FIG. 4.

Analysis of Pearson’s correlation coefficient between blood lactate (BL) and total protein of whole saliva (TPWS), and BL anaerobic threshold (AT) and TPWS anaerobic threshold (PAT) of six elderly elite athletes during the incremental exercise test.

The blood lactate anaerobic threshold (AT) and the salivary total protein anaerobic threshold (PAT) were determined using the Dmax method during the incremental exercise test. AT and PAT are indicated by circles; distances related to TPWS are set on the right y-axis; distances related to BL are set on the left y-axis; time in minutes is set on the x-axis.
