Muscle power Your Muscles get most of energy that powers them by combining glucose with oxygen. This happens in a biochemical process called aerobic (oxygen-based) respiration, which takes place within the muscle cells. The glucose comes from the food you eat and the oxygen from the air you breathe, and your bloodstream delivers these to your muscles and other cells in your body. Energy and exercise When you work your muscles hard, for example when you are exercising, they need a lot more energy than they do when you are resting. Your heart then bets fasted and your lungs work harder to keep them supplied with glucose and oxygen. Sometimes, however, your bloodstream cant supply all the oxygen and glucose that your muscles need, no matter how hard your heart and lungs are working. This can happen during high intensity exercise such as sprinting or uphill cycling. To make up for this shortfall, your muscles get the extra energy they need by drawing on their own reserves of glucose. These reserves take the form of a substance called glycogen, which your muscles and liver. Your muscles can rapidly change this glycogen back into glucose, then produce energy from it process called anaerobic (oxygen free)respiration. Anaerobic respiration provides your muscles with a valuable energy boost, but it doesn’t last very long. Fatigue soon sets in when the glycogen runs out and lactic acid a by product of anaerobic respiration builds up in your muscles need and remove the lactic acid from them. #MusclePower #AerobicRespiration #AnaerobicRespiration #MuscleEnergy #ExerciseScience #SportsInjuryCare #OrthopaedicHospital #AshwiniHospital #HealthyMuscles #NashikDoctors
