The aim of the present study was to evaluate the effect of Swiss ball and crunches on muscular strength and abdominal strength. For the purpose of the study 30 sedentary male students from Pondicherry University were randomly selected and their age ranged between 19-22 years. Subjects were asked to assemble in the multipurpose hall in the morning hours and were given training. The subjects were hostel students and their food patterns were similar. Their life style and living condition were not taken into consideration. They were divided into three groups A, B and C with 10 subjects in each group. Group A was kept under control group (CG), group B was treated with Swiss ball training (SBTG) and group C were given crunches exercise (CEG). The subjects of group B and C underwent training for twelve weeks with the duration of 45 minutes. The training was started at 6.30 am and it was given for 6 days per week. The pre test and post test on muscular strength and abdominal strength was measured using push up test and bent knee sit-ups. The data was statistically analysed by using ANCOVA to find out the significant difference among the three groups. The finding of the study revealed that there was a beneficial effect on muscular strength and abdominal strength for both the experimental groups when compared to the control group. The training was more effective for the group doing CEG than the group B (SBTG) group.
