Back Strength and Running

This is the third blog post in a series about how each major muscle group in your body plays a role in your running. Runners definitely don’t want a bulky upper body to weigh them down, but our upper body plays a significant role in our running form and our efficiency. If you don’t pay attention to muscle groups other than the legs, you set the stage for injuries both up and down the kinetic chain. Our muscles don’t work in isolation.
Strength in our back is not only important in running but in daily life. Many people who sit for long durations of time at their job inevitably develop back pain. As a runner it is important to have strength in your mid and lower back to stabilize the spin and pelvis. A strong back is able to evenly distribute the force of you hitting the ground with each foot plant because of this even distribution of force you are less likely to suffer an injury. Back strength also contributes to maintaining good running form without over rotation, and, as we know, good running form, not only reduces injury risk, but it increases running efficiency (are we catching the theme here from the last two posts?).
As you increase your miles a strong back becomes more important because the increase means you will be running farther while your body is tired. This is also true for ultrarunners who train with back to back long runs. Soft tissues break down as we run and there are two things you need to do to reduce this and to help your body recover. First is rest. Make sure you are getting enough sleep, only increase your miles by 10% a week, and every fourth week reduce your miles by 20-25%. The second is strength. Soft tissue breakdown in your back can lead to injuries, especially in your hips and lower legs.
Over rotation of your torso due to a weak upper body causes your hips and legs to turn as well. They need to maintain a forward motion. A weak lower back also puts extra strain on your hamstrings, which can alter your stride and cause injuries in your hips, knees, and ankles.
Using high repetitions and low weight will help prevent building bulky shoulders. If theses are too easy for you, increase repetitions and keep the weight as low as you can. If these are too hard, lower the weight and then the repetitions as needed. By the end of the third set you should feel a burn in your shoulders and it should be difficult to perform the last repetitions.
Here are some exercises to help increase your mid and low back strength. Back extensions three repetitions hold for 15-45 seconds. Planks three repetitions 15-60 seconds. Bird dogs three sets 10-12 repetitions hold for 3-5 seconds at the top
How to perform back extensions: lay on your belly and lift your legs and upper body, hold it.
How to perform planks: get into the beginning push up position and hold. Your stomach should be held tight and your back straight. You can also lower yourself on your forearms.
How to perform bird dogs: get on your hands and knees lift your right arm and left leg straight out. Do the same thing with the left arm and right leg.
Adding strength workouts to your training program can be difficult because you just want to run and it can be hard to find the time. Keep in mind the first goal is to make sure you keep running and strength will help prevent injuries.
