Subsarcolemmal lipid droplet responses to a combined endurance and strength exercise intervention.

Bottom Line: Lipid droplet volume in the subsarcolemmal LD population was reduced by ~80%, in both groups, while IMF LD volume was unchanged.Our results show that the SS LD lipid store was sensitive to training, whereas the dominant IMF LD lipid store was not.Thus, net muscle lipid stores can be an insufficient measure for the effects of training.

fig02: Lipid droplet (LD) diameters in the SS and IMF regions before and the 12‐week training intervention. (A) Dysglycemic group subjects. (B) Control group subjects.

Mentions: The size of LDs in the two regions responded differently to the training intervention (Fig. 2). The average, corrected diameter of the SS region was 933 nm (±162 SD) and 907 nm (±159 SD) for the dysglycemic group and the control group, respectively. Both groups responded to the training intervention by 28 and 26% reduction in LD diameter (P = 0.005 and P = 0.001), to 669 nm (±125 SD) and 659 nm (±106 SD), for the dysglycemic and control group, respectively.
