From: The efficacy of a comprehensive lifestyle modification programme based on yoga in the management of bronchial asthma: a randomized controlled trial

% change in 11β-PGF2α excretion. (All subjects) Yoga (n = 29) 17.6 ± 18.6 19.7 ± 24.7 14.7 ± 16.5 16.8 ± 19.7 0.49
  Control (n = 28) 16.6 ± 21.0 18.6 ± 22.0 16.3 ± 22.3 20.7 ± 23.5 0.84
ES subjects (mean ± SD) Yoga (n = 13) 18.3 ± 22.2 20.4 ± 29.5 13.8 ± 16.8 12.3 ± 16.9 0.63

ER subjects (mean ± SD) Yoga (n = 16) 17.1 ± 15.9 19.0 ± 21.0 15.4 ± 16.8 20.4 ± 21.5 0.79

  1. All values (normalized) are expressed as % change in 11β prostaglandin F2α excretion with exercise challenge (mean ± SD). ES – exercise sensitive; ER – exercise resistant subjects.
  2. a P-value was based on Friedman test in each group separately from % change in 11β-PGF2α with exercise.
  3. *p < .05 based on Mann-Whitney U test at 4 wk between two groups.
