The purpose of this study was to compare the strength performance and aerobic capacity between male non-contact karatedo athletes (N-karate) and male full-contact karatedo athletes (F-karate). There were two groups consisting of seven N-karate (weight : 65 ±3 kg) and seven F-karate (80±6 kg). The control group consisted of eighteen male university students (N-control) weighing 65±3 kg and eighteen male students (F-control) weighing 80±3 kg. All were measured for anthropometric characteristics and all performed physical fitness tests and aerobic capacity test by treadmill running until exhaustion. The body weight, percentage of fat, LBM, and the girth of chest, waist, hip, arm, and thigh on F-karate were significantly larger than those of N-karate. The girth of thigh of N-karate and F-karate were thicker (p<0.05) than those of N-control and F-control, respectively. There were significant differences between F-control and F-karate, and for N-karate and F-karate in the activities of strength performances of grip and back strength, of IRM of the squat, bench press, and dead lift by using barbell. This was not so for N-control and N-karate. However, N-karate showed no difference from F-karate on IRM per kg of body weight with regard to the squat and dead lift. The dead lift in N-karate (2.14±0.13kg/wt) trended to show the higher value than that in F-karate (2.00±0.21kg/wt). For the aerobic capacity, the, endurance times of the control, N-karate, and F-karate were 708±61sec, 899±164sec, and 937±110sec respectively, and there were significant differences between control subjects and karatedo athletes. The VO_2max of N-karate (51.7±3.9ml/kg/min) was the same as the one of F-karate (51.3±3.9 ml/kg/min). These values of karatedo athletes were higher than the one of control (48.0±4.2 ml/kg/min), but not significant statistically. These results suggest that karatedo athletes acquired higher strength performance and aerobic capacity through daily karatedo exercise and that the anthropometric and physical fitness characteristics of full-contact karatedo athletes might be attributed to the amount of weight training.
