Cyclist Endofibrosis (Exercise-Induced Arterial Endofibrosis) Treated by Drug-Coated Balloon Angioplasty

Exercise-induced arterial endofibrosis is an uncommon entity that is most frequently identified in high-performance athletes, especially cyclists. We present this disease in a male professional cyclist of 22 years of age. The course of his condition, clinical manifestations, modalities of investigation, and a nonprecedent treatment plan are demonstrated.

Heart Rate Responses and Exercise Intensity During A Prolonged 4-Hour Individual Cycling Race among Japanese Recreational Cyclists

Heart rate (HR) during different endurance cycling races and events are investigated for professional cyclist, however, enduro races to compete for total laps and distance covered within a fixed time using a circuit course has not yet been investigated. This study examined the heart rate (HR) and exercise intensity during an enduro cycling race. Ten male Japanese amateur cyclists performed cycling individually for at least 2 consecutive hours. HR was measured using an HR monitor during the race, and we estimated the energy expenditure (EE) during the race using the HR–VO2 relationship in advance. Exercise intensities were defined as percentages of HRmax based on ACSM exercise guideline as follows: moderate intensity, 64–76% HRmax; vigorous intensity, 77–95% HRmax. The HR during the race was 158.9 ± 10.6 bpm (86.4 ± 2.2% HRmax), and exercise intensity is categorized as vigorous intensity. The EE during the race using HR–VO2 relationship were 12.9 ± 1.2 kcal/kg/hr, which would require a large energy expenditure (EE) during the race. However, energy cost was 0.36 ± 0.04 kcal/kg/km regardless of total distance. The findings indicate that enduro cycling racing is categorized as vigorous intensity (>77% HRmax) for healthy male recreational cyclists though, cycling is an efficient form of transportation.

Comparison of anthropometric characteristics between world tour and professional continental cyclists

This study analyzed the physical characteristics of the World Tour (WT) and Professional Continental (PC) cyclists during the 2018 racing season. Seven hundred sixty-three professional riders (27.9 +4.2 years, 1.81 +0.06 m, 68.6 +6.33 kg) were compared for physical characteristics (i.e. age, height, and body mass). All riders were classified within specialties based upon UCI points ((grand champion (GC), sprinter (S), time trialists (TT), one-day racer (OD)) earned during the previous season. As expected there were differences between the rider’s specialty as well as the different elite divisions of riders. Further results showed that there was no difference in Body Mass Index (BMI; kg.m2) in all riders, however, TT riders in the WT had a significant difference in body surface area (BSA) and frontal area (FA) when compared to the TT riders in the PC division. In conclusion, the present study identified specific physical characteristic differences between the different types of professional cyclist levels of riders (WT vs. PC) and within their specialty.
