Muscle-specific glucose and free fatty acid uptake after sprint interval and moderate-intensity training in healthy middle-aged men. J Appl Physiol 118: 1172–1180, 2015. First published March 12, 2015; doi: https://doi.org/10.1152/japplphysiol.01122.2014.—There was a technical error in muscle glucose uptake calculation affecting the values so that all the published values were 1.44 times too high. This was because muscle glucose uptake should have been calculated by the formula: muscle glucose uptake = fractional tracer uptake rate × plasma glucose concentration/lumped constant value of 1.2 and instead of dividing by lumped constant of 1.2, values were multiplied with it, thereby causing 1.44 times too high values. Figures 2 and 3 have been corrected respectively. In addition, the authors have noted that the M-value results of one subject were missing from the analysis and that affected the respective results in the Table 1 accordingly. Table 1 has been corrected respectively.Corrected Figs. 2 and 3 and Table 1 are shown below.Fig. 2.Skeletal muscle glucose uptake (A and B) and free fatty acid (FFA) uptake (C and D) in lower- and upper-body muscles. A and C: results from SIT group. B and D: results from the MIT group. Open bars show before, and shaded bars show after the training intervention. QF, quadriceps femoris; HAM, hamstrings; DEL, deltoids, BIC, biceps brachii; TRI, triceps brachii. Values are model-based means (95% confidence interval). *P < 0.001 for the time effect (pre- vs. posttraining comparison).Download figureDownload PowerPointFig. 3.Skeletal muscle glucose uptake (A and B) and FFA uptake (C and D) in the four heads of the QF muscle. A and C: results from SIT group. B and D: results from the MIT group. Open bars show before, and shaded bars show after the training intervention. RF, rectus femoris; VL, vastus lateralis; VI, vastus intermedius; VM, vastus medialis. Values are model-based means (95% confidence interval). *P < 0.05 for the time effect (pre- vs. posttraining comparison). #P < 0.05 for the group × time interaction in RF compared with group × time interaction in the other three muscles.Download figureDownload PowerPointTable 1.
