This stage of adolescence is a period of bone development, especially in infancy and adolescence, and peak growth in boys from 10 to 13 to 18 to 20 years old. During periods of rapid bone growth, eating foods rich in calcium and vitamin D, as well as moderate exercise, is beneficial for bone growth. Adolescence and middle age: From age 20 to age 40, bone growth is relatively balanced and bone mass peaks. Between the ages of 30-35, bone density reaches its highest point in life. In the early stages of the peak, although the length of the bones stopped increasing, the strength still increased and the bone mass increased slowly.

During this phase, higher peak bone mass can be achieved with moderate exercise and adequate calcium and vitamin D intake. After age 35, bone mass begins to ease slightly. Middle-aged and old age: This stage is the period of bone aging. After a woman turns 50, her estrogen levels drop and bone mass begins to lose. After age 60, bone loss begins rapidly. In Western countries, the prevalence of osteoporosis in men over the age of 50 exceeds 20% and in women it exceeds 40%. Bones continue to be lost in old age. Hip, wrist and spine fractures often occur due to decreased bone mass.

About one in four people with hip fractures over the age of 50 will die from complications within a year, and about one in four will be bedridden for the rest of their lives. Supplementing calcium and vitamin D at this time is mainly to prevent a large loss of calcium in the body. Depending on the specific condition of the bones, osteoporosis therapeutic agents, ie, drugs that promote bone formation and inhibit bone fragmentation, may be applied. 60% of the bone weight during maturity is mineral, mainly composed of calcium salts. People who ate a diet that was adequate in calcium and vitamin D had higher levels than those who were deficient in bones. Endocrine hormones: Hormones such as sex hormones that affect cells in the body, growth hormone, and thyroid hormones, as well as hormones that regulate calcium and phosphorus metabolism, such as parathyroid hormone, calcitonin, and vitamin D derivatives, are involved in the regulation of peak bone mass, exercise And exercise has a positive effect on bones.

In the case of ensuring adequate calcium intake, physical activity can even exceed health conditions and habits: chronic metabolic disorders and serious diseases, long-term use of certain drugs such as glucocorticoids can reduce bone mass. Negative lifestyles such as smoking and excessive alcohol consumption can also negatively affect bone density.
