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.

Outcome Measures

Primary Outcomes (1)

• Agility Performance

  Agility performance assessed using the Illinois Agility Test. Completion time was recorded in seconds using electronic timing gates. Lower values indicate better performance.

  Baseline and immediately after the 8-week intervention

Secondary Outcomes (4)

• Dual-task Agility Performance

  Baseline and immediately after the 8-week intervention

• Balance Performance

  Baseline and immediately after the 8-week intervention

• Upper-extremity Muscular Endurance

  Baseline and immediately after the 8-week intervention

• Rating of Perceived Exertion (RPE)

  Baseline and immediately after the 8-week intervention

Study Arms (3)

LI-TRX

EXPERIMENTAL

Participants performed an 8-week supervised TRX suspension training program at 45-60% heart rate reserve (HRR), three sessions per week, in addition to regular basketball training.

Behavioral: TRX Suspension Training

MI-TRX

EXPERIMENTAL

Participants performed an 8-week supervised TRX suspension training program at 65-75% heart rate reserve (HRR), three sessions per week, in addition to regular basketball training.

Behavioral: TRX Suspension Training

HI-TRX

EXPERIMENTAL

Participants performed an 8-week supervised TRX suspension training program at 80-95% heart rate reserve (HRR), three sessions per week, in addition to regular basketball training.

Behavioral: TRX Suspension Training

Interventions

TRX Suspension Training BEHAVIORAL

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).

Model Details: 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.
