Effect of Low Medium and High Intensities of Interval Training on Selected Speed and Endurance Parameters

Abstract:

The purpose of the present study was to investigate the effect of low, medium and high intensities of interval training on selected speed and endurance parameters. To achieve this purpose, sixty male subjects were randomly selected as their age ranged from 18 to 22 years. The selected subjects were divided into four groups of fifteen subjects each. Group-I underwent low intensity interval training, group-II underwent medium intensity interval training, group-III underwent high intensity interval training, and group-IV acted as control. All the subjects of the four groups were tested on selected dependent variable namely speed, speed endurance, cardio respiratory endurance and VO2max at before the commencement of training programme (pre-test) and after the respective training for a period of twelve weeks (post-test). The data collected from the four groups prior to and post experimentation on selected dependent variables were statistically analyzed to find out the significant difference if any, by applying the Analysis of Covariance (ANCOVA). Since four groups were involved, whenever the obtained ‘F’ ratio value was found to be significant for adjusted post test means, the Scheffe’s test was applied as post hoc test to determine the paired mean differences, if any. In all the cases the level of confidence was fixed at 0.05 for significance. It was concluded that high intensity interval training was significantly better than medium and low intensity interval training in improving speed, speed endurance and VO2max. In improving cardio respiratory endurance medium intensity interval training was significantly better than high and low intensity interval training.
