Fixing 5 Flaws in Your Running Form



If you're like me, just hearing the word "run" makes your skin crawl. Some people claim to find peace of mind on their daily jog. Are these people crazy, or have they just found some sacred running nirvana-type state? Well, if you work on your running technique, you will undoubtedly find that you will improve all of your times, and the whole process just might be a little bit less arduous!

Like a power clean or a deadlift, there a lot of technical nuances involved when sprinting or distance running. The fastest and most efficient runners are experts in perfecting their stride length, stride frequency, heart rate, and breathing patterns. All of these things work together to help you channel your inner Tyson Gay. Here are five of, what I deem to be, the most common technical errors in gait:
  1. You're striking with your heels first. Try something for me: jump up in the air, and then deliberately land on your heels first, rather than on your toes. How did that feel? Presumably, pretty awful. In one of my previous posts, I touched upon jumping mechanics. The author of Running Science, Owen Anderson notes, "...motion analysis of Olympic Games competitors has suggested that ... medalists are more likely to employ MFS (midfoot strike). In addition, video analysis of world-champion and world-record holding runners ... has indicated that such competitors employ MFS, and occasionally FFS (forefoot strike), but not RFS (rearfoot strike) while training and competing." It has been theorized that a RFS can place more stress on the knee joint and simultaneously increase breaking forces, which may decrease running economy. There appears to be a correlation between race times and MFS/FFS.
  2. You're leaning too far forward. As with standing posture, you're trying to maintain a nice vertical torso, and make yourself "tall." This means you shouldn't be hunched over like Quasimodo and looking at the pavement. While that may be ever-so-tempting once you get fatigued, you'll be more efficient staying upright. Worldrunning.com mentions that "[if] you have bad posture then your body will have to use up energy to keep you upright, which wastes energy you should be using to run faster and further."
  3. You're not moving your arms enough. Now, let me start by saying that you don't want to go overboard with arm movement, either. Ideally, it should be a relatively passive motion. Pumping your arms like crazy isn't necessarily going to make you a speed demon. On the other hand, I've seen some people who leave their arms to flop limp at their sides, which is equally as inefficient. The arms should be moving in sync with the legs (the left leg and right arm together, and the right leg and left arm together), allowing for a little bit of rotation in the hips. "The main function of your arms is not to drive the body forward but to provide balance and equilibrium as gravity pulls you forward," notes Dr. Nicholas Romanov, the founder of the Pose Method of running.
  4. Your knees are collapsing as you run. Running is a forward, linear movement, performed predominantly in the sagittal plane. Any forces that counteract that are going to result in unnecessary energy expenditure. Knees caving inward (valgus knees) are usually coupled with external rotation of the feet. Take a look at the the photo below of the sprinters. The two sprinters on the left are maintaining forward momentum, while the gentleman on the right has some internal rotation of the hip, as his foot externally rotates. With a little bit of hip strengthening, he could shave some seconds off of his split and lower his risk for injury.
  5. You're breathing incorrectly. Breathing in any activity is, to me, the most important determining factor of success. In an aerobic activity like a longer distance run, breathing should be a first priority. As you fatigue, you may have noticed that your breath becomes shorter and more rapid. Maybe you start wheezing like an asthmatic, and you're doing anything you can just to finish your run. Experienced runners, however, have mastered the rhythm of their breathing. While different coaches have numerous methods for the proper cadence of the breath, there are some aspects that are universal: you should aim to expand the ribcage and the belly as you breathe, rather than just the chest, and, your breath should remain relaxed rather than laborious. Both of these things can help you manage your heart rate and keep you running faster for a longer period of time!

Running doesn't have to be a miserable experience (although it'll never be a pastime I particularly enjoy...). If you correct your technique, you will minimize the amount of energy you waste with each stride, and maybe, just maybe, you'll find that elusive "runner's high" I've heard people mention in fables.
