This research has 21 male undergraduates students with no experience in weight training conduct 5 weeks Creatine intake and weight training and then examine the effects of the exercise on thigh circumferences, Creatine, Creatinine, Ck in blood. The tests are divided into a group of 9 conducting Creatine intake and weight training (Cr.-G), a Placebo group of 5(Pla.-G), and a Control group of 7(Con.-G) and are prescribed to conduct 1 week exercise adaptive training and 5 weeks main exercise to measure the changes of thigh circumferences, Creatine, Creatinine, Ck in blood before the exercise and after 5 weeks exercise with an analyzer. They are made to take 20g Creatine(5g×4times) in the morning, afternoon, evening and before sleep 4 times a week in the first one week and 10g(5gx2times) before and after the exercise in the 2nd to 5th week with 250ml water, and Pla.-G is made to take starch flour in the same manner. Exercise treatment is conducted according to the weight training program as 70% of 1-RM, 12 sessions, 3 sets from the first till the third week and 75% of 1-RM, 10 sessions, 3 sets from the fourth till the fifth week. The result of this paper can be summed up as below. 1. Thigh circumferences: Although left and right thighs all showed higher increase in Cr.-G than Pla.-G and Con.-G, and also the left and right thighs indicated more significant increase in Cr.-G than Pla.-G(P<.05). However, there was no interaction. 2. Creatine, Creatinine, Ck: Although Creatine showed significant increase between Cr.-G and Pla.-G, and Cr.-G and Con.-G(p<.05), there was no interaction. Creatinine indicated significant increase between Cr.-G and Pla.-G(p<.05), and also there was interaction in Cr. Intake and before and after 5-weeks weight training(p<.05). Ck showed significant reduction between Cr.-G and Pla.-G, and Cr.-G and Con.-G(p<.05), but there was no interaction.
