RESUMEN

Resumen Antecedentes: La participación de las mujeres en el fútbol se ha incrementado exponencialmente en los últimos años, por lo que integrar antecedentes basados en la evidencia en esta población, permite una mejor compresión y análisis del desempeño deportivo de atletas femeninas. Objetivo: Determinar el nivel de asociación entre los indicadores de composición corporal y el rendimiento en test 30-15 IFT en futbolistas mujeres de primera división. Métodos: Participaron 29 jugadoras profesionales de un equipo de primera división de Chile. Se evaluó el test 30-15, se analizó la velocidad final alcanzada (VIFT) y se estimó el consumo máximo de oxígeno (VO2máx). La composición corporal (CC) fue estimada a través de antropometría y se analizó la talla, masa corporal, índice de masa corporal (IMC), masa adiposa absoluta (MA) y relativa (PMA), masa muscular absoluta (MM) y relativa (PMM) y sumatoria de 6 pliegues (S6P). Para analizar el nivel de asociación, se utilizó el coeficiente de correlación de Pearson (r) con un alfa de 0.05. Resultados: Se encontraron correlaciones negativas débiles entre MA con VIFT (r = -0.384 y p = 0.04) y VO2máx (r = -0.375 y p = 0.45); correlaciones negativas moderadas entre S6P con VIFT (r = -0.476 y p = 0.009) y VO2máx (r=0.454 y p=0.013); correlaciones negativas moderadas entre IMC con VIFT (r = 0.401 y p = 0.031) y VO2máx (r = -0.379 y p = 0.043). No se hallaron correlaciones entre MM y PMM con VIFT o VO2máx. Conclusión: Es posible concluir que el rendimiento en el 30-15IFT presenta asociación con la composición corporal, específicamente con la MA, S6P e IMC en las jugadoras evaluadas.

Abstract Background: The participation of women in football has increased exponentially in recent years, so integrating evidence-based background in this population allows a better understanding and analysis of the sporting performance of female athletes. Objective: Determine the level of association between body composition indicators and performance in the 30-15 IFT test in first division female football players. Methods: 29 professional female players from a first division team in Chile participated. The 30-15 test was evaluated, the final velocity achieved (VIFT) was analyzed, and the maximum oxygen consumption (VO2máx) was estimated. Body composition (CC) was estimated through anthropometry and height, body mass, body mass index (BMI), absolute (AM) and relative (RM) adipose mass, absolute (MM) and relative (RMM) muscle mass, and 6-fold sum (S6P) were analyzed. Pearson's correlation coefficient (r) with an alpha of 0.05 was used to analyze the level of association. Results: Weak negative correlations were found between MA with VIFT (r = -0.384 and p = 0.04) and VO2máx (r = -0.375 and p = 0.45); moderate negative correlations between S6P with VIFT (r = -0.476 and p = 0.009) and VO2máx (r = 0.454 and p = 0.013); moderate negative correlations between BMI with VIFT (r = 0.401 and p = 0.031) and VO2máx (r = -0.379 and p = 0.043). No correlations were found between MM and PMM with VIFT or VO2máx. Conclusion: It is possible to conclude that performance in the 30-15IFT is associated with body composition, specifically with MA, S6P, and BMI in players evaluated.

RESUMEN

Abstract Introduction: In recent decades, the level of skiing performance in Russia has decreased significantly. This has necessitated problems with the preparation of athletes for competitions and the training process. Objective: To analyze the effects of simulation training tools on the physical condition of ski racers aged 13-14 years. Methods: Quasi-experimental, non-randomized study. 40 cross-country skiers aged 13-14 years belonging to the Korshik Village sports school (Russia) were assigned to a control (n = 20) and experimental (n = 20) group. Classes in the control group were conducted according to the usual training plan and in the experimental group simulation exercises were used. The control tests included pull-ups, squats, two-legged long jump, simulated 100-meter climbing and a 500-meter running test. Results: The control group showed no significant improvements (p > 0.05), while the experimental group reported significant improvements in pull-ups (22.2%; p< 0.05), squat (5.9%; p< 0.05), two-legged long jump (6.8%; p< 0.05), 100-meter climbing simulation (7.8%; p< 0.05) and 500-meter run (4.2 %, p <0.05). Conclusion: If, in the preparatory period, a series of simulation exercises are included in the training program for skiers aged 13-14 years, the level of physical fitness of athletes will improve significantly.

