Most runners want to get the most out of each stride they take with the least amount of effort on their part. In order to accomplish that desire I like to start by teaching individuals how to develop efficient running mechanics. Learning to run with proper technique generally means a person can run longer and run safer. Here are four priorities for efficient running mechanics.
Stride angle is the angle formed by your thighs at toe off. In the world of efficient form, we like to see this angle as large as possible. Most professional runners have a stride angle of 80 degrees or larger. However, in recreational runners a stride angle between 60 to 65 degrees is considered adequate.
Improved stride angle is accomplished through two key modifications:
Simple running drills like uphill repetitions, high knees, butt kickers and high skips will help to increase stride angle.
Arm carriage is one of the most important components to consider in developing efficient running mechanics since what happens in the upper body affects motions in the lower body. The good news is that correcting arm carriage is one of the easiest things to change. Three things to keep in mind:
The faster you run, the higher your hands will travel. However, regardless of how fast you’re running your arm movements should always come from the shoulder and follow the same directional path regardless of how high they drive. The most important thing is not allowing the hands to cross the midline of the body. Crossing over causes additional rotational motions throughout the body. Those rotation movements decrease running economy and may lead to common running injuries.
Foot strike positioning and habits have been extensively discussed in the world of running. Many coaches teach that mid-foot placement is a must. However, this isn’t always the case. If an athlete has a good shank (lower leg) angle upon contact, it’s equally safe and efficient for initial contact to take place at the heel or the mid foot. An ideal shank angle is when the lower leg, or shin, is perpendicular to the running surface upon contact. When shank angle is adequate a runner will strike the ground while the foot is already moving in a rearward direction and slightly in front of the body’s center of mass. The knee will also be slightly flexed in order to safely absorb impact forces. Because of the tendency for some heel strikers to contact the ground with a rigid knee heel striking has been given a bad rap.
Another important component to foot strike is step width. Your feet shouldn’t cross the midline of your body at any time. Because the upper and lower body counterbalance one another, cross over in the feet may lead to cross over in the arms. The benefit to the counterbalancing act is that working on linear arm carriage (which as mentioned above, is one of the easiest things to address) tends to improve a narrow step width position.
One last consideration in foot strike is pronation and supination. Pronation and supination refer to the outward and inward motions of the foot throughout foot strike, the support phase and toe off. Some pronation and supination are expected and are efficient. Upon initial contact a runner will strike the ground more on the outside of their foot (supinated). As the foot rolls inward (pronation) the foot is able to absorb forces and prepare for propulsion at toe off. With adequate pronation a runner can evenly push off from the front of their foot. Because specific running shoes and orthotics have been made to help control the amount of pronation and supination a runner may achieve, many runners who tend to have excess outward and inward movement find relief by trying a different shoe or an inexpensive orthotic.
The mid-section or trunk, pelvis and hips are vital to efficient running mechanics. The mid-section is the connector between the upper body and the lower body and is responsible for controlling and eliminating excessive trunk rotation. The core of the body is also key to increasing the amount of force runners develop to propel themselves forward. Finally, stability in the trunk, pelvis and hips is essential to decreasing the risk of common running injuries. Keys to mid-section stability are strength and range of motion within the hips, muscular strength in the back and sturdy lower abdominals.
A runner’s trunk should be more upright during the push off phase of the gait cycle. This is often referred to as running tall or running proud. During the support phase, the upper body or trunk will be in a more forward position. Changes from 2 to 6 degrees in the trunk are considered common and efficient.
The pelvis should be neutral and stable throughout the entire gait cycle. This is best accomplished through core strengthening exercises with the pelvis in the neutral position during each repetition. Finally, the hips should be strong and flexible for adequate range of motion and to eliminate excessive motions that are inefficient.
Thinking about these four concepts and adapting where necessary will make any runner more efficient. Supplementing with proper strength and range of motion exercises will also aid in developing new patterns safely and more quickly. Remember, running is a skilled movement pattern that should be evaluated on occasion no matter how talented or how experienced of a runner you are.
