Final answer:
The kcals remaining for other body functions after exercise training are part of the resting metabolic rate (BMR), which accounts for approximately 70% of total daily energy expenditure for maintaining basic bodily functions.
Step-by-step explanation:
The amount of kcals remaining for other body functions after exercise training is referred to as the resting metabolic rate (BMR). BMR describes the daily energy expenditure of humans at rest and is crucial for maintaining basic, daily activities. About 70 percent of a person's daily energy expenditure is due to the basic functions of organs, with an additional 20 percent from physical activity and the remaining 10 percent for body thermoregulation. Athletes often have a higher BMR because of increased lean muscle mass, which burns more calories.
For example, if we were to consider the claim by manufacturers of an exercise bicycle that you can metabolize 0.500 kg of body fat per day by exercising for 2 hours, where body fat is metabolized supplying 9.30 kcal/g, it would involve calculating the total energy output and examining the feasibility of such a claim. However, it's crucial to understand the basic premise behind energy expenditures and BMR to assess whether such claims or exercise regimens are reasonable.
