The military parachuting course (MPC) is one of the combat courses offer during the Colombian military career. A literature research shows that this type of courses presents a high incidence and prevalence of injuries in the lower limbs in the landing phase. Additionally, different studies show that the injury rate in the lower limbs is 2-20 every 1000 jumps performed. The most compromised areas are the ankle and knee (ligament and sprains), where 80% of the injuries occur. Moreover, the militaries present a higher injury risk because of variable conditions: high wind speeds, external load and ground conditions. Then, a good landing is very important and it requires a good stability at the knee and a good distribution of the energy at the time of contact with the ground. PURPOSE: Identify the effects of the military parachuting course on the muscular performance of the lower limbs METHODS: Descriptive observational study with an analytical component, in 43 male cadets of the Military School from Colombia, who participated in the MPC for 4 weeks. The performance of the lower limbs was evaluated by using uniaxial force platforms before and after the course. A statistical analysis was performed using the student T test and the Wilcoxon test statistic was used to evaluate changes after the MPC RESULTS: Significant differences were found in the jump height (29.32 ± 3.8 vs. 26.03 ± 3.6 cm, p = 0.0001), peak power (43.29 ± 3.4 vs. 40.62 ± 4.3 W/kg, p = 0.0002), peak landing force (57.65 ± 9.8 vs. 65.15 ± 12.4 N, p = 0.002), eccentric peak velocity (-1.09 ± 0.1 vs. -1.01 ± 0.2 m/s, p = 0.005), concentric mean power ( 23.72 ± 2.5 vs. 22.78 ± 2.8 N/kg, p = 0.022) and eccentric mean power/BM (5.88 ± 1.03 vs. 5.36 ± 1.09 N, p = 0.001). CONCLUSIONS: There is an impact on neuromuscular performance that affects the strength and power of the lower limbs, and increases the ground reaction forces in the landing phase. It could become a risk factor for injuries due to a change in the mechanism of acceptance of load at the landing stage.
