Swimming and hiking are both great aerobic exercises. Whether it's swimming or hiking, middle-aged and elderly people should grasp a good degree of appropriate exercise is advocated, but excessive, frequent exercise is to increase the body's consumption. Under the premise of regular, moderate exercise, swimming should be more suitable for middle-aged and elderly people to carry out sports.
First, it reduces joint injuries. Compared with climbing, swimming can reduce limb joint damage, but also can increase the activity of spinal joints, so some people with ankylosing spondylitis will be encouraged to participate in more swimming sports. Climbing is a good aerobic exercise, but it is easy to go up the mountain and difficult to go down, and people are most likely to suffer knee injuries when going down the mountain. Many of the older population tends to have osteoporosis, the basis of osteoporosis is very easy to induce the occurrence of knee osteoarthritis.
Second, the temperature change is small. Swimming environment has a relatively constant temperature, constant temperature can reduce the occurrence of cardiovascular disease risk. Most middle-aged and elderly people tend to have vascular disease, such as cardiovascular sclerosis or different degrees of narrowing. Climbing a mountain can experience large changes in temperature, especially when climbing relatively high mountains. Due to the large temperature difference between the morning and evening, the temperature difference between the bottom and the top of the mountain is large, and the oxygen content of the surrounding environment gradually decreases in the process of climbing. Therefore, if you don't pay attention to replenishing water and adding or subtracting clothing appropriately when climbing mountains, it is easy to induce the occurrence of cardiovascular and cerebrovascular diseases, such as cerebral infarction and myocardial infarction, in the case of changes in the surrounding temperature.
Third, increase the degree of motor coordination. Because swimming is the need for limbs, spinal joints and respiratory *** with the coordination of the movement. Therefore, swimming can well mobilize the joints and muscles of the whole body, not only fully exercise the muscles and joints, but also enhance the coordination of the body.
Fourth, better increase lung capacity. As swimming reduces the burden on the weight-bearing joints, but the body's joints, muscle movement has not been reduced, but also requires the body to ingest more oxygen to maintain the movement, so swimming to promote their own lung capacity gradually improved. Greater lung capacity, but also help middle-aged and elderly people to enhance the defense ability of respiratory diseases.
