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 240-460 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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Elastic Band-Resisted Plyometric Training (EBPT)
Participants performed plyometric exercises with elastic band resistance for 6 weeks, 2 sessions per week
Behavioral: Elastic Band-Resisted Plyometric Training
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 240-460 foot contacts per session.
Active Comparator: Traditional Plyometric Training (PLT)
Participants performed traditional plyometric exercises without elastic band resistance for 6 weeks, 2 sessions per week,
Behavioral: Traditional Plyometric Training
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 240-460 foot contacts per session.
Active Comparator: Control (CON)
Participants continued their regular soccer training without any additional plyometric exercises during the 6-week intervention period.
Other: Regular Soccer Training (No Intervention)
Participants continued their routine soccer training program without any additional plyometric exercises during the 6-week study period.
