What are the normal ranges of VO2 max for men and women?
The norms for relative maximal oxygen uptake will vary depending on the age and gender of the individual. For a male between the ages of 18-25, the ranges for relative maximal oxygen uptake would be, very poor < 30(ml/kg/min), average 42-46(ml/kg/min) and excellent >60(ml/kg/min). For a female between the ages of 18-25, the ranges for relative maximal oxygen uptake would be, very poor < 28(ml/kg/min), average 38-41(ml/kg/min) and excellent >56(ml/kg/min). In comparison, the relative maximal oxygen uptake for a male between the ages of 56-65 would be, very poor < 20(ml/kg/min), average 26-28(ml/kg/min) and excellent >37(ml/kg/min). What causes abdominal cramps when we run? Most physiologists agree that moderate to intense exercise affect intestinal absorption and blood flow to the gut. Since substances must be absorbed from the intestinal wall into the blood, reductions in blood flow suggest fewer opportunities for absorption. Abdominal cramping is an indication of an interruption in ox
