運動與慢性病
有證據顯示定期鍛煉可以幫助治療或預防一些慢性病。如定期鍛煉可以幫助控製Ⅱ型糖尿病。鍛煉有可能提高細胞對胰島素的敏感度，於是血糖更容易被吸收和消耗。
一些報告把不愛運動與易患癌症(特別是直腸癌)連接起來。這些結論使人很感興趣。但要肯定地指出好坐的習慣是否是獨立的致癌因素，還需要進行更多的研究。
(3)Swimming
遊泳
Swimming is an excellent cardiovascular exercise that works your quadriceps1，hamstrings2，arms，gluteus3 muscles and abdomens.It's excellent for building stamina4 and muscle tone.Best of all，there's no jarring or shock to the body，which significantly reducesthe risk of injury.
People with injuries or chronic pain，pregnant women and the elderly find swimming a spot that goes easy on the body while offering an efficient workout.Water workouts are sometimes used in post-injury physical therapy，because the water takes some of the body's weight off the joints and tendons5.Because the air around pools is so humid，swimming is often the sport of choice for people with asthma6.
Any aerobic7 exercise will help you get in shape for swimming.Walking and biking are good options for everyone，especially beginners，because they're relatively inexpensive.Running，hiking or indoor cycling classes are other terrific options.
