[22] Bioenergetics in Exercise Science Flashcards
What is the relevance of studying bioenergetics in exercise science?
It helps understand how energy production and use change during physical activity.
How does exercise affect energy production?
Exercise increases energy production to meet the increased energy demand.
How does the body adapt its energy use during exercise?
The body ramps up energy use during exercise to fuel the working muscles.
What is the impact of increased energy production during exercise?
It provides the necessary energy to support physical activity, helping improve performance.
What is the role of carbohydrates in energy production during exercise?
Carbohydrates are broken down into glucose, a primary energy source during high-intensity exercise.
How do fats contribute to energy production during exercise?
Fats are a major energy source during low to moderate intensity exercise.
What role does protein play in energy production during exercise?
Protein contributes minimally to energy production but is vital for muscle repair and growth post-exercise.
How do energy needs change during high-intensity vs low-intensity exercise?
High-intensity exercise relies more on carbohydrates for energy, while low-intensity exercise utilizes more fats.
How does exercise duration impact energy use?
Longer exercise sessions increase overall energy use and can shift the body to utilize more fats for energy.
How does the body meet increased energy demands during exercise?
The body ramps up energy production, mainly by increasing carbohydrate and fat metabolism.
What energy systems are used during exercise?
The body uses the phosphagen system, glycolysis, and the aerobic system, depending on exercise intensity and duration.
How does the phosphagen system contribute to energy production during exercise?
The phosphagen system provides quick energy for short, high-intensity bursts of activity, primarily through ATP and creatine phosphate.
What is the role of glycolysis in energy production during exercise?
Glycolysis breaks down glucose for energy, supporting sustained high-intensity exercise.
How does the aerobic system contribute to energy production during exercise?
The aerobic system uses oxygen to produce energy from carbohydrates, fats, and protein, supporting longer, low-intensity exercise.
What changes occur in bioenergetics during recovery from exercise?
Energy production slows and shifts towards replenishing energy stores and repairing and building tissues.
