BODY TEMPERATURE LOWER WHEN EXERCISING ON BIKE IN HEAT

Abstract

When a person exercises in a hot environment a logical assumption is that the higher the environment temperature higher body temperature would rise given that intensity stayed the same. PURPOSE: The purpose of this study was to determine if body temperature during exercise on a bike in elevated temperature (28̊C) compared to exercising at normal room temperature (22̊ C). METHODS: Nine Subjects were tested in two different trials on the Bike Ergometer. The first trial consisted of cycling for 30 minutes at 85% of the maximal heart rate at room temperature. The second trial consisted of cycling for the same duration and intensity at an elevated room temperature of (29̊C). Subjects did a 5 minute warm up session to elevate their heart rate to 85% of their maximal heart rate prior to time starting. RESULTS: Results indicated that the cool environment led to a body temperature of 36.86°C ± 0.17, and the hot environment resulted in a body temperature of 37.06°C ± 0.14. A t-test was conducted indicating significant difference in the means (p<0.05). CONCLUSION: This study suggests that there is no difference in body temperature while exercising on a bike in elevated environmental temperatures compared to a more neutral temperature based on the data.
