Table 1 Changes in forehead temperature (Tface) with facial cooling (FC)

From: Intermittent face cooling reduces perceived exertion during exercise in a hot environment

Variables CONT FC4 FC2 FC2-20
Tface at BL, °C 35.9 ± 0.4 35.9 ± 0.5 36.1 ± 0.2 35.9 ± 0.2
Tface before FC, °C 36.8 ± 0.4 36.6 ± 0.4 36.2 ± 0.4# 36.3 ± 0.3
Tface after FC, °C 36.7 ± 0.4 34.2 ± 1.1# 33.9 ± 0.6# 35.0 ± 0.5#*
Tface decrease with FC, °C 0.0 ± 0.0 2.3 ± 1.0# 2.2 ± 0.5# 1.3 ± 0.4#*
  1. Values are means ± SD; Tface at BL, forehead temperature during base line; Tface before FC; average forehead temperature immediately before all facial cooling during each trial; Tface after FC, average forehead temperature 20 s after the beginning of facial cooling; Tface decrease with FC, difference between forehead temperature before and after facial cooling; CONT, control exercise trail; FC4, facial cooling with 0 °C packs at 4-min intervals; FC2, facial cooling with 0 °C packs at 2-min intervals; FC2-20, facial cooling with 20 °C packs at 2-min intervals. #P < 0.05, significant difference compared to the CONT trial. *P < 0.05, significant difference compared to the FC2 trial
