I'm thinking if you are interested in running and injury you might find this worth a quick read. Nic Simpson shared this article with me this morning, which I found fascinating. Sado, et al., (2019) looked at the lumbosacral torques [lateral flexion (LF), extension (E) and axial rotation (AR)] at different running velocities.

They found that faster running required larger lumbosacral AR torque – that makes sense. Now this is the interesting part. The E and LF torques didn’t change much at running velocities above 7 m/s, however, they found the LF and E torques changed at velocities below 7 m/s, thinking this might increase biomechanical loading causing excessive pelvic posterior tilt and excessive pelvic drop. They concluded that this has the potential to cause pain/injury related to lumbopelvic extensors and lateral flexors.

When I saw this my mind started wondering how I'd load a vest to address these potential lumbopelvic problems at submaximal running velocities. I've talked previously about the role of wearable resistance in lumbopelvic conditioning whilst running, this another variation on that theme.
