Effects of moderate- and intermittent low-intensity exercise on postprandial lipemia.
UNLABELLED The elevation of postpr and ial  plasma triglycerides ( PPTG ) in the blood is an independent risk factor for atherosclerosis . Although acute exercise typically attenuates PPTG , the effect of exercise intensity on PPTG is less well established , particularly in well-controlled conditions for physical activities and diet . PURPOSE We sought to determine the efficacy of exercise at 65 % V˙O2max with an extended sitting time and isoenergetic intermittent walking exercise at a self-selected walking speed ( approximately 25 % V˙O2max ) on PPTG compared with that of a sitting control condition . In a r and omized crossover design , nine healthy young men completed three trials with a > 1-wk interval between trials . After 2 d of activity and diet normalization , participants performed prolonged sitting nonexercise control ( CON ) , prolonged sitting with subsequent 1-h running at 65 % V˙O2max ( MOD ) , or isoenergetic intermittent walking at approximately 25 % V˙O2max ( LOW ) on day 3 . This was followed on day 4 by a 6-h high-fat tolerance test . RESULTS MOD and LOW reduced incremental triglyceride ( TG ) area under the curve ( TG AUCI ) compared with that in CON by 33.6 % ( P < 0.005 ) and 19.8 % ( P < 0.05 ) , respectively . MOD also reduced TG AUCI compared with that in LOW by 17.2 % ( P < 0.03 ) . The reduced TG AUCI in MOD was accompanied by reduced plasma glucose response and enhanced fat oxidation compared with those in LOW and CON ( for all , P < 0.05 ) , respectively . CONCLUSIONS Both MOD and LOW were effective in reducing PPTG compared with CON . However , MOD was more effective in reducing PPTG compared with LOW
