This article compares the metabolic and physiological effects of concentric and eccentric endurance exercise tests involving the ankle and knee. Findings indicate that the eccentric exercise tests result in lower ammonia and lactate reactions, reduced fatigue, and less metabolic stress than comparable concentric exercise tests.
