This study aimed to determine the effect of plyometric circuit training on cardiorespiratory and power abilities in male volleyball athletes. This study was experimental research with a Quasi-Experimental Design that involved male volleyball athletes from the Yuso Sleman Club as the population. The sample included 20 athletes determined by ordinal pairing, which were then divided into two groups. Using the multistage test, the first group was utilized to measure cardiorespiratory ability (VO 2 max). Meanwhile, the other group used the vertical jump test to measure the power ability. The data analysis applied the t-test to comprehend the data structure in high dimensions because it involved more than one variable. The research analysis showed that the VO 2 max variable in group I increased cardiorespiratory ability by 5.21% or 2.24 ml/kg BW/minute, and group II showed an increase by 2.64 or 1.15 ml/kg BW/minute. The power variable or vertical jump in group I showed 66.20, increased by 0.8 cm or 1.2% to 67.00; group II showed 69.50 cm, increased by 3.60 cm or 5.18% to 73.10 cm. The smash variable in group I showed 27.50 times, increased by 0.20 or 0.73% to 27.70 times, group II showed 27.20 times, increased by 5.8 or 31.32% to 33 times. Based on the results, plyometric circuit training before technical training had a more positive and significant effect on the cardiorespiratory and power of volleyball players, and to improve cardiorespiratory ability and power using plyometric circuit training, it is better to give it after technical training.
