This study investigated the effect of a single session of resistance exercise on postprandial lipaemia. Eleven healthy, normolipidaemic men aged 23 (SE 1.4) years performed two trials at least one-week apart in a counterbalanced randomized design. In each trial participants consumed a test meal (1.2g fat, 1.1g carbohydrate, 0.2 g protein and 68 kJ per kg body mass) between 08.00 and 09.00 following a 12 hour fast. The afternoon before one trial participants performed an 88 minute bout of resistance exercise. Prior to the other trial participants were inactive (control trial). Resistance exercise was performed using free weights and included 4 sets of 10-repetitions of each of 11 exercises. Sets were performed at 80% of 10 repetition maximum with a 2 minute work and rest interval. Venous blood samples were obtained in the fasted state and at intervals for 6 h postprandially. Fasting plasma triacylglycerol (TAG) concentration did not differ significantly between control and exercise trials (mean SE: 1.03 0.13 mmol•L-1 versus 0.94 0.09 mmol•L-1; respectively). Similarly the 6 h total area under the plasma TAG concentration versus time curve did not differ significantly between control and exercise trials (9.84 1.40 mmol•L-1•6 h versus 9.38 1.12 mmol•L-1•6 h; respectively). These findings suggest that a single session of resistance exercise does not reduce postprandial lipaemia.
