the ability to optimize muscular power output is considered as a basis for successful performance in the most sports. the aim of this study was to investigate changes in dynamic exercise performance following a sequence of preconditioning isometric muscle actions. twelve nonathlete, active female volunteers (age: 16±1 yr, height: 162±6.34 cm, weight: 60±9.21 kg) participated in the present stud...

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...

BACKGROUND The purpose of this study was to explore the relationship between muscle power output at different external resistances and performance of functional tasks. The authors hypothesized that power at 40% skeletal muscle 1 repetition maximum (1RM), in which contraction velocity is high, would explain more of the variability in tasks such as level walking than would peak power or 1RM stren...

PURPOSE/OBJECTIVES To examine peak volume of oxygen consumption (VO2peak) changes after a high- or low-intensity exercise intervention. DESIGN Experimental trial comparing two randomized intervention groups with control. SETTING An exercise clinic at a university in Australia. SAMPLE 87 prostate cancer survivors (aged 47-80 years) and 72 breast cancer survivors (aged 34-76 years). METHO...

The Achilles tendon is one of the strongest and thickest tendons human body. Several studies have reported an immediate decrease in thickness after a single bout resistance training. However, effects blood flow restriction training on not been investigated. purpose this study was to investigate acute different regimens thickness. Fiftytwo participants (27.3 ± 7 years; 177.6 11 cm; 72.2 13.7 kg)...

The purpose of this study was to identify relationships between core stability and various strength and power variables in strength and power athletes. National Collegiate Athletic Association Division I football players (height 184.0 +/- 7.1 cm, weight 100.5 +/- 22.4 kg) completed strength and performance testing before off-season conditioning. Subjects were tested on three strength variables ...
