Summary

Background. Plyometric training is an effective strategy to improve power and performance in sprint-based sports; however, evidence regarding its actual effects in athletes during the winter season and its potential influence on the occurrence of health problems remains limited. Objective. To analyse the association between participation in a plyometric exercise programme during the winter pre-season and competitive performance, as well as the occurrence of lower-limb health problems in sprinters. Methods. This will be a prospective observational cohort study with fully online data collection. Federated sprinters or athletes affiliated with athletics clubs will be included. The main exposure will be participation in a plyometric exercise programme (≥2 sessions per week in January). Outcomes will be winter competitive performance (best official time) and lower-limb health problems assessed using the OSTRC-H2 questionnaire. Control variables will include sleep quality (PSQI), internal training load (session-RPE), injury history, and competitive level. Statistical analyses will include linear and logistic regression models adjusted for potential confounders. Expected results. A positive association is expected between engagement in plyometric training and competitive performance, along with a lower frequency of lower-limb health problems, particularly among athletes with adequate sleep quality and a well-balanced training load.
