Harvard Health Publications calls T’ai-Chi “Medication in Motion”!

Tai chi is often described as “meditation in motion,” but it might well be called “medication in motion.” There is growing evidence that this mind-body practice, which originated in China as a martial art, has value in treating or preventing many health problems.

Tai chi is easy to learn and you can get started even if you aren’t in top shape or the best of health. In this low-impact, slow-motion exercise, you go without pausing through a series of motions named for animal actions or martial arts moves. As you move, you breathe deeply and naturally, focusing your attention — as in some kinds of meditation — on your bodily sensations.

Tai chi differs from other types of exercise in several ways. The movements are never forced, the muscles are relaxed rather than tensed, the joints are not fully extended or bent, and connective tissues are not stretched. Tai chi can be easily adapted for anyone, from the most fit to people confined to wheelchairs or recovering from surgery.

Tai chi in motion:

A tai chi class might include these parts:Warm-up. Easy motions, such as shoulder circles, turning the head from side to side, or rocking back and forth, help you to loosen your muscles and joints and focus on your breath and body.

Instruction and practice of tai chi forms:

Short forms — forms are sets of movements — may include a dozen or fewer movements; long forms may include hundreds. Different styles require smaller or larger movements. A short form with smaller, slower movements is usually recommended at the beginning, especially if you’re older or not in good condition.

Qigong (or chi kung):

Translated as “breath work” or “energy work,” this consists of a few minutes of gentle breathing sometimes combined with movement. The idea is to help relax the mind and mobilize the body’s energy. Qigong may be practiced standing, sitting, or lying down.

No pain, big gains:

Although tai chi is slow and gentle and doesn’t leave you breathless, it addresses the key components of fitness — muscle strength, flexibility, balance, and, to a lesser degree, aerobic conditioning.

Here’s some of the evidence:

Muscle strength:

In a 2006 study published in Alternative Therapies in Health and Medicine, Stanford University researchers reported benefits of tai chi in 39 women and men, average age 66, with below-average fitness and at least one cardiovascular risk factor. After taking 36 tai chi classes in 12 weeks, they showed improvement in both lower-body strength and upper-body strength. In a Japanese study using the same strength measures, 113 older adults were assigned to different 12-week exercise programs, including tai chi, brisk walking, and resistance training. People who did tai chi improved more than 30% in lower-body strength and 25% in arm strength — almost as much as those who participated in resistance training, and more than those assigned to brisk walking.“Although you aren’t working with weights or resistance bands, the unsupported arm exercise involved in tai chi strengthens your upper body,” says internist Dr. Gloria Yeh, an assistant professor at Harvard Medical School. “Tai chi strengthens both the lower and upper extremities and also the core muscles of the back and abdomen.”

Flexibility:

Women in the 2006 Stanford study significantly boosted upper- and lower-body flexibility as well as strength.

Balance:

Tai chi improves balance and, according to some studies, reduces falls.

Proprioception:

— the ability to sense the position of one’s body in space — declines with age. Tai chi helps train this sense, which is a function of sensory neurons in the inner ear and stretch receptors in the muscles and ligaments. Tai chi also improves muscle strength and flexibility, which makes it easier to recover from a stumble.

Aerobic conditioning:

Depending on the speed and size of the movements, tai chi can provide some aerobic benefits. But in the Japanese study, only participants assigned to brisk walking gained much aerobic fitness. If your clinician advises a more intense cardio workout with a higher heart rate than tai chi can offer, you may need something more aerobic as well.
