Weight Loss, Rectal Temperature and Heart Rates Following the 1984 Boston Marathron

摘要

This report summarizes the physiological changes that occurred in runners following the 1984 Boston Marathon. The marathon took place under cool and rainy weather conditions (WBGT range 6.5-10.5). Subjects for this study consisted of 57 males and 10 females. Their average age was 40.5 years (range 22-61 years). Average marathon pace was 219.1 m/min (X time = 3 hrs 12 min 36 sec). During the race, these runners drank an average of 581 mls. of fluid. As a result of running a marathon, heart rate increased from 61.3 bts/min to 91.2 bts/minute; body weight decreased from 67.3 kg. to 65.7 kg., and rectal temperature (T sub Re)was not significantly changed. Post-heart rate and T sub Re were affected by how soon after finishing the race an individual was measured. Runners who reported to the post-test site soonest tended to be younger and faster than those reporting later. Age and average weekly mileage correlated significantly with mean marathon pace. Our results with heart rate and T sub Re provide medical personnel with some guidance on the effect of the marathon on these parameters in uninjured runners.
