Mondo Knows Facts
Muscle soreness peaks a day or two after effort
Unfamiliar or downhill exercise damages fibres and the ache arrives many hours later Eccentric actions, where a muscle lengthens under load, strain the sarcomeres unevenly and leave small disruptions. Soreness usually builds over the next 24 to 72 hours as repair and inflammation proceed. The discomfort fades on its own, and the same exercise repeated causes much less damage. It sits in Mondo's human body collection, one of 200 facts that each trace back to the reference below.
