한국 국가대표 복싱선수들의 체급별 신체조성 및 전문체력 프로파일

PURPOSE: The purpose of this study was to analyze the differences of body composition and specific physical fitness by weight category, and examine the reciprocal relationship in the national amateur male boxers. METHODS: The national amateur boxers were classified into light weight category (LWC, n=14), middle weight category (MWC, n=15), and heavy weight category (HWC, n=14). The subjects were measured for body composition and specific physical fitness: body fat, BMI, maximal strength (bench press, squat), anaerobic power (lower/upper body mean and peak power, power drop rate), isokinetic strength (knee and trunk), and cardiovascular endurance (AT, HRmax, VO2max). One-way repeated ANOVA was used to evaluate the differences between three groups and pearson`s correlation analysis was applied to examine the relationship between body composition and specific physical fitness. RESULTS: The results of this study indicated that the HWC showed significantly higher body fat and BMI compared to the LWC and MWC (p<.05). The LWC was significantly lower in the peak power of the upper body compare with the MWC and HWC (p<.05). The HWC was significantly higher in the power drop rate compare with the LWC (p<.05). On the other hand, the was significantly lower in the isokinetic trunk flexion, HRmax, and VO2max compare with the LWC and MWC (p<.05) while the LWC showed the best level in HRmax and VO2max. There were significantly reciprocal relationships between body fat, BMI and specific physical fitness factors (p<.05). In particular, body fat, squat, mean and peak power showed significant relationships with many variables. CONCLUSIONS: The LWC and MWC of the national amateur boxers showed comparatively greater level of VO2max. However, the power endurance of the upper body and the peak power of the body have been estimated to be somewhat low. The HWC needs to maintain an ideal body fat, and pay attention to the strengthening of the core flexor and cardiovascular endurance. Successful preparations may be accomplished for the Rio Olympics through the efficient strategy and specific physical training based on the results of the study
