According to Brian Mackenzie for Sports Coach, the skeletal system responds to exercise by increasing the strength and flexibility of muscles. Exercising regularly improves body balance and muscle tone and eases pressure within joints. This reduces the risk of diseases within the skeletal and muscular systems.
Exercise causes mechanical stresses within the skeletal system. This involves skeletal muscle pulling at insertion and origin points, leading to an increase in bone size and density at these areas. Significant impact of exercise on the skeletal system is reported among weight lifters, endurance athletes and soccer players, notes Mackenzie.
Immobilization of body parts in cases of fracture injuries leads to reduction in bone density. This is caused by lack of mechanical stress on the skeletal system. Exercising reduces susceptibility to bone fractures because it strengthens the soft tissues that support the skeletal system. Exercising among children should be monitored because a child's developing bones cannot withstand a lot of mechanical stress. Exercising without taking enough vitamin D and calcium leads to loss of bone density. Aging also affects the skeletal systems through calcium loss leading to osteoporosis. According to Mackenzie, it is important to consult a doctor before starting an exercise program to prevent injury to the skeletal system.
