The comparative effects of aerobic and resistance exercise on triglyceride-rich lipoproteins including remnant lipoproteins are controversial. This study examined exercise effect on remnant-like lipoprotein particle cholesterol (RLP-C) in type 2 diabetes. Participants were randomized to control (Control), aerobic (Aerobic), resistance (Resistance), or both (Combined) exercise groups. Baseline and 6-month fasting RLP-C and apolipoprotein B48 concentrations were measured. Data analysis was on an intention-to-treat basis. At 6 months, RLP-C was lower in all groups; ΔRLP-C mg/dl, (95% confidence interval), Control -3.91, (-6.21 to -1.6), p=0.001; Aerobic -3.89, (-6.41 to -1.36), p=0.003, Resistance -7.52, (-9.89 to -5.15), p=0.0001, Combined -7.50, (-9.87 to -5.13), p=0.0001. Total triglycerides were significantly lower in Resistance and Combined groups only; -17.7mg/dl (-32.8 to -2.7), p=0.02 and -27.5 (-42.5 to -11.5), p=0.001, respectively. Inter-group comparisons showed no difference in RLP-C change between Aerobic and Control and a significant difference in RLP-C change only where groups incorporating resistance exercise were compared with those without. There was no significant difference in RLP-C change between Resistance and Combined. Inter-group comparisons of total triglycerides change were significant only between Combined and Control. Changes in apolipoprotein B48 were not significant in inter-group comparisons. In conclusion, our data indicate that resistance exercise training, not aerobic, lowers RLP-C in type 2 diabetes. This effect was not revealed by changes in total triglycerides and apolipoprotein B48. The discordance between changes in RLP-C and apolipoprotein B48 in response to resistance exercise may indicate (a) a decrease in VLDL remnant and not chylomicron remnant particle number and/or (b) a depletion of cholesterol in chylomicron and/or VLDL remnants.
