O intervalo de recuperação afeta o volume da sessão de exercício resistido em mulheres?

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. …

Vitamin-d-receptor genotypes and bone-mineral density in postmenopausal women: interaction with physical activity

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 …

Respostas hormonais agudas a diferentes intensidades de exercícios resistidos em mulheres idosas

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 …

Physical activity, Cdx-2 genotype, and BMD

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 …

High-velocity resistance exercise protocols in older women: Effects on cardiovascular response

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 …

Effects of Exercise Order on Upper-Body Muscle Activation and Exercise Performance

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 …

Effects of rest duration between sets of resistance training on acute hormonal responses in trained women

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 …

Lack of Association Between Vitamin D Receptor Genotypes and Haplotypes With Fat-Free Mass in Postmenopausal Brazilian Women

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, …

Association Between Femoral Neck Bone Mineral Density and Lower Limb Fat-Free Mass in Postmenopausal Women

Aging is associated with several physiological changes that lead to increased disability and mortality. Examples of these changes are deteriorations in bone and muscle tissues, referred, respectively, as osteopenia and sarcopenia. Both have been linked to multiple morbid outcomes in older adults. The main purpose of this study was to determine the association between femoral …

Comparação entre a atividade EMG do peitoral maior, deltóide anterior e tríceps braquial durante os exercícios supino reto e crucifixo

A identificação das peculiaridades de cada movimento e sua adequação aos objetivos do treinamento é uma tarefa que exige a interação de vários conhecimentos. Tal tarefa é fundamental para o sucesso nas diversas modalidades esportivas e programas de treinamento com fins de reabilitação e/ou estética. O objetivo do presente estudo foi comparar a atividade eletromiográfica …
