FIG. 2.

Blood lactate (BL) and total protein of whole saliva (TPWS) concentrations evaluated before exercise (R), at exhaustion (E) and 5 and 15 minutes after exercise (R5 and R15, respectively).

BL results of elderly elite athletes (a) and physically active elderly men (b), and TPWS results of elderly elite athletes (c) and physically active elderly men (d). One-way analysis of variance (ANOVA) with repeated measures, followed by the Tukey test for multiple comparisons, was used to compare the time points R0, E, R5 and R15. Results expressed as mean ± SEM. *There is a statistically significant change (p < 0.05).
