Before main trials, participants visited the laboratory to undergo
preliminary assessments (questionnaires, anthropometry, exercise
testing) and to be familiarised with the laboratory environment
and study procedures. Specifically, participants completed questionnaires
assessing health status, food preferences, habitual physical
activity and psychological eating tendencies (Three-Factor Eating
Questionnaire (TFEQ)) . Participants
scoring 11 or more for any factor on the TFEQ were determined to
exhibit restrained or disinhibited eating tendencies, and consequently
excluded from taking part. Height was measured to the
nearest 0.1 cm using a stadiometer (Seca Ltd, Germany) and body
weight was measured to the nearest 0.01 kg using a balance beam
scale . Body mass index (BMI)
was subsequently calculated as weight (kg) divided by height (m2).
Waist circumference was determined as the narrowest part of the
torso between the xiphoid process and the iliac crest
To determine the treadmill speed required to elicit 70% of
maximum aerobic capacity during main trials, two preliminary
running tests were undertaken; 1) a progressive-submaximal test
to determine the relationship between treadmill speed and oxygen
consumption, 2) a peak oxygen uptake test. Both tests have been
described in-depth previously . During each test, oxygen consumption and carbon
dioxide production were determined from frequent expired air
samples collected into Douglas bags and analysed using a dry gas metre and paramagnetic oxygen/infra-red carbon
dioxide analyser
