Circuit Training with Interval Ratio at a Different Altitude Enhanced the Maxymum Oxygen Volume Basket Ball Athletes

The purposes of this study was analyzed 1) Effect of circuit training with interval ratio to increase in VO2 Max 2) Effect of elevation of exercise site to increase VO2 Max.3) The effect of interaction between the circuit training with the interval ratio and the height of the training site on the increase in VO2 Max. The research method used is experimental method. Population in this research was atlet Regency of Bangli and Buleleng Regency. The sample in this study was a Basketball athlete. Data collection techniques using MFT. Technique of data analysis using Analysis of Two Path Variant. Results of data analysis at significance level = 0.05 as follows (1) VO2 Max athletes trained with circuit training with 1 1 interval ratio (mean = 42.34) better than athletes trained by circuit training with ratio interval 1 3 (mean = 39, 13) obtained statistical value 10, 395 with significance 0, 002. (2) VO2 High-trained maxs (mean = 42.12) better than low-trained athletes (mean = 39, 30) obtained statistical value of 7, 784 with significance 0.007. (3) There is interaction influence between circuit training with interval ratio with altitude of exercise place obtained statistical value 49, 785 with significance 0, 000. The conclusion of the results of this study is that the hypothesis has been proved to be true, that circuit training with a 1 1 interval ratio is better than circuit training with a 1 3 interval ratio, and upland exercise is better than lowland exercise and interaction effects between the circuit training with the interval ratio and the height of the training ground. Circuit training with 11 interval ratio in the highlands is more appropriate.
