Brief Summary

This field-based exploratory pre-post study examined the effects of a six-week horizontally oriented plyometric training program on sprint performance and sprint-related temporal-kinematic outcomes in early-adolescent male track-and-field athletes. Participants completed 12 supervised plyometric training sessions integrated into their regular athletics practice. Outcomes were assessed at baseline and after the intervention using field-based sprint testing, video-derived temporal-kinematic analysis, and horizontal jump performance measures. The study was conducted in a low-resource community sport setting in Antioquia, Colombia. The intervention was designed according to the participants' age, training background, and usual sport practice demands, with progressive exercise exposure, supervision, adequate recovery, and safety monitoring throughout the training period.

Outcome Measures

Primary Outcomes (1)

  • Change in 60-m Sprint Time

    Total time to complete a 60-m sprint, measured in seconds under field-based conditions. Lower values indicate better sprint performance.

    Baseline and within 48-72 hours after the final intervention session.

Secondary Outcomes (4)

  • Change in Sprint Split Times

    Baseline and within 48-72 hours after the final intervention session.

  • Change in Video-Derived Sprint Temporal-Kinematic Variables

    Baseline and within 48-72 hours after the final intervention session.

  • Change in Horizontal Jump Performance

    Baseline and within 48-72 hours after the final intervention session.

  • Adverse Events During Training

    From the first intervention session to the final intervention session, approximately six weeks.

Study Arms (1)

Horizontal Plyometric Training

EXPERIMENTAL

Participants completed a six-week horizontally oriented plyometric training program consisting of 12 supervised sessions integrated into their regular athletics training. The program emphasized horizontally directed jumping and bounding actions relevant to sprint acceleration and forward propulsion. Training exposure was adjusted according to participants' age, experience, and tolerance, with progressive loading, technical supervision, adequate rest intervals, and safety monitoring.

Other: Horizontally Oriented Plyometric Training

Interventions

The intervention consisted of 12 supervised sessions of horizontally oriented plyometric exercises delivered over approximately six weeks. Exercises emphasized forward-directed explosive actions and horizontal force application through age-appropriate plyometric tasks. Sessions were conducted under supervision and incorporated warm-up, technical instruction, controlled progression of volume and intensity, rest periods, and monitoring for pain, excessive fatigue, or musculoskeletal discomfort.

Eligibility Criteria

Age12 Years - 13 Years
Sexmale(Gender-based eligibility)
Healthy VolunteersYes
Age GroupsChild (0-17)

You may qualify if:

  • Male early-adolescent track-and-field athletes aged 12-13 years.
  • Active participation in a municipal or community-based athletics training program in Antioquia, Colombia.
  • Minimum recent experience in athletics training according to the records of the local training program.
  • Ability to complete sprint testing, jump testing, and the planned plyometric training sessions.
  • Written informed consent provided by a parent or legal guardian.
  • Written or documented assent provided by the minor participant.

You may not qualify if:

  • Current musculoskeletal injury, pain, or medical restriction that prevents sprinting, jumping, or participation in plyometric training.
  • Any cardiovascular, neurological, orthopedic, or other health condition contraindicating high-intensity physical exercise.
  • Failure to complete baseline or post-intervention assessments.
  • Absence from a substantial portion of the intervention sessions, according to the predefined adherence criteria.
  • Participation in another structured training or research intervention that could substantially affect the outcomes during the study period.

Individual participant data will not be shared because the study involved minors and a small sport-specific sample, which may increase the risk of indirect identification. Results will be reported only in aggregate form. De-identified summary data may be made available upon reasonable request when compatible with the ethics approval, participant consent, and institutional data protection requirements.
