In biology, basal rate is a rate of continuous supply of some chemical or process. In the case of diabetes mellitus, it is a low rate of insulin supply needed for such purposes as controlling cellular glucose and amino acid uptake. An insulin pump is one way to arrange for a closely controlled basal insulin rate. The constant release insulins (e.g, Glargine) can provide a similar effect.
Basal metabolic rate increases with the amount of muscle tissue a person has, and it reduces with age.
The target heart rate during physical activity should be 60 to 90% of the maximum heart rate.
Physical activity contributes to health by reducing the heart rate, decreasing the risk for cardiovascular disease, and reducing the amount of bone loss that is associated with age and osteoporosis.
Basal metabolic rate (BMR), is the rate of metabolism when an individual is at rest in a warm environment and is in the post absorptive state, and has not eaten for at least 12 hours.
Basal metabolic rate is measured under very restrictive circumstances.
A more common and closely related term used in many cases is resting metabolic rate (RMR), which is measured under less strict conditions.
