We determined fitness using
a maximal treadmill exercise test and a modified Balke protocol32 as previously described.12, 13,33,34 Total test time correlates highly (r ≥ 0.92) with directly measured maximal oxygen uptake in men35 and women.36 Participants were encouraged not to hold onto the treadmill handrails.

High - intensity interval training is a process in which a person performs near
maximal exercise for a short period of time, and then performs two to four minutes of active recovery; for example, if someone is on a
treadmill they may go from running to walking.
VO2 max (also referred to as
maximal oxygen consumption, peak oxygen uptake) is the maximum rate of oxygen consumption as measured during incremental
exercise, usually on a
treadmill or cycle ergometer.
Beta - endorphin levels are high in pregnancy and increase throughout labor, (15) when levels of beta - endorphin and corticotrophin (another stress hormone) reach those found in male endurance athletes during
maximal exercise on a
treadmill.
All participants completed one endurance
exercise session at the start of the study which consisted of a 5 min warm - up (walking) followed by 30 minutes of
exercise on a
treadmill (0 % grade) at ~ 65 % of
maximal heart rate, which represents a moderate intensity and ended with a 5 min cool down.
