cardiorespiratory training concepts and strategies Flashcards
energy expenditure of ____kcal per day is needed for CRF improvements associated with health and disease prevention
200-400
energy expenditure is the
relationship between calories and aerobic work stems from the oxidation value of energy
___kcal of energy is released per liter of oxygen used
5
if we know the total quantity oxygen used, we know the
calories expended during any type of daily activity or training
common method for conveying the energy demands of work
METs
rest= ___MET
1
the energy needed for resting metabolic homeostasis
MET values above rest represents
the amount of oxygen to support work
MET calculation:
running on a treadmill at 10 METs
3.5 (rest) x 10 =35 ml/kg/min
MET calculation:
220lb (100 kg) man sitting in a chair for 60 mins
3.5 (100kg) =350
350 x 60min = 21,000
21000 x .001 L= 21L
21L x 5 kcal= 105kcal
MET calculations using body weight exercises for relative caloric expenditure requires
body weight in kg and the duration in minutes the activity was performed
example behaviors that lower calorie expenditure below displayed value on machines
leaning on weight bearing machine
holding onto rails
failing to comply with default RPMs
estimating a clients VO2 max via proper assessment allows for the attainment of
MET-max and MET training zone for use while training on machines that calculate METs
aerobic exercise aimed at improving CRF can include numerous systems and forms; the key factors are
duration, intensities, frequency, and energy expended per session
common training systems include
lactate threshold training
tempo training
cross training
cardio circuits
fartlek training
lactate threshold/tempo training
conditioned individuals use this technique for improvements in stamina and lactate tolerance
