Myosins generate force and motion by precisely coordinating their mechanical and chemical
cycles, but the nature and timing of this coordination remains controversial. We utilized a …

We evaluated whether task‐dependent, age‐related differences in muscle fatigue
(contraction‐induced decline in normalized power) develop from differences in …

The cardiac cycle is a tightly regulated process wherein the heart generates force to pump
blood to the body during systole and then relaxes during diastole. Disruption of this finely …

Stretch activation (F SA) is the delayed increase in fiber specific tension (force per cross-
sectional area) following a rapid stretch and can improve muscle performance during …

Post-tetanic potentiation of force in fast skeletal muscle is inversely related to muscle or
sarcomere length, diminishing at longer lengths. This relationship has been mainly …

Myosins are a family of motor proteins responsible for various forms of cellular motility,
including muscle contraction and vesicular transport. The most fundamental aspect of …

This study aimed to assess the effects of acute calcium lactate supplementation intake on
the performance and buffering capacity of elite amateur boxing athletes. 8 elite amateur …

A testable molecular proposal for the effects of acidosis on skeletal and cardiac muscle is
presented. It is based on fluorescence studies published in 1974, which provided evidence …

Background and Aim: Increasing active muscle oxygen availability can affect exercise
performance, therefore the oxygen supplementation can be considered as important factor …
