Effects of different resistance training frequencies on body composition, muscular strength, muscle quality, and metabolic biomarkers in sarcopenic older women. J Strength Cond Res 38(9): e521-e528, 2024-Resistance training (RT) can ameliorate outcomes related to sarcopenia by promoting beneficial changes in muscular strength, skeletal muscle mass (SMM), and muscle quality. This study compared the effects of 12 weeks of RT performed 2 and 3 sessions a week on body composition, muscular strength, muscle quality, and metabolic biomarkers in sarcopenic older women. Thirty-four sarcopenic older women (>60 years) were randomly assigned to perform a whole-body RT program, either 2 (G2X, n = 18) or 3 (G3X, n = 16) sessions a week during 12 weeks (8 exercises, single set of 10-15 repetitions). Body composition, muscular strength, muscle quality, and metabolic biomarkers were assessed before and after the intervention. Both groups increased (p < 0.05) 1 repetition maximum total muscular strength (G2X = +20.4% and G3X = +21.0%), SMM (G2X = +4.0% and G3X = +7.0%), and improved muscle quality (G2X = +16.7% and G3X = +13.6%), with no differences between groups (p > 0.05). No change over time was found for IGF-1 and testosterone (p > 0.05). Our results suggest that 12 weeks of RT performed at a lower weekly frequency is as effective as a higher frequency in improving muscular strength, SMM, and muscle quality in sarcopenic older women.

RESUMEN

PURPOSE: The optimal intensity of resistance training (RT) to improve muscular, physical performance, and metabolic adaptations still needs to be well established for older adults. Based on current position statements, we compared the effects of two different RT loads on muscular strength, functional performance, skeletal muscle mass, hydration status, and metabolic biomarkers in older women. METHODS: One hundred one older women were randomly allocated to perform a 12-wk whole-body RT program (eight exercises, three sets, three nonconsecutive days a week) into two groups: 8-12 repetitions maximum (RM) and 10-15RM. Muscular strength (1RM tests), physical performance (motor tests), skeletal muscle mass (dual-energy X-ray absorptiometry), hydration status (bioelectrical impedance), and metabolic biomarkers (glucose, total cholesterol, HDL-c, HDL-c, triglycerides, and C-reactive protein) were measured at baseline and posttraining. RESULTS: Regarding muscular strength, 8-12RM promoted higher 1RM increases in chest press (+23.2% vs +10.7%, P < 0.01) and preacher curl (+15.7% vs +7.4%, P < 0.01), but not in leg extension (+14.9% vs +12.3%, P > 0.05). Both groups improved functional performance ( P < 0.05) in gait speed (4.6%-5.6%), 30 s chair stand (4.6%-5.9%), and 6 min walking (6.7%-7.0%) tests, with no between-group differences ( P > 0.05). The 10-15RM group elicited superior improves in the hydration status (total body water, intracellular and extracellular water; P < 0.01), and higher gains of skeletal muscle mass (2.5% vs 6.3%, P < 0.01), upper (3.9% vs 9.0%, P < 0.01) and lower limbs lean soft tissue (2.1% vs 5.4%, P < 0.01). Both groups improved their metabolic profile. However, 10-15RM elicited greater glucose reductions (-0.2% vs -4.9%, P < 0.05) and greater HDL-c increases (-0.2% vs +4.7%, P < 0.01), with no between-group differences for the other metabolic biomarkers ( P > 0.05). CONCLUSIONS: Our results suggest that 8-2RM seems more effective than 10-15RM for increasing upper limbs' muscular strength, whereas the adaptative responses for lower limbs and functional performance appear similar in older women. In contrast, 10-15RM seems more effective for skeletal muscle mass gains, and increased intracellular hydration and improvements in metabolic profile may accompany this adaptation.

