　　The fitness movement that began in the late 1960s and early 1970s centered around aerobic exercise (有氧操). Millions of people take part in a variety of aerobic activities and gradually thousands of health spasm developed around the country to gain interest in fitness particularly aerobic dancing for females. A number of fitness spasm existed before this aerobic fitness movement, even a national chain with spasm in most major cities. However, their focus (焦點) was not on aerobics but rather on weight-training programs designed to develop muscular mass (肌體) strength and endurance (耐力) in their primarily male enthusiasts. These fitness spasm did not seem to benefit (利益，有益于) financially from the aerobic fitness movement to better health since medical opinion suggested that weight-training programs offered few if any health benefits. In recent years however weight training has again become increasingly popular for males and for females. Many current programs focus not only on developing muscular strength and endurance but on aerobic fitness as well.

　　Historically most physical-fitness tests have usually included measures of muscular strength and endurance not for health-related reasons but primarily because such fitness parts have been related to performance in athletics. However, in recent years facts have shown that training programs designed primarily to improve muscular strength and endurance might also offer some health benefits as well. The American College of Sports Medicine now recommends that weight-training be part of a total fitness program for healthy Americans. Increased participation in such training is one of the specific physical activity and fitness objectives of Healthy People 2000 National Health Promotion. (促進)
