Giving your hips some love and attention will make you a more powerful runner and future-proof you against injury by Lisa Buckingham for Women’s Running Jan ’19 issue
Your hips and pelvis work together as the foundation for your spine above and for the legs beneath them, and the muscles, ligaments and tendons surrounding them play a hugely important role for runners.
This includes the hip flexors that run down the front of the hip, which lift the knee and bring your thigh upwards during the swing phase, but also muscles that you wouldn’t necessarily associate with your hips. These are the quadriceps, which insert into the hips, and the gluteal muscles in your buttocks – gluteus minimus, medius and maximus – which help keep your hips and pelvis level as you run.
When you run, your hips have to work much harder compared to when you’re just walking. This is because your weight is only ever on one leg at a time (this is known as the stance phase). “Along with the powerful forward drive of running, your hips provide all of the support during the stance phase,” says Rachel McCulloch,consultant rehab physiotherapist at Six Physio (sixphysio.com)
Injury hot spot
Put simply, if they’re not working properly, it can increase your risk of injury – and not just in the hip. A recent study in the American Journal of Sports Medicine showed that contralateral pelvic drop (CPD) was the strongest predictor for soft-tissue running injuries in the leg, such as iliotibial band syndrome, Achilles tendinopathy and patellofemoral pain. The study found that for every 1° increase in pelvic drop, there was an 80 per cent increase in the odds of the runner being classified as injured.
CPD happens when you don’t keep your pelvis and hips level as you run and it’s also known as the Trendelenberg gait. As you land on one foot, your weight-bearing hip pops out to the side, and the opposite hip drops down. Google a video of someone doing it and you’ll recognise it instantly as so many runners are guilty of doing this.
“I see it in about three quarters of the runners in my clinic,” says Rachel. “It can increase risk of injury because it creates unnatural planes of movement further down the leg. For example, the sideways movement of pelvic drop can create a diagonal movement in the knees, which are not equipped to deal with this. Your ankles, feet and lower back can also be affected.
“Dysfunctional hip movement also reduces running economy, which means that the effort you’re putting in is not equalled by your output.”
Build hip strength
To check if you’re prone to CPD, ask a friend to video you running from behind – wear close-fitting, bright clothes so that you can see your body shape. Then check online videos for reference when you review the footage. Whether you need to correct CPD or not, there’s plenty you can do to improve strength and stability around your hips and pelvis and become a faster, less injury-prone runner:
