据每日健康新闻11月12日报道，意大利Lancisi心脏研究所的研究人员发现，跳华尔兹舞可改善慢性心衰患者的心脏功能容量，提高其生活质量，而且没有副作用。与传统的有氧运动相比，这种形式的运动可谓好处多多。这些结果公布于本周日在芝加哥举办的美国心脏病协会（AHA）年会上。

该研究的首席作者Romualdo Belardinelli在会上阐述了做此研究的初衷：“我们发现，有时心脏病患者在运动训练计划中不能很好坚持，因此必须找到能抓住他们兴趣点的运动形式。”

在之前的研究中，他们就已发现慢华尔兹和快华尔兹对心脏病及之前有过心脏病发作的患者来讲，都是健康有效的运动形式。这次研究人员基本上是重复了第一次的研究，受试者中110人患慢性心衰，其中男性89人，平均年龄为59岁。他们被随机选出参与传统有氧运动（骑车，一种三次，连续8周）或参加一个舞蹈项目，后者采取慢华尔兹（5分钟）与快华尔兹（3分钟）交替形式，共21分钟。这些舞蹈同样是一周三次，连续8周。还有一组受试者不做运动，作为对照组。

结果表明，跳华尔兹舞可以改善心脏功能容量，提高患者生活质量，尤其是在情绪方面。不做运动的对照组在这些方面则无任何改善。跳华尔兹舞组的心肺耐力、耗氧量及无氧阈值、生活质量改善指标都略高于传统有氧运动组。 此外，跳舞组患者动脉的弹性也得到改善。而且，跳舞的安全性也有保障。

美国迈阿密大学米勒医学院医学及生理学教授Robert Myerburg补充道：“对于有心脏病的人来讲，这或许是一个适合他们承受水平的锻炼好方法，而且这也是一种享受。另有专家认为，跳舞与传统有氧运动相比，主要区别在于人们通过跳舞心情更加愉悦，且易于坚持。因此，它或许可作为这些患者运动训练的有益结合或者替代形式。

Heart Failure Patients Can Waltz Their Way to Stronger Hearts
11.12.06, 12:00 AM ET

SUNDAY, Nov. 12 (HealthDay News) -- Why walk your way to better heart health when you can waltz?
That's the question posed by Italian researchers who've found that waltzing improves heart function and quality of life among chronic heart failure patients. The benefits appear at least as great, and sometimes greater, than the benefits gained from more traditional aerobic exercise.

"Why not?" said Dr. Louis E. Teichholz, division director of cardiology and chief of complementary medicine at Hackensack University Medical Center, in Hackensack, N.J. "The important thing about exercise is that you have aerobic exercise, and certainly this is good aerobic exercise, especially a waltz, where you're constantly moving."

Added Dr. Robert Myerburg, a professor of medicine and physiology at the University of Miami Miller School of Medicine: "For the person with heart disease, this might be a good way to do exercise to their level of tolerance, and it would be enjoyable for them. You could adjust the form of dance you're doing for the person who is mildly limited because of heart disease."

The Italian researchers presented their findings Sunday at the American Heart Association's annual meeting, in Chicago.

Explaining the rationale for the research, lead study author Dr. Romualdo Belardinelli told a Sunday AHA news conference, "The problem is that sometimes the adherence of cardiac patients to exercise training programs is not very high, so we have to find something that may capture their interest."

"Waltz dancing improves functional capacity and quality of life for chronic heart failure patients without important side effects. It may be considered in combination or as an alternative to exercise training in these patients," added Belardinelli, the director of cardiac rehabilitation and prevention at Lancisi Heart Institute in Ancona, Italy

In a previous study, the same researchers had found that slow and fast waltzes were safe and effective forms of exercise for people who suffered from heart disease and previous heart attacks.

This time, the investigators basically repeated that first study in 110 individuals with chronic heart failure, 89 of them men, with an average age of 59.

The study participants were randomly assigned to do traditional aerobic exercise, including cycling and treadmills, three times a week for eight weeks, or to do a dance program that alternated slow waltzes (five minutes) and fast waltzes (three minutes) for a total of 21 minutes. The dance sessions were also performed three times a week for eight weeks. A third group did not exercise and served as a control group.

Dancing improved both functional capacity of the heart and quality of life, especially in the area of emotions. There was no improvement at all in these areas among patients who did not exercise.

Cardiopulmonary fitness increased at similar rates in the routine aerobic group and in the dance group, with dancers experiencing slightly greater benefits.

Among the aerobic exercisers, oxygen consumption increased 16 percent, compared to 18 percent for the dancers. Anaerobic threshold, or the point above which muscles start to tire, increased 20 percent among exercisers and 21 percent among dancers. And, cardiocirculatory fitness increased 18 percent among the exercisers and 19 percent among the dancers.

People in the dancing group also saw improved elasticity in their arteries.

Finally, quality of life improved more in the dancing group than in the exercise group.

And dancing was safe; no one had to withdraw from the program.

"I don't think you could say this is better than good aerobic exercise," Teichholz said. "The major difference is people were happier doing it. In people with heart failure and in normal people, we need to think that exercise can take various forms, and dancing certainly in this study is shown not to be deleterious and actually to be helpful."
