B4. Exercise and Respiration. Define VO2 and VO2max. VO2 – An expression of the rate at which oxygen is used by tissues, usually given in microliters of oxygen consumed in 1 min by 1 milligram dry weight of tissue.
Exercise and Respiration
Creatine phosphate + ADP creatine + ADP
CP found in muscle fibers but only in conc that allows for 8-10 secs of ATP production during vigorous exercise
Supplementation attempts to increase [ CP ] in muscles = performance during high intensity exercise
Sig. increases only occurs in individs with low [ CP ] tp begin with
Appears more likley gain in water retention that CP levels which = decrease in athletic performance
The following table, adapted from O'Neil (2001), shows the relationship between exercise I
ntensity (% of your Maximum Heart Rate) and the energy source (carbohydrate and fat).
State that lactate produced by anaerobic cell respiration is passed to the liver for processing and creates an oxygen debt
