Abstract
This study explored the effects of partial sleep deprivation (PSD) on Sanda athletes' athletic performance, an area with limited research. Using a randomized crossover controlled trial with 18 male athletes, the PSD group had 4 h of sleep while the NSN group had 8 h. Results showed that after PSD intervention, the RAT time significantly increased compared to the NSN group (P = 0.0311). However, there was no significant change in CMJ (P = 0.2396) or YBT (left leg: P = 0.2767, right leg: P = 0.3225) between the PSD and NSN groups. In the Wingate test, the PSD group exhibited significant reductions in Pmax and Pave at 10s, 30s, and 60s (P＜0.0001), as well as a significant decrease in Prel at 60s (P＜0.0001), with no significant differences in Prel at 10s and 30s. These findings underscore the detrimental impact of limited sleep on anaerobic performance and agility in Sanda athletes, emphasizing the need for proper sleep management for optimal athletic outcomes.
