displacement of the BOS relative to the COM. Previous studies have reported that overground slip training induced by a vinyl floor and a low-friction movable platform can significantly reduce the rate of falls within the first several trials through immediate (ie, <5 min) improvements in COM state stability

safety harness connected to an automatic emergency brake. The rolling friction coefficient ( μ  = 0.021) of the roller skis (Swenor, Sarpsborg, Norway) was tested before, during, and after the experiments 21 and was unchanged during the study. Work rate was calculated as the sum of power against gravity

Importantly, the development of PUs can drastically impact an individual’s overall well-being and quality

classification could further be divided into fall and nonfall outcomes, and the no-LOB could also be further divided into walkover and skate over outcomes.

(radius: 35 cm). As seen through Figure  1 , the device was laid on a dual force platform (PF02, Equi+, Aix-les-Bains, France). The seesaw movements, positioned side-by-side to favor pitching body motions, were assumed to have no friction with the force platform. Figure 1 —Photograph showing the

improved performance during test 2 is affected by physiological priming or mainly explained by the learning effect of competing in the same track. Finally, we cannot fully exclude that the better performance during test 2 was due to better race conditions as we did not test the snow friction. However, the

research team warmed-up the KICKR by riding for 10 minutes at 100 W and then performed the “spindown” through the TrainerRoad software, which is a zero-offset calibration of the strain gauges based on bearing and belt friction. The zero offset procedure of the SRM was performed according to the

the turn, the dancer must exert a torque on the floor resulting in the production of a turning motion. The speed of the turn, which depends on the amount of friction with the ground, is also an important characteristic of the constraints on the movement and is controlled through the vertical impulse
