Numerous investigations have attested to the efficacy of the National Football League (NFL)-225 test to estimate one repetition maximum (1RM) bench press. However, no studies have assessed the efficacy of the test to track changes in strength across a training program. The purpose of this study was to determine the accuracy of the NFL-225 test for determining the change in 1RM bench press in Na...

Balance disorders are a severe problem for the elderly. Exercise that can increase power of back muscles, leg muscles and dynamic balance is physical exercise in core stability (CSE). This study aimed to analyse exercise's effect on increasing muscle strength, Fifty-six elderly people aged 60-70 years were selected by simple random sampling as sample this study. The program was given CSE (n: 28...

Dear Editor-in-Chief, A recent article published in the Journal of Human Kinetics (Aráujo et al., 2014) described a postexercise hypotensive effect in hypertensive subjects after resistance exercise with blood flow restriction. The aim of this letter is to endorse the importance of further research on post-exercise hypotensive effect as a result of resistance training with blood flow restrictio...

An athletic profile should encompass the physiological, biomechanical, anthropometric and performance measures pertinent to the athlete's sport and discipline. The measurement systems and procedures used to create these profiles are constantly evolving and becoming more precise and practical. This is a review of strength and ballistic assessment methodologies used in sport, a critique of curren...

the aim of this study was to compare the effect of resistance training with vascular occlusion with traditional resistance training on muscle function and cardiovascular endurance in young females. for this purpose, 43 female students were randomly divided into three groups: traditional resistance training (trt, 70-80% 1rm, n=14), resistance training with vascular occlusion (rtvo, 20-30% 1rm wi...

The purpose of this study was to examine the acute effect of upper body complex training on power output, as well as to determine the requisite preload intensity and intra-complex recovery interval needed to induce power output increases. Nine amateur-level combat/martial art athletes completed four distinct experimental protocols, which consisted of 5 bench press repetitions at either: 65% of ...

This study examines the acute effects of plyometric exercise on 1 repetition maximum (RM) squat performance in trained male athletes. Twelve men (mean age +/- SD: 20.5 +/- 1.4 years) volunteered to participate in 3 testing sessions separated by at least 6 days of rest. During each testing session the 1RM was assessed on back squat exercise. Before all 3 trials subjects warmed up on a stationary...

The isometric squat has been used to detect changes in kinetic variables as a result of training; however, controversy exists in its application to dynamic multijoint tasks. Thus, the purpose of this study was to further examine the relationship between isometric squat kinetic variables and isoinertial strength measures. Subjects (17 men, 1-repetition maximum [1RM]: 148.2 ± 23.4 kg) performed s...
