Daily physical activity helps to prevent osteoporosis and osteoarthritis
Explanation:
Osteoporosis is a disease caused by the loss of bone density, making bones fragile and more likely to break, while arthritis can be defined as the inflammation of the joints, which may be caused by the breaking of the bones. The most severe type of arthritis is osteoarthritis. Physical exercise helps to slow the rate of bone loss, thereby it is possible to prevent bone diseases such as osteoporosis and osteoarthritis by making regular physical activity, reducing thus the risk of bone fractures. Moreover, physical activity may also help to maintain muscles that work together with the bones to support every movement. It is also important to highlight that healthy food habits such as, for example, adequate daily consumption of vitamin D and calcium can also help to prevent bone loss.
D: fully moving muscles without locking your joint.
