|Abstract: ||PURPOSE: South Asians have a higher than average risk of coronary heart disease. The
reasons for this are unclear but physical inactivity and/or poor responsiveness to exercise may
play a role. This study compared the effect of prior exercise on postprandial triacylglycerol
(TAG), glucose, insulin, interleukin-6 (IL-6) and soluble intercellular adhesion molecule-1
(sICAM-1) concentrations in South Asian and European men.
METHODS: Ten healthy South Asian men (i.e. nine Indian men and one Pakistani man) and 10
healthy European men aged 20 to 28 years completed two, 2-day trials (exercise and control)
in a randomised-crossover design. On the afternoon of day 1 of the exercise trial, participants
ran on a treadmill for 60 minutes at approximately 70% of maximal oxygen uptake.
Participants rested on day 1 of the control trial. On day 2 of both trials participants rested and
consumed high fat (57% of energy content) test meals for breakfast (0 h) and lunch (4 h).
Fourteen venous blood samples were collected from a cannula between 0 h and 9 h for
RESULTS: Three-way ANOVA identified higher (P < 0.05) postprandial TAG and insulin
concentrations in South Asian versus European men. Exercise lowered postprandial TAG and
IL-6 and elevated sICAM-1 concentrations. An interaction effect indicated a greater decrease
(22 versus 10%) in TAG area under the concentration versus time curve after exercise in
South Asian than European men.
CONCLUSIONS: Postprandial TAG and insulin responses to high fat meals were elevated in
these South Asian men but acute exercise was equally if not more effective for reducing
postprandial lipemia in South Asian than in European men.|
