Additionally, the observed
changes in HR (rest vs. post 6MWT) in the current study were
modest. This may indicate that the 6MWT used in the current
study may not have been challenging enough to evaluate
exercise capacity. Furthermore, the smaller differences in BMI
between the 2 groups may not be detected by a submaximal
test such as the 6MWT.
Also, though BMI is regarded as one
of the most common indicators of OW and obesity, it is not
without limitations and is not an accurate measure of total
body fat mass
