Competitive swimming is a unique sport which is very difficult to participate when compared to land sports. In competitive swimming, water offer greater density and more resistance which will be difficult for the swimmers to propel forward movement. The purpose of the study was to determine the correlation between height and swimming performance among junior boys swimmers. To achieve the purpose of the study, 25 state level junior male middle distance swimmers were randomly selected from Puducherry in the age group of 14 to 17 years. The stadiometer and 50 mts free style were used to measure height and swimming performance of the swimmers. The Pearson’s Product Moment Correlation was utilized to identify relationship between test variables. It was concluded that there was a significant inverse relationship between height and swimming performance of junior boys swimmers.                 

Key words: Height, Swimming Performance, Pearson’s Product Moment Correlation.
