Glycogen is one of the primary replenishments after exercise. Glycogen is considered essential to training at levels needed for muscle hypertrophy, responsible for as much as 80% of ATP production during workouts. [2] Due to such involvement of glycogen in the body during training, it is suggested that we replenish these levels after training.
After this type of exercise, there is a need to refill glycogen storage sites in the body (the long simple sugar chains in the body that store energy), although they are not likely fully depleted. To compensate for this glycogen reduction, athletes will often take in large amounts of carbohydrates, immediately following their exercise.
Unless glycogen stores are replenished during exercise, glycogen stores in such an individual will be depleted after less than 2 hours of continuous cycling [11] or 15 miles (24 km) of running. Training and carbohydrate loading can raise these reserves as high as 880 g (3600 kcal), correspondingly raising the potential for uninterrupted exercise.
Glycogen (black granules) in spermatozoa of a flatworm; transmission electron microscopy, scale: 0.3 μm. Glycogen is a multibranched polysaccharide of glucose that serves as a form of energy storage in animals, [2] fungi, and bacteria. [3] It is the main storage form of glucose in the human body.
The hypothesis was put forward in 2012 [1] and Benton, et al. named the cycle in 2017 after its inventor, the Swiss biochemist, nutritionist and exercise physiologist Dr. Serge Summermatter. [8] The concept of the Summermatter cycle finds broad application in body weight management to time exercise interventions and avoid catch-up fat (yo-yo ...

In all athletic programs, three features should be present: (1) emphasizing prolonged lower-intensity exercise, as opposed to repetitive max intensity exercises; (2) adequate rest periods and a high-carbohydrate diet, to replenish glycogen stores; and (3) proper hydration, to enhance renal clearance of myoglobin. [18]
After five minutes of exercise, the O 2 system is dominant. In a 1 km run, this system is already providing approximately half the energy; in a marathon run it provides 98% or more. [ 6 ] Around mile 20 of a marathon, runners typically "hit the wall," having depleted their glycogen reserves they then attain "second wind" which is entirely ...
