Brief Summary

Introduction: The loss of normal values of ROM due to the lack of flexibility and strength in the hip flexors, quadriceps and hamstrings in soccer players can cause a loss of mobility of the hip and knee joint. Proprioceptive neuromuscular facilitation is an active-assisted stretching technique used to improve flexibility and therefore the ranges of joint mobility.

Aim. To assess the effectiveness of an intervention by proprioceptive neuromuscular facilitation in the improvement of flexibility and strength in the hamstring, hip flexor and quadriceps musculature compared to conventional stretches in football players.

Study design. Randomized, multicentric, single-blind clinical study. Methods. The 30 players will be randomly assigned to the study groups: experimental (proprioceptive neuromuscular facilitation and static stretches) and control (static stretches). The treatment will last 6 weeks, with two sessions a week of 5 minutes each. The study variables will be the range of hip mobility (using goniometry), hamstring flexibility (using the EPR test, inclinometer) and the strength of hip flexors, quadriceps and hamstrings (through the RM test). A descriptive statistical analysis will be carried out calculating the main statistical characteristics and after calculating the normality of the sample (test Kolmogorov- Smirnov), the differences between evaluations in each group (t-student test) and the intra- and intersubject effect will be calculated (ANOVA of repeated measures).

Expected results. Improved hip mobility, hamstring flexibility and strength in hip flexors, quadriceps and hamstrings muscles.

Study Groups

Proprioceptive neuromuscular facilitation

Each session will last 5 minutes for each subject, taking place two sessions a week, in a period of 6 weeks. The intervention will be made at the beginning of the training session. The technique will be carried out with the subjects in the positions of supine, prone and lateral position, for the flexor muscles of the hip, hamstrings and quadriceps, where the musculature and the joint to be treated will be taken to a range of functional mobility

Group Type: EXPERIMENTAL

Experimental

Intervention Type: OTHER

The technique will be carried out with the subjects in the positions of supine, prone and lateral position, for the flexor muscles of the hip, hamstrings and quadriceps, where the musculature and the joint to be treated will be taken to a range of functional mobility. The subject will be asked to perform an isometric contraction, with a series of 3 seconds for sustained contraction and a rest between contraction of 2 to 3 seconds after activating the Golgi apparatus, making an inhibition of the stimulus and bringing the joint and muscle to the highest possible range of motion without pain.

Muscle stretching

Each session will last 5 minutes for each subject, taking place two sessions a week, in a period of 6 weeks. The intervention will be made at the beginning of the training session. It will be done for the hip, quadriceps and hamstring muscles with a voluntary antagonist activation to relax the agonist muscle.

Group Type: ACTIVE_COMPARATOR

Control

Intervention Type: OTHER

The active stretching technique will be performed for the hip, quadriceps and hamstring flexors with a voluntary antagonist activation to relax the agonist muscle, holding the movement to be performed for 30 seconds to stimulate the neuromuscular spindle and produce a relaxation of the muscle fibers.
