Research Title

"Assessment of the Strength Parameters of the Quadriceps Femoris Muscles in Polish University Students after a 3-Week Program of Neuromuscular Electrical Stimulation Using the RSQ1 Method"

Who Conducted This Research?

• Authors: Aleksandra Rywacka, Małgorzata Stefańska, and Alicja Dziuba-Słonina.
• Where: Conducted at Wroclaw University of Health and Sport Sciences, Wroclaw, Poland.
• Institute Prestige: Renowned for advanced research in rehabilitation and sports science.

What Was This Study About?

The researchers investigated how a 3-week EMS training program using the RSQ1 method impacted the strength of the quadriceps femoris muscles in young, healthy individuals.

They compared the results to a traditional exercise program without EMS.

Who Participated in This Study?

• Participants: 19 university students (11 women and 8 men) aged 22–30 years.
• Health Criteria: All participants were physically active but not professional athletes, with no recent injuries or chronic conditions.

What Was the Research Method?

• Duration: The study lasted 3 weeks, with 10 sessions total.
• EMS Group: Used the RSQ1 device for 30-minute sessions combined with exercises like squats and sit-to-stand movements.
• Control Group: Performed the same exercises but without EMS.

Key Findings

General Explanation

The EMS program showed similar effectiveness to traditional training, making it a viable alternative for individuals unable to perform high-intensity workouts.

Significant improvements were noted in muscle strength and circumference for the EMS group.

Specific Evidence Supporting the Positive Findings

1. Improved Muscle Strength:

   • Peak torque (muscle strength measure) in the left knee flexor muscles increased by 11.1%, from 91.95 Nm to 102.12 Nm (p = 0.0469).
   • Right knee flexor strength improved by 8.5%, from 97.45 Nm to 105.74 Nm (p = 0.0367).

2. Increased Muscle Size:

   • Thigh circumference (10 cm above the patella) increased by 1.9% on the left leg, from 51.10 cm to 52.05 cm (p = 0.0357).
   • Circumference at 20 cm above the patella showed a 1.5% increase, from 59.50 cm to 60.40 cm (p = 0.0423).

3. Efficiency and Accessibility:

   • The EMS group achieved these results with minimal joint strain, making it suitable for individuals recovering from injury or with mobility challenges.

Why EMS Could Be Helpful for You

EMS activates a larger number of muscle fibers than traditional exercise alone, leading to:

• Faster strength gains.
• Improved muscle symmetry, particularly in weaker limbs.
• Low-impact training, perfect for people recovering from injuries or surgery.

How This Study Helps EMS Device Users

For those using EMS devices like ORIEMS FIT:

• Incorporate EMS sessions with light exercises for better results.
• Focus on weaker muscle groups to enhance balance and strength.
• Enjoy the convenience of EMS for maintaining fitness with less effort.
