Abstract

This study investigated the impact of hypoxic training on sleep quality and neuromuscular performance in 21 male national netball athletes aged 18-41. Subjects were randomly assigned into a hypoxic training group (n=11) or a non-hypoxic control group (n=10). Sleep quality was assessed using actigraphy. Neuromuscular performance was evaluated through countermovement jump test on a force plate. Results showed no significant differences in overall sleep quality between the groups both pre- and post-test. However, the hypoxic group exhibited a substantial mean decrease in sleep efficiency of 12.2% post-training, suggesting hypoxic exposure may negatively impact sleep. The hypoxic group also demonstrated higher average and peak relative power production during jumps compared to controls. Perceived exertion was significantly greater in the hypoxic group during training sessions. During training, the hypoxic group reported higher perceived exertion (RPE) and significantly lower average and peak power outputs compared to the non-hypoxic group, indicating greater fatigue under hypoxic conditions. In conclusion, while hypoxic training did not significantly alter overall sleep quality, it may reduce sleep efficiency and increase perceived effort. Hypoxic exposure appears to enhance neuromuscular performance parameters like power output in male netball athletes. Coaches should consider the potential effects of the training environment on sleep, fatigue and performance when designing training programs
