Effects of SBE supplementation on serum levels of lactate after the 10-min swim.
| Groups | Vehicle | Isocaloric | SBE-1X | SBE-2X | SBE-5X | |
|---|---|---|---|---|---|---|
| Time Point | Lactate (mmol/L) | |||||
| Before swimming (A) | 3.34 ± 0.38 a | 3.32 ± 0.32 a | 3.25 ± 0.37 a | 3.45 ± 0.29 a | 3.33 ± 0.36 a | |
| After swimming (B) | 7.65 ± 0.57 c | 7.26 ± 0.50 c | 6.18 ± 0.71 b | 6.00 ± 0.72 ab | 5.54 ± 0.74 a | |
| After a 20 min resting (C) | 6.39 ± 0.47 c | 6.09 ± 0.54 c | 4.92 ± 0.52 b | 4.76 ± 0.42 b | 4.27 ± 0.52 a | |
| Rates of lactate production and clearance | ||||||
| Production rate = B/A | 2.30 ± 0.10 e | 2.19 ± 0.09 d | 1.90 ± 0.06 c | 1.74 ± 0.08 b | 1.66 ± 0.06 a | |
| Clearance rate = (B − C)/B | 0.16 ± 0.01 a | 0.16 ± 0.03 a | 0.20 ± 0.04 b | 0.21 ± 0.03 b | 0.23 ± 0.04 b | |
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, e) differ significantly between groups, p < 0.05.
