简要总结
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.
详细描述
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.

结局指标
主要结局
Mid Upper Arm Circumference
时间窗: Baseline, Week 4, Week 8
This measurement helps assess muscle size and mass in the upper arm. It is a simple, non-invasive way to estimate changes in muscle growth
Thigh Circumference
时间窗: Baseline, Week 4, Week 8
This measures the circumference of the thigh, another area where muscle growth can be tracked. It gives insights into lower-body muscle mass
Skinfold Thickness
时间窗: Baseline, Week 4, Week 8
This refers to the measurement of skinfolds at specific body sites (such as triceps, abdomen, and thigh) using calipers. It provides an estimate of subcutaneous fat and indirectly reflects muscle mass as well
30s Sit-to-Stand Test
时间窗: Baseline, Week 4, Week 8
This test measures functional lower-body strength by counting how many times a person can rise from a chair in 30 seconds. It assesses leg strength and endurance
Arm Curl Test
时间窗: Baseline, 4 Week, 8 Week
This evaluates upper-body strength by counting how many bicep curls a person can perform in 30 seconds using a set weight. It focuses on arm muscle endurance and strength
1RM Estimation (One Repetition Maximum)
时间窗: Baseline, 4 Week, 8 Week
This measures the maximum amount of weight a person can lift in 1 repetition for a given exercise (like squats). Estimating the 1RM helps evaluate maximal strength
Vertical Jump Test (Sayers Equation)
时间窗: Baseline, 4 Week, 8 Week
This test measures lower-body power by assessing how high an individual can jump from a standing position. The Sayers equation is used to calculate power output from the vertical jump height
Standing Long Jump
时间窗: Baseline, 4 Week, 8 Week
This test assesses lower-body power and strength by measuring how far an individual can jump forward from a standing start
