EFFECT OF DAYTIME NAP IN SLEEP DEPRIVATION ON REACTIVE AGILITY

Abstract

The objectives of this research were to study and compare effects of daytime nap and non daytime nap in normal sleep and sleep deprivation on reactive agility. The subjects consisted of a simple random sampling selection of twelve female healthy students from Faculty of Sport Science, Kasetsart University, aged between 18-20 years old. A crossover experimental design was used to compare the reactive agility between the subjects in an intervention period. Subjects were performed four different protocols. Protocol 1 was under normal sleep and daytime nap for 30 minutes; Protocol 2 was under normal sleep and no daytime nap; Protocol 3 was under severe sleep deprivation and daytime nap for 30 minutes, and Protocol 4 was under severe sleep deprivation and no daytime nap. All subjects completed a four - week period of experiment. All subjects were tested for reactive agility after each protocol. Data were expressed as mean ± standard deviation and statistically analyzed by using one way analysis of variance with repeated measure. Statistical significance was set at p < 0.05.
The results of this research showed that mean of reactive agility were significantly differences between four different protocols. This research concluded that Protocol 4 (severe sleep deprivation and no daytime nap) increase reactive agility time when compared with Protocol 1 (normal sleep and daytime nap) and Protocol 2 (normal sleep and no daytime nap). The results from the research suggest that severe sleep deprivation and no daytime nap adversely affect neuromuscular fitness which ultimately resulting in a decline in physical fitness.
