Bone mass generally peaks around the age of 30-35, and then starts to slowly decline at around age 50 in women (60 in men) when you start to lose bone mass faster than your body can grow it back. This happens to all adults, however critical loss of bone mass (osteoporosis) is much more common in women.
People reach peak muscle mass in their 20s and start losing muscle in their 40s - at a rate of 7 to 8 per cent per decade, he said. The rate of muscle loss doubles to about 15 per cent each decade after the age of 70. Once we reach 70 years old, we can expect to have lost about 25 per cent of our muscle mass as part of the ageing process, said Dr Chew. Skeletal muscles, which are attached to bones, are the most likely to weaken.
