If you’ve ever taken a Yoga class, then you know firsthand how incredible and instant the benefits are and how energized and flexible you feel afterwards.
Many people turn to Yoga as a form of therapy to reduce stress, induce calm and alleviate aches and pains, particularly in the back.
If there was any doubt of these benefits, a recent study published by the Archives of Internal Medicine, one of the largest US randomized controlled trials to date, has proven that practicing Yoga leads to improved back function and reduced back pain. However, the researchers argue that an intense stretching class will deliver the same benefits when it comes to managing back pain.
“We found yoga classes more effective than a self-care book — but no more effective than stretching classes,” said study leader Karen J. Sherman, PhD, MPH, a senior investigator at Group Health Research Institute. Back-related function was better and symptoms were diminished with yoga at 12 weeks; and clinically important benefits, including less use of pain medications, lasted at least six months for both yoga and stretching, with thorough follow-up of more than nine in 10 participants.
In total, 228 adults who were moderately active and of good mental health were randomly picked to participate in 12 weekly 75-minute Yoga or stretching classes or given a self-care book called The Back Pain Helpbook. Nine in 10 of subjects were primary-care patients at Group Health Cooperative.
In addition to attending the exercise classes, participants were given an exercise video and encouraged to practice at home for 20 minutes a day between their weekly classes. The results were recorded at three intervals: six weeks, 12 weeks and six months.
This research follows on the heels of a smaller study in 2005 that proved that Yoga is effective in alleviating chronic low back pain.
“In our new trial,” Sherman said, “we wanted both to confirm those results in a larger group and to see how yoga compared to a different form of exercise of comparable physical exertion: stretching.
Both the yoga and stretching classes emphasized the torso and legs:
- The type of yoga used in the trial, called viniyoga, adapts the principles of yoga for each individual and physical condition, with modifications for people with physical limitations. The yoga classes also used breathing exercises, with a deep relaxation at the end.
- The stretching classes used 15 different stretching exercises, including stretches of the hamstrings and hip flexors and rotators. Each was held for a minute and repeated once, for a total of 52 minutes of stretching. Strengthening exercises were also included.
“We expected back pain to ease more with yoga than with stretching, so our findings surprised us,” Dr. Sherman said. “The most straightforward interpretation of our findings would be that yoga’s benefits on back function and symptoms were largely physical, due to the stretching and strengthening of muscles.”
But the stretching classes included a lot more stretching than in most such classes, with each stretch held for a relatively long time.
“People may have actually begun to relax more in the stretching classes than they would in a typical exercise class,” she added. “In retrospect, we realized that these stretching classes were a bit more like yoga than a more typical exercise program would be.”
So the trial might have compared rather similar programs with each other.
“Our results suggest that both yoga and stretching can be good, safe options for people who are willing to try physical activity to relieve their moderate low back pain,” Dr. Sherman concluded. “But it’s important for the classes to be therapeutically oriented, geared for beginners, and taught by instructors who can modify postures for participants’ individual physical limitations.”
The bottom line is everybody needs to stretch to increase flexibility and avoid injury. Dedicating at least two sessions a week to either a Yoga or deep stretching session is recommended for optimum health.
