According to Blumert, Crum, Ernsting, Volek, Hollander, Haff, and Haff, various studies have been done (including the previous) on how sleep deprivation can effect weightlifting performance, but none of those studies actually modeled a training session that requires performance of a series of high-intensity exercises that are performed for multiple sets and repetitions. For this study, Blumert et al. compared the effects of twenty-four hours of sleep loss on physiological and psychological performance during high-intensity training sessions of national-caliber male collegiate weightlifters. The subjects were tested on three various occasions: finding their one rep max (in snatch, clean and jerk, and front squat) and the experimental conditions …show more content…
All of these are notorious for changing sleeping patterns. What Skein, Duffield, Minett, Snape, and Murphy examined in their research is the effects that overnight sleep deprivation has on recovery (of neuromuscular, physiological, and cognitive function) of competitive rugby athletes. In order to do this, eleven male amateur rugby league players volunteered to participate. The subjects completed two trials: sleep deprivation and control, to determine the neuromuscular, cognitive, and physiological recovery the morning after a rugby match. Each match was a home game against teams of similar competition in order to decrease the variables as much as possible. Also during all matches, distance and speed of movement were recorded using a global positioning system in a customized harness. A post-match analysis was done after each match to count the number of tackles and hits during the match. Also an RPE was obtained 15 minutes after each match. These steps allowed for comparison of external load between matches. The measures included countermovement jump (CMJ) distance, knee extensor maximal voluntary contraction (MVC) and voluntary activation, venous blood kinase and C-reactive protein, perceived muscle soreness, and a word-color recognition-function test. The results of this study …show more content…
jetlag or anxiety) that can cause a reduction in sleep. This study examined the effects of one night sleep deprivation has on reaction time and anaerobic power (both peak and mean anaerobic power). In order to test this, eighteen male physical education students who exercise regularly were asked to keep a regular sleep-wake schedules for at least a three-day period before coming to the laboratory. They were also required to fill out a sleep diary during the course of the experiment and refrain from the consumption of caffeine and talking naps during the day of testing. After baseline measurements were taken, the subjects remained awake the entire night and day while under supervision; during this time they could preoccupy themselves by playing games, reading, or watching television. The Wingate Test was performed for each participant at the same time of the following day. The reaction test consisted of a manual two-choice reaction task. On a screen would appear two empty squares; when either would be filled with red the subject was to move a joystick in the direction of the square. Results for this experiment showed that the mean peak power of subjects exposed to one day of sleep deprivation (8.3±1.6 w.kg -1) was not significantly changed when compared to the baseline (7.9±1.3 w.kg -1). It was also revealed that the mean choice reaction time of subjects exposed to sleep deprivation
