- Detailed Description
The objective is to know the effects of Neuromuscular Electrical Stimulation (NMES) and its combination with Blood Flow Restriction (BFR) Therapy in healthy amateur female soccer players.
For this purpose, a randomized clinical trial will be performed: 20 amateur female soccer players were distributed in two groups (control group n=10; experimental group n=10). In the control group, NMES (symmetrical biphasic rectangular pulse, 350 μs and 80Hz) combined simultaneously with active exercise in knee extension (75 repetitions in 4 sets, 20% 1RM, 30 seconds rest between sets) was applied. The experimental group performed the same intervention combined with blood flow restriction (BFR) therapy (80% of arterial occlusion pressure). The variables measured were muscle strength, muscle volume and static proprioception.

Group Intervention Description Control group Electrostimulation This arm only received the Neuromuscular and Muscular Electrical Stimulation (NMES) intervention. Experimental group Electrostimulation This arm received the intervention with NMES and Blood flow restriction (BFR). Experimental group Blood flow restriction therapy This arm received the intervention with NMES and Blood flow restriction (BFR).
- Primary Outcome Measures
Name Time Method Muscular Strenght During the intervention, at day 1 It was performed using an isokinetic dynamometer (Kineo, Globus, Codognè, Italy). The maximum peak force that the user can perform was measured by means of the concentric-eccentric isokinetic force test. The patient is placed seated on the seat of the machine and with the dominant lower limb, performs 5 contractions with the maximum force, obtaining the concentric and eccentric peak force.
Muscle volume During the intervention, at day 1 It was performed by means of the thigh perimeter, using a tape measure. The superior pole of the patella is selected as an anatomical reference point and four segments are marked from it, located at 5, 10, 15 and 20 centimeters respectively (95). Subsequently, placing the beginning of the measuring tape at the mark of the segment in question, the thigh is encircled keeping the beginning of the tape fixed, which will coincide with a measurement of the tape when it is reached. This measurement is taken before the start of the quadriceps work with the knee extension exercise and at the end of the 15 minutes of rest after this work.
- Secondary Outcome Measures
Name Time Method Knee joint repositioning During the intervention, at day 1 It was performed through the ability to perceive and reproduce an articular angle previously represented and explained passively. The angles are photographed and measured using the SAPO® computer program, by means of the placement of four marked points on the greater trochanter, lateral epicondyle of the femur, head of the fibula and peroneal malleolus. To perform this procedure, the user must memorize two positions, knee flexion of 90º and knee flexion of 135º, taking 3 photographs of each position in both seated and prone positions.
