For the first 45 minutes its glycogen, then body fat for the next 45 minutes. If you train for more than 90 minutes you begin to burn muscle and fat.

An example of anaerobic exercise is weightlifting or sprinting, which involves short bursts of intense activity that do not rely on oxygen for energy production.
During intense exercise, the majority of blood is allocated to the muscles to provide them with oxygen and nutrients needed for energy production.
The main store of energy is in the adipose tissue (body fat), with some also being stored in glycogen stores, for bursts of intense exercise.
During extended exercises such as distance running, both anaerobic and aerobic energy pathways are utilized. Anaerobic pathways are primarily used during the beginning of the exercise or during bursts of intense activity, while aerobic pathways become the predominant source of energy as the exercise continues and oxygen availability increases. The transition from anaerobic to aerobic energy production helps to sustain energy output over longer durations of exercise.
During exercise, the body primarily uses two pathways to release energy: the aerobic pathway, which requires oxygen and is more sustainable for longer durations of exercise, and the anaerobic pathway, which does not require oxygen and is used for short bursts of intense activity. Each pathway produces energy in the form of adenosine triphosphate (ATP) to fuel muscle contractions.
Creatine phosphate serves as a quick source of energy by rapidly regenerating ATP, the primary energy currency in cells. This helps to sustain high-intensity physical activities by providing additional energy during short bursts of intense exercise, such as weightlifting or sprinting.
Aerobic exercise involves using oxygen to produce energy for sustained physical activity, while anaerobic exercise does not require oxygen and relies on stored energy sources for short bursts of intense activity. Aerobic exercise is more efficient at producing energy over longer periods of time, while anaerobic exercise is better suited for quick, high-intensity efforts.
Anaerobic exercise is a type of physical activity that does not require oxygen for energy production. It typically involves short bursts of high-intensity movements, such as weightlifting or sprinting. In contrast, aerobic exercise relies on oxygen to fuel the body during longer, moderate-intensity activities like running or cycling. The main difference between the two is the way the body produces energy, with anaerobic exercise being more intense but shorter in duration compared to aerobic exercise.
Anaerobic refers to a process that occurs without the need for oxygen. In the context of exercise, anaerobic activities are short, intense bursts of physical exertion that do not rely on oxygen to generate energy. Examples include sprinting and weightlifting.
During intense physical activity, human muscle cells use lactic acid fermentation to produce energy when there is not enough oxygen available. This process converts glucose into lactic acid, releasing energy that can be used by the muscles for short bursts of activity.
Muscle cells can respire anaerobically during intense exercise when there is not enough oxygen available to meet the demands for energy. This leads to the production of lactic acid as a byproduct. Anaerobic respiration helps provide quick bursts of energy when oxygen is limited, but it is less efficient than aerobic respiration.
