity warm-ups on long-distance runners remains unclear. The purpose of this study was to verify the effect of a high-intensity warm-up protocol on 5000 m performance in trained runners. Thirteen male runners (34 ± 10 years, 62 ± 6 kg, 62.7 ± 5.5 ml/kg/min) performed two 5000 m time trials, preceded by two different warm-ups. One high-intensity warm up (HIWU: 1x 500 m (70% of the running intensity) + 3x 250 m (100% of the running intensity) and one low-intensity warm up (LIWU: 1x 500 m (70% of the running intensity) + 3x 250 m (70% of the running intensity)), where the running intensities were calculated using the results obtained in the Cooper test. Physiological and metabolic responses, and endurance running performance parameters, were evaluated by the Counter Movement Jump (CMJ), running rating of perceived exertion (RPE), blood lactate concentration (BLa), and performance running. Total time for the 5000 m was lower using HIWU when compared to LIWU (1141.4 ± 110.4 s vs. 1147.8 ± 111.0 s; p = 0.03; Hedges' g = 0.66). The HIWU warm-up led to an improvement in pacing strategy during the time trial. After warm-up protocols, the performance on the CMJ was improved only when applying HIWU (p = 0.008). Post warm-up BLa was significantly higher for HIWU vs. LIWU (3.5 ± 1.0 mmol·L-1 vs. 2.3 ± 1.0 mmol·L-1; p = 0.02), with similar behavior for the RPE (p = 0.002), internal load of the session (p = 0.03). The study showed that a high-intensity warm-up protocol can improve performance in the 5000 m in trained endurance runners.

RESUMO

PURPOSE: This study investigated the effects of both an active warm-up and the time-of-day variation on repeated-sprint performance. A second objective was to compare the post-exercise recovery between the experimental conditions. METHODS: Eleven male participants performed ten maximal cycling sprints (6 s each, with a 30-s interval between them) in the morning and late afternoon, either after a warm-up or control condition. The warm-up consisted of cycling for 10 min at 50% of the peak aerobic power. RESULTS: Rest measurements of rectal, muscle, and skin temperatures were higher in the afternoon compared to the morning (p < 0.05), with no significant differences in heart rate (p = 0.079) and blood lactate concentration (p = 0.300). Warm-up increased muscle temperature, heart rate, and lactate, and reduced skin temperature (all p < 0.001), though no significant differences were observed for rectal temperature (p = 0.410). The number of revolutions (p = 0.034, ηp2 = 0.375), peak (p = 0.034, ηp2 = 0.375), and mean (p = 0.037, ηp2 = 0.365) power of the first sprint (not the average of ten sprints) were higher in the afternoon compared to the morning, regardless of warm-up. However, beneficial performance effects of warming up were evident for the first (p < 0.001) and the average of ten sprints (p < 0.05), regardless of time of day. More remarkable changes during the 60-min post-exercise were observed for rectal temperature (p = 0.005) and heart rate (p = 0.010) in the afternoon than in the morning. CONCLUSION: Warming-up and time-of-day effects in enhancing muscular power are independent. Although warm-up ensured further beneficial effects on performance than the time-of-day variation, a faster post-exercise recovery was observed in the late afternoon.

RESUMO

ABSTRACT Introduction: Competitive gymnastics training is extremely debated in the Chinese scientific community. It is only when coaches choose proper physical training methods, they can fundamentally improve gymnasts' physical fitness. Objective: Analyze the effect of warm-up exercises on gymnasts' physical fitness. At the same time, this paper analyzes the factors that influence the indicators of gymnasts' physical fitness. Methods: This paper selects several gymnasts as research objects. The gymnasts perform physical training with interval training warm-up for two months. Data of gymnasts' physical constitution and the indicators related to their function are tracked and tested. Morphological indicators include height, circumference and body composition; functional indicators include multiple physiological and biochemical indicators (blood and urine analysis). Results: Gymnasts increased urea and creatine kinase concentrations after warm-up physical training. However, there was no statistical difference (P>0.05). The primary functional status of the athletes was stable. The results showed a normal resting heart rate and a reduction of blood pressure in the elite athletes. Conclusion: Gymnasts using interval training can maintain high intensity levels for prolonged periods. The indicators of physical fitness were above average. However, players' fitness to complete the movement set needs to be improved. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

