Boosting Fitness Up To 35%: EMS Exercise Improves Aerobic Capacity and Muscle Strength

Study Title: Prolonged Electrical Muscle Stimulation Exercise Improves Strength and Aerobic Capacity in Healthy Sedentary Adults

This study explored the impact of prolonged electrical muscle stimulation (EMS) on sedentary adults' physical fitness. Fifteen participants underwent a 6-week EMS training program, involving 29 one-hour sessions. The EMS induced rhythmic leg muscle contractions without joint loading, simulating cardiovascular exercise. The study found significant improvements in peak aerobic capacity, walking distance, and quadriceps strength after training. However, it did not significantly affect body mass index (BMI).

These results suggest that EMS can enhance physical fitness in sedentary adults, potentially serving as an alternative to traditional exercise methods.

Check out more specific key findings below: 

  • Prolonged electrical muscle stimulation (EMS) training significantly improved physical fitness among sedentary adults. Peak aerobic capacity (VO2) increased by approximately 10% (0.24 out of 2.46 liters per minute), indicating enhanced cardiovascular fitness.
  • The study also showed a substantial increase in muscle strength. Quadriceps strength improved by about 24%, with an average gain of 87.5 Newtons. This suggests that EMS can effectively enhance muscle function.
