TABLE 2.
Effect of KE and/or bicarbonate supplementation on RPE and heart rate.
| CON | KE | BIC | KE + BIC | |
|---|---|---|---|---|
| RPE (6–20) | ||||
| WU | 10.8 ± 1.0 | 11.0 ± 1.0 | 10.3 ± 1.0 | 10.8 ± 1.3 |
| TT30′ | 18.1 ± 0.8 | 17.4 ± 1.6 | 17.3 ± 0.9 | 17.4 ± 1.2 |
| SPRINT | 18.8 ± 1.1 | 18.4 ± 1.1* | 19.0 ± 0.6 | 18.4 ± 1.2* |
| HR, bpm | ||||
| TT30′ | 167 ± 14 | 168 ± 11 | 168 ± 14 | 168 ± 13 |
| SPRINT | 177 ± 14 | 176 ± 12 | 178 ± 13 | 179 ± 11 |
Values are mean ± SD for RPE at the end of WU, TT30′, and SPRINT. HR is represented as mean ± SD for average HR during TT30′ and peak HR during SPRINT. In a crossover design, subjects (n = 12) received control (CON), ketone (KE), bicarbonate (BIC) or ketone and bicarbonate (KE + BIC) before and during exercise.
*P = 0.07 for effect of KE (KE and KE + BIC vs CON and BIC).