RESUMO

To verify the acute effect of drop jumps (DJ) on two repeated sprint ability tests (RSA), interspersed with a rest period simulating a basketball game break. Twelve first division basketball players (age: 24.8 ± 6.9 years; body mass: 97.0 ± 9.2 kg; height: 2.0 ± 0.1 m) performed, in a randomized crossover design, two RSA tests separated by 5 min after DJ or control conditions. The DJ condition comprised 5 DJs performed 4 min prior to the first RSA test, whereas 3 DJ were completed 30 s prior to a second RSA test. Surface electromyography was recorded from the lower body for root mean square (RMS) analyses during sprinting. Three countermovement jump (CMJ) tests were performed after warming up and immediately after the second RSA test. DJ improved RSA performance with a faster best time in the first RSA test (p = 0.035), and a shorter total time and mean time (p = 0.030) for the second RSA test. No significant differences were found in RMS between protocols. CMJdecreased in both conditions after the RSA tests (p < 0.05). This study revealed a post-DJ RSA potentiation in professional male basketball players. This simple and effective approach could be implemented at the end of the warm-up and before the end of game breaks to improve player preparedness to compete.

RESUMO

RESUMEN La lesión deportiva trae consigo deterioro de la salud física y mental del atleta, gastos económicos y perdida de los entrenamientos y competencias, que juegan un papel fundamental en el éxito deportivo. Los programas de prevención de lesiones se vienen implementando como una herramienta eficaz en el cuidado de la salud y la optimización del rendimiento deportivo. Objetivo: Comparar el comportamiento de la lesión en atletas posterior a un programa de calentamiento neuromuscular de prevención de lesiones. Material y método: Se realizó un estudio cuasiexperimental, de tipo comparativo, con 80 deportistas, en los deportes de actividades subacuáticas, bádminton, judo, halterofilia, patinaje, triatlón y taekwondo del departamento del Cauca, aplicando un programa preventivo de calentamiento neuromuscular estructurado en el cual se comparaba en la misma muestra de sujetos un antes y un después; para la vigilancia de la lesión se utilizó una ficha de seguimiento del comportamiento de la lesión. Resultados: Antes de la aplicación del programa de prevención de lesiones, el 55 % de los deportistas presentaron lesión, siendo de mayor frecuencia las tendinopatía y los esguinces, y la rodilla fue la articulación más afectada, mientras que luego de la aplicación del programa de prevención aparecieron lesiones en el 34 % (36/80) de los deportistas; clínicamente se encontró que los deportes de combate, de tiempo y marca presentaron una reducción de lesión del 25,8 y 2,8 %, respectivamente posintervención, en cambio, los deportes de pelotas y raqueta aumentaron incidencia de lesión en un 20 %: la comparación antes y después de la aplicación del programa para las variables tipo de lesión, práctica deportiva, estructura y zona de lesión no presentaron significancia estadística entre sí. Conclusión: El programa de calentamiento neuromuscular para prevención de lesiones presentó diferencias clínicas en la incidencia de lesión posterior a la intervención, aunque estas no fueron estadísticamente significativas.


ABSTRACT Sports injuries carry a deterioration of athletes physical and mental health, economic expenses, and loss of training and competitions, playing a fundamental role in sports success. Injury prevention programs are being implemented as an effective tool in health care and optimization of sports performance. Objective: To compare the injury behavior in athletes after a neuromuscular warm-up program for injury prevention. Material and methods: 80 athletes in the sports of underwater activities, badminton, judo, weightlifting, skating, triathlon, and taekwondo from the Cauca Department, a quasi-experimental comparative study was carried out, applying a before and after preventive program of structured neuromuscular warming for lesions surveillance. A form to track the behavior of the injury was used. Results: Before the application of the injury prevention program, 55% of the athletes presented injury, tendinophaty, and sprains being more frequently, where the knee was the most affected joint, while, after the application of the prevention program, lesions appeared in 34% (36/80) of the athletes; clinically, it was observed that combat, time, and brand sports presented a reduction of injury in 25.8% and 2.8%, respectively, post intervention. On the other hand, balls and racket sports increased the incidence of injury in 20%; the comparison of the results before and after applying the program for the variables type of injury, sports practice, structure, and area of injury did not show statistical significance among themselves. Conclusion: The neuromuscular warming program for injury prevention presented clinical differences in the incidence of injury after the intervention, although these were not statistically significant.

