YOGA HELPS ASTHMA PATIENTS IN 10 WEEKS
Study shows greater quality
of life, decreases symptoms
SEATTLE – Adults with asthma reported increased
quality of life and reduced asthma symptoms after 10 weeks of yoga
practice, according to research presented today at the
56th Annual Meeting of
the American College of
Sports Medicine (ACSM) in Seattle. The study
followed 20 subjects age 20-65 who were beginners at
yoga.
Subjects received
one-hour yoga classes twice per week and were asked to practice an
additional half-hour weekly at home, for a total of 2.5 hours per week.
After initial warm-ups, deep breathing and stretching, the participants
practiced yoga positions, or asanas. The goal was to hold poses during
deep breathing. According to lead researcher Amy Bidwell, M.S., this
replicates the stress of an oncoming asthma attack. Most previous
research measured the acute effects of yoga on asthma—for example,
after a single, two-hour session. This study, said Bidwell, looked at
the effect of a 10-week training program.
Study
participants completed St. George’s Respiratory Questionnaire before and after the
10-week regimen to assess impacts on their overall health, daily life
and perceived well-being. The results were impressive:
participants’ scores on the questionnaire improved by an average
of 42.5 percent.
For Bidwell, who began
practicing yoga years ago as an alternative to back surgery and now is a
certified instructor, the results were dramatic but not
surprising.
“I have
a number of friends with asthma,” she said. “Many have side
effects from taking medications such as corticosteroids. The
main question was whether or not we could reduce their need for
medication and improve their quality of life.”
Bidwell worked closely
with a physician to design and conduct the study. He had been teaching
breathing techniques to his patients. Based on the study results, he now
is prescribing yoga practice as well.
Further research, said
Bidwell, might include a larger sample size over a longer term. A
12-month study, for example, could incorporate the effect of changing
seasons on participants’ symptoms. Bidwell said the current study
supports the validity of yoga as a therapeutic tool.
“Modern
medicine carries many side effects,” she said. “This is
especially true with corticosteroids, which many asthmatics take for quick relief. Yoga
is an excellent alterative because there are no side effects. It’s
a natural, holistic discipline that can benefit a person’s body in
many ways.”
