Should I Stretch Before or After My Run?

by Dorothy CoheeLeave a Comment

We all have seen, or have been, runners bending over to touch their toes or pull their foot back to stretch before a race. Therefore, it may surprise you that some research does not support static stretching prior to running, but at the same time others indicate it has no detrimental effects on performance.

However, research is unclear. These are a slew of small studies reporting dynamic stretching is best prior to running, especially for short distances, while others report static stretching has no detrimental effects on distance running economy or performance.

What Does Research Tell Us?

There is definitely conflicting information regarding dynamic stretching versus static stretching prior to running.

Scientifically, static stretching activates a protective neuromuscular reflex that tries to prevent muscles from being overstretched. After static stretching, muscles are unable to contract as forcefully and efficiently because they become inhibited by the brain. Efficiency actually requires an amount of stiffness in the leg when the foot makes contact with the ground for running in order to absorb the ground reaction forces and spring the body forward.

Dynamic stretching is performed quickly (2-3 seconds) and not held for a long duration of time, like with static stretching (15-60 seconds). Studies1 have found that a dynamic stretching warm-up can lead to improved performance by prolonging the time to exhaustion and it was able to be held over a longer duration. The dynamic warm-up increases the stretch-shortening cycle, especially for fast stretch-shortening cycle performances, due to the quick movements that are performed with the specific warm-up2.

A small study indicates the acute effects of static stretching prior to a long distance run, 60 minutes, has no effect on calorie expenditure, running economy, or endurance performance in women3. However, some of these studies look at sub-maximal performance using a very small subject group, in which not all motor units within a muscle are recruited4.

What is My Take on All This?

As you read, there is conflicting information when looking at research. However, the research contains very small numbers and therefore it is difficult to generalize the results to the general running population.

Dynamic stretching includes quick movements like skips, strides, high knees, butt kicks, grapevine, and the like. These provide a means to warm-up the heart and muscles prior to the workout or race. In addition, a dynamic warm-up provides the means to recruit all motor units and still maintain sufficient stiffness to enhance ones performance and allow the body to absorb the forces.

Static stretching for runners includes holding a stretch for at least 30 seconds to decrease muscle tightness and tension. These usually focus on the calf muscles, hamstring, quadriceps, hip flexors, and glutes in runners. Static stretching may assist with recovery and make your legs feel better following a run.

Stretching can be beneficial in protecting your body from injury. That said, it is important that you pay attention to any unusual aches and pains you experience after running. If this occurs, make sure to schedule an appointment at your nearest Athletico location before the pain gets worse.
