We've previously posted on the often-underappreciated function the hip adductors serve during running here. They assist a number of other muscles including the hamstrings, hip flexors, calves & core muscles. So how strong do they need to be?
Here are a couple of tests to assess hip adduction strength:
1. Copenhagen bridge hold
🔎How to perform: In the side plank position, have your top leg resting on top of a table/chair 30-40cm from the ground, with your bottom leg underneath so all your weight is on the top leg.
🎯Normal result: 40+ seconds, less than 10% difference side to side
2. Hip adduction with hand-held dyno
🔎How to perform: Using a hand-held dynamometer, have the runner on the side, & have them push up as hard as they can with the underside leg.
🎯Normal result: Males= 31% body weight, Females= 22% body weight
In a future post, we will discuss how to strengthen them!
👋Runners, let us know how you went & save this post for future reference!
