Summary

Introduction. The members of the Military Emergency Unit must be physically prepared for any type of situation where required, although their strength training does not follow any concrete structure. Structured training of maximum strength aims to increase the recruitment of different types of fibers, and the increase in the size of these. Objectives: To evaluate the effectiveness of a maximum strength training protocol in lower extremity functionality in military personnel aged 25 to 45 years. Study design. Randomized, single-blind clinical study with follow-up period. Methodology. 65 male subjects will be recruited, who will be randomly assigned to the two study groups: experimental (structured strength training) and control (they will continue with their usual routine of free training). The intervention will last for 8 weeks, with 2 weekly sessions, lasting 20 minutes, with three evaluations (baseline, posttreatment and follow-up). The study variables will be: lower limb functionality (assessed by Standing Long Jump and Single Leg Hop tests), and quadriceps and hamstring strength (evaluated with the MRI measurement for each exercise). To perform the analysis of normality, the Kolmogorov Smirnof test will be used. In case of homogeneity, with the t-student test of repeated measures and an ANOVA of repeated means, the difference between the different evaluations and the intra and intersubject effect, respectively, will be calculated. Expected results. Effectiveness of structured training of maximum strength in functionality of lower extremities.

Interventions

Type	Name	Description
OTHER	Strength	In the performance of the squat exercise (Back Squat), the subjects will be standing, with an Olympic bar behind their neck, supported on both trapezoids, while the hands will help to hold and stabilize the bar, taking it from below. For hamstring curl, the subject will be in the prone position, clinging to the backrest, with the legs under the arm that lifts the weight. The deadlift exercise will be performed from the standing posture, holding the bar with your arms extended and the trunk straight, while your hands will hold the bar at the height and separation of the hips. Finally, in the quadriceps chair the subject will find himself sitting with his back straight and supported on the back of the seat, while the legs will go under the arm that lifts the weight.
OTHER	Normal activity	The subjects included in the control group will continue to perform the same strength training plan that they did before starting this one. The periodicity will be the same (4 days / week) and with the same intensity.