ABSTRACT: Cunha, PM, Ribeiro, AS, Padilha, C, Nunes, JP, Schoenfeld, BJ, Cyrino, LT, Tomeleri, CM, Nascimento, MA, Antunes, M, Fernandes, RR, Barbosa, DS, Venturini, D, Burini, RC, Sardinha, LB, and Cyrino, ES. Improvement of oxidative stress in older women is dependent on resistance training volume: Active aging longitudinal study. J Strength Cond Res 36(4): 1141-1146, 2022-The purpose of the present study was to investigate the effects of resistance training (RT) performed with a higher versus lower training volume on oxidative stress (OS) biomarkers in older women. Thirty-eight older women (≥60 years) were randomly assigned to 1 of 2 groups: a group that performed 1 set per exercise (low volume [LV], n = 18) or 3 sets per exercise (high volume [HV], n = 20). The whole-body RT consisted of a 12-week RT program involving 8 exercises performed with sets of 10-15 repetitions maximum, 3 days per week. Advanced oxidation protein products (AOPP), total radical-trapping antioxidant parameter (TRAP), and ferrous oxidation-xylenol orange (FOX) were used as OS biomarkers. The composite Z-score of the percentage changes from pre- to posttraining of OS biomarkers according to groups was calculated. A significant main effect of time (p < 0.05) was found for AOPP (LV = -7.3% vs. HV = -12.2%) and TRAP (LV = +1.5% vs. HV = +15.5%) concentrations, without a statistical difference between the groups (p > 0.05). A significant group vs. time interaction (p < 0.001) was revealed for FOX (LV = +6.4% vs. HV = -8.9%). The overall analysis indicated higher positive changes for HV than LV (composed Z-score: HV = 0.41 ± 1.22 vs. LV = -0.37 ± 1.03; p < 0.05). Our results suggest that a greater volume of RT seems to promote superior improvements on OS biomarkers in older women.

RESUMEN

PURPOSE: Resistance training (RT) combined with appropriate dietary intake can promote a concomitant increase in skeletal muscle mass (SMM) and reduction in fat mass, a condition termed body recomposition. This study's primary purpose was to explore the effects of protein ingestion on body recomposition after 24 wk of RT in older women. METHODS: Data from 130 untrained older women (68.7 ± 5.6 yr, 66.5 ± 11.5 kg, 155.5 ± 6.0 cm, and 27.4 ± 4.0 kg·m-2) across six studies were retrospectively analyzed. The participants were divided into tertiles according to their customary protein intake (g·kg-1·d-1): lower (LP; n = 45), moderate (MP; n = 42), and higher (HP; n = 43) protein intake. Participants performed a whole-body RT program carried out over 24 wk (eight exercises, three sets, 8-15 repetitions, three sessions a week). SMM and fat mass were determined by dual-energy x-ray absorptiometry. RESULTS: All groups increased SMM from baseline (P < 0.05), with the HP and MP groups showing greater increases than the LP group (LP, 2.3%; MP, 5.4%; and HP, 5.1%; P < 0.05). Reductions in fat mass were similar for all three groups (LP, 1.7%; MP, 3.7%; and HP, 3.1%; P > 0.05). The composite z-score of the percentage changes from pretraining to posttraining indicated greater positive body recomposition values for HP and MP compared with LP (P < 0.05). CONCLUSIONS: Results suggest that protein intake is a moderating variable for body recomposition in older women undergoing RT, with a low protein intake having a less favorable effect on body recomposition.

RESUMEN

We compared the effects of different resistance training (RT) volume reduction strategies on muscular strength and lean soft-tissue (LST) in older women. Fifty-seven physically independent women (>60 years) performed a 20-week pre-conditioning phase of a standardized whole-body RT program (eight exercises, three sets, 8-12 repetitions, three sessions a week), and were then randomly assigned to one of the following conditions: reduced volume for a single set (RV1, n=20) or two sets (RV2, n=19), or maintained volume of three sets (MV, n=18) for 8 weeks (specific training phase). Muscular strength in the chest press, leg extension, and preacher curl exercises was determined by one-repetition maximum tests. A dual-energy X-ray absorptiometry device was used to estimate LST. An increase in muscular strength (16.3-32.1%) and LST (3.2-7.9%) was observed after the pre-conditioning phase. There was an increase in chest press for all groups (9.4-16.7%) after the specific training phase. In contrast, only MV increased significantly in the leg extension (4.4%). No between-group differences were revealed for LST in the specific training phase. Our results suggest that reduced RT volume from three to one set per exercise for 8 weeks seems sufficient to retain neuromuscular adaptations in older women.

