Glycolysis involved in glycolysis. The burning sensation in muscles during hard exercise can be attributed to the release of hydrogen ions during the shift to glucose fermentation from glucose oxidation to carbon dioxide and water, when aerobic metabolism can no longer keep pace with the energy demands of the muscles. These hydrogen ions form a part of lactic acid. The body falls back on this less efficient but faster method of producing ATP under low oxygen conditions. This is thought to have been the primary means of energy production in earlier organisms before oxygen reached high concentrations in the atmosphere between
Form (exercise) Form (exercise) Form is a specific way of performing a movement, often a strength training exercise, to avoid injury, prevent cheating and increase strength. Exercises or drills in sport have a recognized way of performing the movements that have two purposes: By using proper or 'good and' form, the risk of injury is lowered. A lack of proper form commonly results in injury or a lack of effect from the exercise being performed Good form ensures that the movement only uses the main muscles, and avoids recruiting secondary muscles. As a muscle fatigues, the body attempts to compensate by recruiting
