Whole-Body Electromyostimulation Improves Performance-Related Parameters in Runners

Area of Science:

• Exercise Physiology
• Sports Science
• Rehabilitation

Background:

• Recreational runners often seek methods to enhance performance while managing training load.
• Whole-body electromyostimulation (WB-EMS) is a training modality that simultaneously stimulates major muscle groups.
• The efficacy of WB-EMS in improving physiological and performance parameters in endurance athletes with reduced training volume requires further investigation.

Purpose of the Study:

• To investigate the effects of a 6-week WB-EMS intervention on maximal oxygen uptake (VO2max), aerobic and gas exchange thresholds, running economy, and muscular power in male recreational runners.
• To compare the performance outcomes between a group undergoing WB-EMS training with reduced running frequency and a control group maintaining usual training.

Main Methods:

• Twelve male recreational runners were randomized into either a WB-EMS intervention group (n=6) or a control group (n=6).
• The WB-EMS group reduced running frequency to once weekly and performed one weekly WB-EMS session for 6 weeks.
• Assessments included VO2max, aerobic and gas exchange thresholds, running economy, and vertical jump, conducted at baseline and post-intervention.

Main Results:

• The WB-EMS group demonstrated significant improvements in VO2max, aerobic and gas exchange thresholds compared to the control group.
• Improvements in running economy and vertical jump performance were also observed in the WB-EMS group post-intervention.
• These enhancements occurred despite a reduction in overall running training volume for the WB-EMS participants.

Conclusions:

• WB-EMS appears to be an effective training strategy for enhancing aerobic capacity, metabolic thresholds, and muscular power in male recreational runners.
• This modality can facilitate performance improvements even when traditional endurance training volume is decreased.
• WB-EMS may serve as a valuable complementary or alternative training method for runners aiming to optimize performance and manage training load.
