Effects of partial sleep deprivation after prolonged exercise on metabolic responses and exercise performance on the following day

Abstract

[Purpose] We determined the effect of partial sleep deprivation (PSD) after an exercise session on exercise performance on the following morning. [Methods] Eleven male athletes performed either a normal sleep trial (CON) or a PSD trial. On the first day (day 1), all subjects performed an exercise session consisting of 90 min of running (at 75% ) followed by 100 drop jumps. Maximal strength (MVC) was evaluated before and after exercise. In the CON trial, the sleep duration was 23:00–7:00, while in the PSD trial, the sleep duration was shortened to 40% of the regular sleep duration. On the following morning (day 2), MVC, the metabolic responses during 20 min of running (at 75% ), and time to exhaustion (TTE) at 85% were evaluated. [Results] On day 2, neither the MVC nor during 20 min of running differed significantly between the two trials. However, the respiratory exchange ratio was significantly lower in the PSD trial than in the CON trial ( p = 0.01). Moreover, the TTE was significantly shorter in the PSD trial than in the CON trial ( p = 0.01). [Conclusion] A single night of PSD after an exercise session significantly decreased endurance performance without significantly changing muscle strength or cardiopulmonary response.

Cranial Electrotherapy Stimulation to Improve the Physiology and Psychology Response, Response-Ability, and Sleep Efficiency in Athletes with Poor Sleep Quality

“…Upcoming competitions precipitate lack of sleep or sleep deprivation in athletes [ 7 ]. Anxiety before a competition and overtraining resulted in poor sleep quality [ 8 ]. In this condition, physical and psychological recovery management is required to reduce the risk of poor sleep quality due to overtraining or excessive fatigue and decrease the risk of sports injury [ 9 ].…”
