The purpose of the study was find out the influences of swiss ball training on core strength and shoulder strength among school boys. To achieve the purpose of this study, 30 school boys were randomly selected as subjects from Kamarajar Higher Secondary School, Pettai, Tirunelveli, Tamil Nadu, India. Their age ranged from 16 to 18 years. The selected participants were randomly divided into two groups such as group 'A' swiss ball training group (n=15) and group 'B' acted as control group (n=15). Group 'A' underwent swiss ball training for three alternative days per week and each session lasted for an hour for twelve weeks. Control group was not exposed to any specific training but they were participated in regular activities. The core strength was assessed by plank test (seconds) and shoulder strength was assessed by push-ups test (numbers) were selected as variables. The pre and post tests data were collected on selected criterion variables prior to and immediately after the training program. The pre and post-test scores were statistically examined by the dependent 't' test and analysis of co-variance (ANCOVA). The level of significant was fixed at 0.05 level. It was concluded that the swiss ball training group had shown significantly improved in core strength and shoulder strength. However the control group had not shown any significant improvement on core strength and shoulder strength.

The purpose of the study was to find out the influence of plyo push-up exercises on shoulder strength and explosive power among sports participants. To achieve the purpose of the study thirty sports participants were selected randomly as subjects from Kamaraj Higher Secondary School, Pettai, Tirunelveli District, Tamilnadu, India and their age were ranged from 15 to 17 years. The subjects divided into two groups in equal numbers (N=15). Group-I underwent plyo push-up exercises and Group-II acted as control group who did not attended any special training other than their daily school schedule curriculum. The duration of the training period was restricted into six weeks. The selected criterion variables shoulder strength and explosive power were assessed by Push-Up Test and Medicine Ball Throw (4kg) test respectively. The collected data from the two groups prior to and after the experimental treatments on shoulder strength and explosive power were statistically analyzed by using the statistical technique of dependent't' test and analysis of covariance (ANCOVA). In all the cases level of confidence was fixed at 0.05. The result of the study indicated that plyo push up exercises group had shown significantly improved in shoulder strength and explosive power among sports participants. However the control group did not shown any significant improvement on selected variables such as shoulder strength and explosive power.
