Comparison of combining microcurrent with resistance training versus resistance training alone on performance variables of university athletes:A Randomized controlled trial

Summary of the Study on Microcurrent Therapy and Resistance Training****Introduction: Microcurrent Therapy (MCT) is a non-invasive electrotherapy using low-intensity currents (less than 1 mA), similar to natural bioelectric currents produced by the human body. Developed in the 1970s, MCT has been shown to promote tissue repair, increase mitochondrial ATP production, and enhance muscle recovery. The therapy has applications in increasing muscle protein synthesis, improving endurance, reducing muscle soreness, and aiding in fat reduction. However, research regarding the optimal parameters for MCT, such as intensity, frequency, and treatment duration, remains limited.

Research Gap: While some studies suggest benefits from combining MCT with exercise, there is insufficient evidence regarding the specific dosage and parameters that optimize the effectiveness of MCT when combined with resistance training. Poor research design and inconsistent sample types in past studies have hindered clear conclusions. This study aims to address these gaps and investigate the effects of MCT alongside resistance exercise.

Significance of the Study: This study aims to contribute to existing literature by determining the additive effects of microcurrent in resistance training, specifically targeting back muscles. The findings may offer insight into optimal intervention protocols and highlight MCT’s potential as a tool for improving athletic performance, reducing fatigue, and alleviating delayed-onset muscle soreness (DOMS).

Research Questions:

• Does microcurrent provide additional benefits when combined with resistance training in terms of maximum voluntary isometric contraction (MVIC), isometric strength, and explosive performance?

Objectives:

1. To analyze the effects of microcurrent combined with resistance training on back muscles in terms of percentage MVIC.
2. To investigate the additive effects of microcurrent with resistance training on back muscle isometric strength.
3. To identify the optimal training method for enhancing strength and explosive performance in university athletes.

This study aims to determine whether microcurrent therapy enhances resistance training outcomes and to establish the most effective protocols for combining these two modalities in athletic training.

Study Summary:Objective: The study investigates whether combining microcurrent therapy with progressive resistance training improves back muscle strength and performance (MVIC, isometric strength, and explosive strength) more than resistance training alone in university athletes.

Hypotheses:

• Null Hypothesis: No significant difference in muscle strength or performance between the two training methods.
• Alternate Hypothesis: Microcurrent combined with resistance training results in significant improvements.

Study Design:

• Type: Pre- and post-randomized controlled trial with two groups.
• Duration: 6 weeks.
• Sample Size: 30 participants (calculated with G Power to accommodate potential dropouts).
• Location: Jamia Millia Islamia, New Delhi.

Participants:

• Inclusion: University athletes aged 19-28 years, 2+ years of sports experience, BMI 18.5-24.9, no previous microcurrent exposure.
• Exclusion: Individuals with cardiovascular, respiratory, or musculoskeletal issues, or who had recent surgeries.

Randomization: Participants are randomly divided into two groups:

1. Group A: Progressive Resistance Training only.
2. Group B: Microcurrent + Progressive Resistance Training.

Training Protocol:

• Progressive Resistance Training: 3 sessions per week, each lasting 40 minutes, using TheraBand for core exercises (e.g., curl-ups, bridges, push-ups).
• Microcurrent Protocol (Group B): Same as Group A but with additional microcurrent therapy at 8 Hz frequency and 25 microamperes intensity for 40 minutes.

Outcome Measures:

1. Counter Movement Jump (CMJ): Measures explosive strength through vertical jump height.
2. Gait ON® Posture Analysis: Assesses body alignment and posture.
3. Back Held Dynamometer: Measures isometric strength of back muscles.
4. EMG (Electromyography): Monitors muscle activation to assess %MVIC.

Instrumentation: Includes a stadiometer, digital scale, cones, TheraBand, EMG system, microcurrent device, and dynamometer.

Data Collection:

• Pre-study: Informed consent, familiarization with tests, and baseline measurements (height, weight, muscle strength, EMG).
• Post-study: Follow-up assessments after 6 weeks of training.

Conclusion: This study aims to compare the effects of microcurrent therapy combined with progressive resistance training versus resistance training alone on strength and performance in athletes, using several key measures of muscle function.
