Acute and residual effects of aerobic exercise on fructose-induced postprandial lipemia on lean male subjects

Abstract

Fructose consumption (0.5 g/kg) severely increased postprandial TG on day 1, but not on day 2. Previous exercise performance could lead to ~ 30% reduction on the AUC of postprandial TG in 13 h, but not after 37 h followed by fructose consumption. The regularity of physical exercise practice seems to be essential to promote a constant hypolipemic effect.

Exercise to Lower Postprandial Lipemia: Why, When, What and How

“…Since 2014, 36 studies have confirmed that exercise performed on the evening prior to a morning high-fat meal (that is, a meal containing above 0.7 g of fat per kg body mass) lowers PPL, compared to no exercise. This has been shown in young, middle-aged and/or older men [14,21,[33][34][35][36][37][38][39][40][41][42]22,43,76,77,23,[27][28][29][30][31][32], young men and women [44], young or middle-aged women [45,67], normal and overweight individuals [68], overweight and obese individuals [24,46,47] and adolescent boys and girls [48][49][50][51][52][53].…”

“…TAG reduction of 22% (range 4 to 35%) [14,28,[37][38][39][40][41][42][43][44][45][46]29,[47][48][49][50][51][52][53][54][55][56]30,[57][58][59][60][61][62][63][64][65][66]31,67,68,[32][33][34][35][36]. iv.…”

“…Most individuals are in a postprandial state during the largest part of the time they are awake, as they usually consume two to three main meals and intermediate snacks during the day. Additionally, dietary patterns characterized by high consumption of fat and carbohydrate, which prevail in many modern societies, lead to high PPL [4,14]. ii.…”

“…Walking, running or cycling for 30 to 90 min at intensities ranging from 45 to 70 % of VO 2 peak reduced PPL when performed on i. the day before a high-fat meal [14,21,28,29,33,36,39,40,42,46,49,50,53,76,77], ii. the day before a moderate-fat meal [54,55,57,58] or iii.…”

“…To document this, we examined how many of the original studies that are included in the present review and showed a significant effect of exercise on PPL satisfied the criterion of lowering circulating TAG by at least 1 mmo/L, which is the minimal established clinically relevant effect 15 16 . On this basis, 7 studies demonstrated a clinically relevant effect, with an average TAG reduction of 38% (range 29 to 47%) 21 22 23 24 25 26 27 , whereas 42 studies did not find a clinically relevant effect, with an average TAG reduction of 22% (range 4 to 35%) 14 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 .…”
