Effects of training volume on sleep, psychological, and selected physiological profiles of elite female swimmers.
Excessive training is reported to cause sleep disturbances and mood changes.
For each study phase, polysomnographic recordings, body composition, psychological parameters, and swimming performance measures were obtained. A daily training log and sleep diary were maintained for the entire study period. The number of movements during sleep was significantly higher at the higher training volumes, suggesting some sleep disruption. Sleep and sleep variables are associated with training workloads and reductions in those loads. Return to Table of Contents for this issue .
