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.

Conditions

  • Knee

Interventions

OTHER

Electrostimulation

Consisting of the use of NMES (biphasic symmetrical pulse, bipolar mode, 50Hz frequency, pulse duration 300 μs at 1:1 ratio) (S82®; Enraf-Nonius BV, Rotterdam, The Netherlands). The self-adhesive electrodes (8x5 cm2 Pals Platinum © type, Axelgaard Manufacturing Co. Ltd, Fallbrook, CA, USA) were placed on the quadriceps muscle. The positives electrodes placed distally on the rectus anterior and vastus externus and negative electrodes were placed proximally on the rectus anterior and vastus internus. The over current program consisted of 8 seconds (s) of work (ON phase) and 8 seconds of rest (OFF phase). The overcurrent program in the ON phase had a rise time of 2 s, a hold time of 4 s and a fall time of 2 s. The intensity of the electric current was increased to the maximum perceived tolerance, achieving a clear contraction without producing fatigue.

OTHER

Blood flow restriction therapy

To attain partial vascular occlusion, a PTS ii portable tourniquet system (Delphi Medical, Vancouver, BC, Canada) with a corresponding size-specific tourniquet was placed around the patient's proximal thigh. This system allows for precise control of cuff pressure throughout training despite the changes in muscle volume that naturally occur while performing exercises. Total limb occlusion pressure (LOP) was identified by determining the pressure required to eliminate a detectable pulse using Doppler ultrasound. Partial vascular occlusion was achieved by setting the tourniquet to 80% of the LOP. This ensured that venous occlusion was obtained while still allowing arterial inflow and was personalized to each patient despite variations in thigh girth, cuff size, and systolic blood pressure. An Easy-Fit Tourniquet Cuff (Delfi Medical, Vancouver, VC, Canada) was used with the PTS ii system.
