Horizontal Plyometric Training and Sprint Mechanics in Early-Adolescent Track-and-Field Athletes
Colombia9 participantsStarted 2022-07-01
Plain-language 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.

* 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.
Exclusion Criteria:
* 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.

* Participation in another structured training or research intervention that could substantially affect the outcomes during the study period.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
