Eccentric Cycling as Training Modality
Investigating acute and chronic adaptations to eccentric cycling as a unique training modality to improve strength and performance.
Overview
Eccentric muscle contractions—where muscles lengthen under load—offer a unique physiological stimulus compared to traditional concentric exercise. This project investigates eccentric cycling as a novel training modality, allowing for high mechanical work rates with reduced metabolic cost.
We are studying both the acute physiological responses (what happens during a single session) and chronic adaptations (how the body changes over weeks of training). This research has implications for elite performance, injury rehabilitation, and clinical populations who may benefit from high-force, low-energy-cost exercise.
Objectives
- Characterize acute physiological responses
- Measure chronic training adaptations
- Evaluate applications for rehabilitation
Methodology
- Advanced cycle ergometers capable of eccentric loading
- Electromyography (EMG) to measure muscle activation
- Indirect calorimetry for metabolic energy expenditure
- Muscle biopsies to analyze cellular adaptations (in collaboration with partners)
- Performance testing (strength, power, endurance)
