Welcome to another edition of the ORIEMS FIT RESEARCH DIGEST, where we simplify cutting-edge studies for everyone.

Today’s focus is an exciting research study on how Electrical Muscle Stimulation (EMS), combined with resistance training, can improve both physical and brain functions for middle-aged and older women.

What is This Research About?

• Original Article Name: Effect of Electrical Muscle Stimulation and Resistance Exercise Intervention on Physical and Brain Function in Middle-Aged and Older Women
• Authors: Ngeemasara Thapa, Ja-Gyeong Yang, Seongryu Bae, Gwon-Min Kim, Hye-Jin Park, and Hyuntae Park.
• Published In: International Journal of Environmental Research and Public Health (2023).
• Institutions: Dong-A University’s Department of Health Sciences and Laboratory of Smart Healthcare in Busan, Korea, and the Medical Research Institute of Pusan National University.
• Funding: Supported by the Korea Medical Device Development Fund, highlighting its credibility.

Who Were the Participants?

This study included 48 women aged 40 to 85, divided into three groups:

1. EMS with Resistance Training (ERT) Group
2. Resistance Training (RT) Group
3. Control Group

What Did the Study Find?

The study investigated how a four-week EMS intervention, combined with resistance exercises, impacts physical and brain functions.

Key Positive Findings

1. Improved Muscle Strength and Mass

   • Muscle strength (hand grip) increased significantly in the EMS group.
   • Skeletal Muscle Mass Index (SMI) improved from 6.0 to 6.7 kg/m²—a notable 12% increase.

2. Better Mobility

   • Gait speed improved by 15% (from 1.04 to 1.19 m/s).
   • Significant improvements in lower body mobility tests (Timed Up-and-Go and Sit-to-Stand).

3. Enhanced Brain Activity

   • The EMS group showed a 20% increase in Beta1 brain wave activity, linked to focus and memory.
   • Enhanced connectivity in the brain’s hippocampus, parietal, and temporal regions.

4. Reduced Fatigue

   • Participants found the EMS-assisted exercises less tiring compared to resistance training alone.

Why is This Important?

As people age, they often experience muscle loss (sarcopenia) and slower brain functions. EMS provides a non-invasive, effective way to:

• Build muscle without overloading the joints.
• Boost brain activity, which may protect against cognitive decline.

Why Should You Care?

If you or someone you know is looking for ways to stay strong and active while minimizing joint strain, EMS combined with resistance training could be the solution. It’s a time-efficient and science-backed approach to improving both physical and mental health.
