Comparison of penile blood flow changes in performance road cyclists obtained during a ride on a customized 3D printed and conventional saddle Author: Bc. Václav Šňupárek Supervisor: PhDr. Helena Vomáčková, Ph.D. Aim: To update findings on penile blood flow in performance cyclists by measuring transcutaneous partial pressure of O2 (tcpO2) and CO2 (tcpCO2) on current style of racing bicycle saddles Subjects and methods: tcpO2 and tcpCO2 were measured non-invasively on the glans penis in healthy highly trained male cyclists (�ළ = 30) with an average annual mileage of 14240 km on three different road cycling saddles - Posedla Joyseat, Specialized Power and Fizik Tundra M5. It has previously been shown that tcpO2 is highly correlated with arterial pO2. TcpO2 and tcpCO2 were measured continuously in each participant for ten minutes on each saddle with a random order of saddles while riding stationary bike trainer in a race fit position. Simultaneously, various data like saddle surface pressure via Velometrik Smart Cover BT, rider position via Retül Fit, power output, heart rate and cadence via Wahoo KICKR Bike were recorded, and glans penis biothesiometry data were collected with Bio Medical Instruments. Data analysis was done on statistical level of significance �ළ < 0,05. Statistical methods used to...
