Acute Effects of Shortly Pre- Versus Postprandial Aerobic Exercise on Postprandial Lipoprotein Metabolism in Healthy but Sedentary Young Women

The Ingestion of a Fructose-Containing Beverage Combined with Fat Cream Exacerbates Postprandial Lipidemia in Young Healthy Women

“…In each test trial, the subjects ingested one of four beverages containing fructose (F) and/or glucose (G) (total: 0.5 g/kg body weight) combined with oral fat tolerance test (OFTT) cream (Jomo, Takasaki, Japan; 1 g/kg, 0.35 g/kg as fat) in a randomized crossover design. The OFTT cream was used as previously described 8,[10][11][12][13] . The four beverages were prepared as follows: F100: 100% (w/w) fructose (Nisshin Seito, Tokyo, Japan), F90G10: 90% fructose 10% glucose (Fuso Pharmaceutical, Osaka, Japan), F55G45: 55% fructose 45% glucose and G100: 100% glucose.…”

Simultaneous Ingestion of Fructose and Fat Exacerbates Postprandial Exogenous Lipidemia in Young Healthy Japanese Women

“…The remnant lipoprotein cholesterol (RemL-C) level was measured using a homogenous assay (MetaboRead TM , Kyowa Medex). In our previous studies, the serum concentration of RLP-C was measured using the immunoaffinity separation method 16) ; however, the RLP-C concentration measured using this method is sometimes less than the lower limit of detection in young Japanese women 14) . In the present study, the serum concentration of RemL-C was therefore measured using a newly developed homogenous assay 16) , and no samples were found to contain a concentration below the detection limit.…”

“…Postprandial metabolism was quantified by calculating the incremental area under the curve (⊿AUC), which was defined as the difference between the area under the curve and the area below the baseline (0 hours) concentration from 0 to 6 hours, as previously described 14) . Postprandial changes in the concentrations of TG, RLP-TG, RemL-C, apoB and apoB48 were calculated as the difference from the baseline mean value (as 0 at 0 hours) and shown as ⊿TG, ⊿ RLP-TG, ⊿RemL-C, ⊿apoB and ⊿apoB48, respectively.…”

“…At each test trial, the subjects ingested one of four beverages containing either fructose or glucose (0.5 g/kg body weight each) with or without oral fat tolerance test (OFTT) cream (Jomo, Takasaki, Japan; 1 g/kg, 0.35 g/kg as fat) in a randomized crossover design. OFTT cream was used as previously described [12][13][14] . The four beverages were prepared as follows: Fru: 0.5 g/kg of fructose (Nisshin Seito, Tokyo, Japan) mixed with no-sugar soda (Suntory, Tokyo, Japan); Fat: 1 g/ kg of OFTT cream; Fru+Fat: fructose (0.5 g/kg) mixed with no-sugar soda supplemented with OFTT cream (1 g/kg); Glu: 0.5 g/kg of glucose (1.5 mL/kg of Trelan-G75 TM , 1 g/3 mL as glucose, Ajinomoto, Tokyo, Japan).…”

Dyslipidemia Induced by Stress

“…Although exercise cannot change total cholesterol and LDL-cholesterol unless dietary fat intake is reduced, this result may be dependent on the amount of energy expenditure during exercise (Durstine et al, 2002). Furthermore, depending on the time that the exercise is performed (before or after ingestion of fatty foods), its acute responses related to improvement in lipoprotein metabolism may be different (Hashimoto et al, 2011). In a review of several studies realized by Leon & Sanchez www.intechopen.com 2001, one of proposals evaluated was the effects of aerobic exercise training on blood lipids and the relationship between these effects and diet.…”
