Osteoporosis has become the most common metabolic bone disorders [1, 2]. Osteoporosis is “a skeletal disorder characterized by compromised bone strength, predisposing to an increased risk of fracture”.
There is over millions of individual suffering from osteoporosis or having low bone mass worldwide. Treatment of osteoporosis involves using either antiresorption agents or bone formation agents. There are complementary therapies that are considered to be safer, are more popular. These complementary therapies include weight bearing exercise, herbal medicine, massage, relaxation techniques and tai chi.
We will look into the scientific approach behind Tai Chi as a complementary therapy for osteoporosis.
Many of the women in their late forties and fifties are either not willing or unable to engage in regular high impact exercise. They are actually in a fast bone loss phase of their lives, when efforts to slow bone loss are actually very important.
Tai Chi provides a good form of weight bearing exercise, since it emphasizes a lot on the weight transfer of the body natural weight. In Tai Chi, you perform a series of slow, rhythmic and graceful controlled body movements while your body remains erect and anatomically aligned (Figure 1 & Figure 2).
By doing so, we activate the agonist/ antagonist/ synergist muscles in the correct firing sequence to support body mass in the direction of gravity. Muscle operating eccentrically create stress on the bone; the phenomenon of resistance training.
The intensity of the weight bearing exercise in Tai Chi is increased by either lowering of the posture or including weights during the Tai Chi practice. In this way, the bones will be forced to work even harder and more effective. Proper guidance and monitoring by professionally well trained Tai Chi coaches is strongly recommended for such high intensity Tai Chi weight bearing training. Sufficient calcium & vitamin D intake is also necessary in conjunction to the Tai Chi weight bearing exercise.[6]
Unlike many other forms of exercise, Tai Chi is suitable to people of all age, gender and races. In fact, Tai Chi is particularly beneficial to the elderly and people with impaired motor skills since Tai Chi emphasizes correct posture alignment and balance, the exercise may be a safer alternative for women with fragile bones than other high impact physical activities.
The specific exercises create sufficient loading on the bones (bone re-modeling), and do not create unnecessary stress on the joints through improper posture misalignment (e.g. Figure 3).
When coupled with the right intensity of Tai Chi training, together with correct postural alignment and the activation of the eccentric strength, it will then result in the optimal effectiveness of improving overall bone mass.
