Figure skaters have been pushing for updated equipment (especially boots, the part of the skate that encases the feet) for some time, as injuries over the past few decades have soared. In a Wall Street Journal article from 2006, orthopedist Leisure Yu noted that skate makers were still using designs from the 1800s. Unfortunately, it doesn't seem like much has changed, and there isn't a ton of data out there about figure skating injuries -- until now. In a new study in the journal Measurement Science and Technology, researchers describe a new way to measure the stresses of figure skating. They have figured out how to build an ice skating blade (pictured below) that directly measures the impact a skating routine can have on an athlete's body.
