Abstract

The purpose of this study was to determine if the type of training (trunk stability exercise versus trunk movement exercise) influenced vertical jump differently. The study also examined two secondary questions: the influence of trunk stability training versus trunk movement strengthening on abdominal muscle hypertrophy and the influence of trunk stability training versus trunk movement strengthening on trunk stability endurance. The study examined the relationship between the main dependent variable (vertical take-off velocity), and the 2 sub analyses (abdominal muscle thickness and trunk stability endurance). Fifty-nine adults from a normal population were randomly assigned to a control group, a stability training group, and a movement training group. After 12 weeks, 46 participants' data were utilized in the statistical analysis of vertical take-off velocities. Testing of vertical jump, leg press strength, abdominal thickness measures, trunk stability strength and trunk stability endurance occurred at week 0 (baseline), after the third and after the twelfth week of training. Using a repeated measures ANCOVA, it was determined that neither the stability nor the movement group changed their vertical take-off velocity after 12 weeks of training. Both the stability and movement groups' trunk stability endurance scores were significantly greater from the control group's scores at week 12 (p