RESUMEN

Background: This systematic review and meta-analysis aimed to assess the impact of inspiratory muscle training (IMT) on lung function parameters (MIP, MEP, FEV1, and FVC) between both elite and non-elite swimmers. Methods: We searched for controlled clinical trials (CCT) and prospective longitudinal studies (PLS) in elite and non-elite swimmers following an inspiratory muscle training (IMT) protocol with a standardized device, published between 2012 and 2023. The databases used in the search were PubMed, Science Direct, Scopus, Springer, Cochrane Central Register of Controlled Trials, and Google Scholar. The primary outcome assessed was the impact of IMT on lung function parameters, including MIP, MEP, FEV1, and FVC. Results: We selected 13 articles involving 277 subjects aged 11-21 years, with 61.4% being male, and 84.6% being elite swimmers. The most commonly used IMT device was the PowerBreathe®, prescribed for 3-12 weeks, 1-2 sessions per day, 3-6 times per week, with 30 repetitions, starting at 50% of MIP and progressing up to 80%. The meta-analysis showed that IMT was associated with a higher MIP (MD = 29.35 cmH2O, 95% CI: 13.04-45.65 cmH2O, p < 0.01) without affecting FEV1 and FVC. Conclusion: The swimmers that used IMT improved muscle strength, specifically MIP, without changes in MEP, FEV1, and FVC.

RESUMEN

Instruments used to assess the mental well-being of young athletes in Brazil are scarce. Therefore, the present study aimed to translate, cross-culturally adapt for young athletes, and gather evidence of validity for the Sport Mental Health-Short Form (S-MHC) for use in Brazilian Portuguese. The research was conducted in five stages: translation, synthesis, back-translation, expert review, and validation of the psychometric properties. For validation, 246 young athletes of both genders (88 females, 35.8%), aged between 12 and 18 years (14.5 ± 1.9 years), were recruited. Psychometric methods were employed to confirm and validate the translated and adapted versions of the S-MHC for young athletes, including internal consistency using Cronbach's alpha and McDonald's omega, composite reliability, Item Characteristic Curve (ICC) using Item Response Theory (IRT), and Confirmatory Factor Analysis (CFA). Two structures were tested, with Model 1 loading the 14 items of the translated version of the S-MHC into a single latent factor and Model 2 loading the items into three factors related to emotional, social, and psychological sport well-being. Both models showed good validity, consistency, and reliability measures and can be used to investigate the sport well-being of young athletes. It was concluded that the translated version of the S-MHC in Brazilian Portuguese can be used to assess the sport well-being of young athletes in Brazil. Model 2 structure is recommended to observe the different nuances of emotional, social, and psychological well-being.

RESUMEN

BACKGROUND: The World Health Organization recognizes that physical activity (PA) during childhood is crucial for healthy development, aligning well with the achievement of several United Nations (UN) Sustainable Development Goals (SDGs). This study aimed to explore the associations between 10 key indicators of PA for children and adolescents assessed in the Global Matrix 4.0 project, and the UN SDGs. METHODS: Data from 57 countries/jurisdictions of the Global Matrix 4.0 project were used. The UN SDG indicators were sourced from the SDG Transformation Center, which publishes each country's performance on each of the 17 SDGs. Given the robust evidence supporting plausible links between PA and SDGs 3 (good health and well-being), 9 (industry, innovation, and infrastructure), 11 (sustainable cities and communities), 13 (climate action), and 16 (peace, justice, and strong institutions), these SDGs were investigated. RESULTS: Countries/jurisdictions with good and moderate performance in achieving SDG 3, SDG 9, SDG 11, and SDG 16 had higher grades than countries/jurisdictions with fair performance in achieving these SDGs for the following indicators: Organized Sports and PA, Community and Environment, and Government Investments and Strategies. However, countries/jurisdictions with good performance in achieving SDG 13 had lower grades than countries/jurisdictions with fair performance in achieving SDG 13 for the following indicators: Organized Sports and PA, Community and Environment, and Government Investments and Strategies. CONCLUSIONS: Organized Sports and PA, Community and Environment, and Government Investments and Strategies were the indicators that demonstrated differences between countries/jurisdictions with good and poor performance in achieving the SDGs.

