A Comparison of Skating Economy On-Ice and On the Skating Treadmill

Canadian Journal of Applied Physiology, 2003
The purpose of this study was to compare skating economy and oxygen uptake (VO2) on-ice and on the skating treadmill (TM). Male varsity hockey players (n = 15, age = 21.0 yr) performed skating tests on a TM and on-ice. The subjects skated for 4 min at each of 3 submaximal velocities (18, 20, and 22 km • h−1), separated by 5 min of passive recovery.

Adaptation in Skate Photoreceptors [PDF]

The Journal of General Physiology, 1972
Receptor potentials were recorded extracellularly from the all-rod retina of the skate after the application of sodium aspartate. This agent suppresses the responses of proximal elements, but leaves relatively unaffected the electrical activity of the photoreceptors (a-wave) and pigment epithelium (c-wave).

Push-off mechanics in speed skating with conventional skates and klapskates [PDF]

Medicine & Science in Sports & Exercise, 2000
Personal and world records in speed skating improved tremendously after the introduction of the klapskate, which allows the foot to plantar flex at the end of the push-off while the full blade continues to glide on the ice. The purpose of this study was to gain insight into the differences in skating technique with conventional versus klapskates and to

Integrability and Chaos in Figure Skating [PDF]

Journal of Nonlinear Science, 2019
We derive and analyze a three dimensional model of a figure skater. We model the skater as a three-dimensional body moving in space subject to a non-holonomic constraint enforcing movement along the skate's direction and holonomic constraints of continuous contact with ice and pitch constancy of the skate. For a static (non-articulated) skater, we show

Endurance in Speed Skating

, 2001
We analyse the development of world records speed skating from 1893 to 2000 for both men and women. The historical data show that it is likely that the relation between skating speed and distance of the various events is non-linear and converges to a limit value.
