The aim of the study was to describe the distribution of training loads (TL) by the method of Subjective Rating of Perceived Exertion (RPE) sessions and verify your association with the changes of salivary markers (SM) in track and field athletes during a training. Participated in the study 44 athletes (17.5 ± 2.7 years; 175.1 ± 9.0 cm-1; 63.9 ± 10.7 Kg-1) being 11 sprinters, 11 jumpers, 11 runners and 11 athletes shot puts, evaluated for eight training sessions (duration between 120-150 min-1). Saliva samples were collected before and after the camping to evaluate cortisol levels, osmolality and total protein. The RPE was obtained thirty minutes after each session using the CR10 scale. The data normality was verified by the Shapiro-Wilk test. The comparison between groups was performed by ANOVA one-way and correlation between RPE and SM were obtained by Pearson correlation, considering p < 0.05. The distribution of TL they presented characteristic undulated and variability high. There was an increase in salivary osmolality in sprinters (55.0 ± 14.0 vs. 68.7 ± 22.6 mOsm.L-1; p=0.003) and jumpers (60.9 ± 17.9 vs. 77.8 ± 18.7 mOsm.L-1; p=0.001). The runners presented higher cortisol levels (p=0.007) compared to other groups. There were no correlations between sessions RPE and SM. Thus, the combination of perceptual and physiological assessments should be prioritized for better control and monitoring in athletes athletic.
