Drop-height plyometric training for soccer players
Official title: Effects of Low, Moderate and High Drop Height Plyometric Training on Lower Limb Explosive Strength, Anaerobic Power and Change of Direction Performance in Competitive Soccer Players: A Randomized Controlled Trial
Run by Riphah International University · NCT07484425 · Data updated 2026-11-12
This study will test whether low (30 cm), moderate (45 cm), or high (60 cm) drop-height plyometric training helps competitive soccer players aged 18–30 improve explosive strength, anaerobic power, and change-of-direction performance.

Is this trial a fit for you?
✓Likely a good fit
Ideal participants are healthy male or female competitive soccer players aged 18–30 with at least one year of regular training and currently active more than three days per week.
✕Probably not a fit
Players with recent lower-limb injury, contraindications to high-impact exercise, or who have performed structured plyometric training in the past three months may not receive benefit from the interventions tested.

What this trial studies
This randomized controlled trial will enroll 56 competitive soccer players aged 18–30 who train at least three times per week. Participants will be randomly assigned by sealed envelopes to one of three supervised plyometric programs differing only in drop-jump height (30 cm, 45 cm, or 60 cm) and will train three times per week for six weeks. Outcomes measured at baseline and post-intervention include Vertical Jump Test, Running-Based Anaerobic Sprint Test (RAST), and the T-test for agility, with statistical comparisons performed in SPSS v25. The protocol excludes players with recent lower-limb injury, musculoskeletal or neurological disorders, contraindications to high-impact training, or recent structured plyometric training, and all sessions take place at the Punjab Sports Board in Lahore.
Why it matters
Potential benefit: If successful, this could identify the most effective drop height to safely improve jumping, sprinting, and agility in competitive soccer players.
How similar studies have gone: Previous plyometric programs have reliably improved jump height, sprint performance, and change-of-direction in youth and adolescent soccer players, but randomized head-to-head comparisons of different drop heights are limited.
