Abstract

The purpose of this study is to investigate physiological responses during a traditional active warm-up and a passive warm-up consisting of wearing heated trousers during a submaximal endurance cycling workout. Participants included 10 cyclists/triathletes (3 females, 7 males; age: 48 ± 13 years old; mass: 157.9 ± 33.8 kg; height: 169.3 ± 8.65 cm; percent body fat: 25.3 ± 8.53 %) of at least 18 years of age who could continuously cycle for at least 120 minutes and had knowledge of their individual FTP. Experimental 1-day testing included a randomized crossover design where participants proceeded with two different protocols: an active warm-up cycling 15 minutes and a passive warm-up wearing heated trousers for 15 minutes. Following each protocol, participants were then asked to cycle at a submaximal level of 70% FTP. Dependent variables that were taken during submaximal exercise included core temperature, skin temperature, VO2, CO2, RER, heart rate, and cycling economy. Dependent paired t-tests were run on SPSS 28th edition (IBM SPSS Statistics Data Editor, SPSS Version 28.01.00) for data reduction and analysis with significance set at P ≤ 0.05. Data analysis revealed that there were no significant differences in core temperature (P > 0.05), skin temperature (P > 0.05), VO2 (P > 0.05), CO2 (P > 0.05), RER (P > 0.05), heart rate (P > 0.05) and cycling economy (P > 0.05). These findings suggest that utilizing heated trousers in place for an active warm-up could be considered as there were no significant advantages or disadvantages during submaximal cycling exercise.
