Introduction: Soccer is a sport of several motor actions, which causes a constant imbalance in the body, emphasized at an early age, is the proprioception of a strategy to strengthen the balance in initiation players. Objective: To assess the effects of a short-term proprioceptive intervention on the balance deficit in lower limbs of child soccer players. Methods: Quasi-experimental cross-sectional study of a population of 12 child soccer players (10-12 years), a four[1]week proprioceptive training was applied, emphasizing specific aspects to enhance body balance in its static phase. Three variables were assessed for each foot from the application of the Y Balance Test in two moments of sports preparation. Results: The test used determined a level of statistical significance: Right Foot Left Movement (p= 0.005), Right Foot Central Movement (p= 0.004), Right Foot Right Movement (p= 0.005), Left Foot Left Movement (p= 0.003), Left Foot Central Movement (p= 0.003), Left Foot Right Movement (p= 0.004). Conclusions: Short-term proprioceptive training is effective in significantly improving the static balance in the lower extremities in child soccer players.
