Brief Summary

This study evaluates the effect of training with neuromuscular electrical stimulation (NMES) associated with vascular occlusion of the lower limbs, for increased strength and hypertrophy of the quadriceps muscle of professional basketball athletes.

Conditions

Electric Stimulation Therapy; Muscle Strength

Keywords

Physical Therapy; Rehabilitation; Neuromuscular Electrical Stimulation; Muscle Strength

Outcome Measures

Primary Outcomes (2)

• Analysis of muscle strength through isokinetic dynamometer (N / M).

  The association of NMES and vascular occlusion of the lower limbs increases the isokinetic torque?

  12 weeks

• Analysis of hypertrophy through the cross section area of the muscle via ultrasound (mm).

  The association of NMES and vascular occlusion of the lower limbs increases the cross-sectional area of the muscle?

  12 weeks

Secondary Outcomes (5)

• Analysis of GH Level by blood test (mg / L)

  12 weeks

• Analysis of IGF-1 Level by blood test (mg / L)

  12 weeks

• Analysis of Star Excursion Balance Test (cm)

  12 weeks

• Performance Analysis in Illinois agility test (Time in seconds)

  12 weeks

• Muscle electromyographic analysis through the median frequency (Hz) and root mean square (RMS)

  12 weeks

Study Arms (3)

Control

NO INTERVENTION

Are not subject to any intervention.

Electrotherapy

EXPERIMENTAL

The athletes will be submitted to NMES of bilateral quadriceps. The stimulation will be held in order to induce the move flexion / extension involuntary knee in extension machine, with resistance of 30% of maximum voluntary strength.

Device: NMES

Electrotherapy + Vascular Occlusion

EXPERIMENTAL

The same as in Electrotherapy group, athletes are subjected to NMES associated total vascular occlusion of the members below the level of the groin.

Device: NMES; Device: Vascular Occlusion

Interventions

NMES DEVICE

Neuromuscular Electrical Stimulation

Electrotherapy; Electrotherapy + Vascular Occlusion

Vascular Occlusion DEVICE

Restriction of sanguine flow to the lower limbs

Electrotherapy + Vascular Occlusion
