The use of RPE has been validated in the sport of rowing during short intervals at different intensities; however, no research is known to have examined this phenomenon during long-duration rowing, nor investigated the impact of temperature on it within the sport. Previous research has shown that cardiovascular drift follows a pattern that is different in rowing than in running or cycling, which may have an impact on RPE, especially in different temperatures. PURPOSE: The current research aims to determine if there is a difference in RPE when rowing at the ACSM recommended temperature range (68°-72°) and in a slightly colder environment over time. METHODS: Two groups of 10 collegiate rowers, from a midwestern university, performed a 60’ minute submaximal exercise bout on a Concept2 rowing machine and were randomized to different ambient temperature settings (67° and 61°). Submaximal target speed was determined from a previous maximal exertion session. Each participant’s RPE was recorded at3 minutes intervals using the Borg’s Scale. The initial analysis determined if peak RPE differed between groups and was followed with a one-factor, two-level, repeated-measures ANOVA to determine if RPE differed between groups over time. RESULTS: Participants in the colder setting reported higher peak RPE (M = 5.4, SD= 1.65) versus participants in the warmer temperature (M=3.7, SD = .823) (t = -2.92, df = 18, p = .009). There was also a statistically significant difference in RPE through the interaction of time and temperature (F= 5.014, df = 1, 18, p = .012) meaning that as time progressed, participants in the colder group found it increasingly harder to maintain their submaximal target speed than the other group. CONCLUSION: Previous research has shown that exercising in lower temperatures reduces RPE in repetitive motion sports such as running and cycling; however, the current analysis does not uphold this trend in rowing. Our findings show that rowing on an ergometer in a colder setting maybe more psychologically pressing than in a warmer environment
