International Journal of Exercise Science 8(4): 331-340, 2015. This study examined practical pre- and mid practice cooling interventions on running performance, perceived exertion (RPE), and thermal sensation (TS) during soccer. During two formal pre-season practices female, NCAA Division II soccer players participated in three, 15 min scrimmage bouts followed by a 4th 10 min bout. Following the 1st, 2nd, and 3rd bouts, 8 field position players completed competitive sets of two, 30 yard sprints against other team members with time recorded between 5 and 30 yards. After the 4th bout, players completed an indoor shuttle running beep test (BT). In the treatment group (COOL) ice towels (IT) were applied to the head and neck regions and draped across both legs for 10 min following a standardized warm-up and for 10 min during a 15 min break between the 2nd and 3rd scrimmage sessions. Sport beverage slurries (350 mL; -0.3 °C, ~6% carbohydrate) were also served during IT cooling for COOL; while the control (CON) received no IT and drank the same ,uncooled sport beverage. No main effect was found for sprint performance (COOL = 3.55 ± 0.16 s; CON = 3.51 ± 0.07 s; P = 0.51) or numbers of reps completed in the BT (COOL = 17.6 ± 5.6; CON = 17.3 ± 6.0; P = 0.88). RPE did not differ following any performance test, but TS was lower following the 3rd sprint bout (P = 0.04) and the BT (P = 0.005) for COOL. COOL promoted lower TS, but had no effect on performance.
