Sports injuries make it difficult for older persons to exercise

Though vigorous exercises like aerobics and jumping or skipping rope will boost the metabolic rate and use up a lot of calories, there are some risks involved in exercising, especially for middle aged people and senior citizens . If the body is not used to exercising regularly, the person will be more likely to suffer from sports injuries causing torn ligaments, muscles and in some cases fractures.
While young people recover quickly from their sports injuries, it will take a lot of time, for the body of senior citizens and older people to repair itself, so that the person is painfree.
Hence it is advisable to do only stretching and other low impact exercises where the risk of injuries is less
