Appearances are deceiving. What often appears to be short, choppy strides are actually covering a lot of ground because the runner is striking the ground with such force that they are being propelled up and forward, covering sufficient space to achieve a high velocity. Bolt has both; great power and long legs. Football players and short-race sprinters (<
60m) definitely want to maximize stride frequency, but 100m and up requires great stride length also.
