共用题干 Good Way to Exercise:JoggingJogging has become the most popular individual sport in America. Many theories,even some mystical ones,have been advanced to explain the popularity of jogging. The plain truth is that jogging is a cheap,quick and efficient way to maintain(or achieve)physical fitness.The most useful sort of exercise is exercise that develops the heart,lungs,and circulatory systems.If these systems are fit,the body is ready for almost any sport and for almost any sudden demand made by work or emergencies.One can train more specifically,as by developing strength for weight lifting or the ability to run straight ahead for short distances with great power in football,but running trains your heart and lungs to deliver oxygen more efficiently to all parts of your body.It is worth noting that this sort of exercise is the only kind that can reduce heart disease,the number one cause of death in America.Only one sort of equipment is needed一a good pair of shoes.Physicians advise beginning joggers not to run in a pair of tennis or gym shoes.Many designs have been made in only the last several years that make a pair of excellent running shoes in dispensable if a runner wishes to develop as quickly as possible,with as little chance of injury as possible.A pair of good running shoes will have a soft pad for absorbing shock,as well as a slightly built-up heel that will give the knee and ankle more stability.A wise investment in good shoes will prevent the foot,ankle and knee injuries and will also enable the wearer to run on paved or soft surfaces.No other special equipment is needed and you can jog in any clothing you desire.Many joggers wear expensive,flashy and warm suits,but just as many wear a simple pair of gym shoes and T-shirt.In fact,many people just jog in last year's clothes.In cold weather,several layers of clothing are better than one heavy sweater or coat. If joggers are wearing several layers of clothing,they can add or subtract layers as conditions change.It takes surprisingly little time to develop the ability to run.The American Jogging Association has a twelve-week program designed to move from a fifteen-minute walk(which almost anyone can manage who is in reasonable health)to a thirty-minute run.A measure of common sense,a physical examination.and a planned schedule are all it takes. Jogging is an expensive way to maintain physical fitness.
