TRX Training Intensity in Male Adolescent Basketball Players

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.

About this study

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.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Male basketball players aged 15 to 17 years.
  • Active participation in organized basketball training and competition.
  • At least 6 years of regular basketball training experience.
  • Participation in basketball training at least 5 days per week.
  • Written informed consent from a parent or legal guardian and assent from the participant.

Exclusion criteria

  • Serious lower-extremity injury within the previous 6 months.
  • Diagnosed neurological or orthopedic condition limiting training or testing.

  • Incomplete testing records.

Treatment and study plan

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).

Primary outcomes

  1. Agility Performance

    Time frame: 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 outcomes

  1. Dual-task Agility Performance

    Time frame: 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.

  2. Balance Performance

    Time frame: Baseline and immediately after the 8-week intervention

    Balance performance assessed using a stabilometric balance platform. Lower scores indicate better balance control.

  3. Upper-extremity Muscular Endurance

    Time frame: 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.

  4. Rating of Perceived Exertion (RPE)

    Time frame: Baseline and immediately after the 8-week intervention

    Perceived exertion assessed using the Borg CR-10 scale.
