only examined AP sway, the predicted CoP errors apply to ML sway as well. This is because the CoP (and CoB) calculated in the AP direction are only a result of vertical force, the torque applied at the foot, and horizontal frictional forces; thus, no amount of ML motion can change the CoP (or CoB

higher output values. Hofman et al 46 reported peak power of 18 and 24 W·kg −1 for female and male world-class speed skaters, when performed from a standstill start in a seated position. A limitation associated with the Wingate test is that the load (frictional resistance) is predetermined and

-emitting diodes during each trial. Recording time was 3 s and the recording frequency was 300 Hz. Using medical tape, a small piece of felt was secured to the tip of the participant’s index finger to reduce the friction between the finger and Plexiglas®. Muscle activity was recorded using a CED 1902 dual system

), which consisted of slalom sprinting with 100° COD set at 5-minute intervals. The maximum external load was set to 20% of BM, independent of equipment used, based on previous weighted vest 11 and sled 9 recommendations, as horizontal load was prescribed using the 1080 Sprint ™ . An estimated friction

In brief, the pedaling device was a direct drive apparatus constructed of nonmetallic materials that provided a light frictional workload.

Methodology 700-m On-Snow Trial Prior to the trials, the skiers performed a warm-up consisting of 20 minutes of low-intensity skiing, including 3 short periods (20–30 s) with increasing speed. Before the start of every trial, a test of glide friction was performed. 13

overcame the weight and friction force. The roller device had a seat and a footrest, as in a standard K1 boat. The feet were fixed according to the individual anthropometric characteristics with a knee angle of 120° to 130°. The shaft was fixed to the rails with a 50-cm-long rope. The left stroke was
