The purpose of the present study was to compare the changes in muscle strength in nontrained young males performing resistancetraining under different supervision ratios. One hundred twenty-four young men were randomly assigned to groups trained under a high (HS, 1:5 coach to athlete ratio) or low (LS, 1:25) supervision ratio. Both groups performed identical resistance […]

The present study aimed at comparing the effects of traditional resistance training (TRT) and power training (PT) in inducing muscle hypertrophy in older men. Twenty older men (aged between 69 and 76 years) were divided in two groups: TRT training (n=9) and PT training (n=11). The volunteers trained twice a week, during 10 weeks. Both

Introdução: Estudos têm demonstrado que a duração do intervalo de recuperação (IR) entre as séries do exercício resistido (ER) afeta o número de repetições das séries subsequentes. Objetivo: investigar os efeitos de três diferentes intervalos de recuperação (IR) entre as séries do exercício resistido (ER) sobre o número de repetições (volume) em mulheres jovens treinadas.

The current study investigated the association between vitamin-D-receptor (VDR) genotypes with bone-mineral density (BMD) and its interaction with physical activity level (PAL). Individuals in a sample of 192 volunteers (67.84 +/- 5.23 years) underwent BMD evaluation and were genotyped for VDR ApaI, BsmI, FokI, and TaqI polymorphisms. Haplotypes were reconstructed through expectation-maximization algorithm, and regression-based

O treinamento resistido vem sendo apontado como eficaz em retardar o declínio de força e massa muscular que acompanham o envelhecimento; contudo, a resposta hormonal aguda a esse tipo de exercício precisa ser mais bem caracterizada. Os objetivos do presente estudo foram caracterizar e comparar as respostas hormonais agudas resultantes de diferentes intensidades de exercícios

The present study investigated the interaction between Cdx-2 polymorphism and physical activity level over bone mineral density (BMD) variation in Brazilian postmenopausal women. One hundred and ninety women volunteered to participate in the study (66.6 +/- 5.3 years, 64.58 +/- 11.74 kg and 151.94 +/- 6.36 cm). Physical activity level (PAL) was assessed using the

Acute cardiovascular responses to different high-velocity resistance exercise protocols were compared in untrained older women. Twelve apparently healthy volunteers (62.6 ± 2.9 y) performed three different protocols in the bench press (BP). All protocols involved three sets of 10 repetitions performed with a 10RM load and 2 minutes of rest between sets. The continuous protocol

With the purpose of manipulating training stimuli, several techniques have been employed to resistance training. Two of the most popular techniques are the pre-exhaustion (PRE) and priority system (PS). PRE involves exercising the same muscle or muscle group to the point of muscular failure using a single-joint exercise immediately before a multi-joint exercise (e.g., peck-deck

This study investigated the acute hormonal response to three different rest periods between sets of a traditional lower body resistancetraining session in young women. Twelve healthy trained females (26.83+/-3.93 years) participated in the study. On three separate sessions of a lower body resistance exercise protocol, subjects were assigned in a random order a rest interval

The relationship between vitamin D receptor (VDR) ApaI, CDX2, BsmI, FokI, and TaqI polymorphisms and fat-free mass (FFM) were examined in 191 postmenopausal Brazilian women (mean age 67.87 +/- 5.22 years). Participants underwent FFM measurements by dual-energy x-ray absorptiometry (DEXA). Whole-blood-extracted genomic DNA was genotyped to the aforementioned polymorphisms and to ancestry-informative markers through minisequencing,
