Скачать или смотреть Lactic Acid Does NOT Cause Muscle Fatigue.

This video first discusses the history of lactic acid and muscle fatigue. It then explains the basic anatomy of muscle and how muscle fibers use ATP to contract. Next it explains how ATP can be made by fibers through the breakdown of glucose (glycolysis) and the role that oxygen plays in that process. It then discusses how muscle fibers consume lots of ATP during sprints and how glycolysis is used to try and make lots of ATP quickly for the fibers. It then discusses how insufficient oxygen forces the fiber to run anaerobic glycolysis and produce lactic acid which was believed to cause fatigue. Next it explains how lactic acid does not cause fatigue and how muscle fibers do not even make lactic acid. It finishes by discusses what might cause muscles to fatigue.
