Knee flexion (240°/s, Nm)	7.48±4.58	5.66±4.15	0.658	−7.30±3.09	0.76±3.54	0.057
Grip strength (kgf)^b	4.42±2.05	2.83±1.85	0.382	−1.13±1.21	1.07±1.38	0.178

Changes are adjusted for baseline strength, tester concordance, and for the changes in K/Cr and Na/Cr. There were up to six scattered missing values for individual tests in the control group and up to three in the bicarbonate group
