, positive energy balance - CORRECT ANSWERS-more calories consumed than
expended
negative energy balance - CORRECT ANSWERS-fewer calories consumed than
expended
hyperplasia - CORRECT ANSWERS-increase in number of cells (e.g., fat cells in
childhood, pregnancy)
hypertrophy - CORRECT ANSWERS-increase in cell size (low growth and
maintenance, such as throughout adulthood)
basal metabolic rate - CORRECT ANSWERS-the number of calories used by the body
while in a fasting state
accounts for approximately 60-70% of energy expenditure
males 1kcal/kg/hr, femals 0.9kcal/kg/hr
BMR Effectors - CORRECT ANSWERS-gender, lean body mass, body size,
temperature, age, nervous system activity, levels of caffeine intake, and tobacco use
age and BMR - CORRECT ANSWERS-declines by 1-2% per decade
Thermic effect of food (TEF) - CORRECT ANSWERS-energy used for digestion and
absorption of food and accounts for approximately 10% of the calories expended
Thermogenesis - CORRECT ANSWERS-ability to regulate body temperature and
activities such as fidgeting, maintaining body posture, and shivering
small expenditure
brown fat - CORRECT ANSWERS-found in infants below the collar bone
metabolizes the energy yielding nutrients, which results in heat production to be used by
the body
more brown fat in lean adults
physical activity - CORRECT ANSWERS-15-40% of energy expenditure
direct calorimetry - CORRECT ANSWERS-measures the amount of heat given off by
the body
insulated chamber surrounded by a thin layer of water is used to measure the amount of
heat emitted by the subject in the chamber
indirect calorimetry - CORRECT ANSWERS-uses oxygen intake and carbon dioxide
output, along with scientific formulas, to measure energy expended
expended
