Why Evidence-Informed Yoga Blogging?

A few months before plunging into my work for this blog, I developed a healthy obsession with yoga-related information. I had submitted my application to start my 200-Hour Yoga Teacher Training (which began in September) and was thirsty for any book, blog, podcast, or journal that would broaden my understanding of yoga, anatomy, biomechanics, mindfulness, and more. I quickly noticed a pattern in the reliability of the yoga-related sources: with the exception of a few complete quacks on one end and some stellar works at the other, the information coming out of yoga-related blogs, books, podcasts, and journals is often: opinion-based; void of research; passed down from a Guru; possibly biased and/or sometimes created with conflicts of interest (see Figure 1*).

In other words, most yoga podcasts or blogs are a mixed bag of some great information and ideas, lots of opinions, and some information that is poorly researched (if at all) and/or cited. With the exception of conflicts of interest, there is nothing wrong with opinions, hands-on experience, and advice from a Guru — if it helps don’t fix it! That being said, I think the audience should be able to decipher between opinions or a Guru’s advice and an evidence-based method. One podcast I listen to, for example, has interviews with both academic researchers as well as quacks with conflicts of interest (that are, of course, never declared). I don’t want to name names because my intention is merely to reveal an opinion of my own: it is difficult to navigate through the information mediums of the yoga-world with confidence that the source is reliable and the information is accurate.

 

Without searching the scientific literature (which is financially, practically, and academically inaccessible to the majority of the population), it is difficult to gain access to reliable sources and accurate information. Further, I believe the scientific literature would provide tremendously helpful input to the field of yoga. It’s a position that is too often ignored in the yoga world and I have created Kerry McInnes Yoga with the intention of adding a new voice to the dialogue.

 

It is no surprise that the field of yoga is lacking in voices that take an evidence-based approach. B.K.S Iyengar, yoga’s darling guru, infamously peppers his books with medical terminology wildly claiming that his asanas, or poses, have the ability to “cure” anything and everything from sterility to polio! Without including a single citation, there is no mention of randomized controlled trials or even a lonely case study. Gurus aside, the growing popularity in the Western world and precious research dollars being allocated its way, yoga is finally beginning to be empirically studied. To date, however, the yoga research is still sorely lacking: for the most part, studies are small, randomized controlled trials are biased1, and who wants to fund yoga research anyway? That said, movement-related research (e.g., kinesiology, sports medicine, biomechanics, rehabilitation science) is not a meagre area of study. By broadening the scope of research to include related fields of study, we can improve the quality of information emerging from the yoga community. Further, I believe an evidence-informed approach to yoga can diminish the shadow looming over the yoga community.

 

Not all fields have this shadow looming over their reputation. Ironically enough, Dr. Loren Fishman was introduced to yoga through B.K.S. Iyengar. He is now an Assistant Professor at the Columbia Medical School and has written extensively on the topic of yoga and rehabilitation. He was interviewed for William J. Broad’s recent book The Science of Yoga2 where he remarks:

 

Yoga is in danger […] It can tip either way — toward science or religion, towards people who are seeking to know the truth or toward people who like hierarchies.’ Most yoga therapists get their information from a guru […] But science now has the means to determine what really works in yoga therapy and why […] Its methods can reduce false diagnoses and risky treatments. Its respect for the facts […] can help turn the fledging discipline into a real profession.

 

To be clear, I don’t believe science has all the answers, as the previous statement might condone. Science is only as powerful as its lowest common methodological denominator — and there are some serious methodological limitations to the scientific method! I just don’t believe that advice from the Guru is the only solution. I think we need to inform our practices with the best evidence we have while recognizing the limitations and continue to search for better answers.

 

On a personal note, I just passed my four-year anniversary with a chronic health condition to which I have received little help from the conventional healthcare system. My husband is in medical school and he is not offended by this statement. In fact, he also holds the opinions that our healthcare system is relatively inept at addressing chronic health conditions. And if you haven’t already put the pieces together, I have left the field of research and academia to pursue a career in a form of complementary and alternative medicine — yoga!

 

In light of the aforementioned limitations concerning both access to and reliability of information relating to yoga, I have created Kerry McInnes Yoga: An Evidence-Informed Approach to Movement. KMY will look at a variety of topics related to yoga with an emphasis on the mind-body connection. Topics will include, but will not be limited to: anatomy, neuroscience, psychology, rehabilitation, and more! When I am writing about my opinions, it will be clear that they are indeed my opinions.

 

Seeing as this is my introductory blog post, I think it is the best place to make a disclaimer: I am going to make mistakes. All future posts will be the result of my best effort to deliver an evidence-based approach to a given topic. Readers should bear in mind, however, that scientific literature almost never has a clear interpretation and there are always conflicting findings. Further, my posts will aim to stay around the thousand-word mark and thus there will be limitations to what I can communicate. Finally, I have no funding and I am only one interpreter of the literature.

 

If you head on over to the About page, you can read a little bit about my background. Before I conclude, I need to share a declaration of interest, perhaps. While I stated earlier that this blog was created with the intention of writing an evidence-informed platform that is accessible, this is merely the secondary intention of my blog. My primary intention is completely egocentric and pedagogical in nature. That is, my primary interest in writing and researching for KMY is to learn and engage with the literature and information I find. In doing so, I hope to become as informed as I can with the information and time that I have. In turn, I believe this journey will help me better serve my (future) students as a yoga teacher and myself as a yogi!

  1. Kerry, Thanks for this first post. I appreciate your transparency in using your blog to learn and engage with the current literature you find (and there is an abundance). I find it interesting – your view on the scientific community – on one hand appreciating the effort and commitment to the method and also the limitations of this. I look forward to ways in which you might unveil both of these in examples that I as a yoga teacher can understand. I agree, your engagement this way will be of benefit to many.

  2. Hi Kerry, Congratulations! Your approach is refreshing – asking the question “why” am I doing this ? Does it make sense in my body? Wheres the evidence? In a society that seems to have so little time for anything especially something as abstract as learning/studying for the sake of pure knowledge – we have become blind followers – robotic almost- so the mind/body benefit is lost and injury is all too common. So looking forward to how your inquisitive mind will take on future topics:) I also LOVE your logo and the description – the “elegance of the spinal cord” – so incredibly true:) and of course I think you are beyond brave challenging Master Iyengar!!
    Namaste my friend

    1. Thanks for your comment, Angela! As I have been navigating the world of yoga-related information, I have too often found myself dissatisfied with the quality of information. That being said, there are also a lot of fantastic resources out there. It is my intention with this blog to contribute to this information with an approach that I believe will resonate with the many yogis.
