title: Yoga, as a transitional platform to more active lifestyle: a 6-month pilot study in the USA.
abstract: A 6-month pilot study explored the effects of a yoga program on the physical activity (PA) level of overweight or obese sedentary adults. Fourteen community-dwelling overweight or obese sedentary adults participated in a 6-month program (2-month yoga program and 4-month follow-up) delivered by two types of instruction [the direct guidance of an instructor (face-to-face group) vs. the self-learning method of using a DVD (DVD group)]. Measurements included program adherence (class attendance and home practice; min/week) and level of PA [metabolic equivalent (MET)-hour/week] at baseline, 2, 4 and 6 months. Descriptive statistics and nonparametric tests were used to describe the sample and examine differences by group and time. There were no significant differences in demographic variables by group assigned. Participants showed significant PA changes from baseline to each measurement point. The direct guidance of an instructor was preferred over the self-learning method. At each time interval, the DVD group showed higher levels of PA than the face-to-face group; the only difference that achieved statistical significance occurred at 4 months. The PA level significantly changed over 6 months in the DVD group, but not in the face-to-face group. The results indicate that a yoga program may be utilized as a 'stepping-stone' toward regular exercise among overweight sedentary adults. Research with a larger sample is needed to further evaluate the effects of the program on the level of PA among this population.
