I’ve started looking at movement efficiency in terms of of leakiness and looking for where athletes are losing power, time, or speed through a leak or deficiency in their movement. If you’ve ever had the opportunity to do or observe technical intervention with an athlete using a force platform (or perhaps even 3D motion capture and analysis tools) you will understand this concept quite clearly. Race car engineers likewise understand this concept quite clearly. We can enhance performance by building a bigger engine (in some cases metabolic, in others literally a stronger more powerful athlete) but if the athlete’s movement efficiency is leaky they’ll lose out to their lesser peers.
