Brief summary
This randomized interventional study aims to compare the effects of low-, moderate-, and high-intensity TRX suspension training on physical performance in male adolescent basketball players. Forty-two athletes aged 15 to 17 years are assigned to one of three TRX training intensity groups and complete an 8-week supervised training program in addition to their regular basketball practice. Outcomes are assessed before and after the intervention and include agility, dual-task agility, balance, upper-extremity muscular endurance, and rating of perceived exertion (RPE). The study seeks to determine whether different TRX training intensities produce distinct adaptations in these performance outcomes and to provide evidence for optimizing suspension-training prescription in youth basketball players.
Detailed description
Basketball performance depends on agility, balance, neuromuscular coordination, and the ability to perform motor tasks under cognitive demands. TRX suspension training has become increasingly popular in athletic conditioning because it challenges trunk stability, body control, and functional movement patterns. However, limited evidence is available regarding whether different TRX training intensities produce distinct adaptations in adolescent basketball players. This randomized, three-arm interventional study compares the effects of low-, moderate-, and high-intensity TRX suspension training performed over an 8-week period in male adolescent basketball players. Training is conducted three times per week in addition to regular basketball practice. Internal training intensity is prescribed using heart-rate reserve (HRR) zones and monitored throughout the intervention. The study evaluates changes in agility, dual-task agility, balance, upper-extremity muscular endurance, and perceived exertion. The primary objective is to determine whether prescribing different TRX training intensities results in different neuromuscular and performance adaptations in adolescent basketball players. The findings are expected to contribute to evidence-based recommendations for the prescription of suspension training in youth basketball conditioning programs.
Interventions
BEHAVIORALTRX Suspension Training
Participants completed an 8-week supervised TRX suspension training program performed three times per week in addition to their regular basketball training. All groups completed the same exercises, session frequency, session duration, training volume, and supervision. The intervention included TRX Side Bend, Knee Pull, T-Jump, Squat Jump, Mountain Climber, Superman, Sumo Squat Jump, Single-Leg Squat, Side Squat, and Hamstring Curl. The only difference between groups was the prescribed internal training intensity based on heart rate reserve (HRR): 45-60% (LI-TRX), 65-75% (MI-TRX), or 80-95% (HI-TRX).

Intervention model description
Participants were randomly assigned to one of three parallel intervention groups receiving low-, moderate-, or high-intensity TRX suspension training. Each group completed an identical 8-week training program with the same exercises, frequency, session duration, and supervision. The only planned difference between groups was the prescribed internal training intensity based on heart rate reserve (HRR). Outcomes were assessed before and after the intervention.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Agility Performance | Baseline and immediately after the 8-week intervention | Agility performance assessed using the Illinois Agility Test. Completion time was recorded in seconds using electronic timing gates. Lower values indicate better performance. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Dual-task Agility Performance | Baseline and immediately after the 8-week intervention | Dual-task agility assessed as completion time during the Illinois Agility Test performed concurrently with a verbal cognitive task. Lower values indicate better performance. |
| Balance Performance | Baseline and immediately after the 8-week intervention | Balance performance assessed using a stabilometric balance platform. Lower scores indicate better balance control. |
| Upper-extremity Muscular Endurance | Baseline and immediately after the 8-week intervention | Upper-extremity muscular endurance assessed using the 30-second push-up test. Higher values indicate better performance. |
| Rating of Perceived Exertion (RPE) | Baseline and immediately after the 8-week intervention | Perceived exertion assessed using the Borg CR-10 scale. |
