Mental Health. When asked why she started swimming during her freshman year at Boston
University, world-class endurance swimmer Julie Ridge replied, "It was a mental thing." While
sedentary people may assume that working out is about looking good，habitual exercisers like Ridge know that it is largely about feeling good. A growing body of research shows that physical activity does, indeed, exert a "feel good" effect that can work as a powerful treatment for depression.
Arthritis. Many people -- including some physicians -- still haven t heard the new message
that exercise can help people with arthritis now affecting nearly 43 million Americans. "We ve come from thinking that physical fitness was impossible for people with arthritis to know that
exercise is one of the best ways to manage their disease and minimize their disability," says Marian Minor, an associate professor of Physical therapy at the University of Missouri, Columbia.
Exercise can reduce pain by keeping joints (关节) flexible and the muscles around the joints strong. A person with arthritis who has other medical conditions or a lot of pain should get a
physician s referral (建议) to a physical therapist who can design an individualized exercise
program.
Cancer. Each year over a million Americans learn they have cancer -- the second leading cause of death in the Unites States after heart disease. In 1996 the American Cancer Society added regular physical activity to the list of preventive measures it advocates. According to one large
Bbpprzu大学英语四级新题型考试预测试卷4
study of people at various levels of fitness, the least fit men died from cancer at a rate more than three times higher than that of the most fit men. And, notes Informed Decisions, the American
Cancer Society s guide to the disease, an earlier study found "the least fit women had fully16 times the cancer death rate of the most fit women."
Scientists still don t know the precise mechanisms by which exercise appears to exert an
“anticancer” effect, but current thinking points to physical activity s effect on the immune and endocrine (内分泌的) system.
So Choose to Move. Stop viewing exercise as a "workout" and start thinking of it as play – a welcome daily recess (暂歇) that frees your body from the confines of its workaday routines. And if you have any health concerns, you should, of course, consult a physician first.
