Abstract

Background

Plyometric involve high intensity eccentric contraction immediately after a powerful concentric contraction. A vertical leap in basketball also involves rapid & repeated muscle contraction & stretching. Various methods have been used to improve the vertical leap in players, but only few studies mention about plyometrics.

Aim

To determine the effect of Plyometric training on vertical jump height in high school basketball players & compare them with their untrained counterparts.

Methods and Materials

144 students were randomly selected & distributed in Group I (Pre-pubertal) & Group II (Pubertal) which was further divided into Group A (trained players) & Group B (untrained students). A gender wise distribution followed this. Plyometric training of 6 weeks was conducted & the vertical jump height pre & post training were recorded & compared.

Results

Vertical jump height improved significantly post Plyometric in Group Bcompared to Group A. Boys showed improvement in Group B, however girls were better in Group A. Correlation of BMI with vertical jump height was negative & significant in Group B.

Conclusion

Plyometric training brought significant change in untrained students. Boys gained more jump height while girls showed significant increase in jump height during pubertal growth spurt. Also, increased BMI reduced jump height.
