Cardiorespiratory
the ability of the heart and lungs to deliver oxygen rich blood to the muscles as well as how well the muscles utilize the oxygen in order to produce and utilize energy cardiovascular/aerobic TERM 2
Four ways to measure Cardiorespiratory
Fitness
DEFINITION 2 VO2 max resting and recovery heart rate performance times or time to exhaustion Recovery VO TERM 3
Two ways to express Cardiorespiratory
Fitness
DEFINITION 3 Relative VO2 max Absolute VO2 max - measure oxygen in L/min Metabolic Equivalence - MET TERM 4
1 MET =? 1 lb =
DEFINITION 4 3.5 ml/kg/min 2.2 kg TERM 5
A 150 lb male has a VO2 max of 4 L/min.
What is his relative VO2 max?
DEFINITION 5 Turn lbs into kg: 150 / 2.2 = 68.18 kg Turn L/min into mL/min: 4 L/min x 1000 = 4000 mL/min Divide mL by kg: 4000 mL / 68.18 kg = 58.67 mL/kg/min
What is the relative VO2 max in
METs?
58.67 ml/kg/min / 3.5 ml/kg/min = 16.76 METs TERM 7
A 120lb female wants to exercise at a level of
15 METs. What will her absolute VO2 max be?
DEFINITION 7 Turn lbs to kg: 120/2.2 = 54.55 kg Turn METs to ml/kg/min: 15 METS x 3.5 = 52.5 ml/kg/min Multiply to get ml/min: 54.55 kg x 52.5 ml/kg/min = 2864ml/min turn ml/min to L/min: 2864/1000 = 2.87 L/min TERM 8
