Implementing Eccentric Resistance Training-Part 1: A Brief Review of Existing Methods

Area of Science:

• Exercise Physiology
• Sports Science
• Biomechanics

Background:

• Eccentric training involves muscle lengthening under load, a crucial component often underutilized in traditional training.
• Understanding the physiological adaptations to eccentric exercise is key for optimizing performance and hypertrophy.

Purpose of the Study:

• To establish a physiological rationale for incorporating eccentric resistance training.
• To review common eccentric training methodologies and their application.

Main Methods:

• Literature review of physiological adaptations to eccentric training.
• Overview of commonly prescribed eccentric training methods: tempo eccentric, flywheel inertial, accentuated eccentric loading, and plyometric training.

Main Results:

• Eccentric training demonstrates significant potential for increasing muscle cross-sectional area, force output, and fiber shortening velocities.
• Different eccentric training methods (tempo, flywheel, accentuated eccentric, plyometric) overload the muscle differently during lengthening actions.
• The specific constraints and implementation of these methods influence force absorption and the resulting adaptive response.

Conclusions:

• Eccentric resistance training provides a robust physiological foundation for improving muscle size, strength, and power.
• The diverse eccentric training methods offer versatile applications for inducing beneficial adaptations across various populations.
• Tailoring training constraints is crucial for maximizing the adaptive benefits of specific eccentric training modalities.
