About

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.

65 participants in 2 patient groups

Strength

Experimental group

Description:

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).

Treatment:

Other: Strength

Normal activity

Active Comparator group

Description:

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)

Treatment:

Other: Normal activity
