LISLE TRACK STARTING BLOCK PHILOSOPHY Nothing confuses young sprinters more than starting blocks. They often don’t know how they “work,” how to set them, or why a specific setting is best for them. It’s not all that complicated. Even parlympians without feet can figure it out! Years ago when tracks were dirt, sprinters used trowels to dig out holes for their feet. As track surfaces improved, digging holes was no longer practical. Starting blocks “work” by giving the sprinter a means to apply horizontal force against a fixed surface—that surface being the PEDALS of the blocks, which are fixed by spikes to the track. Setting the pedals involves nothing more than determining the right spacing that will help each sprinter achieve the proper angles at the knee and hip to achieve the best possible start. This needs to be different for each sprinter, because each sprinter has different limb lengths. We determine the best setting for each sprinter by measuring five specific points: Back Length Upper Leg Length Lower Leg Length Arm Length Foot Length We then put this data into a table, which will give the athlete the following information: • Distance from the first pedal to the starting line • Distance between the first pedal and the back pedal • Angle to set the front pedal and the back pedal What we do differently: Lisle has the best starting blocks in track and field—the NEWTON ELITE. These blocks have an optimal pedal curvature, as well as an angle adjustment feature. Why is this important? Even though forces seem to be predominantly horizontal, sprinters in a set position are still experiencing the effects of gravity. For example, in the start, the horizontal forces are about 205 pounds. The vertical forces are 277 pounds. It’s not “all” horizontal force as many would think. And at top speed, it’s 50 pounds horizontal and 367 pounds vertical. GRAVITY--in terms of staying upright-is important even coming out of the blocks! Both the curved pedals and the ability to adjust the angles of these pedals gives the sprinter a better means to deal with the effects of gravity. The curvature of the pedal also allows for more of the front part of the foot to contact the track. This enables the sprinter to achieve a better “up and out” position. “Up and Out” means a more optimal position to negate stumbling, a big problem for younger sprinters. What we teach: • High Bridge with the fingers (no “handcakes” (meaning palms flat on the track.) • Hips up in the set, head down, and eyes down The sprinter’s fastest reaction is always to sound, not “sight” No need to look up or forward. This will immediately change the angles at the hip and knee. What my research going back to the mid seventies determined. In the traditional “crouch” start the sprinter is too low. But in the standing start, the sprinter is too high. Somehow, we need to manipulate whatever factors we can to provide the best start for our athletes. NOTE THE GREEN ANGLE—UP AND OUT This image is from testing I did for an article entitled “Re-Evaluating the Conventional Crouch Start” Note one of the earlier LED electronic stopwatches connected by wires to sensor pads on the block pedals! WHAT SHOULD I BE THINKING ABOUT? THINK “BIG PICTURE” FIRST. TO ACCELERATE WELL, YOU NEED TO APPLY FORCE. VERTICAL BLOCK FORCES Remember that vertical effort in the start is stressed because of the GRAVITY HANDICAP. Revising Vertical Force Requirements because of gravity means that you will be exerting about 277 pounds of force. YOU CAN IMPROVE YOUR ABILITY TO APPLY PRODUCTIVE FORCES BY 1) REDUCING YOUR BODY MASS 2) GETTING STRONGER WE ACCOMPLISH THIS THROUGH 1) GRAVITY CONSTANT 2) DEADLIFT STRENGTH PROTOCOL
