A 2010 study published in the Clinical Journal of Sports Medicine found that active stretching (where the muscle opposite the one being stretched is contracted, as is often the case in yoga poses) resulted in lasting, improved range of motion, while passive stretching actually decreases range of motion.
As a firmly evidence-based practitioners we cannot help but be pleased by the evidence accruing in yoga’s favour. As well as all the demonstrable benefits for wellbeing, it just feels good.
It seems likely that the researchers will catch up with yoga devotees eventually. By starting the practise younger and continuing until we’re much, much older we can genuinely limit the number of invasive medical interventions we undergo in our lives.
