EMS Combined With Resistance Training in Weight Lifters

Официальное название

Effects of Electrical Muscle Stimulation Combined With Resistance Training on Muscle Mass, Strength, Body Composition, and Power in Weight Lifters

Обзор

The purpose of this randomized controlled trial is to determine the effects of Electrical Muscle Stimulation (EMS) combined with resistance training on muscle mass, muscular strength, body composition, and power in trained weightlifters. Participants will be randomly allocated into two groups: one receiving resistance training alone and the other receiving EMS combined with resistance training. The intervention will be conducted for eight weeks, and outcome measures will be assessed at baseline, mid-intervention (4 weeks), and post-intervention (8 weeks). The findings of this study may provide evidence regarding the additional benefits of EMS when combined with conventional resistance training programs in enhancing muscular performance among trained athletes.

Подробное описание

Resistance training is widely used to improve muscle mass, strength, and physical performance in athletes. Electrical Muscle Stimulation (EMS) has recently gained attention as an adjunctive modality that may enhance neuromuscular activation and training adaptations when applied during exercise. EMS delivers electrical impulses to skeletal muscles through surface electrodes, which may recruit additional motor units and improve muscular performance outcomes.

This randomized controlled trial aims to evaluate the effectiveness of EMS when combined with resistance training in comparison to resistance training alone in trained male weightlifters. Participants will undergo an eight-week intervention consisting of supervised training sessions three times per week. Outcome measures related to muscle mass, strength, body composition, and power will be recorded at baseline, at four weeks, and at eight weeks.

The study findings may provide insight into the practical application of EMS in sports training and rehabilitation settings and its role in improving muscular performance outcomes in trained individuals.

Вмешательства

• Другое EMS + Resistance Training
  This group will combine the benefits of both EMS and Resistance Training to maximize muscle mass, strength, and body composition improvements using both EMS and RT (18). EMS will be applied to muscles using a frequency-specific protocol. EMS treatment according to the parameters defined as frequency (85 Hz), pulse duration (400 1s), and the duty cycle (10s on: 50s off). Exercises: A complementary schedule of EMS and resistance exercises. Frequency: 3 times per week (Tuesday, Thursday, Saturday)
• Другое Resistance Training Only
  This protocol will emphasize muscle strengthening through resistance training to improve strength and muscle mass through traditional resistance training methods (7). Exercises: A selection of exercises focusing on muscle mass and strength. Compound exercises (such as squats, deadlifts, bench press) and isolation exercises (such as bicep curls, triceps extensions) Frequency: 3 times per week (Monday, Wednesday, Friday) for 8 weeks.