RESUMEN

Cunha PM, Nunes JP, Tomeleri CM, Nascimento MA, Schoenfeld BJ, Antunes M, Gobbo LA, Teixeira D, and Cyrino ES. Resistance training performed with single and multiple sets induces similar improvements in muscular strength, muscle mass, muscle quality, and IGF-1 in older women: A randomized controlled trial. J Strength Cond Res 34(4): 1008-1016, 2020-The purpose of this study was to compare the effects between single set vs. multiple sets of resistance training (RT) on measures of muscular strength, muscle mass, muscle quality (MQ), and insulin-like growth factor 1 (IGF-1) in untrained healthy older women. Sixty-two older women were randomly assigned to 1 of the 3 groups: single-set RT (SS, n = 21), multiple-sets RT (MS, n = 20), or nontraining control (CG, n = 21). Both training groups performed RT for 12 weeks, using 8 exercises of 10-15 repetitions maximum for each exercise. The SS group performed only 1 set per exercise, whereas MS performed 3 sets. Anthropometry, muscle strength (1RM tests), lean soft tissue (LST), and MQ from upper limbs (UL) and lower limbs (LL), and IGF-1 were measured before and after training. Both training groups showed significant pre-training to post-training increases for UL1RM (SS: 37.1%, MS: 27.3%, CG: -3.0%), LL1RM (SS: 16.3%, MS: 21.7%, CG: -0.7%), ULLST (SS: 7.8%, MS: 8.8%, CG: -1.1%), LLLST (SS: 5.6%, MS: 6.3%, CG: -0.8%), upper-limb muscle quality (SS: 25.2%, MS: 16.7%, CG: -0.2%), lower-limb muscle quality (SS: 10.5%, MS: 15.4%, CG: -3.5%), and IGF-1 (SS: +7.1%, MS: +10.1%, CG: -2.2%). We conclude that both SS and MS produce similar increases in muscular strength, LST, and MQ of upper and lower limbs, and IGF-1 after 12 weeks of RT in untrained older women. Our results suggest that, in the early stages, the RT regardless number of sets is effective for improving muscular outcomes in this population.

RESUMEN

The aims of this study were: (i) to analyze the relationship between the performance of different measures of muscular strength, and (ii) to identify which measurements present a greater relationship with an overall strength score. Sixty older women (aged 69 ± 6 years) were submitted to muscular strength measurements from isotonic, isokinetic, and isometric tests. An overall-strength score was generated with z-scores of the values obtained in all tests. Interquartile intervals were created for each measure and the overall-strength score. Pearson's r (0.463-0.951, p < 0.05) and Cronbach's α (0.500-0.966) suggested that subjects had relatively similar strength performance compared to their peers in the different tests. Greater associations were observed between tests for similar tasks. In addition, strong-magnitude associations were revealed between all the tests and the overall-strength score (r = 0.710-0.806; α = 0.760-0.846). Factor analysis identified that only two principal components may be sufficient to explain the strength of the sample. All strength measures had high loadings (0.716-0.916) on a common factor with 1 component. The associated eigenvalue with 2 components was 6.8 (84% of the variance). The present results support the phenomenon of the generality of strength in older women. Although greater correlations were observed for tests performed at the same joint, movement, or type of muscular action, the eight tests satisfactorily represented a measure of general muscular strength cross-sectionally.

RESUMEN

BACKGROUND AND PURPOSE: There is a growing body of evidence indicating that phase angle (PhA) can be used as an indicator of nutritional status, disease prognosis, and mortality risk; however, it is still unknown whether PhA can be used as an explanator of functional capacity and muscle quality in older women. The main purpose of this cross-sectional study was to explore whether PhA is associated with muscle quality and functional capacity in older women, regardless of total and regional body composition. METHODS: A total of 125 older women-66.7 (4.7) years; 65.6 (10.9) kg body mass; 156.1 (5.2) cm height; 26.9 (4.0) kg/m body mass index-participated in this study. Anthropometric, PhA, body composition (whole-body dual-energy x-ray absorptiometry) and muscle quality (defined as total muscular strength per kilogram of appendicular lean soft tissue) were measured. The functional capacity was assessed by 4 tests: 10-m walk test, rising from sitting position, rising from ventral decubitus position, and rising from a chair and walking around the house. The summing z-scores for the 4 tests was used as a continuous functional capacity score. Linear regression analysis was conducted to test whether PhA is related to the dependent variables (muscle quality and functional capacity), after adjusting for potential covariates. RESULTS: The PhA presented a small-to-moderate relationship with muscle quality (r = 0.27; P < .01) and functional capacity (r = 0.31; P < .01), respectively. These relationships remained significant after adjustment for age, lower limb lean soft tissue, and total fat mass for muscle quality (ß= 0.55; P < .01) and functional capacity (ß= 1.38; P < .01). CONCLUSION: Our findings suggest that healthy elderly women with higher values of PhA have a better muscle quality and functionality, regardless of age and body composition.

RESUMEN

This study aimed to analyze the effects of a pyramid system performed with two repetition zones on muscular strength and skeletal muscle mass (SMM) in older women. Thirty-nine physically independent older women (67.8±5.4 years) were randomly assigned into one of two of groups that performed an 8-week resistance training program in an ascending pyramid fashion. Both groups performed 3 sets: a narrow repetition zone (NPR, n=20) with 12/10/8 repetitions, and a wide repetition zone (WPR, n=19) with 15/10/5 repetitions. The program consisted of 8 whole-body exercises, performed 3 times a week. Dual-energy X-ray absorptiometry was used to measure SMM, and muscular strength was evaluated by one-repetition maximum (1RM). Both groups increased (P<0.05) SMM (NPR=+ 4.7%, effect size=+ 0.34; WPR=+ 8.4%, effect size=+ 0.77), and total strength (NPR=+ 11.3%, effect size=+ 0.80; WPR=+ 13.8%, effect size=0.84), without statistical differences between them. Results suggest that both zones of repetitions in a pyramid system are effective strategies to improve muscular strength and muscle growth in older women.

RESUMEN

The main purpose of this study was to compare the effects of resistance training (RT) performed with different training volumes on phase angle (PhA), body water components, and muscle quality (MQ) in untrained older adult women. A second purpose was to assess the relationship between PhA and MQ. Sixty-two older adult women (68.6 ± 5.0 years, 65.2 ± 13.3 kg, 156.1 ± 6.2 cm) were randomly assigned into one of the three groups: two training groups performed either 1 set (G1S) or 3 sets (G3S), or a control group (CG). Body water components and PhA were estimated by bioelectrical impedance (BIA). MQ was determined by dividing skeletal muscle mass estimated by dual-energy absorptiometry (DXA) by total muscle strength from three exercises. After the intervention period, both training groups demonstrated improvements (P < 0.05) when compared with CON for intracellular water, total body water, PhA, and MQ. These results suggest that RT can improve PhA, body water components, and MQ after 12 weeks of RT in untrained older women, regardless of training volume. Furthermore, changes in MQ were positively correlated with changes in PhA (r = 0.60, P < 0.01).

RESUMEN

Aging is associated with sarcopenia and dynapenia, with both processes contributing to functional dependence and mortality in older adults. Resistance training (RT) and increased protein intake are strategies that may contribute to health improvements in older adults. Therefore, the aim was to investigate the effects of whey protein (WP) supplementation consumed either immediately pre- or post-RT on skeletal muscle mass (SMM), muscular strength, and functional capacity in pre-conditioned older women. Seventy older women participated in this investigation and were randomly assigned to one of three groups: whey protein pre-RT and placebo post-RT (WP-PLA, n = 24), placebo pre-RT and whey protein post-RT (PLA-WP, n = 23), and placebo pre- and post-RT (PLA-PLA, n = 23). Each group ingested 35 g of WP or PLA. The RT program was carried out over 12 weeks (three times per week; 3 × 8⁻12 repetition maximum). Body composition, muscular strength, functional capacity, and dietary intake were assessed pre- and post-intervention. Two-way analysis of covariance (ANCOVA) for repeated measures, with baseline scores as covariates were used for data analysis. A time vs. group interaction (p < 0.05) was observed with WP-PLA and PLA-WP presenting greater increases compared with PLA-PLA for SMM (WP-PLA = 3.4%; PLA-WP = 4.2%; PLA-PLA = 2.0%), strength (WP-PLA = 8.1%; PLA-WP = 8.3%; PLA-PLA = 7.0%), and the 10-m walk test (WP-PLA = −10.8%; PLA-WP = −11.8%; PLA-PLA = −4.3%). Whey protein supplementation was effective in promoting increases in SMM, muscular strength, and functional capacity in pre-conditioned older women, regardless of supplementation timing. This trial was registered at ClinicalTrials.gov: NCT03247192.

