Training attendance is an important variable for attaining optimal results after a resistance training (RT) program, however, the association of attendance with the gains of muscle strength is not well defined. Therefore, the purpose of the present study is to verify if attendance would affect muscle strength gains in healthy young males. Ninety two young […]

The aim of this study was to examine the effect of adding single-joint (SJ) exercises to a multi-joint (MJ) exercise resistance-training program on upper body muscle size and strength. Twenty-nine untrained young men participated in a 10-week training session. They were randomly divided in 2 groups: the MJ group performed only MJ exercises (lat pulldown

Objectives: To investigate the effects of resistance training volume on the adaptations of different muscle groups in untrained young men. Equipments and methods: The volunteers were randomly assigned into two groups: (1) three sets of knee extension and a single set of elbow flexion (3K-1E; n = 11), or (2) single set of knee extension and three

Objetivo: analisar os indícios na literatura sobre os efeitos do treinamento resistido como forma de intervenção na reabilitação de pacientes com lesão medular traumática ao longo do tempo. Método: Fontes das informações: uma busca sistematizada da literatura em cinco bancos de dados (MEDLINE, LILACS, SciELO, IBECS e Biblioteca Cochrane) foi realizada até agosto de 2010.

The R577X polymorphism at the ACTN3 gene has been associated with muscle strength, hypertrophy and athletic status. The X allele, which is associated with the absence of ACTN3 protein is supposed to impair performance of high force/velocity muscle contractions. The purpose of the present study was to investigate the association of the R577X polymorphism with

Comparisons between men and women of time course responses of strength, delayed-onset muscle soreness (DOMS), and muscle swelling after a resistance training session are still controversial. Therefore, this study examined gender differences in strength loss, muscle thickness (MT), and DOMS between young men and women. Thirty apparently healthy, untrained volunteers (14 women and 16 men)

BACKGROUND: Population stratification is the main source of spurious results and poor reproducibility in genetic association findings. Population heterogeneity can be controlled for by grouping individuals in ethnic clusters; however, in admixed populations, there is evidence that such proxies do not provide efficient stratification control. The aim of this study was to evaluate the relation

Introduction: Previous studies have attempted to link the insertion/deletion (I/D) polymorphism in the angiotensin-converting enzyme (ACE) gene with the variability in muscle strength responses to resistance training (RT); however, the literature is inconclusive. The purpose of the present study was to investigate the association between the ACE I/D genotype and muscle strength response to a

The aim of this study was to evaluate and compare acute effects of a reciprocal action protocol and a super-set protocol on knee extensor performance during concentric isokinetic exercise. Fourteen men aged 29.4+6.1 years were tested on three different protocols, with 1 min of rest between sets: control (3 sets of 10 isokinetic knee extension

The purpose of the study was to investigate the effects of different between-set rest interval durations on muscle strength after 12 weeks of resistance training. After baseline tests, 34 nonresistance trained college-aged men were matched and randomly assigned to 2 groups. Both groups trained twice a week and performed the same exercises and the same
