Elastic Band-Resisted Plyometric Training in Young Soccer Players

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.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
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 120-230 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 120-230 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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Countermovement Jump Without Arm Swing (CMJ-NS) Height
Time Frame: Baseline and 6 weeks (post-intervention)
Vertical jump height measured during countermovement jump without arm swing, assessed using a portable force platform.
Baseline and 6 weeks (post-intervention)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
