“…14 In our CAT's studies, the effects of PC on skin temperature were temporary and lessened as exercise progressed. For example, Clarke et al 4 observed that skin temperatures following PC were comparable with control skin temperatures after just 10 min of exercise.…”

“…The 4 studies [2][3][4][5] in Table 1 were the best evidence and selected for inclusion in this Critically Appraised Topic (CAT). These studies were included because they were considered to be level-2 evidence or higher, had PEDro scores ≥ 5, and compared TS and perceived exertion during exercise in the heat with or without PC.…”

“…7 Based on our results (Table 2), there was no evidence to suggest that PC before exercise caused clinically meaningful differences in RPE during exercise compared with the control condition. This could be the result of our selected studies' [2][3][4][5][6] designs. All the studies in our CAT used crossover designs that would have minimized age and psyche as factors contributing to differences in RPE.…”

In four studies, RPE during exercise ranged from 12 ± 2 to 20 ± 3 with no clinically meaningful differences between PC and control trials. Thermal sensation scores ranged from 2 ± 1 to 8 ± 0.5 in control trials and from 2 ± 1 to 7.5 ± 0.5 during PC trials. Clinical Bottom Line: Precooling did not cause clinically-meaningful differences in RPE or TS during exercise. It is unlikely PC would predispose athletes to EHS by altering perceptions of exercise intensity or body core temperature. Strength of Recommendation: None of the reviewed studies (all level 2 studies with PEDro scores ≥5) suggest PC with CWI influences RPE or TS in exercising males.

“…Players must execute soccer-specific skills and make complex decisions throughout a match. Some indirect data have suggested that cooling may improve such actions, 35 but we did not measure this. Authors of a position statement 21 have suggested that soccer-match percooling might be a practical, effective way to maintain performance and minimize the health risks of competing in the heat.…”

Context Precooling and midevent cooling of the torso using cooling vests can improve exercise performance in the heat with or without physiological changes; however, the effects of such cooling during intermittent exercise in the heat are unknown. Objective To investigate the effects of torso cooling during intermittent exercise in the heat (35°C, 50% relative humdity) on sprint performance and the physiological and perceptual responses to the exercise. Design Crossover study. Setting Walk-in environmental chamber. Patients or Other Participants Ten non–heat-acclimated, male soccer players (age = 25 ± 2 years, height = 1.77 ± 0.06 m, mass = 72.9 ± 7.6 kg). Intervention(s) Two 90-minute bouts of soccer-specific intermittent running in the heat: 1 trial with a cooling vest worn during the exercise and 1 trial without a cooling vest. Each trial comprised two 45-minute periods separated by approximately 15 minutes of seated rest in cool conditions (approximately 23°C, 50% relative humdity). Main Outcome Measure(s) Peak sprint speed, rectal temperature (Tr), mean-weighted skin temperature (Tsk), heart rate (HR), rating of perceived exertion (RPE), and thermal sensation (TS) were measured every 5 minutes. Results Peak sprint performance was largely unaffected by the cooling vest. The Tr, Tsk, HR, RPE, and TS were unaffected in the cooling-vest trial during the first 45 minutes, but Tr rose at a slower rate in the cooling-vest trial (0.026°C.min–1 ± 0.008°C.min–1) than in the no-vest trial (0.032°C.min–1 ± 0.009°C.min–1). During the second 45-minute period, Tr, Tr rate of rise, Tsk, RPE, and TS were lower in the cooling-vest trial (Hedges g range, 0.55–0.84), but mean HR was unaffected. Conclusions Wearing a cooling vest during soccer-specific intermittent running in the heat reduced physiological and perceptual strain but did not increase peak sprint speed.
