Methods: Twenty-six healthy male students were recruited from National Ping-Tung University of Education of physical education, randomly assigned to combined plyometric training group (PT, n=9), plyometric training and creatine group (PT+Cr, n=9), and control group (C, n=8). The PT group were accepted plyometric training and supplemented with maltodextrin, the PT+Cr group were accepted plyometric training and supplemented with creatine 3 times per week every time 20g for six weeks. The PT and PT+Cr groups were trained 3 times per week for six weeks, such as Pogo, Prancing and so on. C group maintain their lifestyle and without any training. Anaerobic capacity (30m sprint test, stand long jump test, 30-s Wingate anaerobic test) and muscle damage (serum CK, LDH, and neutrophils) were test before and after training. The data were analyzed by two-way analysis of variance (group×time) with repeated measures to examine any changes after training. Results: We found 30m sprint test increased significantly in the PT group and the PT+Cr group (4.47±0.22 vs. 4.39±0.23; 4.57±0.15 vs. 4.37±0.17 seconds, p＜.05). Stand long jump test increased significantly in the PT group and the PT+Cr group (2.48±0.17 vs. 2.55±0.17; 2.50±0.12 vs. 2.60±0.11 meters, p＜.05). Mean anaerobic power of 30-s Wingate anaerobic test increased significantly in the PT group and the PT+Cr group (578.11±84.68 vs. 634.67±80.41; 607.00±74.93 vs. 633.11±67.74 watts, p＜.05). But in these three tests, there were not significant difference between the PT and PT+Cr groups (p＞.05). On the variables of muscle damage (serum CK, LDH and neutrophils), there were not significant difference between the PT and PT+Cr groups (p＞.05). We concluded that six weeks plyometric training can improve the anaerobic capacity (30m sprint test, stand long jump test, and mean anaerobic power of 30-s Wingate anaerobic test), but bring out little damage (serum CK, LDH and neutrophils). Combined plyometric training and creatine monohydrate supplement could not any more increase anaerobic capacity and muscle damage additionally.
