A Scientist's Perspective on the "Dangers" of Yoga for Men

A Scientist's Perspective on the "Dangers" of Yoga for Men Nina Zolotow by Ram

Happy, Healthy Warrior Pose

William Broad, author of The Science of Yoga, wrote an article in the New York Times Wounded Warrior Pose, which claimed that yoga is “remarkably dangerous” for men. While this article is a must read for folks who practice yoga asanas (practitioners, teachers in training or students), there are several important issues mentioned in the article that needs to be properly understood and clarified.

Let’s start by clarifying for the benefit of practitioners and non-practitioners: the main reference throughout the article is to yoga asanas and not yoga per se. While this seem trivial, it is very important because one can resort to other yoga activities like dharana (focus), dhyana (meditation), pranayama (regulated breathing) and sustain very minimal if no injuries. Also, yoga is not a competitive sport; for more on this kindly refer to BKS Iyengar’s book Light on Yoga.

While it may seem that the practice of yoga asana is largely a feminine pursuit, such gender inequalities exist in several other sports and training programs. We do not see a mainstream women's equivalent of American football, the zumba and pilates classes in the gym that I go to is dominated by females and it is mostly men that are busy working out their “ceps and packs” in the weight lift arena. Uncoordinated or improper movements can put an individual at risk and subsequent injury in any sport or training program. The same is true for yoga asanas, which require coordinated movements of several areas/parts of the body.

William Broad acquired medical data, performed a non-scientific partial analysis and concluded that gender differences in yoga injuries exist and men are at most risk for these types of injuries. To me it seems that the differences could be explained at least in part by differences in the amount of training and asana practice.

Retrospective training/sport injury studies have to be normalized (a suitable denominator has to be factored in). Typically, total exposure time in hours or months or years have to be factored in to draw a reasonable conclusion. In a retrospective 12-month scientific study reported by a group in Finland and published in the 2009 issue of Journal of Sports Science and Medicine, the authors concluded that after combining all reported acute injuries sustained by cross-country skiers, swimmers, long-distance runners and soccer players, no significant difference was observed in such injuries when calculated per 1000 exposure hours.

Similarly, another study comparing sports injuries in men and women that was reported by a group of family practitioners from Kaiser Permanente found no statistically significant gender difference for injuries per 100 participant-years (Sallis et al; Int J Sports Med. 2001 Aug;22(6):420-3. Comparing sports injuries in men and women).

If proper scientific standards were applied to Broad’s yoga analysis, it would mean factoring in the mean exposure hours of yoga asanas performed. Based on the above studies my gut feeling is that no gender differences would similarly be found in injuries sustained from yoga asanas.

So do not be put off by Broad’s article! Remember yoga philosophy, which includes asana practice as well, does not discriminate between estrogen and testosterone. The major component of the practice is about “letting go” of the ego, including your body image, and finding your true self. So focus on yourself and your personal practice. And focus less on a “macho” body and more on achieving stability, mobility and encouraging integration—gently coaxing all the muscles that are tight from sports and weight training to move and work together. Pay close attention to connections—between one part of the body and another, between thought and action and between breath and movement. Moving with this awareness helps in reducing risks from any serious injuries.
