Muscle Vs Exercise

Over the course of the last 100 years, the lifestyles of humans have seen drastic changes. This has ultimately led to less exercise as everything has become much easier to obtain, especially things like food. All of this has led to the majority of our population becoming obese while also causing our muscles to become less productive. It is common knowledge that the more you use your muscles, the stronger they become. It also works the other way around. The less you use your muscles, the weaker they become. Muscle fibers will adapt to the type of exercise that you put them through, aerobic or anaerobic. When muscles are used, they are getting stronger. Because of this, it is my hypothesis that skeletal muscle fibers will adapt and become stronger …show more content…
One such benefit is the prevention of disorders brought on by excessive weight, such as diabetes. By exercising their muscles, an individual reduces glycogen stores in the muscles, allowing for: glycogen to be stored as muscle glycogen, the resistance of fat accumulation, and the storage for healthy carbohydrates after meals, helping prevent type II diabetes (Jenson, Rustad, Kolnes, Lai, Abstract Section, para. 1). These individuals also burn more fat during workout instead of glycogen. By exercising their muscles continuously and more frequently, these individuals’ muscles begin to burn fats during workouts and sparing the glycogen, in a process known simply as the glycogen-sparing effect. Thus, well trained individuals lose excess body fats during their workouts. Also, because an individual is burning fats during their workout, they are also getting the most energy as well. Fats have the most calories per gram with a total of nine calories per gram (Paula, Energize Me Section, para. 1). This means that an individual is providing their muscles with the most energy by sparing their glycogen and burning their fat. This process of burning these fatty acids in order to provide an individual with energy is done through the process known as beta-oxidation (Beta Oxidation: Definition and Steps, What is Beta-Oxidation? Section, para. 3). Beta oxidation is the initial phase of fatty acid oxidation (Marieb & Hoehn, p. 934). The muscles of those who are not well trained, or perhaps just started to exercise, will obtain their energy from glucose, which comes from the breaking down of glycogen in a process known as glycogenolysis (Glycogenolysis In Muscle and Liver, Glycogenolysis: definition, steps, and functions Section, para. 6). While this doesn’t provide the most energy to the muscles, it still provides enough for the individual to start exercising until the body switches from
