This study is for gaining an insight on how the environmental conditions influence the sliding speed of a skeleton. Unlike in other sliding sports, the runner’s stiffness can be adjusted on the skeleton for a specific track and environmental conditions. This decision is made intuitively. To help athletes, experiments are conducted at a bobsled push-start facility in Sigulda, Latvia. A portable 3-axis accelerometer will be used and vibrations during sliding will be measured at various environmental conditions. The conditions for performing the experiment are limited due to the length of the track which is 24m. In a previous study [1], a 2D mathematical model was developed to analyse the impact of the runner stiffness. This produced a good correlation with the results of the experiment and analysing the movement beyond the 24m limit was possible, and it was concluded that when increasing the runner’s stiffness, the sliding ability at higher speeds improves. Further experiments are carried out to monitor how skeleton’s sliding ability is affected by the temperature of ice and air and air humidity. Sliding velocity was mostly influenced by a change in temperature [2, 3]. The ice friction depends on sliding velocities [4], but the effects of air humidity more investigating are needed.
