The main purpose of this study was to check any relationship between mood states heart rate, variability (HRV) and creatine kinase (CK) of Brazilian para-athletes. Were evaluated 12 athletes, members of the Brazilian Team of Para-Athletics. In order to evaluate the autonomic response the HRV of athletes was determined at rest, by collecting the R-R intervals within 10 min. It was also collected blood samples to analyze the total CK, and the Brums scale was applied to know the mood states of the athletes, being calculated the six mood states (tension, depression, anger, fatigue, confusion and vigor). Analysis of the data was performed by Spearman correlation. The main results indicated a relationship between the parasympathetic modulation and the Vigor of the athletes (r = 0.50 to 0.53; p<0.05). The CK was not related with any marker. In conclusion: There was a relationship between the parasympathetic modulation of HRV and the Vigor, which is good for the performance.
