Outline of Final Research Achievements

Low frequency fatigue (LFF) is characterized by larger depressions in submaximal force than in maximal force. The aim of this study was to examine the effects of thermal pretreatment on LFF in rat fast-twitch muscles. The present results reveal that thermal pretreatment can facilitate recovery of LFF, which is mediated via a quick return of calcium release of sarcoplasmic reticulum to resting levels. These findings suggest that thermal pretreatment exerts beneficial effects, such as the restoration of muscle performance after physical activity.
