This study aimed to examine a wide profile of acute biochemical and neuromuscular responses to strength (STR) and hypertrophy (HYP) resistance exercise (RE). Seven trained men completed an STR workout (4 × 6 repetitions, 85% 1 repetition maximum [1RM], 5-minute rest periods), an HYP workout (4 × 10 repetitions, 70% 1RM, 90-second rest periods), and a control condition (CON) in a randomized cros...

The purpose of this research was to ascertain the relationship between architectures lower body muscles and lunges performance. Thirty recreationally active, untrained males (mean age: 17±1.25 years) were recruited participated in two testing sessions: anthropometrics muscle architecture, one-repetition maximum (RM) test. B-mode ultrasonography used assess thickness, pennation angle, fascicle l...

The response of calf-muscle strength, resting blood flow, and postocclusive blood flow (PObf) were investigated after 4 wk of low-load resistance training (LLRT) with and without blood-flow restriction in a matched-leg design. Ten untrained older individuals age 62-73 yr performed unilateral plantar-flexion LLRT at 25% 1-repetition maximum (1RM). One limb was trained with normal blood flow and ...

Exercise or Swiss balls are increasingly being used with conventional resistance exercises. There is little evidence supporting the efficacy of this approach compared to traditional resistance training on a stable surface. Previous studies have shown that force output may be reduced with no change in muscle electromyography (EMG) activity while others have shown increased muscle EMG activity wh...

The purpose of this study was to determine test-retest reliability for peak barbell velocity (Vpeak) during the bench press (BP) and bench press throw (BPT) exercises for loads corresponding to 20-70% of one-repetition maximum (1RM). Thirty physically active collegiate men conducted four evaluations after a preliminary BP 1RM determination (1RM·bw-1 = 1.02 ± 0.16 kg·kg-1). In counterbalanced or...

Purpose: A proper warm-up method can be used as a strategy to improve performance of athletes in various sport fields. The aim of present study was to compare the effect of two traditional and post-activation potentiation warm-up methods on electromyographic variables of lower extremity muscles during squat jump. Methods: Fourteen trained male athletes were randomly performed three different p...

This study aimed to analyze acute changes in the muscle mechanical properties of triceps brachii long head after bench press exercise performed at different external loads and with intensities effort along power performance. Ten resistance-trained males (age: 27.7 ± 3.7 yr, body mass: 90.1 17.1 kg, height: 184 4 cm; experience resistance training: 5.8 2.6 relative one-repetition maximum (1RM) p...
