Key result
One night of partial sleep deprivation at the end of the night significantly increased cardiac damage biomarkers in young male athletes, but did not alter cardiovascular or lipid profiles.

Does one night of partial sleep deprivation affect biomarkers of cardiac damage, cardiovascular profiles, and lipid profiles in young male athletes?
Partial sleep deprivation at the end of the night acutely increases cardiac damage biomarkers (myoglobin and creatine phosphokinase) in young athletes, though without affecting lipid or physiological profiles.
May warrant caution on late partial sleep restriction in athletes; extends RCT evidence that acute sleep loss elevates cardiac biomarkers without altering profiles.
Sleep loss is among the most common yet frequently overlooked problems. This disruptive influence is associated with an adverse lipid profile (LP) and consequently results in an increased risk of cardiovascular disease. Furthermore, it has been well established that athletes are increasingly confronted with sleep problems. The aim of this study was to explore the effect of one night of partial sleep deprivation (PSD) on the cardiovascular profile and LP in young, trained athletes. Ten male Taekwondo athletes were randomized for three sleep conditions in a counterbalanced order: (i) following a baseline sleep night (BN), (ii) following PSD at the beginning of the night (PSDBN), and (iii) following PSD at the end of the night (PSDEN). Basal cardiovascular physiological measures were recorded, and blood samples were taken in the fasted state following each sleep session (i.e., in the morning at 07:00 h). The results showed that myoglobin and creatine phosphokinase increased significantly after PSDEN but not after PSDBN. By contrast, no alteration was observed in the LP and physiological parameters following the two types of PSD. In conclusion, these results show that PSDEN increases cardiac damage biomarkers significantly, even though they do not reach clinical significance. Thus, one night of PSD does not affect the physiological responses and biomarkers of LP in Taekwondo athletes.

Mejri et al. (2015) conducted an RCT in Healthy athletes (n=10). Partial sleep deprivation vs. Baseline sleep night was evaluated on Cardiovascular physiological measures, lipid profile, and cardiac damage biomarkers. One night of partial sleep deprivation at the end of the night significantly increased cardiac damage biomarkers in young male athletes, but did not alter cardiovascular or lipid profiles.
