Guys, especially teenagers, go crazy over muscle building and try following any advice that comes their way. An often-quoted one includes that, lifting weights breaks down a muscle which then grows stronger or bigger during the repair process. But, is this another myth or a reality?
Over-training to the point of fatigue definitely causes muscle damage, especially to the proteins that comprise muscle fiber. Two types of overload namely, metabolic and mechanical, can stimulate muscle growth. Metabolic overload is the quantity of work done by a muscle that depletes it of its energy supply. Mechanical overload primarily leads to structural damage of the actin-myosin protein filaments due to intense exercises such as weightlifting. The damage to the muscle causes the protein to synthesize new cells that are used to repair the damaged protein fiber.
