Recovery Interval during Physical Training Depends on both Neural and Energetic Constraints

Physical training and sport conditioning depends on the correct conjugation of stimulus-load, resting and nutrition. Given that load and nutrition are adequate for training goals, rest handling is crucial for training control and posterior adaptation. Adequate resting between exercises, sets or workouts gives the direction for muscle/ body adaptation, allowing not only to achieve training goals but also to avoid situations of extreme fatigue whose deficient copping can induce non-physiological overreaching or pathological overtraining [1]. Thus, analysing optimal resting intervals is of surmount importance in the training process of different activities as high level sport training and rehabilitation.
