Try waltzing to improve heart function

New York: Doing the waltz could improve heart functions and the quality of life among chronic heart failure patients, suggests a study.

Waltz, a ballroom dance done primarily in close position with a partner, helps improve elasticity in the arteries of heart patients and was better than aerobics.

Romualdo Belardinelli and other researchers in Italy studied 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 programme 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, reported health portal Health Central.

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, said the researchers at the American Heart Association's annual meeting, in Chicago, where they presented their findings.

Among the aerobic exercisers, oxygen consumption increased 16 per cent, compared to 18 per cent for the dancers.

Anaerobic threshold, or the point above which muscles start to tire, increased 20 per cent among exercisers and 21 percent among dancers.

Cardiocirculatory fitness increased 18 per cent among the exercisers and 19 per cent among the dancers.

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 programme.

The benefits for people in the dancing group appear at least as great, and sometimes greater, than the benefits gained from more traditional aerobic exercise, they said.
