Brief summary: Injuries to the lower limbs are the most common in rugby and within the lower limbs, the most common are those that affect the ligaments of the knee. That is why we will try to improve knee stability and quadriceps strength.

The aim of this study is to evaluate the effectiveness of performing a pre-workout exercise protocol to improve knee stability and quadriceps strength in rugby players.

Randomized controlled study, simple blind and with follow-up. 30 semi-professional rugby players will be randomized to the two study groups: experimental (pre-training exercise protocol that will include continuous running, squats, and squats and monopodal jumps) and control (without intervention). The intervention will last 4 weeks, with 2 weekly sessions of 15 minutes each. The study variables will be: knee stability (Y-Balance) and quadriceps strength (Single leg hop). The sample distribution will be calculated using the Kolmogorov-Smirnov test. The changes after each evaluation will be analyzed with the t-student test and with an ANOVA of repeated measures, the intra and intersubject effect will be observed. The effect size will be calculated using Cohen's formula.

It is expected to see improvement in knee stability and quadriceps strength in athletes who performed the exercise protocol, after the study period.
