Internal (e.g. lack willpower, too lazy, busy) chosen most frequently. logistic regression range variables those selected only internal less likely take more (OR 0.59, 95% CI 0.41, 0.86) than external no transport, can't afford sports facilities) or mixed changing. There similar but not statistically significant trend for 0.78, 0.48, 1.28). are aware limitations may better placed circumvent them. Further research is needed explore relationship between barrier change.
