This research was conducted in the town of Redenção of Gurguéia in the southern region of the state of Piauí. The region has a semi-arid tropical climate type, which corresponds to the high temperatures and dry climate, in the period of summer rainy season dragging for fall, common to all regions of northeastern Brazil. 27 adult crossbred horses race quarter mile aged (5-16 years) were used, nine males with white fur, with nine -nine sorrel coat with red fur. Heart rate (HR) and respiratory rate (RR) were performed. Thermal environment in a black globe with the purpose of recording the internal temperature of the animal at the beginning and end of each time of sampling, to calculate the rate of global temperature and humidity (BGT) was installed. The variations between the characteristics measured were significantly different (P < 0.05) between the two rounds of collections that corresponds to the 1st morning shift (T1) and 2 afternoon shift (T2) for heart rate (HR), respiratory rate (RR) and the rate of global temperature and humidity (BGT). The respiratory rate (RR) was positively correlated with FC (0.65).
