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
Neeraj Mehta task. A person with more muscle should be more flexible than one who is having less muscle mass. The human body muscle can stretch up to 30% of their length, but the connective tissues that can stretch up to just 4-5%. While lifting weights, and doing repetitions, one usually applies a lot of pressure on the connective tissues and the joints, leading to stiffness or strains causing injury. Exercise should keep in mind proper alignment of muscles and joints, and the availability of oxygen for the right effect, like four wheels of a car that need to be aligned well
