Comparison between depth jump and countermovement jump for increasing vertical jump heightin male Badminton players

Many controversies exist between effects of jump training programs. Hence the objective of this study was to study the effectiveness of jump training in male Badminton players and to compare depth jump training and counter movement jump training for increasing vertical jump height.

30 Male Badminton players undergoing training, aged 20–25 years and playing Badminton for at least 1 year were selected by simple random sampling method. Amateur and professional badminton players, those with history of musculoskeletal disorders within 6 months, cardiovascular disorders, neurological disorders and body weight more than 220 lbs were excluded from the study. The players were randomly divided into two groups: countermovement jump group and depth jump group. Their static vertical jump was assessed and they were given a separate training program for 6 weeks (two sessions/week). Outcome was assessed as improvement in vertical jump score at the end of 6 weeks. Analysis was done using paired and unpaired t test.

The mean pre training vertical jump score in the Counter movement jump group was 38.5 which increased to 39.1 at 3 weeks of training and further increased to 39.7 at 6 weeks of training. The mean pre training vertical jump score in the depth jump group was 39.6 which increased to 40.4 at 3 weeks of training and further increased to 41.4 at 6 weeks of training. There was a significant increase in the vertical jump height post-training in both the groups at 3 and 6 weeks (<0.01). The increase in depth jump group was significantly more than the increase in counter-movement jump group at 6 weeks (<0.01).

Jump training program is effective to increase vertical jump height in male Badminton players. However, depth jump training program is significantly more effective for improving vertical jump height as compared to countermovement jump training program.
