Changes in body composition and psychological profile when overcoming four Everesting bike challenges

Problem Statement: During ultra-endurance races, given the long duration of the competitions, athletes can experience variations in body composition and moods. These elements can greatly affect the athlete's performance. Purpose: To evaluate the effects of an ultra-endurance race (4 consecutive Everesting Bike Challenges) on the body composition and moods of an adult athlete. Material and Methods: A well-trained amateur cyclist (male; 46 years; 64 kg; 1.69 cm; BMI 22.4 kg/m2) was monitored during the 4 Everesting Bike Challenges. This test is an ultra-endurance challenge that involves overcoming 8848 meters by climbing a single peak several times. The changes in body composition and hydration, calculated by bio-impedentiometry, and the changes in moods, obtained by administering the Profile of Mood States (POMS), in addition to Rating of Perceived Exertion (RPE) and Visual Analogic Scale, were measured at the beginning, during or at the end of each Everesting passed. Results: The resting heart rate was 42 beats per minute. The estimated theoretical maximal heart rate was 174 bpm. The monitored athlete overcame the 4 Everesting Bike Challenges covering a total of 904.79 km. The time taken to complete the race was 113 hours and 18 minutes. The total height difference exceeded was 35395 m. During the race the athlete pedaled with an average heart rate of 97 bpm. Body mass dropped from 64.0 to 63.1 kg between the start and end of the test. Wide variations in the athlete's Vigor (T0=16:T5=6), fatigue (T0=0:T5=6) and Sleep quality (T0=100:T5= ≈0) were found during the competition. Regarding the Rating of Perceived Exertion scale, the results obtained indicate a medium-low value (RP=3). Conclusion: The results of this study showed negligible reduction in body mass in the athlete who performed an ultra-endurance challenge. During and at the end of the climbing challenge, a significant reduction in Vigor and an important increase in Fatigue levels was highlighted, as well as a very evident reduction in Sleep quality. From the analysis of the RPE scale, medium-low values emerge at the end of each EBC
