Trial summary
This randomized controlled trial investigated the effects of elastic band-resisted plyometric training (EBPT) on jump performance in young male soccer players. Thirty-three youth soccer players aged 14-15 years were randomly assigned to one of three groups: elastic band-resisted plyometric training (EBPT, n=10)… Read more about this study

About this study
Official title: Effects of Elastic Band-Resisted Plyometric Training on Jump Performance in Young Male Soccer Players: A Randomized Controlled Trial
This randomized controlled trial investigated the effects of elastic band-resisted plyometric training (EBPT) on jump performance in young male soccer players. Thirty-three youth soccer players aged 14-15 years were randomly assigned to one of three groups: elastic band-resisted plyometric training (EBPT, n=10), traditional plyometric training (PLT, n=11), or control (CON, n=12). Both training groups completed a 6-week intervention consisting of 2 sessions per week with 120-230 foot contacts per session. The primary outcome was countermovement jump without arm swing (CMJ-NS) height. Secondary outcomes included squat jump (SJ), countermovement jump with arm swing (CMJ-AS), single-leg vertical jumps for dominant (SVJ-D) and non-dominant (SVJ-ND) legs, take-off velocity, and peak power. Assessments were conducted at baseline and post-intervention. The study aimed to determine whether adding elastic band resistance to plyometric exercises provides superior training adaptations compared to traditional plyometric training for enhancing lower-limb explosive power in young athletes.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Elastic Band-Resisted Plyometric TrainingBehavioural
Participants performed plyometric exercises (squat jumps, countermovement jumps, drop jumps, and single-leg jumps) with elastic band resistance providing additional load during the concentric phase. Training was conducted twice weekly for 6 weeks, with 120-230 foot contacts per session.
Traditional Plyometric TrainingBehavioural
Participants performed the same plyometric exercises (squat jumps, countermovement jumps, drop jumps, and single-leg jumps) without elastic band resistance. Training was conducted twice weekly for 6 weeks, with 120-230 foot contacts per session.
Regular Soccer Training (No Intervention)Other
Participants continued their routine soccer training program without any additional plyometric exercises during the 6-week study period.

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Countermovement Jump Without Arm Swing (CMJ-NS) Height (time frame: Baseline and 6 weeks (post-intervention)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Jun 2026; AzTrials last refreshed its copy on 7 Nov 2026.
