Hello Carl, Average untrained men and women (non-athletes) will typically have VO2 max values of about 45 and 35 ml/kg body weight, and the highest values in trained athletes are on the order of 90 and 80 ml/kg body weight (for males and females, respectively). If an average non -athletic person (45 to 35 ml/kg) were to drastically increase their body weight from the average weight, you can see how this would place their VO2 max at very low levels, and that gas exchange would not occurr as predicted for "average divers". However, as you can see from the training values, you could increase your VO2 max through training, and even with high body weight a person may attain levels not significantly below average, if the body weight is not too far above average. Realistic goals for people with NO real aerobic conditioning (a great many scuba divers!!!) would be an increase of approximately 20% for their VO2 max after a period of several months of quality aerobic training (cycling;running;x-country skiing; skating, etc., if each is performed for an optimal 1 to 2 hours a day for 4 to 5 days per week). And don't let any one in a Scandanavian Health Spa sell you on a 20 minute, three time per week circuit at their gym...its bullshit. It takes 20 minutes for your aerobic/enzyme system just to turn on, lot less to train it. Hope this helps, Dan P.S.
