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.

Outcome Measures

Primary Outcomes (1)

• Change from baseline flexibility of the hamstring muscles after treatment and at month

  The measurement instrument to measure the flexibility of the hamstring muscles is the passive elevation of the straight leg with an inclinometer (model ISOMED, Inc., Portland, OR) to be placed on the tibia (as distal as possible). The physiotherapist will maintain the extension of the knee and the leg will be lifted by the evaluator to a hip flexion, until the subject indicates pain in the hamstring muscles, when the evaluator perceives hip flexion restriction or when a posterior pelvic tilt occurs. The contralateral knee of the subject will remain in extension. The unit of measurement of the test is the maximum angle read from the inclinometer at the point of maximum flexibility, in degrees, with the normative range of 75 to 80 degrees (the greater the degree of flexibility, the greater the flexibility).

  Screening visit, within the first seven days after treatment and after one month follow-up visit

Secondary Outcomes (2)

• Change from baseline the range of motion of hip after treatment and at month

  Screening visit, within the first seven days after treatment and after one month follow-up visit

• Change from baseline strength of upper limbs after treatment and at month

  Screening visit, within the first seven days after treatment and after one month follow-up visit

Study Arms (2)

Proprioceptive neuromuscular facilitation

EXPERIMENTAL

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

Other: Experimental

Muscle stretching

ACTIVE COMPARATOR

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.

Other: Control

Interventions

Experimental 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.

Proprioceptive neuromuscular facilitation

Control 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.
