2
Oxygen Consumption

• Amount of Oxygen taken up by the body for
  metabolism
• VO2
• O2 in O2 out

3
Maximal Rate of Oxygen Consumption

• VO2 max
• Max amount of oxygen taken up and used by the
  body for metabolism
• VO2 max reflects the bodys ability to transport
  and utilize oxygen
• is our best estimate of cardiovascular fitness
  (aerobic fitness)

4
Respiratory Exchange Ratio (RER)

• ratio of carbon dioxide output/volume of oxygen
  consumed (VCO2/VO2)
• technique used to estimate contribution of CHO
  or FAT to energy metabolism during exercise
• using CHOs results in RER 1.0
• using FATS as energy source results in RER 0.7

5
Ventilatory Threshold

• Breakpoint when pulmonary ventilation and
  carbon dioxide output begin to increase
  exponentially during an incremental exercise test
  

6
Lactic Acid

• Causes ventilatory threshold
• Used as a marker increased anaerobic metabolic
  system being used

7
Lactate Threshold

• Point at which lactic acid rises exponentially

8
OBLA

• Point where lactic acid begins to accumulate
• Offset with training (interval)
• in an untrained individual, onset of blood
  lactate would occur around 50-60 of VO2 max
• in a trained individual, the onset of blood
  lactate would occur around 70-80 VO2 max

9
Oxygen Deficit

• Difference between O2 required to perform a task
  and the O2 actually consumed
• Prior to steady state
• Reason for feeling ugh at start of exercise or
  at tough points during

10
EPOC

• Reason you huff and puff after exercise
• 5 reasons for this
• Replenish O2 in blood and tissue
• Replenish creatine (PC)
• Decrease heart rate and respiration rate
• Decrease body temperature
• Increase blood lactic acid removal