RESUMEN

BACKGROUND: Physical activity in natural environments, such as trail running, is a way to nurture physical and mental health. However, running has an inherent risk of musculoskeletal injuries. OBJECTIVES: To investigate the prevalence of running-related injuries (RRI) and cramps, and to describe the personal and training characteristics of Brazilian trail runners. METHODS: A total of 1068 trail runners were included in this observational cross-sectional study. The participants had at least six months of trail running experience. The data were collected between April 2019 and February 2020 through an online and self-reported survey. RESULTS: The point prevalence of RRIs was 39.2 % (95 % credible interval [CrI]: 36.3, 42.1). The body region with the highest point prevalence was the knee. The 12-month period prevalence of RRIs was 69.2 % (95 %CrI: 66.4, 72.0). The body region with the highest 12-month period prevalence was the lower leg. 1- and 12-month period prevalence of cramps was 19.5 % (95 %CrI: 17.1, 21.9) and 36.0 % (95 %CrI: 33.0, 38.8), respectively. Triceps surae was the muscle most affected by cramps. CONCLUSIONS: Two in 5 (40 %) trail runners reported being injured at the time of data collection, and about 2 of 3 reported previous RRIs in the last 12 months. The most prevalent injured body regions were the knee and the lower leg. One in 5 trail runners reported cramps in the last month, increasing to 36 % in the last 12 months. Knowing better the characteristics of the population and the burden of health conditions may inform better decisions regarding implementation actions toward trail running practice.

RESUMEN

For judo athletes with visual impairments and their coaches, understanding possible muscle adaptations can be challenging. As it is commonplace for these adaptations to include interlimb asymmetry, we analyzed the magnitude and direction of interlimb asymmetry in judo athletes with visual impairments and verified the association of this asymmetry with their unilateral physical performances. Participants were 18 elite judo athletes (10 male, 8 female) with visual impairments. These athletes performed three physical tests: countermovement jump (CMJ), medicine ball throw (MBT), and handgrip strength (HGS), while we conducted unilateral right and left side assessments using the interlimb asymmetry equation for each physical test. Our main results showed that the CMJ and MBT tests presented asymmetry values above 10%; with CMJ significantly higher than HGS (p = 0.050), and with inconsistencies across the three tests in the direction of interlimb asymmetry (k = -0.22-0.26). Unilateral CMJ (left limb) was negatively correlated with asymmetry (r = -0.51; p = 0.031), and unilateral MBT (right limb) was positively correlated with asymmetry (r = 0.52; p = 0.024). Based on these results, coaches should prioritize regular assessments of interlimb asymmetry using these specific tests. This data can guide the construction of training programs aimed at minimizing asymmetry and enhancing overall physical performance. Continuous monitoring and adjustment of training strategies based on asymmetry findings are crucial for optimizing muscle balance in judo athletes with visual impairments.

RESUMEN

This study aims to identify contextual situations (score, game time, the interaction between teammates and opponents, start and restart plays) that increase the odds ratio of maintenance of ball possession and scoring a goal. Twenty professional futsal players were evaluated in seven home official matches. The games were filmed to analyze the offensive actions. In total, 828 attacking plays were analyzed. The absence of defensive pressure from the opponent resulted in a greater odds ratio (OR) for loss of ball possession (OR = 1.7, 95% CI = 1.7 to 2.2), but also increased total effectiveness (OR = 6.5; 95%CI = 2.2 to 19.5). The received fouls did not increase the total effectiveness (OR = 0.2; 95%CI = 0.01 to 4.2; p = 0.40). The court regions close to the opponent's goal area and areas where there was less defensive pressure had a higher frequency of goals (p < 0.05). The results demonstrated that shooting close to opponents' areas and having no defensive pressure were the situations with increased odds of goal-scoring. Maintaining ball possession per se did not increase the OR of goal scoring, however situations when shootings were performed with low defensive pressure could increase chances of goal scoring.

