Horizontal Plyometric Training and Sprint Mechanics in Early-Adolescent Track-and-Field Athletes

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.