RESUMO

This study aimed to compare the effects of the post-activation performance enhancement (PAPE) of two different types of warm-ups, unilateral and bilateral, on the performance in vertical jumping and agility of healthy subjects with strength training experience. In the study, 17 subjects (12 men and 5 women) performed two different PAPE protocols: unilateral squat (UT) and bilateral squat (BT). The height of the subjects' countermovement jump (CMJ) and the subjects' time to perform the T-agility test (TAT) were measured before and after executing the PAPE warm-up. The squats were performed at a velocity of 0.59 m·s-1 with three sets of three repetitions, with a 3-min rest between sets and a 5-min rest after both uni- and bilateral PAPE warm-ups before taking the tests again. For statistical analysis, we applied ANOVA and calculated the effect size. The results showed that the PAPE for each case decreased the CMJ height but generated significant improvements in the total time taken for the T-agility test (p < 0.01); however, in both cases, the effect sizes were trivial. In conclusion, it is possible to observe that the PAPE, performed both unilaterally and bilaterally, negatively affects the performance in the vertical jump, showing moderate effect sizes. However, both PAPE protocols show performance benefits in agility tests, with a large effect size for the unilateral protocol and moderate for the bilateral protocol.

RESUMO

ABSTRACT Introduction Among the many cases of sports injuries, the incidence of musculoskeletal injuries remains high. After a musculoskeletal injury occurs, athletes often need to suspend training and undergo rehabilitation. A suitable sport mode requires athletes to have sufficient joint range of motion, core stability, and balance ability in different positions to complete various complex movements in training and competition. Objective The paper analyzes the impact of warm-up exercises before the test on the test results of functional sports biological image data screening ( FMS TM ) and provides references for unifying test conditions, checking the reliability of FMS TM repeated tests, and discussing the comparability of the research results. Methods The paper used the same password and process to test 12 young male volleyball professional athletes without warm-up and warm-up. The two-dimensional motion analysis system Dartfish Pursuit 8.0 was used to analyze the video data recorded by the two cameras simultaneously. Results In the two tests before and after, the hurdle step score (1.75±0.62 vs. 2.42±0.52) and the total score (13.50±2.20 vs. 16.42±2.15) were significantly higher than those without the warm-up test (P<0.01). Besides, in squats (1.58±0.67 vs. 1.92±0.67), straight lunges (2.00±0.43 vs. 2.50±0.52), active straight leg lifts (1.50±0.67 vs. 2.00±0.60), rotation stability (1.42) ±0.52 vs. 1.92±0.29) showed a significant increase in the score (P<0.05). Conclusions Warm-up exercises before the test can improve the test results. This abnormal movement pattern observed only by visual inspection may not truly reflect the "dysfunction" of the movement. In the case of ignoring the pre-test warm-up factors, feedback on sports performance and formulating training strategies, this conclusion of predicting injury risk and evaluating training effects may have specific limitations in its reference value. Level of evidence II; Therapeutic studies - investigation of treatment results.


RESUMO Introdução Dentre os diversos casos de lesões esportivas, a incidência de lesões musculoesqueléticas permanece elevada. Após a ocorrência de uma lesão musculoesquelética, os atletas geralmente precisam suspender o treinamento e se submeter à reabilitação. Um modo de esporte adequado requer que os atletas tenham amplitude de movimento articular suficiente, estabilidade central e capacidade de equilíbrio em diferentes posições para completar vários movimentos complexos em treinamento e competição. Objetivo o artigo analisa o impacto dos exercícios de aquecimento antes do teste sobre os resultados dos testes de triagem de dados de imagens biológicas esportivas funcionais (FMSTM) e fornece referências para unificar as condições de teste, verificar a confiabilidade de testes FMSTM repetidos e discutir a comparabilidade dos resultados da pesquisa . Métodos O artigo utilizou a mesma senha e processo para testar 12 jovens atletas profissionais do sexo masculino de voleibol sem aquecimento e com aquecimento. O sistema de análise de movimento bidimensional Dartfish Pursuit 8.0 foi usado para analisar os dados de vídeo gravados pelas duas câmeras simultaneamente. Resultados Nos dois testes antes e depois, a pontuação do hurdle step (1,75 ± 0,62 vs. 2,42 ± 0,52) e a pontuação total (13,50 ± 2,20 vs. 16,42 ± 2,15) foram significativamente maiores do que aqueles sem o teste de aquecimento ( P <0,01). Além disso, em agachamentos (1,58 ± 0,67 vs. 1,92 ± 0,67), estocadas retas (2,00 ± 0,43 vs. 2,50 ± 0,52), levantamentos ativos de perna reta (1,50 ± 0,67 vs. 2,00 ± 0,60), estabilidade de rotação (1,42) ± 0,52 vs. 1,92 ± 0,29) mostrou um aumento significativo na pontuação (P <0,05). Conclusão Os exercícios de aquecimento antes do teste podem melhorar os resultados do teste. Este padrão de movimento anormal observado apenas por inspeção visual pode não refletir verdadeiramente a "disfunção" do movimento. No caso de ignorar os fatores de aquecimento pré-teste, feedback sobre o desempenho esportivo e formulação de estratégias de treinamento, esta conclusão de prever o risco de lesões e avaliar os efeitos do treinamento pode ter limitações específicas em seu valor de referência. Nível de evidência II; Estudos terapêuticos - investigação dos resultados do tratamento.

