Does partial sleep deprivation alter intermittent aerobic performance in Taekwondo players?
Does partial sleep deprivation alter intermittent aerobic performance in Taekwondo players?
Partial sleep deprivation at the beginning or end of the night does not significantly impair intermittent aerobic performance in Taekwondo players the following morning.
Partial sleep deprivation may not impair next-day intermittent performance in Taekwondo players; leaves open generalizability to other athletes or protocols.
The purpose of this study was to evaluate the effects of two types of partial sleep deprivation (PSD) on Taekwondo players’ intermittent aerobic performance. Ten male Taekwondo players performed the Yo-Yo Intermittent Recovery Test Level 1 (YYIRTL1) in three conditions in a counterbalanced order, allowing a recovery period ⩾36 h in between them: (A) following a full night of habitual sleep known as a reference normal sleep night (RN), (B) following PSD in the beginning of the night (PSDB), and (C) following partial sleep deprivation at the end of the night (PSDE). No significant difference was observed between the total distance covered inYYIRTL1 (TDYYIRTL1), heart rate peak (HRpeak), plasma lactate concentration, and rating of perceived exertion scale values recorded during YYIRTL1 after (RN), and the two types of PSD (PSDB and PSDE). In summary, the present study indicates that PSDB or PSDE does not alter the intermittent aerobic performance of Taekwondo players in the morning of the following day.
