Elite level athletes have tremendous amounts of stress and pressure to endure, for the sake of performing at peak levels time after time. Sleep loss, might be caused by a busy schedule, travelling, etc. leads to increased anxiety and fatigue which in turn decreases performance (Souissi et al., 2013). According to Fullagar et al., (2015) sleep plays a crucial part to normal cognitive and physiological functioning and homeostasis of human beings. Sleep deprivation can alter this homeostasis process and decrease alertness. Sleep deprivation can be categorized into partial and total sleep deprivation. A sleep deprived person will have trouble staying awake during their regular circadian rhythm. In total sleep deprivation, the person gets no sleep at all. This is more likely to occur in acute situations such as staying awake for 24 hours. In partial sleep deprivation, the persons sleep is disrupted or reduced due to but not limited to, stimulants, sleep disorders or lifestyle (Weinger & Ancoli-Is
rael, 2002). In an article by Souissi and colleagues, (2013), they looked at judo athletes and the effects of partial SD (sleep deprivation) on maximal strength and anerobic power. Moreover, in two different studies, one done by Mamiya, Kubota, Morii, & Goto, (2016), looked at the effects of partial SD on muscular strength and physiological responses of seven male athletes. The second article by Coyle, Casner, & Kornguth, (2018) looks at the influences of specifically 36 hours of SD on physical and cognitive performance. For this review, the focus will be only on the physical performances. Similarly, in an article by Taheri, & Arabameri, (2012) looked at 18 randomly selected participants who were told to stay awake throughout the day and night. They were then to measure the effects of mean and peak power and anerobic performance. The similarity of these articles focusses on SD, either partial or total, and its effect/influence on power and anerobic performance in the means of a Wingate test.
