Fig. 2From: The effect of thermal insulation pads on heat flux, physical effort and perceived exertion during endurance exercise in cool environmentsLower body clothing surface temperature (TLB) as measured after warm-up (t0) and after 45 min (t3) of running while subjects were wearing the thermally insulating (PINSUL) and non-insulating (PCOOL) pants in studies A (a) and B (b). Significantly lower TLB were found for PINSUL (p < 0.05) in study A and B indicating a lower heat flux with PINSUL compared to PCOOL. A significant effect of time (p < 0.05) was found in study B. Note: Asterisk indicates significant differences (p < 0.05) between PINSUL and PCOOLBack to article page
