Welcome to another edition of ORIEMS FIT Research Digest, where we bring you fascinating research that sparks curiosity and inspires learning. In this post, we explore a groundbreaking study that was recently published in the Journal of NeuroEngineering and Rehabilitation, a prestigious journal in the field of neuroengineering, based in the United Kingdom.
This research, conducted by top scientists from South China Normal University in Guangzhou, China, explores how electrical muscle stimulation (EMS) can potentially prevent muscle weakness and maintain muscle strength during periods of inactivity. Could this technology be the key to muscle preservation in situations like bed rest, space travel, or rehabilitation? Let’s dive in!
Research Details
- Original Research Title: An Electrical Stimulation Intervention Protocol to Prevent Disuse Atrophy and Muscle Strength Decline: An Experimental Study in Rats
- Authors: Haiwang Shi, Fan Li, Fulong Zhang, Xiaobei Wei, Chengyi Liu, and Rui Duan
- Published in: Journal of NeuroEngineering and Rehabilitation, 2023
- Institution: South China Normal University, Guangzhou, China – a prestigious institution known for advanced sports and rehabilitation research.
- Funding: The study was funded by the National Natural Science Foundation of China and Guangzhou Scientific Research Grant.
What’s This Research About?
This study focuses on Electrical Stimulation (ES) and its potential to prevent muscle atrophy (muscle shrinking) and maintain strength during times of little to no movement, such as bed rest or microgravity in space. It explores different frequencies of stimulation, combining high-frequency (HFES) and low-frequency (LFES) protocols.
Who Was This Study Conducted On?
The study used a controlled model with 43 adult male rats. These rats underwent a "tail suspension" method to mimic muscle inactivity.
Key Findings
The researchers found that EMS can significantly reduce muscle loss and improve strength during inactivity. Here are the key results:
-
Improved Muscle Mass and Strength:
- HFES before inactivity increased the muscle mass of the soleus muscle by 62%.
- Combining HFES before inactivity with LFES during inactivity increased soleus muscle fiber size (CSA) by 90% and muscle mass by 49%.
-
Increased Muscle Fiber Quality:
- HFES and LFES improved the type of muscle fibers that are more fatigue-resistant:
- Soleus muscle oxidative fibers increased by 15–18%.
- Gastrocnemius fatigue resistance improved by up to 38%.
- HFES and LFES improved the type of muscle fibers that are more fatigue-resistant:
-
Restored Strength:
- The combination of HFES before and LFES during inactivity resulted in a 66% improvement in single muscle contraction strength and returned fatigue resistance to normal levels.
Why EMS Could Help in Real Life
The study suggests that EMS can:
- Help people recovering from surgery or injury maintain muscle strength.
- Support astronauts or anyone experiencing long-term immobility.
- Improve recovery in individuals with limited ability to perform physical exercise.
How This Study Could Help EMS Device Users
If you use EMS devices like those offered by ORIEMS FIT, this research supports their potential to:
- Preserve muscle mass and prevent weakening during periods of low activity.
- Enhance fatigue resistance, making everyday tasks easier.
- Improve muscle quality through consistent and guided use.
