Introduction: In the recovery period after exercise there is an increase in oxygen uptake termed excess post-exercise oxygen consumption
(EPOC). The magnitude of EPOC after aerobic exercise may depend on duration and intensity of exercise, on type of exercise (split
exercise or continuous sessions) and on training status and sex. It is not clear whether various modes of aerobic exercise affect EPOC
differently (Børsheim, 2003). Cycling exercise (CE) has been compared with treadmill and arm crank exercise separately but the impact of
cross-training exercise (CTE) on EPOC has not yet been examined. The aim of this study was to evaluate the acute effects of moderate
intensity CE and CTE on EPOC.
Methods: 6 young moderately active female (age, 24,2±0,8 yr; BMI, 21,5±2,4 kg/m2; RMR, 1288±78,2 kcal/day) participated in the study
over a 2-week period. In the first week subjects filled a Baecke questionnaire of habitual physical activity, undergone a resting metabolic
rate (RMR) measurement and 3 incremental tests to exhaustion (V’O2peak at treadmill, cycle ergometer and arm ergometer). In the
second week they completed two bouts of 30 min of exercise at 60% of V’O2peak separated by 48 hours of rest: a continuous CE and a
combining running, cycling and arm crank for 10 min each. Before (30 min pre) and after (2 hours post) each exercise bout a RMR measurement
was carried out in a sitting position (K4b2, Cosmed, Italy). A One-way Anova was used to analyse data and significance was
