|Abstract: ||Introduction High-intensity intermittent exercise training
(HIT) may favourably alter body composition despite low
training volumes and predicted energy expenditure (EE).
Purpose To characterise the acute impact of two common
HIT protocols on EE and post-exercise oxygen consumption
(11 h EPOC).
Methods Oxygen consumption (l min−1), respiratory
exchange ratio (RER) and EE were measured in nine
healthy, lean males over 12 h under three conditions: control
(CON), HIT1 (10 × 1 min high-intensity cycling bouts
followed by 1 min rest) and HIT2 (10 × 4 min high-intensity
cycling bouts followed by 2 min rest).
Results Total exercise period EE during HIT1
(1,151 ± 205 kJ) (mean ± SD) was significantly lower than
HIT2 (2,788 ± 322 kJ; p < 0.001). EE within the 60 min
after exercise was significantly albeit marginally higher
after HIT1 (388 ± 44 kJ; p = 0.02) and HIT2 (389 ± 39 kJ;
p = 0.01) compared with CON (329 ± 39 kJ), with no
difference between exercise conditions (p = 0.778).
RER during this period was significantly lower in
HIT1 (0.78 ± 0.06; p = 0.011) and HIT2 (0.76 ± 0.04;
p = 0.004) compared with CON (0.87 ± 0.06). During the
‘slow phase’ of EPOC (1.25–9.75 h), there were no significant
differences in EE (p = 0.07) or RER (p = 0.173)
