When it comes to running, experts suggest avoiding static stretching

Stretching was once the cure-all for running injuries. Practitioners would ask injured runners if they were stretching enough, and if the answer was no they would offer more stretches. However, research is now suggesting that certain kinds of stretching aren’t great for runners, and may even be harmful for those who are prone to injury.

According to a literature review of several studies, there’s actually a correlation between lower levels of flexibility and better running economy, which refers to the amount of energy expended to maintain a particular speed. A study on untrained runners found that participants with the lowest flexibility happened to have the most naturally economic running styles. Researchers believe that this was a result of low range of motion, leading to better stabilization when the foot hits the ground. Basically, excessive range of motion means more energy is needed to stabilize muscles, and having a lower range of motion reduces that use of energy.

Carla Robbins is the owner of Vital Strength and Physiology in Calgary, Alta. She says she almost never prescribes static stretching to her clients – she’s all about strength work. “If stretching is something you do frequently, it’s technically possible to get more length in the muscle, but I don’t personally recommend it. I feel like there are other things that can check that box, for example, dynamic stretching or strength training. Strength training results in strength (and length), while also preventing injury.”

When to stretch.- If static stretching (holding one position) isn’t recommended for runners, then what should they be doing to warm up? Robbins says ideally runners will integrate dynamic stretching (not holding the stretch, but moving with control in and out of the end ranges of the stretch) into their pre-run routine. A dynamic warmup will increase body temperature, which activates enzymes that are beneficial to running.

When not Stretching.- Robbins says static stretching should be avoided by runners who are trying to prevent (or rehabilitate) an injury. “There isn’t enough evidence to support that stretching prevents injury,” she explains. “Some stiffness is required in the ligaments and muscles to run. For example, if you’re a hyper-mobile person with relaxed ligaments, you might be more prone to injury as your joints are more likely to move with loading. Lack of stiffness isn’t necessarily beneficial.”

Robbins also reminds runners never to stretch through pain. “Listen to your body, it’ll tell you if you’re doing something wrong.”

When runners cramp up, many feel the need to “stretch it out,” but the research is divided on the topic. Muscle cramps can be caused by many factors including dehydration, fatigue and vitamin or mineral deficiencies. Leg cramps can also be a side effect of some prescription medications.

However, the reason for cramping and its exact cure eludes us. Several studies suggest that stretching out a cramp won’t hurt you, but it won’t necessarily help, either. If cramping is an issue for you, Hyland’s Leg Cramp Tablets, an official sponsor of the Boston Marathon, are one way to feel confident on the start line. Hyland’s Leg Cramps Tablets are taken without water, the quick dissolving tablets melt instantly in your mouth for fast-acting natural relief of leg, calf and foot cramps with no known side effects.

When strength training, runners should pay special attention to their quads and hamstrings, along with ankle and hip mobility. These are the areas where the most-common running injuries tend to happen.
