I found the wild card result in the skate tests discussed in my last post shocking but not unexpected. I had known for decades that ski boots can dramatically impact user performance. But until the skate tests I had no way of confirming my subjective observations, which could be summarily dismissed as nothing more than my opinion. The results of the skate test provided convincing support for my long held assertion that testing the effect of ski boots on the user with a set of realistic performance metrics is absolutely essential.
In the graph below of Peak Force all 5 competitive skaters improved in the NS.
Skater number four went from the skater with lowest Peak Force to the skater with the highest Peak Force. But skater number one, who had the fourth highest Peak Force in their OS, hardly saw any improvement in the NS whereas skater number four realized over a 100% increase in Peak Force!But the real shocker was in Impulse Force. As expected, results varied. But the Impulse Force of skater number one actually decreased slightly in the NS!Without a standardized, validated test protocol there is no way of knowing how their ski boots affected the performance of the competitors in the Soelden GS or any race for that matter. Guessing should not be acceptable.
