Despite how it sounds,eccentric exercise does not involve going for a run in a silly costume says Professor Nosaka.
“Eccentric exercise is where load is placed on the muscle while it is lengthening, rather than shortening," he said.
"For example, walking down stairs is eccentric exercise because your front thigh muscles are lengthening when they are placed under load, as opposed to walking up stairs in which the muscles are shortening, performing mainly concentric contractions.”
Professor Nosaka said there was a growing body of evidence that the health benefits of eccentric exercise were greater than from concentric exercise.
