Stretching to enhance jumping ability in athletes
Official title: Flexibility Training (Stretching) to Improve Jumping Performance
Run by University of Saskatchewan · NCT06944652 · Data updated 2026-11-12
This study is testing if an 8-week stretching program for the calf muscles can help young athletes jump higher compared to a shoulder stretching program.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adolescent athletes currently involved in a sport training program.
✕Probably not a fit
Patients with current or past injuries affecting jumping performance or the ability to stretch the plantar flexors or shoulder joint may not benefit from this study.

What this trial studies
This study compares the effects of an 8-week plantar flexor stretching program against a shoulder stretching program on vertical jump performance in adolescent athletes. The hypothesis is that increased flexibility, particularly in the plantar flexors, may lead to improved jumping ability by allowing for greater force development during the jump. Participants will be stratified by sex and maturity status and randomly assigned to one of the two stretching groups. Vertical jump and landing performance will be assessed before and after the intervention to measure the outcomes.
Why it matters
Potential benefit: If successful, this study could lead to improved training methods for enhancing athletic performance in jumping sports.
How similar studies have gone: While the specific approach of comparing plantar flexor and shoulder stretching is novel, similar studies have shown that flexibility training can positively impact athletic performance.
