Effect of intensity of resistance exercise on postprandial lipemia

Abstract

PURPOSE: To determine if moderate-intensity resistance exercise (MOD) lowers postprandial lipemia (PPL) as much as high-intensity resistance exercise (HI) of equal mechanical work. METHODS: Ten healthy men performed three trials, each conducted over 2 d. On day 1, they rested (CON), performed MOD, or performed HI. Three h after the trial, participants ate a low-carbohydrate meal (40% carbohydrate). On the morning of day 2, participants ate a high-fat meal (64% fat). Venous blood samples were collected in the fasted -1-1state and for 3 h postprandial. RESULTS: The total area under the TG curve (mmol·l·3h; mean ± SE) was lower after MOD (3.55 ± 0.73; p = 0.052; 26%) and HI (3.13 ± 0.42; p = 0.014; 35%) compared with CON (4.80 ± 0.89), but not different between MOD and HI. CONCLUSION: MOD and HI lower PPL to a similar extent.
