I've been running more frequently and it's been absolute murder on my hips. Anybody got any anti-hip hurting advice / stretches?
it's preferrable to perform dynamic stretches before running, and static stretches after running.
by dynamic, i mean gentle stretches through a full range of motion - no bouncing or pulling - things like cat / cow (exhale on the cat, inhale on the cow), hip rotations (in both directions), and lunges (keep your hips level and squared).
by static, i mean holding the stretch just shy of the point of tension for about 30 seconds, then using your breath to allow you to deepen the stretch after the muscles "release". this is something that should be done either seated or supine, while keeping your hips level. suggested stretches include (seated) butterflies, straddles, and forward folds, and (supine) figure fours and knee drops, both cross-body and same-side. use a block or a small, firm pillow if there is space between how far you can comfortably stretch and the floor. if you need detailed instructions, let me know.
How important is a high cadence? The 180 number is thrown around a lot, but I feel like I'm running on the spot and sacrifice speed to reach that level. Does it help reduce the risk of injury from impacts?
unless you're an elite runner with years of training, cadence is significantly less important than form.
to answer your question, no. the more often that your feet hit the ground, the higher the risk of injury.
that risk is best mitigated with proper nutrition, proper conditioning, proper form, and proper footwear.
10km a day my k-words, today is 182 apparently. Road running, particularly long efforts up to and past 20km can leave my hip flexors feeling very strained, anyone got any stretches or tips?
that's impressive!
i would suggest the same variety of stretching above, with additional consideration for your conditioning ...
runners often have very strong anterior (front of the body) muscles, with weaker posterior (back of the body) muscles, especially in the core. developing muscular balance usually involves strengthening the accessory core muscles (specifcally, the obliques), the smaller muscles in the spine, the gluteal muscles, and the hip adductors and abductors (the muscles that allow you to bring your thighs together or apart), as well as stretching those well-developed anterior muscles (specifically, rectus abdominus, pectineus, psoas, and iliacus).
even if you're averse to yoga, consider incorporating some of the poses into your stretching, as they will probably be tremendously helpful. i would suggest cat / cow, upward dog, wheel (full or half), pigeon, and happy baby.
