There is an interesting article in NY Times.
Just as there is an increasing body of evidence that physiological & pharmacological considerations are very different depending on who you are (examples include different blood pressure treatments or Hb A1c levels by race and variations in heart disease presentation and treatment by gender), it seems - not surprisingly - that physiological differences also account for differences during exercise between men and women.
Most studies on exercise physiology have been done only w/ male subjects. This article discusses how when a study was done w/ women subjects the results were totally different.
I bring this to folks' attention because I think women who train should be aware research findings may not apply to us... read published studies carefully.
