the aim of this study was to compare the effects of substitution of upper and lower body exercises during rest intervals on the quantity of upper body performance and lactate with 75% 1rm (repetition maximum). for this purpose, 15 trained bodybuilders (age 20.9±1.9 years, weight 74.8±5.2 kg and aerobic power 35.48±8.6 ml/kg/min) took part in this study voluntarily. all subjects performed four t...

PURPOSE To determine if the presence of observers affects muscular strength performance in college-age males and females. METHODS Twenty-five women and 24 men participated in the study. Two counter-balanced trials were performed in which participants completed 1-RM tests in bench press and leg press. During one trial, two members of the opposite gender observed the 1-RM tests. During the othe...

The purpose of the present investigation was to determine if significant differences exist among 3 different periodization programs in eliciting changes in strength. Twenty-eight recreationally trained college-aged volunteers (mean +/- SD; 22.29 +/- 3.98) of both genders were tested for bench press, leg press, body fat percentage, chest circumference, and thigh circumference during initial test...

The disabled population varies significantly in regard to physical fitness, what is conditioned by the damage to the locomotor system. Recently there has been an increased emphasis on the role of competitive sport in enhancing health and the quality of life of individuals with disability. One of the sport disciplines of Paralympics is the flat bench press. The bench press is one of the most pop...

Initial strength gains were examined in the context of learning a new skill. Forty female volunteers were randomly assigned to one of four groups: a bench-press training group utilizing heavy loads in its training, a bench-press training group utilizing almost no load, an alternative training group using different exercises, or a control group that did not train. Training period was 6 wk, with ...

The aim of this study was to compare the influence of including dropset exercises in different orders, both in the pre-exhaustion, as in the post-exhaustion method, and to analyze the performance of total work on the bench press and chest flying exercise. Twenty-two male volunteers with a recreational experience in ST were evaluated in six visits in non-consecutive days, at approximately the sa...

The purpose of the present study was to examine the influence of direct supervision on muscular strength, power, and running speed during 12 weeks of resistance training in young rugby league players. Two matched groups of young (16.7 +/- 1.1 years [mean +/- SD]), talented rugby league players completed the same periodized resistance-training program in either a supervised (SUP) (N = 21) or an ...

The purpose of this study was to investigate the importance of training leading to repetition failure in the performance of 2 different tests: 6 repetition maximum (6RM) bench press strength and 40-kg bench throw power in elite junior athletes. Subjects were 26 elite junior male basketball players (n = 12; age = 18.6 +/- 0.3 years; height = 202.0 +/- 11.6 cm; mass = 97.0 +/- 12.9 kg; mean +/- S...

This study examined the acute effects of NaHCO3 ingestion on repetitions to failure and rating of perceived exertion in the back squat and bench press in trained men. Eight resistance-trained men took part in this double-blind, randomized crossover experimental study whereby they ingested NaHCO3 (0.3 g·kg(-1) body mass) or placebo (sodium chloride NaCl: 0.045 g·kg(-1) body mass) solution 60 min...
