본 연구의 목적은 20~21세의 건강한 성인 남자 대학생들을 대상으로 하여 GXT에 의해 직접 측정된 최대산소섭취량(VO₂max)과 MSRT(multistage shuttle run test)를 통해 예측된 VO₂max와의 상호 관련성을 검토하며, 또한 CRF의 검증을 위해 활용될 필드 테스트 방법인 MSRT의 타당성을 제시하고 남자 대학생들의 신체구성 요소들과 VO₂max와의 연관성을 평가하였다. 연구 대상자는 20∼21세 건강한 남자 대학생 총 30명으로 신장, 체중, 체지방률, 체질량지수, VO₂max 그리고 MRST를 측정하였다. 본 연구에서 획득한 모든 자료는 SPSS 20.0 통계프로그램을 이용하여 VO₂max와 MSRT를 통해 예측된 VO₂max의 평균차이는 독립 t-test(Independent t-test)를 실시하였다. GXT와 MSRT의 두 검사 간의 일치성을 검증하기 위해 상관분석(Pearson’s correlation), Bland & Altman plot, LOA(Limit of agreement)분석을 실시하였으며, GXT와 MSRT 간의 차이 평균의 결과를 이용하여 95% 신뢰구간에서 lower limit과 upper limit을 산출하였다. 또한 GXT를 통해 측정된 VO₂max와 MSRT를 통해 측정된 VO₂max와 신체구성과의 상관관계를 알아보기 위해 상관분석을 실시하였으며, 모든 통계처리에 대한 유의수준(α)은 .05로 설정 하였다. 그 결과 성인 남자 대학생들을 대상으로 GXT를 통해 직접적으로 측정된 VO₂max와 MSRT를 통해 예측된 VO₂max 비교 결과 두 검사 간 유의한 차이가 나타나지 않았다. VO₂max와 MSRT를 통해 예측된 VO₂max의 상관분석 결과는 서로 유의한 정적 상관관계가 있는 것으로 나타났다. 또한, Bland & Altman plot과 LOA 분석을 사용한 결과 GXT를 통해 직접 측정된 VO2max와 MSRT를 통해 예측된 VO₂max의 차이 값은 0.2, 95% 신뢰구간의 범위는 -7.4∼7.7으로 나타났다. GXT를 통해 직접 측정된 VO₂max와 신체구성과의 상관분석과 MSRT를 통해 예측된 VO₂max와 신체구성과의 상관분석 결과 모두 유의한 상관관계가 나타나지 않았다. 결론적으로 GXT를 통해 직접적으로 측정된 VO₂max와 MSRT를 통해 예측된 VO₂max는 서로 차이가 없으며, 유의하게 정적인 상관관계가 있는 것으로 나타났다. 또한 GXT를 통해 직접적으로 측정된 VO₂max와 MSRT를 통해 예측된 VO₂max 모두 신체구성과는 유의한 상관관계가 없는 것으로 나타났다. The purpose of the study was to investigate the relation between VO₂max measured by GXT and VO₂max predicted by MSRT for healthy male university students aged 20 and 21. It also suggested the validity of MSRT which is the way of field tests to verify CRF, and evaluated the relation between VO₂max and components of subjects' body composition. The subject was limited to 30 healthy male university students aged 20 and 21 without any medical problems for examination and measurement. The physique and body composition were measured by 신장, 체중, body fat percentage, and body mass index (BMI). These all drew BMI. VO₂max was measured by two ways. In order to measure direct VO₂max, GXT was conducted using a treadmill, and Bruce protocol(Bruce et al., 1973) was used while measuring. MSRT was performed by the way designed by Leger & Lambert(1982), and conducted by using prepared music, CD Player, marking corns, and measuring tape. All data in the study was processed through SPSS 20.0 statistical program. Independent t-test was conducted to verify mean difference between VO₂max measured by GXT and VO₂max predicted by MSRT. Pearson’s correlation, Bland & Altman plot, and LOA(Limit of agreement) were conducted to test conformity between GXT and MSRT. Using the result of mean difference between GXT and MSRT, it yielded lower limit and upper limit in 95% confidence interval. Also, Pearson's correlation was conducted to know correlation between VO₂max measured by GXT, VO₂max measured by MSRT, and body composition. Significance level in all statistical processing was .05. The result from this study was as follows. Comparing VO₂max directly measured by GXT and VO₂max predicted by MSRT for adult male university students, two tests did not show significant differences. The correlation analysis showed that VO₂max directly measured by GXT and VO₂max predicted by MSRT were significantly correlated positively with each other. Also, as the result of using Bland & Altman plot and LOA analysis, difference value between VO₂max directly measured by GXT and VO₂max predicted by MSRT was 0.2, and the range of 95% confidence interval was -7.4 to 7.7. Both the result of correlation analysis between VO₂max directly measured by GXT and body composition and correlation analysis between VO₂max predicted by MSRT and body composition did not show a significant correlation. In conclusion, there was no difference between VO₂max directly measured by GXT and VO₂max predicted by MSRT, and it showed significantly positive correlation. Also, both VO₂max directly measured by GXT and VO₂max predicted by MSRT were not significantly correlated with body composition.

