the purpose of present study was to examine the effects of caffeine and ephedrine supplement and their combination on maximal strength and mucular endurance in male bodybuilders. 12 male bodybuilders (mean age: 24.41±4.42 years, height: 174.83±3.61 cm and weight: 75.67±8.05 kg) were selected voluntarily. the study design was crossover, in which the subjects were placed in 7 different conditions...

OBJECTIVES To study the effects of eight weeks of supervised, low intensity resistance training (80% of 10 repetition maximum (10RM)) and eight weeks of detraining on muscle strength and blood lipid profiles in healthy, sedentary postmenopausal women. SUBJECTS Fifteen postmenopausal women, aged 49-62 years, took part in the study. Subjects were assigned to either a control (n = 7) or training...

Recent studies indicate that rotator cuff (RC) muscles are recruited in a reciprocal, direction-specific pattern during shoulder flexion and extension exercises. The main purpose of this study was to determine if similar reciprocal RC recruitment occurs during bench press (flexion-like) and row (extension-like) exercises. In addition, shoulder muscle activity was comprehensively compared betwee...

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 study was the comparison of hormonal responses to resistance training with and without blood flow restriction. 14 girl students took part in a crossover design study. the subjects in 3 successive weeks randomly assigned in 3 states: control (con), traditional strength training (tst) and strength training with blood flow restriction (str). exercise was included leg extension, leg ...

researchers and coaches are constantly looking for the most effective ways to enhance athletic performance. the aim of this study was to investigate the response of strength, power and muscle endurance to resistance training with different rest intervals. 16 male volunteers were selected and divided randomly into two groups. group a (n=8, age 22±2.55 yr, height 174.20±6.14 cm, weight 64.20±6.33...

The purpose of this study was to compare the kinematics and muscle activation patterns of regular free-weight bench press (counter movement) with pure concentric lifts in the ascending phase of a successful one repetition maximum (1-RM) attempt in the bench press. Our aim was to evaluate if diminishing potentiation could be the cause of the sticking region. Since diminishing potentiation cannot...

BACKGROUND Dietary supplements containing L-arginine are marketed to improve exercise performance, but the efficacy of such supplements is not clear. Therefore, this study examined the efficacy of acute ingestion of L-arginine alpha-ketoglutarate (AAKG) muscular strength and endurance in resistance trained and untrained men. METHODS Eight resistance trained and eight untrained healthy males i...

The aim of this study was to identify the dry land strength and power tests that can better relate with sprint swimming performance in young competitive swimmers. Twenty-eight (16 boys and 12 girls) young competitive swimmers of national level (12.01 ± 0.56 years-old, Tanner stage 1-2) volunteered to participate in this study. Swimming performance (25 m and 50 m freestyle sprint tests), muscle ...
