Comparing the Effectiveness of a Short-Term Vertical Jump vs. Weightlifting Program on Athletic Power Development

Area of Science:

• Sports Science
• Exercise Physiology
• Biomechanics

Background:

• Developing neuromuscular power and its application to sport-specific actions is crucial for athletes in team-based sports.
• Short-term training interventions are often necessary due to limited preseason periods.

Purpose of the Study:

• To compare the effectiveness of a 6-week Olympic-style weightlifting (WL) program versus a vertical jump (VJ) program on athletic power development.
• To assess changes in center of mass (COM) power and sport-specific performance metrics following short-term training.

Main Methods:

• Twenty-six recreationally active men (18-30 years) were randomly assigned to either a WL or VJ training group.
• Training interventions lasted for 6 weeks.
• Performance was assessed pre- and post-training using countermovement jump (CMJ), squat jump (SJ), depth jump (DJ), 20-m sprint, and 5-0-5 agility tests.

Main Results:

• Both WL and VJ groups showed significant improvements in all vertical jump tests, sprint times (0-5m and 0-20m), and agility test times (p < 0.01).
• The WL group exhibited greater increases in peak power output during CMJ and SJ compared to the VJ group.
• No significant differences in performance improvements were found between the WL and VJ groups across all measured outcome variables.

Conclusions:

• Both Olympic-style weightlifting and vertical jump training are effective for enhancing athletic power and improving performance in team-sport specific tasks.
• The choice between WL or VJ training may not significantly impact overall performance gains in short-term interventions.
• Athletes can benefit from either training modality to improve power-related performance, even with limited training time.
