Brief Summary

Introduction: The use of neuromuscular electrical stimulation (NMES) in athlete training has become an increasingly common feature among competition teams. Among the main benefits of NMES are the increase in muscular strength and improvement in athletes' performance. Surveys demonstrate the benefits of basketball, volleyball, soccer, swimmers and Olympic lifters using NMES, but no studies have been conducted on runners. Objectives: To evaluate the effects of 6 weeks of training with NMES, on knee peak torque (PT), ventilatory anaerobic threshold, maximum oxygen consumption (VO2max) and running economy in recreational runners. Methods: Randomized clinical trial involving 30 long distance runners, being randomly distributed in 2 groups of 15 participants each. All individuals will perform isokinetic evaluation of the lower limbs and ergospirometry. After these evaluations, all athletes will perform the same running training (CT), in addition to the CT the intervention group will perform NMES on the knee extensors 3 times a week for 15 minutes.

Outcome Measures

Primary Outcomes (1)

• Isokinetic dynamometer

  The computerized isokinetic muscle evaluation will be performed in the Cybex Norm isokinetic dynamometer (Cybex International, Inc., Ronkonkoma, LI, New York), at the Physiotherapy Clinic of Universidade Cidade de São Paulo (UNICID). The movement performed during the test will be that of isometric, concentric and eccentric extension of the two knees, to measure peak torque, using angulations of 90 to 60 degrees of knee and 3 maximum voluntary contractions.

Secondary Outcomes (3)

• Maximum oxygen consumption

Interventions

NMES and Run OTHER

NMESIn this exercise protocol for quadriceps strengthening using NMES, the medium-frequency alternating current (1KHz with 10% of the work cycle) 4 will be used. The total daily training time is 900sec (15min), it is expected to perform 45 contractions per training, with three workouts per week for six weeks. RUN: It will be allowed to carry out training drills that comprise 15-40Km per week, being allowed a minimum of 2 and a maximum of 3 training sessions per week, not being able to carry out drills of explosion and during each training must be covered at least 5km and at most 15km. These limitations were based on the American College of Sports Medicine (ACSM) cardiorespiratory training guidelines to minimize confounders of cardiopulmonary performance.
