1. Effect of alternate high and low intensity training and progressive training on physical and physiological variables among boys.

The aim of this study was to finding out the Effects of Alternate High And Low Intensity Training And Progressive on Training on Physical And Physiological Variables Among Boys. The purpose of the study was to explore on the effect of alternate high and low intensity training and progressive training on physical and physiological variables among boys. To achieve this purpose ninety students (N=90) were selected randomly as subjects from, Guntur District, Andhra Pradesh, India. Their age is between 16 and 18 years. The subjects were randomly divided into three groups and each group contained 30 subjects Group–I (n=30) underwent alternate high and low intensity training, group–II (n=30) underwent progressive training and group–III acted as control. The subjects were free to withdraw their consent in case they feel any discomfort during experiment and testing period. The pretest and post–test means of experimental group I, II and the control group were tested for significance by applying analysis of variance (ANOVA) after eliminating the influence of pre-test, the adjusted post-test means of experimental groups and control group were tested for significance by using analysis of co variance (ANCOVA). The level of confidence was fixed at 0.05 for significance In addition to this Schaffer’s post-hoc test was employed, when the ‘F’ ratio of adjusted post-test means was significant to find out the paired mean difference, if any among the groups of each variable separately.
