The objective of the study is to compare reaction ability among collegiate school/boys of different body types. Procedure and Methodology: - The 30 collegiate school boys as a subject for this study where select from boring collegiate Sr. Secondary School Batala. The age of the subject were ranged from 15 to 18 years for each somato type i.e. Endomorph, Mesomorph and Ectomorph 10 students were selected randomly who were evaluated for their coordinative abilities on. The method suggested by Health carter subjects were reduced for each somato type. Reaction abilities were selected as a dependent variable somato types, Endomorph, Mesomorph and Ectomorph was considered as an Independent variables. Reaction ability was selected as a dependent variables somato types Endomorph, Mesomorph and Ectomorph was consider as an Independent variable. Stastical Test: To compare reaction ability among the different body types, descriptive statics with the one way analysis of variance. Anova was used the level of significance to check the F-value was set at 0.05. Result: M Relation to reaction ability of the different body types insignificant difference was found. Conclusion: Ectomorphy were having greater mean of reaction ability in comparison to mesomorph & endomorph.
