IS SKATING ON A TREADMILL THE SAME AS SKATING ON ICE?

There is definitely a “stigma” in the hockey world surrounding skating on treadmills as a development tool. A common paradigm is that by skating on a treadmill it will significantly alter a player’s stride or even increase their risk of sustaining an injury. Without a doubt the skating treadmill is something that can never replace skating on the ice and should be used in conjunction with on-ice training as a tool to help improve your skills as a hockey player. However, researchers at McGill University have done extensive studies on the biomechanics of skating on synthetic surfaces vs. skating on actual ice. To give you a brief synopsis of what they discovered in their study, they found that the coefficient of friction was slightly different between the two surfaces (higher on the treadmill) which possibly results in a slightly shorter glide phase on a treadmill, however, the actual mechanics of the forward stride were not significantly altered.

IS VIDEO ANALYSIS THE SAME AS MOTION CAPTURE?

No! Video analysis is significantly slower, depending on the type of camera you are using which means the amount of possible data you can even collect is instantly diminished. Our motion capture technology collects data at 240Hz, or we get 240 individual data points per second. A high rate of capture means increased precision in our calculations. Video analysis involves identifying joints and joint segments using a mouse in 2D which also incorporates a high degree of error and only allows you to analyze one frame. With 3D motion capture technology the exact location of each joint segment is calculated with minimal error and an average of each stride is taken to give a more accurate representation of the player’s biomechanics.
