Vaguely health and fitness-related. Can someone explain for dummies what this sentence means?
[Typical is] a reduction in maximal whole-body oxygen consumption (Vo2max) demonstrated by a characteristic deficit in peripheral oxygen extraction (arteriovenous O2 difference) and an enhanced oxygen delivery (hyperkinetic circulation)
Does the first part of this sentence mean that the body needs less oxygen or doesn't take up as much as needed? Or something completely different? Would you say that despite being fit enough, the body doesn't know what to do with all the oxygen and hence exercise is more difficult? What does the second part mean, practically?
