Moderate Load Eccentric Exercise; A Distinct Novel Training Modality.

Area of Science:

• Exercise Physiology
• Rehabilitation Science

Background:

• Progressive eccentric exercise protocols have been studied for two decades.
• These protocols utilize controlled eccentric loads via specialized equipment.
• Training ramps loads over three weeks to prevent muscle damage and soreness.

Approach:

• Moderate load eccentric exercise (RENEW) involves controlled eccentric loading, distinct from plyometrics or eccentric overload training.
• Training sessions are typically 20-30 minutes, three times weekly.
• Loads reach 400-500 W in rehabilitation and over 1200 W for elite athletes.

Key Points:

• RENEW is as effective as conventional strength training for increasing muscle strength and volume.
• It reduces joint loads due to higher angular velocities.
• Energy requirements are significantly lower (4-fold) compared to concentric exercise.

Conclusions:

• Moderate load eccentric exercise is a preferred tool for conditions with impaired muscle energy supply.
• Effectiveness is demonstrated in cardiorespiratory issues, sarcopenia, diabetes, cancer, and neurological conditions.
• It is also beneficial for locomotor system injury prevention and rehabilitation, including ACL surgery recovery.
