• Regular endurance exercise is an effective strategy for healthy weight maintenance, mediated via increased total daily energy expenditure (TDEE), and possibly an increase in resting metabolic rate (RMR: the single largest component of TDEE). Sprint interval training (SIT) is a low‐volume alternative to endurance exercise; however, the utility of SIT for healthy weight maintenance is less clear. In this regard, it is feasible that SIT may evoke a thermogenic response above and beyond the estimates required for prevention of weight gain (i.e., >200–600 kJ). The purpose of these studies was to investigate the hypotheses that a single bout of SIT would increase RMR and/or TDEE. Study 1: RMR (ventilated hood) was determined on four separate occasions in 15 healthy men. Measurements were performed over two pairs of consecutive mornings; each pair was separated by 7 days. Immediately following either the first or third RMR measurement (randomly assigned) subjects completed a single bout of SIT (cycle ergometer exercise). RMR was unaffected by a single bout of SIT (7195 ± 285 kJ/day vs. 7147 ± 222, 7149 ± 246 and 6987 ± 245 kJ/day (mean ± SE); P = 0.12). Study 2: TDEE (whole‐room calorimeter) was measured in 12 healthy men, on two consecutive days, one of which began with a single bout of SIT (random order). Sprint exercise increased TDEE in every research participant (9169 ± 243 vs. 10,111 ± 260 kJ/day; P < 0.0001); the magnitude of increase was 946 ± 62 kJ/day (~10%). These data provide support for SIT as a strategy for increasing TDEE, and may have implications for healthy body weight maintenance. e00131 A single bout of sprint interval training increases total daily energy expenditure by ~950 kJ. This observation provides support for the possible utility of regularly performed sprint interval training as a method of weight maintenance.