RESUMEN

BACKGROUND: Wheelchair racing is a traditional modality of Paralympic athletics. In general, racing wheelchairs are customized according to the athletes' anthropometric conditions, based on pre-established dimensions according to the manufacturer's manual. Usually, athletes choose the dimensions for their new sports wheelchairs, and when they are delivered for use, they often have problems due to incorrect body adjustments. PURPOSE: To develop a new customization methodology that is made possible through a new multi-adjustable racing wheelchair prescription equipment (RWPE) for athletics. This equipment performs several measurements and adjustments according to the athlete's anthropometric characteristics, evaluating the best-fit athlete to obtain better performance in the personalized wheelchair. MATERIALS AND METHODS: Customizing racing wheelchairs is based on anthropometric measurements of the individual and specific ergonomic adjustments for better performance and safety. The RWPE is a multi-adjustment device composed of modules that use measuring instruments to guarantee maximum precision and accuracy of the assessments. This project's innovation is associated with the multi-regulation equipment itself and a conventional process of manufacturing a racing wheelchair through an online form. The RWPE has a robust and rigid structure for conducting race-track experimental tests. RESULTS AND CONCLUSIONS: The experimental tests allowed the equipment to be validated regarding safety, comfort, and prescription methodology. A high-performance athlete validated the equipment and prescription methodology, and as a result, a new version of a parameterized wheelchair was also developed using the prescription methodology. A comparison between prescription tests showed better athlete performance regarding estimated average power, considering dimensions optimized through RWPE.

Sport provides many benefits to people with disabilities, including physical and emotional benefits during rehabilitation. Therefore, this work provides a better adaptation of the athletes to their racing wheelchair, benefiting these athletes with better conditions to practice the sport and a smoother rehabilitation with less stress.When a racing wheelchair is prescribed for an athlete it needs to be suited to the individual's posture. Incorrectly prescribed racing wheelchairs can cause serious damage to the athlete's health. In this way, this work encourages better collaboration with practitioners of the sport during prescription of their racing wheelchair.In addition to being used for prescription racing wheelchairs, the presented equipment can also be used for training, physical conditioning and rehabilitation of people with disabilities.

RESUMEN

Teres major injuries are rare and are generally treated conservatively, except in high-performance athletes. This report describes a case of traumatic rupture of the teres major at its myotendinous junction in a professional gymnast. The patient underwent surgical treatment 10 days after the injury. Six months post-surgery, the patient achieved complete recovery of the range of motion and strength, returning to the pre-injury performance level, guided by physiotherapy rehabilitation. This is the first documented case in the literature of surgical treatment of this injury in a professional gymnast. The main lesson from this case is that early surgical repair in elite athletes can result in excellent functional outcomes and allow return to sport at the pre-injury performance level.

RESUMEN

BACKGROUND: The impact of cardiorespiratory fitness (CRF) on cognition is thought to be mediated by brain-derived neurotrophic factor. Aerobic exercise can increase CRF through various activities, including sports participation. The relationship between these factors in females has yet to be elucidated. OBJECTIVE: This review aims to map the current literature on the effects of aerobic exercise, sports participation, and CRF in healthy adult females, with sub-topics of pregnancy and menstrual cycle periodicity. METHODS: A scoping review of the literature was conducted following PRISMA guidelines and the PCC mnemonic (population, concept, and context). The following five databases were screened: CINAHL, Medline, Web of Science, SPORTDiscus, and Scopus. Eligible articles included healthy adult females, investigated aerobic exercise, sports participation or CRF, and linked outcomes to cognition. Data from included manuscripts was extracted and analyzed. Two sub-population groupings (pregnant individuals and menstrual cycle) were established to further aid the interpretation of the findings. RESULTS: Of the 300 titles and abstracts screened, 74 were eligible for full-text screening, and 28 were included in the scoping review. Of the 28 included, 14 did not control for or report on menstrual cycle phase or sex hormones. CONCLUSION: This scoping review found an inverse 'U' relationship between aerobic exercise and cognition, demonstrating an optimal dose of aerobic exercise to benefit cognitive functions. As estrogen may impact the relationship between CRF and neural growth factors, more research is needed on this pathway, independent of the menstrual cycle, to determine potential beneficial effects. It is currently unknown whether sports participation can independently impact cognition.

