Horizontal Plyometric Training and Sprint Mechanics in Early-Adolescent Track-and-Field Athletes (HPT-Sprint You)

30 avril 2026 mis à jour par: Édison Andrés Pérez Bedoya, Federal University of Vicosa

Effects of Twelve Sessions of Horizontally Oriented Plyometric Training on Sprint-Related Temporal-Kinematic Outcomes in Early-Adolescent Track-and-Field Athletes: A Field-Based Exploratory Pre-Post Study

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.

Description détaillée

Horizontally oriented plyometric training may be relevant for sprint development because sprint acceleration and the transition toward maximal sprinting velocity require rapid force production and effective forward orientation of propulsive actions. However, evidence in early-adolescent track-and-field athletes remains limited, particularly in community-based sport contexts where coaches rely on accessible field tests and video-based kinematic procedures.

This exploratory single-arm intervention study evaluated pre-post changes after 12 sessions of horizontally oriented plyometric training in male early-adolescent track-and-field athletes aged 12-13 years. The training program was delivered over approximately six weeks and was integrated into the athletes' regular training routine. The intervention emphasized horizontally directed plyometric actions and was implemented with progressive exposure, technical supervision, adequate rest periods, and suspension criteria in case of pain, excessive fatigue, musculoskeletal discomfort, or any safety concern.

Sprint performance and sprint-related temporal-kinematic variables were assessed before and after the intervention. Field-based assessments included sprint time and video-derived sprint variables, complemented by horizontal jump performance. Because the study was conducted with minors and a small sport-specific sample, all data will be reported in aggregate form, and no individual participant data will be publicly shared.

Armes et Interventions

Groupe de participants / Bras
Intervention / Traitement
Expérimental: Horizontal Plyometric Training
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.
Autre: Horizontally Oriented Plyometric Training
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.
