Weighted vs Unweighted Plyometric Conditioning on Vertical Jump Performance in Young Male Soccer Players (PAPE-JUMP)
Differential Time-Course Effects of Weighted and Unweighted Plyometric Conditioning on Vertical Jump Performance in Young Male Soccer Players
Explosive lower-limb power is essential for soccer performance and contributes to jumping, sprinting, and rapid changes of direction. Plyometric exercises are commonly used during warm-up to improve neuromuscular readiness and may enhance subsequent athletic performance through post-activation performance enhancement (PAPE). However, it remains unclear whether adding external load during plyometric conditioning provides greater benefits than performing the same exercises without additional load.
The purpose of this study is to compare the acute effects of weighted and unweighted plyometric conditioning on vertical jump performance in young male soccer players. Participants complete two experimental sessions separated by 48 hours. In one session, they perform a standardized single-leg plyometric protocol without external load, and in the other session they perform the same protocol while wearing a weighted vest equivalent to 10% of their body mass. Vertical jump height is assessed before exercise and at several time points after the conditioning activity to examine the time course of performance changes.
The findings of this study are expected to improve understanding of the optimal use of weighted plyometric conditioning during warm-up and provide practical guidance for coaches and sports practitioners seeking to maximize explosive performance before training and competition.

Experimentální: Weighted Plyometric Conditioning
Participants performed a standardized single-leg plyometric conditioning protocol while wearing a weighted vest equivalent to 10% of their body mass.
Vertical jump performance was assessed at baseline and at 15 seconds, 2 minutes, 4 minutes, and 8 minutes after the conditioning activity.
|
Participants completed three sets of ten single-leg plyometric repetitions while wearing a weighted vest corresponding to 10% of their body mass.
Sessions were separated by 48 hours, and jump performance was measured before and after the conditioning protocol.

Aktivní komparátor: Unweighted Plyometric Conditioning
Participants performed the same standardized single-leg plyometric conditioning protocol without external load.
Vertical jump performance was assessed at baseline and at 15 seconds, 2 minutes, 4 minutes, and 8 minutes after the conditioning activity.
