The purpose of this study was to investigate how a short-term oral administration of creatine could influence on body composition and isokinetic muscle strength. A total of 14 collegiate student was divided equally into two groups; creatine-treated group (CG) and placebo group (PG). The CG consumed creatine for 6 days (4 x 5g/day). The effect of a short-term creatine administration with a high intensity weight training was examined, and it could be concluded as; 1. After the short-term creatine administration with a high intensity weight training, lean body mass was increased and body fat mass was decreased. However, no statistical significance was found. The total body water was increased in CG. 2. The short-term creatine administration increased lower back muscle strength and grip strength in both groups. However, muscle function measured as isokinetic contraction has changed positively. Based on the results, changes of body composition may not be efficient by a short-term creatine administration. However, it is possible that a longer administration may change body composition. In general, increased muscle strength was similar in both groups. Thus, the effect of creatine treatment was not conclusive. But, muscle function measured by using an isokinetic machine showed an efficiency of the treatment. The results support a positive effect of creatine. Therefore, creatine administration may not be useful for hypertrophy and muscle strength elevation for general population. However, for those who perform in elite level such as weight lifters or sprinters, the treatment may be highly efficient.
