Effect of KE and/or bicarbonate supplementation on plasma electrolytes. Data are presented as mean ± SD and represent plasma calcium (Ca2+) (A), sodium (Na+) (B), chloride (Cl−) (C), and potassium (K+) (D) concentration. In a randomized crossover design, participants (n = 9) received control (, CON), KE (, KE), bicarbonate (, BIC), or KE and bicarbonate (, KE + BIC) before and during exercise (gray zone). #P < 0.05 effect of BIC (BIC and KE + BIC vs CON and KE). IMT180′, 3 h submaximal intermittent cycling; TT, 15-min time trial; sprint, ~1-min all-out exercise bout at 175% LT.
