운동강도는 운동프로그램 구성의 질적 요소로 운동처방에 대단히 중요하다. HR, RPE, METs, V˙ O₂등으로 나타내며 그 중 나 HR V˙ O₂가장 많이 활용되고 있다(Robert et al, 2000). V˙ O₂max의 검사 방법에는 최대운동부하검사법 과 간접추정법이 있다. 최대운동부하검사법은 최대 운동중의 산소섭취량을 분석하여 정량화하는 방법 으로 정확한 분석을 할 수 있으나 장비의 관리 및 측정에 있어 전문 인력이 필요하며 결과 해석에 있어서도 전문가의 지원이 필요하기 때문에 현장 에서 사용하기가 어렵다(김도윤, 2006). 반면 간접추정법은 피검자의 신체적 특징이나 달 리기 기록, 최대하 운동시 생리적 반응 등을 이용 하여 단시간 내에 V˙ O₂max을 추정하는 방법으로 최대운동부하검사법에 비하여 정확성은 떨어지나 매우 실용적이고 경제적이다(임재형, 2000).
This study aims to develop the estimation formula for V˙ O₂max of the male college students according to the running speed by exercise intensity. The subjects were 17 male college students(19.2±1.6) without any health problems. In the first test, the subjects walked on the treadmills using KSSI protocol until they were all-out to get the maximal oxygen consumption. In addition, Karvonen formula was applied to calculate %HRR by exercise intensity. In the secondary test, the subjects had gradually reached to the exercise intensity for 7 minutes and adjusted the intensity to keep the steady state for about 3 minutes using 02runner to determine the running speed of each subject corresponding to the exercise intensity level of 50%HRR, 60%HRR and 70%HRR. Next, the target exercise intensity was maintained for 12 minutes and the average speed was calculated as checking the speeds every 20 sec. The estimated speeds were put in the estimation formula of metabolic rate of ACSM to calculate V˙ O₂max. After that, the data dealing for analysis of the analyzed the data by using SPSS 10.0 statistics package. The results are explained below. 1. Up to raising speed, HR and V˙ O₂ are also raised so those are quite related between each other(p＜.05). 2. Recurrence formula of speed for HR is speed=(0.08938×HR) - 4.926(R²=0.7552) 3. Recurrence formula of speed for %HRR is speed(m/min)= (0.0765 ×HR) - 2.4947(R²=0.543) 4. The estimation of 50%HRR, 60%HRR, 70%HRR is higher than the survey of them by the comparative result of the estimate and the survey of the degree of exercise for V˙ O₂max. When we synthesize what is commented, the estimate of VO2 max, which is gone wirh the running speed of the degree of exercise, is nevertheless different a little bit between theestimate and the survey, however has a meaning for the high possibility of reproducibility. After a while, if we will raise the member of the experiment considering the high possibility of the relationship and the estimate of the speed for %HRR, the VO2 max estimate would be more precise.
