2.4.1. Exercise session
During the resistance-based session, which started at 0945, partici-
pants were asked to perform resistance training (Appendix 1) at 70%
of their 1RM, based on the intensity of the exercises determined by
the 12 RM test completed in the preliminary session. The net ExEE of
the exercise sessions was clamped at 4 kcal/kg. Exercises were grouped
in pairs in order to increase EE per amount of time [34]. The order in
which the pairs were performed is presented in Appendix 1. Each pair
was performed four times with 10 repetitions for each exercise, and
2 min of rest was given between supersets. This protocol was repeated
until target ExEE was reached. Extra series (e.g. leg press and leg curl exercises)
were added if the targeted ExEE was not reached at the end of
the protocol. Two water breaks of 5 min each (after the 8th and 16th
pairs) were added to the protocol because the length of this exercise
session was much longer than the aerobic exercise session. The participants
were also able to remove the facemask used to measure ExEE during
these water breaks. Five male participants were not able to complete
the resistance session on their first try due to high exertion and dizziness.
However, these five participants were able to complete this session
at a later date. The aerobic-based exercise session started at 1020
and consisted of running on a treadmill at an intensity of 70% of the participants
until the target ExEE was reached. Lastly, during the
control session, participants remained seated for the duration of the session
and were only allowed to do recreational reading.
