Subjects were male basketball players (N=16; age=18-22 yrs) from Department of Athletics, National Taiwan College of Physical Education. Subjects were randomly assigned to creatine supplement (double blind; 0.35g/kg wt) and control groups. Anaerobic test was a 5s consecutive vertical jump. Experimental protocol was a combination of two durations (15s and 60s) and two modes of recovery (passive and active recovery; cycling at 40% VO2max). Exercise will consist of 8 bout of cycling at 120% VO2 max interspersed with three minutes recovery periods. Before cycling and following recovery period, 5s anaerobic jumping test will conduct for each bout. Mean power was determine. Independent one-way ANOVA was performed to compare the effect of creatine supplement and control on power output. Repeated measure of 3 way factorial ANOVA was perform to examine the effect of exercise duration, recovery mode, and exercise bout. Pearson moment product correlation coefficient was performed to examine the relationship between supplement dosage of creatine and anaerobic power output. Statistic significant was p<0.05 in the study. In summary, results suggest that creatine supplementation, active recovery, and shortening exercise duration is the crucial factor in maintaining the anaerobic power of lower extremities during intermittent exercise.184281 bytesapplication/pdf肌酸增補; 下肢肌肉; 無氧動力; 間歇運動Creatine supplement; Lower limb muscle; Anaerobic power; Intermitted motionreport
