The maximal velocity of shortening in the skeletal muscle is highly correlated with, and thought to be limited by, the rate of adenosine triphosphate (ATP) hydrolysis by myosin (i.e., rate of cross-bridge dissociation) (Barany 1967 ). There is …

Sport climbing, a highly technical activity, places significant stress on the forearm flexors. Extensive research has emphasized the critical role of maximal finger-flexor strength and endurance as reliable predictors of climbing ability (Langer …
In acute hypoxia, the control of heart rate (HR) and blood pressure is challenged by several mechanisms. To sustain the oxygen delivery, the decrease in blood oxygen concentration must be accompanied by an increase in cardiac output (CO), both at …

Resistance training is important for athletes, but also for patients undergoing rehabilitation. Whereas athletes use resistance training to enhance exercise performance based on specific strength and power improvements (Beattie et al. 2014 ; Cormie …
Post-activation potentiation (PAP) is the enhancement of evoked-twitch properties that occurs after a voluntary conditioning contraction (CC) in skeletal muscle (Blazevich & Babault 2019 ). In adults, PAP is greatest in muscles with a higher …
Skeletal muscle plays a crucial role in human metabolism, and increases in muscle mass with resistance training (RT) positively influence health and well-being (Wolfe 2006 ). Skeletal muscle hypertrophy during periods of RT occurs due to the …

Ischemic preconditioning (IPC) appears to improve exercise performance although there is uncertainty about the intensity dependence of this effect. The present study sought to clarify effects of IPC on physiological responses at and below peak …
It is well understood that significant increases in muscular strength following resistance exercise training (RET) can occur in prepubescent youth (Payne et al. 1997 ; Behm et al. 2008 ; Faigenbaum et al. 2009 ; Falk 2015 ). RET is becoming more …

Exercise induces significant changes in various biological responses, including circulation, metabolism, nerve activity, and the immune response. Immune function plays an important role in protecting against infections such as bacteria; however …
In most sports, coaches assess motor, physical and technical skills on a regular basis in the early stages of talent identification in order to optimize athlete development (De Siati et al. 2016 ). However, their assessment is mostly incomplete …
