how do you calculate the cals needed per day?

1. take relative VO2 to absolute (multiply VO2 by bodyweight) 2. convert mL to L (times .001) 3. convert L to cal ( times by 5) 4. need calories per hour (multiply by 60) 5. need calories per day (times 24)

parts of a graph showing VO2

rest, O2 deficit, steady state, EPOC

(O2 currently consuming vs what need @ steady state) 1. represents dif score (need VO2 of 30 to sustain exercise. currently consuming 15 mL/kg/min. still need 30. 30-15-15. 15 is the dif score). 2. represents anaerobic contribution

steady state ATP for long term exercise

(takes 1-4 mins to get) flat part of graph. demand is being met -sustainable over time (except in heat or supr high intensities) O2 demand & HR is stable. -anaerobic energy production makes up the dif from the dif score in O2 deficit = steady state

(excess, post-exercise, oxygen, consumption) -recovery, repaying O2 deficit -excess O2 uptake above rest following exercise -how much extra O2 are we consuming post-exercise? -duration and intensity driven -could last 12-24 hours

rapid portion- steep decline in O2 uptake following exercise. 2-3 mins post exercise (HR and respiration rate slowing down) slow portion- slow decline in O2 uptake following exercise. 30+ mins post exercise (resting VO2 going down).

EPOC= lactic acid clearance

70% LA = oxidized- used as fuel by heart& skeleton 20% converted to glucose (gluconeogenesis = lactic acid-> glucose) 10% converted to amino acids light aerobic activity (a cooldown) will expedite lactic acid clearance process

what else happens during EPOC

lactate conversion to glucose restoration of blood O2 stores elevate body temp post-exercise elevation of HR and breathing (2-3 mins, rapid portion) -elevated hormones

Question	Answer
at rest what's the mL of O2 needed for the average person	3.5mL/kg/min
how many calories are in 1L of O2	5kcals

O2 deficit	(O2 currently consuming vs what need @ steady state) 1. represents dif score (need VO2 of 30 to sustain exercise. currently consuming 15 mL/kg/min. still need 30. 30-15-15. 15 is the dif score). 2. represents anaerobic contribution

EPOC	(excess, post-exercise, oxygen, consumption) -recovery, repaying O2 deficit -excess O2 uptake above rest following exercise -how much extra O2 are we consuming post-exercise? -duration and intensity driven -could last 12-24 hours
2 portions of EPOC	rapid portion- steep decline in O2 uptake following exercise. 2-3 mins post exercise (HR and respiration rate slowing down) slow portion- slow decline in O2 uptake following exercise. 30+ mins post exercise (resting VO2 going down).
EPOC= lactic acid clearance	70% LA = oxidized- used as fuel by heart& skeleton 20% converted to glucose (gluconeogenesis = lactic acid-> glucose) 10% converted to amino acids light aerobic activity (a cooldown) will expedite lactic acid clearance process
