The purpose of the study was to find out the effect of physical exercises on selected physiological variables such as resting pulse rate and breath holding time among college men hockey players. To achieve this purpose of the study, thirty college men hockey players studying in Voorhees College, Vellore, Sacred Heart College, Vellore Kingston Engineering College, Vellore and Thanthai Periyar Government Institute of Technology, Vellore, Tamilnadu, India were selected as subjects at random.

... e of the subjects were ranged from 18 to 24 years. The selected subjects were divided into two equal groups of fifteen subjects each, such as physical exercises group (Group I) and control group (Group II). The physical exercises group (Group I) underwent their respective training programme for three days per week for twelve weeks. Group II acted as control in which they did not undergo any special training programme apart from their regular day today activities. All the subjects of two groups were tested on selected criterion variables such as resting pulse rate and breath holding time at prior to and immediately after the training programme by using radial pulse and holding the breath for time respectively. The analysis of covariance (ANCOVA) was used to analysis the significant difference, if any in between the groups. The level of significant to test the 'F' ratio obtained by the analysis of covariance was tested at.05 level of confidence, which was considered as an appropriate. The results of the study revealed that there was a significant difference between physical exercises group and control group on selected physiological variables such as resting pulse rate and breath holding time. Significant changes on selected criterion variables were also noticed due to physical exercises.
