Summary

The main goal of this randomized controlled trial (RCT) is to evaluate the chronic effects of using instep weights on technical, physical (conditional), and perceptual parameters in amateur male soccer players.

The secondary objective will be to propose a training methodology using instep weights to enhance athletic performance.

The following hypotheses are formulated based on the objectives outlined previously.

Hypothesis 1: the use of instep weights will enhance performance in ball striking speed, change of direction ability, and repeated sprint capacity.

Hypothesis 2: the use of instep weights will negatively affect performance in ball striking accuracy and ball control.

Hypothesis 3: the use of instep weights will not produce adverse effects on perceived exertion, groin pain or reduce maximal adductor, quadriceps and hamstring muscle contraction values.

Interventions

OTHER

Instep weights use

Players will perform their scheduled training sessions while wearing a 150-gram instep weight. The use of instep weights in the intervention group will be introduced progressively and gradually, increasing both the frequency of sessions and the duration of their use. During weeks 1-2, instep weights will be used in one training session per week. During weeks 3-5, will be used in two training sessions per week. And during weeks 6-8, will be used in three training sessions per week. The duration of instep weight usage within each session will increase by 5% weekly, starting at 40% in Week 1 and reaching 75% by Week 8.
