Study Overview
Brief Summary
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.
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.

Outcomes
Primary Outcomes
Muscular Strenght
Time Frame: 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
Time Frame: 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 Outcomes
- Knee joint repositioning(During the intervention, at day 1)
