Ex Rx for Fat Loss - Equations

what is a MET

1 MET = VO2 associated w sitting at rest = 3.5 mL/kg/min 2

are METS useful way to describe intensity (4)

YES

• simple for general public

• METs are provided on most cardio equip

• easy to calculate

• physicians (usually) understand what it means to exercise at 4 METs

are METS useful way to describe intensity - cons (3)

• assumes resting VO2 for all people is 3.5

• absolute measure that does not take into account individ VO2

• doesn’t take into account env’t conditions

weight loss program design steps (3)

• determine total fat loss goal for initial phase of PA program (5%)

• choose weekly fat loss rate of 1-2 lbs/week

  • 1 lb of fat = 3500 kcal

• plan program ensuring 1000-2000 kcal /wk is expended through PA

plan PA program around weekly target (5)

• discuss activities client enjoys or might enjoy

• consider fitness assessment results AND client’s history of PA

• consult table w MET values for chosen activities/intensities

• calculate EE per activity and ensure that it roughly equals (± 50 kcal)

• make sure to educate client on reducing sed time and inc light PA