The purpose of this study was to determine heart rate (HR), ratings of perceived exertion (RPE) and oxygen uptake (Vo2) at the anaerobic threshold (AT) in two different exercise modalities, cycle ergometer and treadmil exercise (running). Subjects were 13 women patients with coronary heart disease. All sub-maximal and maximal Vo2 values but Vo2 at the AT for women were significantly higher in treadmill exercise than cycle ergometer. Submaximal and maximal HR values were not significantly different between the two exercise modalities. However, mean RPE values at the AT were significantly higher in cycle ergometer than treadmill exercise. We suggest that appropriate HR values in exercise training should be the same in cycling and treadmill exercise. while RPE values should be 1 or 2 higher in cycling than running.

Taekwondo is one of the most popular sports in korea and new olympic regulation match and a contact sport associated with a large number of injuries. In the present study, taekwondo athletes injuries during training and competitions was investigated via questionnaire. Taekwondo athletes in the universities of Seoul and the metropolitan area in Korea were observed prospectively for one year for acute injuries during training and competitions (n=428). The most time of injuries occurrence are during main exercise and practice. The most injuries occurred by attack or return kick. Contusion(23.4%) and myalgia(23.4%) were the most common type of injuries and the lower extremity was the most commonly injured area(50.6%). The defense type athletes get injured more then the offensive type athletes and they were more injured during return kick and defense than offensive. In men athletes, who has more careers are more get injuries and in women athletes, who has more practice times in everyday are more get injured. The most of ankle(94.6%) and toe(89.6%) injuries were occurred in men athletes. Base on the results of present study, it is suggested that using the protectors and more aggressive attitude are suggestions to reduce injuries.

Kim, E.S., Jang M.J., Lee, M.G., and Jang, W.S. Effects of short-term weight loss on physical fitness level and Wood variables. Exercise Science, 11(2), 335-344, 2002. This study was designed to examine the effects of short-term weight lose on physical fitness level and various blood variables. Eight high school Taekwondo players were asked to lose at least 5% of their body weight in 72 hours. Various variables related physical fitness and blood were measured before and after the weight loss, and the two results were compared. The results were as follows: 1. The mean weight showed significant decrease after a short-term weight loss. 2. The body fat did not show significant change. 3. The lean body mass showed significant decrease. 4. In terms of anaerobic capacity, the peak power, lowest power, and power decrease did not show significant differences. 5. In terms of aerobic capacity, the VO_2max, VCO_2max, and RQ showed significant decrease. 6. Muscular endurance of upper body decreased significantly. 7. The result of the Wood test showed significant difference in total protein, Na^+, P^+ and FFA after the short-term weight loss program. The short-term weight loss resulted in serious decrease in the aerobic capacity of the Taekwondo players. Considering the fact that the Taekwondo players must participate in 6∼8 matches a day, desirable performance might not be impossible without outstanding aerobic ability. It was conclusion that it would be more beneficial for Taekwondo players to develope a long-term weight management program rather than short-term weight loss.
