Sprinter's Symptoms and Solutions

by Chris Korfist

I love listening to coaches at track meets. In the excitement of the race or after a race, trying to give their athletes a tip as to how to improve, I often hear coaches talk to their athletes about various aspects of running that they need to improve upon. Cues like they need to stand up more, dorsi-flex their foot or even get up on their toes seem to pop up. I also like to watch the coaches urge their runners to use their arms better by pumping their arms to get them to do the same. However, what these coaches don’t understand is that as many cues as they give their athletes, the athletes cannot execute what their coach asks of them. They simply lack some form of strength to be able to do so. So while they try, they just can’t. What would be more beneficial for the coach and the athlete is to learn the cause of the poor running form.

The number one problem that I see in most runners is that they are push runners. My definition of a push runner is one who uses their quadriceps to propel or push their body in a linear direction. I am not sure why this tends to be so prevalent with sprinters. However, after seeing many people who play different sports, I see football players push more than other sports. So, I would guess that it is due to the football programs strong desire to squat as much as possible which often results in some type of half squat which focuses on the quads rather than the posterior chain. Becomes the quads becomes so strong, they assume the role as the mover because the posterior chain does not have the strength to do so. When the quads propel the body, various characteristics will show in the runners form. The easiest to spot is a bend at the waist.(Video 1) A runner’s butt will also stick out.(video2) They will also be slightly curved in the torso.(video 3) This is so they can put their body in the position to do quarter squats to push their body down the track. Watching the video, it will look like the runner is jumping the sprints. (video 4) He will have a pronounced bounce on video. (video 5) In fact, ask an athlete who has to run and catch a ball what the ball does when they are running. If they say it looks like it is moving, they are probably a push runner.

Also, the contact point of the foot on the ground is important. Usually, when a sprinter has the above-mentioned characteristics, they will have a foot strike that is in front of their center of gravity with a bent knee compared to a straight leg. (pictures 1&2) This is an indication that the sprinter lacks “kick out” or their ability to straighten their leg before they snap down, which forces the athlete to use his posterior chain to move.

All of this results from having a weak posterior chain. So when you tell a runner to stand up tall when they sprint, they cannot do it because they are too weak to do so. When you tell them to paw the ground, they can’t because they are too weak. Their hamstrings cannot take the force so they pass it off to more powerful muscles. So to take care of the problem, it would be wise to start implementing more posterior chain type exercises. First, to get them strong through a strength phase using Glute Ham raises, Reverse Hypers, Split Squats, HF Squats, Stiff leg deadlifts and Romanian Deadlifts. From there go into a power template by making your exercises reactive in nature. In my opinion, the kings of posterior chain runners are Reactive Glute ham Raises, 4 way hip machine and Prime time runs. I like Reactive Glute Hams because they develope the kick out. I like the 4 way hip because you can’t push. It forces the posterior chain to pull and shuts off the quads. It also helps develop extensibility, which is flexibility under force. Lastly, Prime Time runs are 4 way hip machine in action. It ties the movements together so the body realizes how it is suppose to move. Let’s not forget the entire series of ADA drops and RA jumps either. Plantar Flexor drops are great, as are split squats. Both are important for the absorption and toe off acceleration. I will get to these exercises in the next article.
