Can 12 minutes of yoga a day reverse osteoporotic bone loss? The title of this study "Twelve-Minute Daily Yoga Regimen Reverses Osteoporotic Bone Loss" might lead you to believe so, but the results and data are incomplete and inconclusive.  Jules Mitchell and I talk about this complicated, underwhelming study published in the Geriatric Rehabilitation Journal in 2015.

How often do your students ask for help with tight hamstrings? In this episode Jenn Pilotti and I discuss a study that compared 4 stretching techniques for greater hamstring flexibility. This study from the Journal of Strength and Conditioning Research compared two active stretches and two passive stretches in 100 people over the course of 8 weeks. It’s clear that one resulted in the greatest gains. We discuss the results here and in our Yoga Research and Beyond review.

How can Buteyko breathing help with asthma? Research shows 6-30% of asthma sufferers use breathing methods to alleviate their asthma symptoms in the UK.  Catherine and I discuss a paper from the Complementary Therapies in Medicine journal about Buteyko breathing and asthma. Buteyko breathing technique (BBT) is a method that is used in some practices to help with hyperventilation, and asthma. BBT trains people to slow their breath rate, eliminate mouth breathing (using a small strip of tape on the mouth), and use controlled breath pauses to increase CO2 levels. Russian physiologist, Konstantin Buteyko, created it in the 1950’s after experimenting with a slower breathing rate on himself and his patients. He postulated that hyperventilation and mouth breathing create hypocapnia (low CO2), which causes hundreds of ailments, including bronchospasm.

What are Ground Reaction Forces (GRFs) and why are they important? In biomechanics GRF is the force exerted from the ground onto the body when they make contact. It's basically Newton's 3rd law: for every action there is a reaction. Measuring these forces helps us understand how yoga poses impact bones and possibly bone mass.

Can virtual reality technology affect pain perception? Well, yeah. Catherine Cowey and I discuss a fun study about this co-authored by Lorimer Moseley in 2015 in the Psychological Science Journal. The researchers used VR technology to give subjects (with a history of neck pain) the illusion that they had moved their neck more or less than they actually had. As they hypothesized, this had an effect on their perception of pain.

Proximal hamstring tendinopathy (PHT) is a pathology of the tendon with a combination of tissue damage, inflammation, and possibly pain at the proximal tendon where the hamstring attaches to the ischial tuberosity. PHT is very common among yoga practitioners as well as in other populations.  Jules Mitchell and I talk about our own experiences with hamstring injuries as well as a 2016 clinical commentary entitled Proximal Hamstring Tendinopathy: Clinical Aspects of Assessment and Management from the Journal of Orthopaedic & Sports Physical Therapy.
