The rationale of this study was to appraise the outcome of the twelve weeks of supervised fartlek training programme on selected physiological parameters. For this purpose twelve male athletes from Dr. S. Ramadoss Arts and Science College, Virudhachalam, in the age group of 20 to 22 years took part in the study. The selected subjects were subjected to twelve weeks of farlek training programme. The selected criterion variables namely: maximum oxygen consumption and resting pulse rate were assessed using standard tests and procedures, prior to and subsequent to the training regimen. The pretest and posttest data collected on criterion variables were statistically examined by applying 't' test to find out the significant difference if any. The analysis of data revealed that twelve weeks of farlek training programme significantly improved maximum oxygen consumption and resting pulse rate. These findings propose that the experimental variable has the significant influence in improving the selected criterion variables.

The aim of the present research was to determine the effect of aerobic training on percentage body fat and resting heart rate among obese women. For this purpose twenty (20) female obese samples (age 17-25) were selected. The subjects were given endurance training for only one session in the morning between 6 am and 7 am for three alternate days a week for six weeks. To analyse the collected data,"t" ratio was used at 0.05level of confidence. The results showed that there was a significant decrease in the percentage of body fat but no changes is elicited on resting heart rate. It was concluded that the aerobic training is widely believed to induce changes in the percentage body fat among obese women.
