Study Notes
Basal Metabolic Rate (BMR)
- Minimum energy required for survival at complete rest.
- Influenced by factors such as:
- Muscle mass: More muscle mass requires more energy.
- Hormones: Growth hormone, testosterone, and thyroxine increase BMR.
- Fever: Increases BMR.
- Sleep: Decreases BMR.
- Malnutrition: Decreases BMR due to the body becoming more "efficient" in energy use.
- Sex and age: Females and older individuals generally have lower BMRs, influenced by factors like muscle mass and adipose tissue differences and sex hormone variations.
Heat Production in the Body
- Approximately one-third of energy released from ATP hydrolysis is converted to heat.
- Microscopic friction also generates heat through:
- Blood flow.
- Movement within the musculoskeletal system.
Oral Temperature Ranges
- Resting: 97 to 99.5°F (approximately).
- Exercise: 101 to 104°F (approximately).
- Cold: (Temperature range not specified)
Rectal Temperature
- Rectal temperature is typically higher than oral temperature.
