The leading hypothesis for delayed onset muscle soreness is are?

The leading hypothesis for delayed onset muscle soreness (DOMS) is that it results from microtrauma to muscle fibers and connective tissues during intense or unfamiliar exercise. This damage triggers an inflammatory response, leading to swelling and pain in the affected muscles. Additionally, the accumulation of metabolic byproducts, such as lactic acid, may contribute to the sensation of soreness. Overall, DOMS is believed to be a complex interplay of mechanical damage and the body's healing response.
