Exercise performance is reduced in hot environments due to physiolog-ical responses caused by increased body temperature. A proper resi-dential environment is important for improving the performance and maintaining physical condition of soccer players in the summer. The purpose of this study was to determine the effect of indoor temperature of the resting space during the summer on the fitness and condition of soccer players. A total of 12 K-3 League semiprofessional players with-out serious injuries in the last 3 months voluntarily participated in the study. Participants performed speed (10 m, 20 m, and 30 m), soccer-spe-cific coordination skill (dribbling), agility, repeated sprints, Yo-Yo inter-mittent level 2, vertical jump, and questionnaire (fatigue, sleep quality, muscle soreness, stress, and mood) after staying indoor temperature at 20°C, 26°C, and 30°C for one night, respectively. There was no differ-ence among groups in physical fitness (speed, agility, jump, coordina-tion, Yo-Yo intermittent level 2, and repeated sprints). The differences in fatigue and sleep quality were not statistically significant among groups, but they tended to be different. Muscle soreness was similar among all groups. Significant differences were observed between the 20°C and 30°C groups in stress and mood levels. The present study con-cluded that, while the physical fitness did not differ among groups, the 30°C residential environment was shown to have a negative psycholog-ical effect. Considering that many diseases associated with hot weath-er occur in low residential temperatures, a room temperature of 26°C is recommended for elite soccer players in hot summer weather.
