简要总结
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.
详细描述
Participants who meet the eligibility criteria will be invited to participate in the study and, after signing the informed consent form, will perform initial clinical evaluation and will be randomized into two groups, being: control group (CG) and intervention group (GI) - using the medium-frequency alternating current. Each group will consist of 15 subjects who will have as dependent variables, the evaluation of the following items: peak muscle torque, analysis of ventilatory anaerobic thresholds, running economy and maximal oxygen consumption.
The intervention with the NMES will be considered as an independent variable. All groups will have the dependent variables evaluated before and after the intervention, which will consist of 18 sessions (6 weeks). The NMES training will be performed 3 times a week and will never be applied for two consecutive days, as shown in the flowchart All individuals, being they of the CG or the GI will perform a running training (TC), between 15 and 40 km per week and will be guided how to perform them, and the GI patients will perform a muscle strengthening protocol with NMES, which will be carried out in a specific place and prepared for intervention, in addition to the TC.

结局指标
主要结局
Isokinetic dynamometer
时间窗: 6 weeks
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.
次要结局
- Racing economy(6 weeks)
- Analysis of Ventilatory Anaerobic Threshold(6 weeks)
- Maximum oxygen consumption(6 weeks)
