- Brief 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.

Group Intervention Description Normal activity Normal activity The subjects included in the control group will perform the same physical activity to improve the strenght until the beginning of the study. The exercises will be done in the same conditions and with the same period (4 days / week) Strength Strength Maximum strength protocol based on a Maximum Repetition (1RM). The aim of the application of the training is to produce an increase in strength based on training with high loads (80% 1RM), individually and covering the muscles of the lower extremity (quadriceps, hamstrings, gluteus maximus).
- Primary Outcome Measures
Name Time Method Change from baseline Maximum strength after treatment and at one month Screening visit, within the first seven days after treatment and after one month follow-up visit The RM strength assessment protocol will be used. In the squat you will be asked to bend your knees and hips over ninety degrees, then return to the starting position. In deadlift, you will be asked to take the bar from the height of the hips to just below the label, keeping the trunk upright, facing the front. Both in the quadriceps chair and in the hamstring curl, you will be asked to perform the lifting of the indicated weight, following the movement allowed by the machine to be used. The greater the weight lifted (in kg), the greater muscular strength.
- Secondary Outcome Measures
Name Time Method Change from baseline lower limb functionality after treatment and at one month Screening visit, within the first seven days after treatment and after one month follow-up visit The functionality was measured with the Standing Long Jump test, with the subject standing, behind a demarcated line aligns the tips of the feet. You will be asked to squat by throwing your arms behind you and ordering a bipodal jump, with impulse of the lower limbs being helped by the swing of the upper ones. The distance traveled will be measured in centimeters and the test will only be valid when the subject lands with both limbs without losing balance. The measurement is made from the starting line to the landing point coinciding with the tip of the subject's feet. This test is done in a monopodal way. At greater distance (cm), greater functionality of lower limbs.
