The Reliability And Validity Of Thermal Sensation Scales During Exercise In A Hot Environment.

Overview

Ratings of Perceived Exertion have been examined thoroughly in hot and cold environmental conditions. However, thermal sensation lacks extended evaluation.

Overview

Ratings of Perceived Exertion have been examined thoroughly in hot and cold environmental conditions. However, thermal sensation lacks extended evaluation. The purpose of this study was to determine the reliability and validity of the OMNI Temperature Sensation Scale (OTSS) compared to the Rohles Thermal Scale (RTS) during bouts of physical activity in a hot environment. Perceptual and physiological responses during prolonged bouts of exercise were examined in college aged men (N = 12) performing continuous exercise on a treadmill at 50% of each participants VO2max. Participants performed a preliminary trial to determine 50% VO2max workload, then participated in four exercise trials in a hot and humid environment of 35°C and a relative humidity of 45--55%. Data included thermal sensation scores from the OTTS and the Rohles Thermal Scale (RTS), core temperature values, and heart rate values. Pearson r correlations determined there was a positive linear relationship between the OTSS and the RTS. The findings from this study were statistically significant establishing the validity (r = .77; p < .0001) (CI = .71 to .84) and reliability (r = .81; p < .0001) (CI = .75 to .87) of the OTSS. However, the correlations that were established were expected due to the constrained variance of the scales. It was determined that the OTSS should not be used as a predictor of core temperature and heart rate and should only be used for general purposes due to the constrained variance. Key Words. Ratings of perceived exertion, thermal sensation, heat, humidity, core temperature, heart rate.