RESUMO

Testicular vitrification is an alternative to preserve the genetic material of pre-pubertal animals. However, there are few studies on post-vitrification warming. Hence, the aim was to compare the influence of different warming temperatures on vitrified testicular fragments from pre-pubertal cats. The testicles were fragmented and divided into a control group (non-vitrified) and vitrified, using an association between dimethylsulphoxide and glycerol. The vitrified fragments were warmed at 50, 55 and 60°C/5 s. Morphological and morphometric evaluations were carried out using classical histology. Afterwards, the mitochondrial activity was evaluated using Rhodamine 123. The data were expressed in mean and standard error. The differences were considered significant when p < .05. In the histomorphological analysis, the testicular fragment presented seminiferous tubules with poorly developed germinal epithelium, compatible with pre-pubertal animals. The group warmed at 50°C presented similar to the control regarding the maintenance of the integrity of the tubules and cells, without stromal rupture and lamina propria alteration, as well as regarding the maintenance of the junctions between the cells. The group warmed at 55°C showed reduction of the cell junctions, and the one warmed at 60°C had increased detachment of the basement membrane (p < .05). The warming caused a reduction in the tubular diameter inversely proportional and progressive to the increase in temperature, with the highest diameter in the control group and the lowest in the 60°C group. The control group showed a lower incidence of Rhodamine 123, followed in ascending order of the warmings at 55 and 60°C. The higher mitochondrial activity was obtained with 50°C, showing an increase of the metabolic cell function at this temperature. It was concluded that the testicular fragment of pre-pubertal cats presents a better preserved morphology, morphometry and viability when warmed at 50°C.

RESUMO

(1) Background: the present study aimed to evaluate the effect of different types of warm-ups on the strength and skin temperature of Paralympic powerlifting athletes. (2) Methods: the participants were 15 male Paralympic powerlifting athletes. The effects of three different types of warm-up (without warm-up (WW), traditional warm-up (TW), or stretching warm-up (SW)) were analyzed on static and dynamic strength tests as well as in the skin temperature, which was monitored by thermal imaging. (3) Results: no differences in the dynamic and static indicators of the force were shown in relation to the different types of warm-ups. No significant differences were found in relation to peak torque (p = 0.055, F = 4.560, η2p = 0.246 medium effect), and one-repetition maximum (p = 0.139, F = 3.191, η2p = 0.186, medium effect) between the different types of warm-ups. In the thermographic analysis, there was a significant difference only in the pectoral muscle clavicular portion between the TW (33.04 ± 0.71 °C) and the WW (32.51 ± 0.74 °C) (p = 0.038). The TW method also presented slightly higher values than the SW and WW in the pectoral muscles sternal portion and the deltoid anterior portion, but with p-value > 0.05. (4) Conclusions: the types of warm-ups studied do not seem to interfere with the performance of Paralympic Powerlifting athletes. However, the thermal images showed that traditional warm-up best meets the objectives expected for this preparation phase.

RESUMO

Abstract Aim: Several health professionals prescribe static stretching exercises (SS) as essential for those that practice physical exercises, for injury prevention and performance improvement, although there is still no consensus. There are few studies on the effects of SS use on warming up. Thus study aimed to compare the effects of the inclusion of SS in general warming up procedures on muscle strength in Brazilian army personnel. Methods: Thirty-two young military men were selected. They were subjected to anthropometric evaluation and performed knee extension and flexion in an isokinetic digital dynamometer, at a speed of 60°/s. Then, they were divided into two randomized and counterbalanced groups, Traditional Group (TG) and Experimental Group (EG). The TG performed the lower limbs warm-up protocol provided for military physical training (MPT) and immediately after, performed the isokinetic muscle strength test. The EG performed the same protocol, performing the SS in the hamstrings and quadriceps, before warming up. Results: An increase was found in the peak isokinetic torque in the knee extension of the EG (Pre: 209.80 ± 21.36 vs Post: 243.98 ± 30.35; p = 0.001) and flexion (Pre: 130.86 ± 18.63 vs Post: 142.41 ± 25.92; p = 0.006). In the TG, significant differences were found in the extension of the knee, but not in flexion (Pre: 209.14 ± 34.27 vs. Post: 239.38 ± 36.17; p = 0.001 and Pre: 129.23 ± 18.43 vs Post: 133.66 ± 13.20; p = 0.297, respectively). Conclusion: The inclusion of SS in general warming up did not harm and even improved muscle strength performance in knee extension and flexion in Brazilian Army military personnel.

