Abstract
The purpose
of present study was to investigate the effects of progressive depth
jumping on vertical jump performance of male athletes. Purposively
selected 80 volunteer male athletes randomly assigned to vertical depth
jump training, horizontal depth jump training , combination of both and
control group. Experimental groups trained twice weekly for 10 weeks,
performing 6 sets of 10 repetitions per session. Dropping height was
progressed from 20 to 40 centimeters according to step method. Vertical
jump was measured before and after 10 weeks. Analysis of covariance was
applied to compare scores. A pair-wise comparison was done by using the
Scheffe’s post-hoc test at 0.05 level of confidence. The results
showed that three training groups improved significantly; vertical
group improved significantly as compared to horizontal group. However,
no significant difference existed between vertical and combination
group; horizontal and combination group. In conclusion, progressive
depth jumping is effective but induces specific adaptations.
