Indexing fatigue during speed-endurance training

Speed-endurance training (S-E) is a vital component of training in sports such as soccer, tennis, basketball and others, but it can be tricky to evaluate a S-E session on the quantitative level. Heart rate (HR) which is a precise physiological measurement is one way of measuring training intensity, however during recovery from one repetition to(…)

Fatigue biomarkers

Fatigue biomarkers

Fatigue is the enemy in training. It destroys skill work. It eliminates explosiveness. It cuts endurance. Fatigue is our enemy. This is why such an emphasis on training and recovery needs to occur in the preparation of any athlete. Until now, our way of measuring fatigue has been rate of perceived exertion- basically asking from(…)

How long can a muscle work before fatiguing

How long can a muscle work before fatiguing

Can a muscle fatigue after 2-3min work, at sub-maximal loads? Indeed it can.  Muscle fatigue can be predicted by the tension time index (TTdi), a tool developed by Clanton & Grassino in the 1980’s. A tension-time index of 0.15 can predict fatigue when a muscle works indefinitely. The TTdi is the product of normalised force(…)
