1. Error in Figure/Table

First, in the original publication [1], there was a mistake in Table 1 as published. The data in Table 1 were wrong and the group name was wrongly marked; SBE-5X should be changed to SBE-4X. The corrected

Table 1. Effects of SBE supplementation on serum levels of lactate after the 10 min swim test. The lactate production rate (B/A) was the value of the lactate level after exercise (B) divided by that before exercise (A). The clearance rate (B − C)/B was defined as the lactate level after swimming (B) minus that after 20 min of rest (C) divided by that after swimming (B). Data are expressed as mean ± SD (n = 10 mice per group). Values in the same row with different superscript letters (a, b, c, d) differ significantly between groups, p < 0.05.

Fourth, in the original publication, there was a mistake in Figure 4 as published. The group name was wrongly marked, SBE-5X should be changed to SBE-4X. The corrected Figure 4 appears below.

2. Text Correction

There was an error in the original publication. The group name was wrongly marked; SBE-5X should be changed to SBE-4X.

A correction has been made to Section 2; Results Section 2.3. Effect of SBE Supplementation on Fatigue-Related Biochemical Indicators after the 10-min Swim Test or a 90-min Swim Test and a 60-min Rest, Paragraphs 1 and 2:

We also evaluated the NH₃ and BUN concentration after the 10-min swim test. As shown in Figure 2A, the NH₃ levels in the vehicle, isocaloric, SBE-1X, SBE-2X, and SBE-4X groups were 167 ± 18, 144 ± 19, 145 ± 17, 133 ± 18, and 148 ± 17 (umol/L), respectively. The SBE-1X, SBE-2X, and SBE-4X groups were significantly lower than the vehicle group, i.e., by 13.11% (p = 0.0089), 20.42% (p = 0.0001), and 11.38% (p = 0.0221), respectively, but no dose-dependent trend was observed.

We measured the serum BUN level after the 90-min swim test followed by 60 min of rest. As shown in Figure 2B, the BUN levels in the SBE-1X, SBE-2X, and SBE-4X groups were 46.5 ± 1.8, 46.5 ± 2.0, 38.5 ± 2.2, 35.5 ± 2.2, and 34.8 ± 1.5 (mg/dL), respectively. Compared with the vehicle group, the SBE-1X, SBE-2X, and SBE-4X groups were significantly lower by 17.26% (p < 0.0001), 23.78% (p < 0.0001), and 25.22% (p < 0.0001), respectively. In addition, they were significantly lower than the isocaloric group by 17.27% (p < 0.0001), 23.79% (p < 0.0001), and 25.23% (p < 0.0001), respectively. For the trend analysis, serum BUN levels after the 90-min swim test followed by 60 min of rest had decreased dose-dependently with SBE supplementation (p < 0.0001).

In addition, a correction has been made to Section 2; Results Section, 2.4. Effect of SBE Supplementation on Liver and Muscle Glycogen Contents, Paragraphs 1 and 2:

The liver glycogen content in the vehicle, isocaloric, SBE-1X, SBE-2X, and SBE-4X groups were 15.87 ± 0.93, 15.69 ± 1.24, 20.76 ± 3.65, 23.24 ± 1.98, and 23.97 ± 0.51 (mg/g liver), respectively. The SBE-1X, SBE-2X, and SBE-4X groups were significantly greater than the vehicle group by 1.31-fold (p < 0.0001), 1.46-fold (p < 0.0001) and 1.51-fold (p < 0.0001), respectively, and also were significantly greater than the isocaloric group by 1.32-fold (p < 0.0001), 1.48-fold (p < 0.0001) and 1.53-fold (p < 0.0001), respectively (Figure 3A).

The muscle glycogen content in the vehicle, isocaloric, SBE-1X, SBE-2X, and SBE-4X groups were 1.35 ± 0.08, 1.36 ± 0.07, 1.57 ± 0.08, 1.67 ± 0.05, and 1.73 ± 0.06 (mg/g muscle), respectively. The SBE-1X, SBE-2X, and SBE-4X groups were significantly greater than the vehicle group by 1.16-fold (p < 0.0001), 1.24-fold (p < 0.0001) and 1.28-fold (p < 0.0001), respectively, and were also significantly greater than the isocaloric group by 1.15-fold (p < 0.0001), 1.22-fold (p < 0.0001) and 1.26-fold (p < 0.0001), respectively (Figure 3A).
