“…This reduction in performance is due to the increase in the perception of effort and physiological stress in athletes [12,13]. High thermal stress situations can cause cognitive ability changes in players [14] and technical actions [15]. In the case of Brazilian players, thermal stress is especially worrying because most of the year, the regions have high temperatures [7].…”

In recent years, climate phenomena, such as global warming, have represented a risk to players. Thus, studies involving outdoor sports and high temperatures have been conducted to show the influence on athletes' performance. However, this information requires greater clarity in the scientific community. The purpose of this study was to investigate the effects of heat stress on running performance in matches played during a Brazilian championship. Thirty matches were analyzed from 20 professional soccer players who belonged to the team in the state of Rio de Janeiro during the Brazilian elite championship (2019). To quantify running performance during soccer matches, players used GPS device units. Temperatures were classified by the Cluster method into three groups: high (35.9–29.5 C), moderate (26.4–21 C) and low (20.0–14.1 C). The 1-minute peak of acceleration and deceleration was greater in high temperature situations (p = 0.02–0.03). In matches with low temperatures, accelerations, decelerations, high-intensity running, and sprinting were greater (p = 0.01–0.02). Significant correlations, negative and low, for sprinting (r = − 0.23; p = 0.01), acceleration (r= -0.29; p = 0.001) and deceleration (r= -0.24; r = 0.007). The temperature influenced the running performance of soccer players.
