Sarcopenia is an important cause of frailty, physical disability, falls, fractures and even hospitalisation. Ageing is regarded as the main cause for gradual loss of tissue and organ dysfunction over time. As we age, we begin to lose one-tenth to one-half per cent of muscle mass every year, starting in the age of 30s. This loss accelerates in the age of 50s, with a muscle loss of one to two per cent every year. This age-related loss of muscle mass, strength and power is called sarcopenia..Yoga asanas are one of the few physical exercises that can be continued as one ages. Regular practice of yoga might help one age better. Yoga asanas are low impact moves that maintain the tone of the muscles and also flexibility at old age when joint stiffness is a major concern.
