a
range shows duration for shortened protocol-full protocol
b
duration in a steady-state of energy expenditure
c
sample size reduced due to shortened protocol (n=16)
d
walking/running activities took place on an indoor track with a pacer
e
sample size reduced due to inability to maintain a steady state of energy expenditure for ≥ one minute (n=13)
