肥滿者의 有ㆍ無酸素性 역치에 관한 硏究 = A Study on the VO₂max, Aerobic and Anaerobic Threshold to the Obese

다국어 초록 (Multilingual Abstract)

The purpose of this study is to find out how obesity has influences on VO₂max, aerobic and anaerobic threshold by the tradmill maximal work load exercise. And from the expectation that fatal reason, why obesity has influences on the physical fitness, could be the dead weight, the non-obese were worn a weight jacket of 11kg and the result of it was compared with the one without the weight jacket, and then the influence for obesity defined.
Method
For the subjects this experinent, 10 members of the non-obese and 10 of the obese were chosen from boys high school. The decision of obesity was done by measuring the skinfold thickness of subscpular and triceps and by calculating of % fat. More then 20% of the % fat was considered as obesity.
And the measurement of respiro-cirulatory function was done by treadmill maximal work load test. As the first step, they started to do exercise with 0% of the treadmill slope and 120m/min of the treadmill speed for 2 minutes. After that, they were 1ed to exhaustion by incrementing 1% of the slope and 20m/min of the speed every 2 minutes. The measurement of ventilation was done by Douglas bag method. And for the non-obese, they were worn weight jackets of 11kg witch were considered as % fat weight and the same measurement was implemented.
The measurement of aerobic and anaerobic threshold was done by non-invasive indices. Aerobic threshold (AerT) was decided by the changing point of the first increment of V?? and the changing point of V??ㆍVO₂?? and F??O₂. Anacrobic threshold (AnT) was decided by the changing point of the second increment of V?? and the changing point of V??ㆍVCO₂?? and E??CO₂.
Conclusion
1. For the treadmill running performance, the obese and 11kg loading group were significantly (p<0.001) lower than the non-obese
2. There was no significant difference in VO₂max (ml/kg.min) of the obese for the non-obese. but VO₂max (ml/kg.nin) of the obese were significantly low.
3. when aerobic and anaerobic are appeared, three was no significantly difference in VO₂(ℓ/min), H ·R, V??, %VO₂max but in terms of speed and VO₂/wt (ml/kg.min) the obese were significantly low.
