If you're a fan of sports than that usually means you're a fan of speed. Speed is usually what's featured on the 'play of the day' for the sports broadcast. And the higher the level of sport you achieve the faster the game becomes.Now of course there are exceptions to this rule. Gretzky would be one for sure. He definitely wasn't the fastest guy in the league. Or his team. Heck, he probably wasn't even the fastest on his line. But for what he lacked in speed he made up with great vision, a competitive spirit and a sense of where to be on the ice.[caption id="attachment_4995" align="aligncenter" width="300"] The Great One was not the fastest one.But back to the discussion of speed usually new coaches learn there are a couple of ways to make an athlete faster. You can:A. increase stride rate or how quickly you can turn the limbs overB. increase stride length or how much horizontal distance can be covered with each strideWhen a coach considers these two options for increasing speed they will sometimes seek out drills and exercises to improve in these two areas. To improve stride rate there is an emphasis on being able to produce force at a higher rate. Think of things like jumps, hops, bounds, med ball throws and Olympic lifts and you'll get the idea. These exercises usually involve extension at the ankle-knee-hip with an explosive effort.To improve stride length sometimes this is approached as either a strength or mobility issue. Or both. If an athlete lacks strength they wouldn't be able to propel themselves effectively from one position on the ground to another. Or maybe they have adequate strength but lack mobility at the hip preventing optimal range of motion through the gait cycle.Attacking speed improvement from either of these...
