I'm Jeremy Shore for LIVESTRONG.COM, and this is how to prevent pulled muscles in the calves from running. The first thing you need to make sure that you do is stay properly hydrated. And also, add an electrolyte supplement on those high-mileage days. The next thing to do is to integrate foam rolling and dynamic stretching in the lower body. This will help shore up your lower body and help prepare it for movement, and prevent straining or pulling a calf muscles. Let me show you how to do this. First, we'll target the lower leg, the calf complex, by positioning it just below the larger portion of the gastroc into the soleus. Place your hands behind you, and cross the other leg on top to add some additional compression. Slightly lift your weight off the ground with your hands, and in controlled movement, push and pull, rolling through the calf complex. Take deep nasal breaths as you perform this movement. Roll for about 10 passes, and then switch legs. Next, take advantage of this new range of motion by incorporating a dynamic calf stretch. Get into a push-up position up on your toes and hands. From here, push through your hands, driving your heels into the ground, tucking your head between your arms, and then do a calf raise as you push yourself back into that push-up position. Repeat for approximately 10 repetitions. And the next, finish with a basic leg swing. Stand tall, push your hands on your hips, take your weight onto one foot with a slightly bent knee, and then bring the foot back towards the glute and then kick through, swinging the leg. Do 10 repetitions, and then switch sides, staying tall, getting a full range of motion. Do not excessively arch your low back. This has been how to prevent pulled calf muscles when running.
