One night of total sleep deprivation impairs decision-making skills, anaerobic performances, mood states, and perceptual responses in elite Kung-Fu athletes

Abstract

ABSTRACT To explore how one night of total sleep deprivation (TSD) could affect cognitive and physical performances, as well as subjective experiences in 24 elite Kung-Fu athletes (age: 20.2 ± 1.76 years; body mass: 64.67 ± 6.52 kg; height: 1.71 ± 0.04 m). Participants completed, in a randomized counterbalanced order, two tests sessions in the late-afternoon (separated by 72-h recovery) under normal sleep (NS) and TSD conditions. Specific decision-making skills (decision accuracy (DA) and decision time (DT)), various anaerobic-exercises performance (i.e. seated medicine-ball throw (SMBT), horizontal jump (HJ), vertical jump (VJ), isometric back-muscles strength (IBMS), and isometric leg-muscles strength (ILMS)), mood states, and perceptual responses (attention and concentration) were assessed. The TSD was associated with lower values of vigor, and higher values of anxiety, depression, fatigue, anger, confusion, and total mood disturbance, compared to NS. The TSD resulted in lower attention and concentration, compared to NS. Similarly, lower performances of SMBT, HJ, VJ, and ILMS were recorded after TSD compared to NS. For cognitive performances, the TSD resulted in higher DA and lower DT, compared to NS. In summary, one night of TSD elicits negative effects on decision-making and anaerobic performance in Kung-Fu elites through disturbances in mood and attentional capacities.
