The purpose of the study was to examine the effect of core strength training and yogasana practices on selected physical fitness components among female athletes. To achieve the purpose of the study forty-five (N = 45) female athletes, they were selected randomly in Chennai, Tamil Nadu, India as subjects. The age of the subjects ranged from 14 to 19 years. They are divided into three equal groups consists of fifteen subjects each (n = 15) were named experimental group I underwent core strength training and experimental group II underwent yogasana practices and group – III as a control. The period of experimentations is limited to 15 weeks, 4 days a week and 45 to 60 minutes per day with proper warming-up and cooling down regimen. The selected health-related physical fitness components such as muscular strength and muscular endurance were selected as criterion variables and tested. The core strength training and the yogic practices were selected as training protocol. The core strength training will be given based on individuals 1 RM to set the load and the intensity will be set between 75% to 90% The pre-test and post-test means of experimental groups I, II and control group will test for significance by applying the analysis of covariance (ANCOVA). The level of confidence is fixed at 0.05, for significance. In addition to this, Scheffes posthoc test will be employed, when the F-ratio of the adjusted post-test means is significant, to find out the paired mean difference if any among the groups for each variable, separately. Based on the result of the study there was a significant change on health-related physical fitness performance due to core strength training and yogic practice.