RESUMEN

BACKGROUND: This study analyzed the effects of a 12-week resistance training (RT) program without dietary interventions on metabolic syndrome (MetS) components and inflammatory biomarkers in older women. METHODS: Fifty-three older women (mean [±SD] age 70.4 ± 5.7 years; mean body mass index 26.7 ± 4.0 kg/m2 ) were randomly assigned to a training group (TG; n = 26) that performed 12 weeks of an RT program or a control group (CG; n = 27) that did not perform any type of physical exercise over the same period. Body composition (dual energy X-ray absorptiometry), muscular strength (one-repetition maximum tests), blood pressure (BP), and blood sample measurements were performed before and after intervention. RESULTS: After the 12-week period, there were significantly reductions (P < 0.05) in glucose levels (-20.4% vs -0.3%), waist circumference (-1.5% vs +2.0%), and systolic BP (-6.2% vs +0.9%), and complete normalization of MetS prevalence (18% at baseline vs. 0% after 12-weeks RT) in the TG. Moreover, C-reactive protein and tumor necrosis factor-α concentrations decreased in the TG (-28.6% and -21.6%, respectively), but increased in the CG (+34.5% and +13.3%, respectively). In addition there were positive improvements in the MetS Z-score in the TG but not CG (-21.6% vs +13.3%, respectively). CONCLUSION: The results suggest that a 12-week RT program seems to effectively reduce MetS components and inflammatory biomarkers in older women, regardless of dietary intervention. The RT-induced adaptations in body composition and inflammatory biomarkers appear to be related to healthy adaptations in risk factors for MetS.

RESUMEN

BACKGROUND: The loss of skeletal muscle mass (MM) or muscle function (MF) alone increases the risk for losing physical independence in older adults. We aimed to examine the independent and synergic associations of low MM and low MF, both criteria of sarcopenia, with the risk for losing projected physical independence in later life (+90 years old). METHODS: Cross-sectional analyses were conducted in 3493 non-institutionalized older adults (1166 males). Physical independence was assessed with a 12-item composite physical function scale. Logistic regression was used to estimate the odds-ratio (OR) for being at risk for losing physical independence. RESULTS: Approximately 30% of the participants were at risk for losing physical independence at 90 years of age. Independent analysis demonstrated that participants with low MM had 1.65 (95%CI: 1.27-2.31) increased odds for being at risk for losing physical independence and participants with low MF had 6.19 (95%CI 5.08-7.53) increased odds for being at risk. Jointly, having a low MM and a low MF increased the risk for losing physical independence to 12.28 (95%CI 7.95 to 18.96). CONCLUSIONS: Although low MM represents a risk factor for losing physical independence, low MF seems to play a more dominant role in this relationship, with the presence of both sarcopenia criteria representing a substantial risk for losing physical independence in later life.

RESUMEN

A força muscular é um importante componente da aptidão física relacionada à saúde e ao desempenho, porém, na adolescência esta variável pode sofrer influencia de diversos fatores, dificultando assim, a análise dos resultados. Assim, objetivou-se correlacionar força muscular com indicadores ntropométricos, estágio maturacional, testes neuromotores em adolescentes de ambos os sexos. A amostra foi composta por 12 meninos (14,08±1,40 anos) e nove meninas (14,12±0,58 anos). Para avaliação da força muscular de flexão e extensão do joelho (FJ e EJ respectivamente) foi utilizado dinamômetro isocinético da marca Biodex®, seguindo um protocolo com as velocidades de 60° e 300°/s, sendo estes movimentos realizados pelo membro dominante. A composição corporal foi estimada seguindo as equações de Slaughter. Os testes motores utilizados foram: teste de impulsão horizontal, corrida de 50 metros e teste de Legér. A maturação biológica foi avaliada através da maturação sexual por meio do método auto-relatado. Os resultados mostram que a massa magra correlacionou significativamente com extensão e flexão de joelhos a 300º/s para ambos os gêneros (0,751 e 0,628 para meninos e 0,925 e 0,848 para meninas. Além disso, foram observadas correlações significativas nos meninos na extensão e flexão do joelho a 60º/s com impulsão horizontal (0,899 e 0,804, respectivamente) e teste de 50 metros (0,813 e 0,747, respectivamente). Os resultados apresentados indicam que existe uma influência multifatorial na força muscular de adolescentes, mostrando a necessidade de se considerar os aspectos morfológicos e maturacionais na análise dos resultados.(AU)