RESUMEN

PURPOSE: To characterize the time structure of K1 kickboxing matches of Glory World Series (Glory) and to determine potential differences between winners and losers. METHODS: Seventeen matches of Glory 2019 (17 first rounds, 13 second rounds, and 8 third rounds) were video-analyzed to quantify (1) the time expended in high- and low-intensity activity and pauses, (2) the number and pattern of attacks, and (3) the number of effective attacks. Fighters were professional male athletes (age 27.9 [2.7] y) of the middle-weight category (85 kg). The number and the pattern of attacks and the number of effective attacks were compared between winners and losers. RESULTS: The mean times expended in high- and low-intensity activity and pauses were 234.6 (133.9) seconds, 97.4 (60.1) seconds, and 36.0 (19.9) seconds, respectively, resulting in an effort-to-pause ratio of ∼1.8:1. Compared with losers, winners presented (1) a greater number of attacks in the second round (P = .004) and entire match (P = .009), (2) a greater number of attacks containing 3 attacks in sequence in the second round (P = .001) and attacks containing >3 attacks in the third round (P = .049), and (3) a greater number of effective attacks in the second round (P = .011) and entire match (P = .008). CONCLUSIONS: The findings of the present study indicate that K1 kickboxing in Glory matches presents a ∼1.8:1 effort-to-pause ratio and that winners perform more attacks, effective attacks, and attacks in sequence. These data provide useful insights to improve the training specificity of kickboxing athletes.

RESUMEN

BACKGROUND: The elevated blood pressure (BP) and lower cardiac autonomic modulation (CAM) are associated with higher morbidity mortality risk among older adults. Although exercise is an important intervention for cardiovascular promotion, it is unclear whether combat sports training could benefit cardiovascular outcomes as much as autonomic in this population. This study compared the effects of 12 weeks of Muay Thai (MT) training against functional training (FT) on CAM and hemodynamic parameters in older adults. METHODS: The sample consisted of 50 older adults (41 women; 66.0 ± 5.3 years old), who were equaly randomized into FT (n = 25) and MT (n = 25) intervention groups. CAM was measured by 30-min rest heart rate variability. Systolic blood pressure (SBP), diastolic blood pressure (DBP) and resting heart rate (RHR) were measured using an automatic oscillometric device. Pulse pressure (PP) and the double product (DP) were also calculated. The interventions were carried out three times a week, with 60-min length per session, during 12 consecutive weeks. The intensity of the interventions was measured using the subjective perception of exertion scale and by accelerometer. Two-factor repeated measures analysis of covariance was used for groups comparison, considering intervention group and body mass as factors. The 95% confidence interval of the difference (95%CIdif) was also calculated and the effect size was measured using partial eta squared (η2p). RESULTS: CAM indices did not show significant changes across moments and intervention groups. In hemodynamic parameters, only in DBP was there an effect of the moment (F1,39 = 8.206; P = 0.007; η2p = 0.174, large) and interaction effect between group*moment (F1,39 = 7.950; P = 0.008; η2p = 0.169, large). Specifically, the MT group at the post-training moment showed lower DBP (P = 0.010; 95%CIdif = -13.3; -1.89) in relation to the FT group. Furthermore, the MT group showed a decrease in DBP during training (P = 0.002; 95%CIdif = -10.3; -2.6). Also, an increase in training intensity was also found over the 12 weeks in FT, with no difference between the groups. CONCLUSION: After 12 weeks of MT practice there was a reduction in DBP compared to FT in older adults. TRIAL REGISTRATION: NCT03919968 Registration date: 01/02/2019.
