Saw this one this morning ☝️the pectineus muscle is a small muscle in the front/inside part of the groin.
It’s a muscle that is part of the adductors that function to adduct (bring leg toward midline) as flex the hip.
Why do I see this strained in runners + athletes? 🤷♂️
Well when the affect leg is planted, you need good stability of the pelvis. The glutes are a big part of providing this stability, so hopefully they are activating properly ✅
The adductors in general tend to overwork due to lack of pelvic stability by the glutes.
Lack of glute/pelvic stability will create internal rotation of the hip, SHORTENING the pectineus.
An anterior pelvic tilt will also create excessive internal rotation and likely overload the adductors with LESS glute activation.
Try it out! I play around with this all the time when I’m working out on my own. Various positions of the pelvis will affect which muscles are activated. It’s very hard to get good glute activation when it an anteriorly tilted pelvis.
These are just some findings associated with strained adductors. I’m generalizing obviously, but you need to address tight muscles as well as strengthen the weak ones.. big picture, work on proper mechanics through your activity or sport 🤝