Muscle strength is an important component of physical fitness for health and performance, however, this variable during adolescence may suffer influences of various factors, thus complicating the analysis of the results. Was aimed to correlate muscle strength with anthropometric indicators, maturational stage, neuromotor tests in adolescents of both sexes. The sample consisted of 12 boys (14.08 ± 1.40 years) and nine girls (14.12 ± 0.58 years). To evaluate the muscular strength of knee flexion and extension (FJ and EJ respectively) was used isokinetic dynamometer Biodex® brand, following a protocol with speeds of 60° and 300°/sec, and these movements performed by the dominant limb. Body composition was estimated following the equations of Slaughter. The motor tests used were: standing long jump test, 50-meter sprint and Legér test. Biological maturation was evaluated by the sexual maturation by means of self-reported method. Lean mass correlated significantly with extension and knee flexion at 300°/s for both genders (0.751 and 0.628 for boys and 0.925 and 0.848 for girls. Furthermore, significant correlations were observed among boys in extension and flexion of the knee 60°/s with horizontal impulse (0.899 and 0.804, respectively) and 50 yards (0.813 and 0.747, respectively) test. The results indicate that there is a multifactorial influence muscle strength in adolescents, indicating the need to consider the morphological and maturational aspects when analyzing the results.(AU)

RESUMEN

O objetivo deste estudo foi revisar na literatura atual os métodos e variáveis do consumo máximo de oxigênio/potência aeróbia e aspectos relacionados com a capacidade aeróbia em pessoas com lesão da medula espinhal. Foi utilizada a busca através da base de dados Sciverse - com os seguintes termos: Spinal cord injury, Tetraplegia, Paraplegia cruzados com Physical endurance, Exercise tolerance, Peak oxygen consumption. Para inclusão no estudo os artigos deveriam obedecer os seguintes critérios a) avaliação da potência aeróbia em pessoas com lesão da medula espinhal na fase crônica da lesão, b) resultados com tetraplégicos ou paraplégicos, c) interação dos itens anteriores com VO2máx (l/min ou ml/kg/min) e duração de esforço em cadeira de rodas, sendo publicados a partir do ano de 2000 até o presente momento da escrita do trabalho em 2012. Após cruzamentos de termos pré-selecionados, foram selecionados 26 artigos. A partir dos estudos revisados, observa-se uma grande variação de modelos, testes e maneiras de avaliar componentes fisiológicos relacionados aos sistemas cardiorrespiratórios e circulatórios. Esta gama de métodos parece estar relacionada à heterogeneidade da população/amostra e consequentemente, os resultados, por mais similares que sejam em alguns aspectos, apresentam valores discretos de proximidade, revelando uma necessidade de padronização para estes procedimentos nesta população. Com isto, é evidente a importância de estudos bem controlados e com nível tecnológico avançado para melhores prognósticos e acompanhamentos de pessoas com lesão da medula espinhal, seja para atividades esportivas, melhora de aspectos de riscos cardiovasculares ou para o cotidiano do dia a dia.

This study aimed to review in current literature methods and variables of maximal oxygen consumption, aerobic power and aspects related to aerobic capacity in people with spinal cord injury. The survey was through the Sciverse -website with the following terms: Spinal Cord Injury, quadriplegia, paraplegia crossed with physical endurance, exercise tolerance, peak oxygen power. To be included in the study the articles should present the following criteria a) assessment of aerobic power in people with spinal cord injury in the chronic phase of the injury, b) results with quadriplegics or paraplegics, c) interaction of the above items with VO2max (l / min or ml / kg / min) and duration of effort in wheelchair, being published from year 2000 to date the year 2012. After crossing the pre-selected terms, 26 full articles were selected. From the reviewed studies, it was noticed a wide variation of models, tests and ways to evaluate physiological components related to cardiorespiratory and circulatory systems. This range of methods seems to be related to the heterogeneity of the population sample and therefore, even the results resembled in some aspects, they are discrete proximity values, revealing a necessity to standardize these procedures for this sample group. Studies well controlled with high technological level are important to establish better prognostics for people with spinal cord injuries, becoming possible to establish cardiovascular risk factors in sport practice or daily living activities in this population.