RESUMO

RESUMO O objetivo deste estudo foi verificar o efeito da massagem ou pseudomassagem no desempenho do salto vertical. Quinze participantes foram submetidos aleatoriamente a três condições experimentais: massagem, pseudomassagem e repouso. A condição de massagem exigiu três saltos verticais unipodais seguidos de dois minutos de massagem manual nos músculos flexores plantares e, antes de executar outros três saltos, foi aplicada a Escala de Recuperação de Qualidade Total (TQR). As duas condições a seguir foram estruturadas com os mesmos procedimentos, no entanto, os participantes foram submetidos à pseudomassagem (simples-cego) ou a dois minutos de descanso. Os resultados não mostraram diferenças estatísticas na altura do salto entre as análises pré e pós, nem entre as condições experimentais (massagem 18,7 ± 4,1 vs. 18,2 ± 4,1; pseudomassagem 19,1 ± 4,0 vs. 18,3 ± 3,8; descanso 19,0 ± 4,0 vs. 18,7 ± 3,9 cm). Também não houve diferenças estatísticas no TQR entre as condições experimentais (massagem 16,2 ± 4,3; pseudomassagem 16,4 ± 3,9; descanso 15,9 ± 2,6 ua). Tanto a massagem quanto a pseudomassagem não afetaram o desempenho no salto vertical e na TQR.


ABSTRACT The aim of this study was to verify the effect of massage or pseudo massage on vertical jump performance. Fifteen participants were randomly subjected to three experimental conditions: massage, pseudo massage and rest. The massage condition required three unipodal vertical jumps followed by two minutes of manual massage on plantar flexor muscles and, before performing another three jumps, the Total Quality Recover Scale (TQR) was applied. The two following conditions were structured with the same procedures, although participants were submitted either at pseudo massage (single-blinded) or two minutes of rest. Results showed no statistical differences on jump height between pre and post analysis nor between experimental conditions (massage 18.7 ± 4.1 vs 18.2 ± 4.1; pseudo massage 19.1 ± 4.0 vs 8.3 ± 3.8; rest 19.0 ± 4.0 vs 18.7 ± 3.9 cm). There were also no statistical differences in the TQR results between experimental conditions (massage 16.2 ± 4.3; pseudo massage 16.4 ± 3.9; rest 15.9 ± 2.6 ua). Both massage and pseudo massage did not affect performance on vertical jump and TQR.

RESUMO

Ischemic preconditioning (IPC) has been used to increase performance in sports. The aim of this study was to compare the acute effects of IPC with different warm-up methods on the number of repetitions and total volume in resistance exercise (RE). Sixteen healthy men recreationally trained in RE participated in this study. After the anthropometric evaluation and familiarization, a one-repetition maximum (1RM) test and retest were performed in the bench press (BP) and in the leg press 45° (LP) exercise. After these tests, participants were randomly assigned to one of the five protocols: a) IPC; b) SHAM; c) a specific warm-up (SW); d) aerobic exercise (AE), and e) active stretching (AS) prior to performing 3 sets at 80% 1RM until concentric failure. The number of repetitions was higher following IPC compared to the SW following three sets both for the BP and LP. Similarly, the number of repetitions for IPC was higher in comparison to SHAM following three sets for the LP. The number of repetitions was higher following IPC compared to AE following 1st and 2nd sets for the LP and following the 2nd set for the BP. Finally, the number of repetitions was higher following IPC compared to AS following 1st and 2nd sets for the LP. The total volume was higher following IPC compared to SHAM, SW, AE, and AS for both the BP and LP. The IPC protocol increased the number of maximum repetitions and the total volume when compared to the other tested methods, thus indicating a better utilization during the pre-work warm-up. These results indicate positive associative responses to IPC with performance maintenance, which is of importance for both athletes and coaches.
