The VO2 change scores for 1hr, 2hrs, and hrs post ingestion were significantly greater with FAS (22.1%, 19.3%, 16.5%) compared with P (-2.6%, -1.7%, -2.0%), C (9.9%, 8.5%, 3.5%) and with AC (12.0%, 9.3%, 12.5%). The AC condition produced significantly greater VO2 compared with PL at all three time points with CAF displaying values greater than PL at 1hr and 2hrs post ingestion. No significant main or interaction effects were detected in values of RER. The FAS condition produced significantly greater elevations in VE compared with PL at all three time points. Both CAF and AC produced significantly greater VE change scores than PL, at 1hr post ingestion. Values of VO2/VE were significantly reduced from baseline at 1hr and 2hrs post with FAS and were significantly lower at 1hr post with CAF while AC produced elevations in VO2/VE of 5%, 4%, 7%. The changes in HR were significantly greater with FAS than PL at 2hrs and 3hrs post (9.4 and 11.1bpm) while AC resulted in 2.5 and 4.1 bpm greater HR at 1hr and 2hrs post which were significantly greater than P. FAS produced significantly greater blood pressure changes at all three time points compared with PL (SBP↑33%, 26%, 19%; DBP↑26%, 10%, 15%). Changes in DBP were significantly greater than PL with CAF at 1hr (9.4%) and 2hrs (7.1%). Blood pressures were not significantly affected by AC.
