The influence of age on performance and muscle activity was studied during computer mouse tasks designed to induce high demands on motor control. Eight young (mean age 25 years) and nine elderly (mean age 63 years) women participated. When the speed

Sufficient tissue oxygenation (TO2) is essential for muscle function in general. However, it is not known to which extent TO2 is influenced during different low-level contractions. The aim was to study the interaction between EMG activity and TO2 dur

The aim of the present study was to investigate the time-course of blood velocity in the forearm during and following isometric handgrip contractions and to reveal a possible temporal relationship between the circulatory response and venous effluent
