The purpose of the study was designed to examine the effect of aerobic circuit training on elastic power and explosive power in terms of vertical of university men students.  For the purpose of the study, thirty men students from the Department of Physical Education, Annamalai University were selected as subjects. They were divided into two equal groups. each group consisted of the fifteen subjects. Group I underwent aerobic circuit training for three days per week for twelve weeks. Group II acted as control who did not undergo any special training programme apart from their regular physical education programme. The following variables namely elastic power and explosive power in terms of vertical were selected as criterion variables. All the subjects of two groups were tested on selected dependent variables namely elastic power and explosive power in terms of vertical at prior to and immediately after the training programme by using bunny hops and vertical jump respectively. The analysis of covariance was used to analyze the significant difference, if any among the groups. The .05 level of confidence was fixed as the level of significance to test the ‘F’ ratio obtained by the analysis of covariance, which was considered as an appropriate. The results of the study indicated that there was a significant difference between the adjusted post-test means of aerobic circuit training group and control group on elastic power and explosive power in terms of vertical.
