The Responses of Elite Athletes to Exercise: An All-Day, 24-h Integrative View Is Required!

The current research topics in Frontiers of Physiology include “Training intensity, volume and recovery distribution among elite and recreational endura athletes” (Frontiers in Physiology, 2016) and “Wearable Sensor Technology for Monitoring Training Load and Health in the Athletic Population” (Frontiers in Physiology, 2017). As editors of both of these topics, we would like to share some thoughts concerning (a) how they are fundamentally linked and (b) why we believe it is essential to have an all-day, 24-h integrative view to understand elite athletes’ responses to exercise. who train frequently each week schedule their training and off-training for days (i. e. , microcycles, for example, tapering periods, blocks of t) to as long as months (i. e. , macrocycles, for example, periods of preparation with different focuses or training camps) to ensure progressive adaptation and prevent fatigue, boredom, and injury. From this perspective, a fundamental goal is to distribute exercise and off-training effectively over a certain period of time (for example, one or several seasons) to achieve optimal adaptation. , we highlight the importance of an all-day, 24-h integrative perspective on training, emphasizing the fact that conditions outside training significantly modulate adaptation, thereby complicating analysis of the distribution of training intensity.
