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
Exercise and music various muscles. Thomas Hans Fritz, a researcher at the Max Planck Institute who led the study said, “Participants could express themselves on the machines by, for instance, modulating rhythms and creating melodies.” Throughout each workout, the researchers monitored the force their volunteers generated while using the machines, as well as whether the weight lifters’ movements tended to stutter or flow and how much oxygen the volunteers consumed, a reliable measure of physical effort. Afterward, the scientists asked the volunteers to rate the tolerability or unpleasantness of the session, on a scale from 1 to 20. Exercise and music The interplay
