Letโs explore how this innovative technology can take your training to the next level.
What is this research about?
This research, titled "Electrical Stimulation and Muscle Strength Gains in Healthy Adults: A Systematic Review," evaluated how EMS impacts muscle strength.
The study analyzed past research on EMS protocols, strength adaptations, neural adaptations, and its use as a standalone or combined tool with traditional resistance training.
Who conducted this research, and where?
- Authors: Dr. Swarup Mukherjee, Jeryn Ruiwen Fok, and Dr. Willem van Mechelen.
-
Institutions:
- Nanyang Technological University (NTU) in Singapore, a world-class university known for sports science innovations.
- Amsterdam UMC, one of Europeโs leading research centers for health and sports sciences.
- Funding: Supported by their respective institutions and research grants focused on advancing sports and health sciences.
These researchers bring a wealth of expertise, and their institutions are renowned for producing influential studies in sports science.
Who participated in the research?
The review included 10 studies involving 174 healthy adults aged 18โ64 years.
These participants were both men and women, ranging from recreational exercisers to fitness enthusiasts.
How was the research conducted?
- Study Design: The researchers followed the PRISMA 2020 guidelines for systematic reviews, ensuring rigor and credibility.
- Methods Reviewed: They analyzed randomized controlled trials (RCTs), crossover trials, and nonrandomized studies that compared EMS treatments to control groups using either no intervention or sham training.
What did they find?
General Explanation
All 10 studies demonstrated that EMS significantly increased muscle strength, whether used alone or in combination with traditional strength training. EMS effectively activates muscles, making it a valuable tool for building strength.
Specific Evidence Supporting the Findings
-
Muscle Strength Gains:
- Every study in the review reported statistically significant increases in muscle strength in participants who used EMS.
- For lower body training, EMS resulted in strength improvements of 15%โ28% over the study durations (6โ12 weeks).
-
Combination with Traditional Training:
- Five studies combined EMS with Voluntary Resistance Training (VRT) and found 20% faster strength gains compared to resistance training alone.
- This highlights EMS as a complementary tool to amplify results from traditional exercises.
-
Focus Areas:
- Eight studies targeted lower limb muscles, showing 18%โ25% strength increases in quadriceps and hamstrings.
- Two studies focused on elbow flexors, with strength gains averaging 12%โ16%.
-
Adaptability Across Protocols:
- EMS protocols varied, with treatment durations ranging from 15 to 45 minutes per session, conducted 2โ4 times per week over 6โ12 weeks. Despite these differences, all protocols led to measurable strength improvements.
Why could EMS be helpful for you?
EMS devices can:
- Enhance strength training: EMS is proven to boost muscle strength even without traditional resistance exercises.
- Save time: EMS sessions are effective in as little as 15 minutes, making it ideal for busy individuals.
- Provide flexibility: EMS works well for targeting specific muscle groups, especially in recovery or rehab scenarios.
How can this help EMS device users?
For users of EMS devices:
- Faster Gains: Add EMS to your regular workouts to accelerate your strength-building progress.
- Customizable Protocols: Experiment with session durations and frequencies based on your schedule.
- Accessibility: Use EMS as an independent workout tool on days when you canโt hit the gym.
