Twists Again

Try asking some nonyogis what they think happens in a yoga class, and at least one will answer that people get "all twisted up like a pretzel." In fact, we yogis do twist a lot in a well-rounded yoga practice: We twist while sitting, standing, and standing on our heads. Because there is such an intriguing variety of twists, you might guess that twists provide an abundance of benefits. And they do. There are physiological benefits to the circulatory system and internal organs, structural benefits to the musculoskeletal system, and focusing benefits to your consciousness.

Indian yoga master B.K.S. Iyengar describes twists as a "squeeze-and-soak" action: The organs are compressed during a twist, pushing out blood filled with metabolic by-products and toxins. When we release the twist, fresh blood flows in, carrying oxygen and the building blocks for tissue healing. So from the physiological standpoint, twists stimulate circulation and have a cleansing and refreshing effect on the torso organs and associated glands.

While these physiological benefits are undeniably valuable, this column will focus primarily on the functions of and benefits to muscles and joints used in twists. Yoga twists involve the spine, as well as several major joints, including the hips and shoulders. In fact, full range of motion in spinal rotation is essential to many yoga poses. Unfortunately, many people lose full spinal rotation in the course of living a sedentary lifestyle. Some losses can occur if joints fuse due to trauma, surgery, or arthritis, but most range of motion loss comes from the shortening of soft tissues. If you don't lengthen the muscles, tendons, ligaments, and fascia (connective tissues) to their full length at least a few times a week, they will gradually shorten and limit the nearby joint's mobility. In the case of twisting, the limitation is usually in soft tissues around the spine, abdomen, rib cage, and hips. If you regularly practice yoga twists, there are some clear benefits to these same joints and soft tissues. Not only do you maintain the normal length and resilience of the soft tissues, but you also help to maintain the health of the discs and facet joints (the small pair of joints on the back of the spine where each two vertebrae overlap).
