Wellness Wednesday: Hamstrings
The hamstrings are a group of three muscles that extend from the Ischial Tuberosity of the hip (your sit bones) and the Tibia and Fibula (backs of your knees). The muscle group is comprised of the Biceps Femoris, Semitendinosus, and the Semimembranosus muscles. Combined, these muscles are primarily responsible for flexion of the knee joint as well as assisting the extension of the thigh. In addition to these functions the hamstring muscles work in tandem to rotate the knee, assist in maintaining a standing position with knees slightly bent as well as limiting how far we can bend forward as we try to touch our toes without bending our knees.
This muscle group is one of the more frequently injured in sports. If you’re an athlete, or a weekend warrior who likes to run fast, jump high, and train hard, your hamstrings are at risk. If you’re a desk jockey who spends most of his/her day sitting at a computer, you may be even worse off, especially if you’re planning to get in shape or be more active again. Finally, if you’re a gym rat who’s long made the mistake of focusing your leg training on the fronts of your thighs—hitting the hammies as an afterthought—you’ve already lit the fuse that can lead to a hamstring blowout.
Hamstring strains or “pulls” are usually non-contact injuries. Hamstring strains are typically caused by decreased flexibility, decreased strength, muscle fatigue and an inadequate warm-up. A hamstring strain can occur in a variety of ways. This muscle group is often injured in high-speed activities like running, jumping, pivoting or exploding out of a stance. Since the hamstring crosses multiple joints, it’s involved in motions or affects movement at each of these joints. Although its primary influence centers on the hip and knee joints, the hamstrings can easily impact back alignment and function.
You want to be sure to warm up your hamstrings before workouts. Some stretches to consider:
1. Lying L Sit
2. Supine “Active” Leg Extension
3. Seated twisting hamstring stretch
4. Lying hamstring stretch using a strap
5. Sitting hamstring stretch
