The purpose of this study was purposive selected from the navodaya vidhyalaya, Indore district one hundred and fifty subjects belonging to different groups (Experimental and control) fifty each, has been presented in this chapter. The subjects were divided randomly into three equal groups consisting of fifty subjects, namely meditation (experimental group one), Aerobics (experimental group two) and finally the control group which followed its usually routine practice. The data on selected criterion measures for all the three groups were collected under like conditions.

Objectives: The main objective of the study was to see comparative effect of aerobics activities and meditation exercise on self-concept and level of aspiration, the objective of the study was to see the effect of aerobics on self-concepts. The objective was to see the effect of aerobics on level of aspiration, the objective of the study was to see the effect of meditation on self-concept., the objective of the study was to see the effect of meditation on level of aspiration.

Statistical procedure: Further analysis of covariance was applied with regard to two experimental groups and a control group and the pre test and post test randomized group design and control group were assigned at random. The difference between initial means of the group at pre test was taken into accounting during analysis of post-test, difference between the means by the process of application of ANCOVA, where the final means were tested for significance at 0.05 levels.

Methodology: The details about the selection of subjects, selection of variables, collection of data, experimental design, procedure, duration of yoga and aerobics exercise, administration of test and statistical procedure in analyzing the data has been mentioned in this chapter. One hundred fifty male schools going (Navodaya Vidhyalaya class IX of Indore cluster) were selected for the study. The subjects belong to different schools of Navodaya Vidhyalaya, Indore cluster. Further there group i.e. two experimental groups and one control group (each of 50 students) were randomly formed from the selected subjects. After going through the literature and discussion with the expert following psychological and physical variables were preferred for the study.

Psychological variables Self-concept and level of Aspiration

Physical variables 1. Yoga and Aerobics

Criterion Measures: The Criterion Measures chosen for testing hypothesis were the scores obtained through the various testing procedures stated below on the physical and psychological variables. Thus it may be concluded that N.T.R does not improve in control group. All the treatment is effective in improving the performance of N.T.R score of subjects. In order to find out which treatment is more effective, Pair wise comparison analysis on adjusted means of post data was carried out. Result clearly shows that no significant differences were found between N.T.R of meditation group and aerobic group. Significant differences were found among meditation and control group. Significant difference were found among aerobic and control group. Form the findings it is concluded that meditation and aerobic both are effective in improving the N.T.R score of subjects.
