Why Yoga Isn’t Sufficient to Enhance Bone Density

Can yoga really enhance bone density?

In the event you ask Google, you’ll discover all kinds of sources saying sure—yoga is an efficient methodology for constructing bone density and stopping osteoporotic fractures, like hip or femur breaks from falls.

A seek for “Yoga for Osteoporosis” pulls up hundreds of hits for books, applications, and movies promising that can assist you construct higher bones with a low-impact yoga observe. Even Yoga with Adriene has a “Yoga for Bone Well being” video on her channel, which reaches over 12 million subscribers.

However most of these hyperlinks hint again to 1 primary supply: the work of Dr. Loren Fishman, creator of a number of books together with Yoga for Osteoporosis. He’s additionally the co-author of a 2015 examine that implies yoga can enhance bone mineral density (BMD) within the backbone and femoral neck—doubtlessly decreasing the danger of life-threatening fractures in older adults. The examine was titled, “12-Minute Every day Yoga Routine Reverses Osteoporotic Bone Loss.”

The Research That Made Waves within the Yoga World

I keep in mind when the information of Dr. Fishman’s study got here out. It was an enormous deal within the yoga world and despatched ripples by the broader wellness house.

As a substitute of simply being recognized for leisure, yoga may now be seen as a one-stop-shop for all of your health wants.

It was nice information for yoga practitioners—and nice for enterprise, too. Studios and academics now had scientific backing for what they have been already selling. The examine additionally helped convey yoga additional into the mainstream and validated what many longtime yogis already believed about their beloved observe.

However the larger query remained: Are the examine’s findings legit?

What the LIFTMOR Trial Tells Us About Bone Progress

Curiously, the identical yr Dr. Fishman’s examine was printed, so was the LIFTMOR trial.

The LIFTMOR trial additionally studied osteoporosis—particularly in postmenopausal ladies with no vital historical past of train and low bone mineral density. Contributors have been break up into two teams: one did low-impact motion at dwelling, whereas the opposite did supervised high-intensity progressive resistance coaching (HiPRT). Every group exercised twice per week for half-hour over an eight-month interval.

The outcomes? There was a vital distinction in bone development between the low-intensity dwelling group and the supervised energy coaching group. And people outcomes have been replicated in a number of comparable trials that adopted.

Even higher? The resistance coaching group had no accidents reported.

So, if low-impact motion had minimal influence on BMD, however the Fishman examine claimed yoga (additionally low influence) elevated BMD—what provides?

Why Dr. Fishman’s Research Falls Brief

There are a number of flaws in Dr. Fishman’s examine that make the outcomes much less scientifically legitimate.

1. No management group. This implies they’re not evaluating the outcomes of individuals doing yoga to folks not doing yoga. They have been merely doing 12 poses and monitoring their progress—typically qualitatively (“how do you’re feeling?”), typically quantitatively (by way of bone scans). With no management group to match the outcomes to, it’s laborious to attract dependable conclusions from the findings on this examine.

2. The examine hasn’t been independently replicated. It lacks sufficient element for others to breed it and validate the findings.

3. Potential for bias. Dr. Fishman funded the examine himself. That doesn’t robotically disqualify the work, but it surely does increase purple flags—particularly on condition that he earnings from yoga books, applications, and trainings if the findings help the usage of his services and products.

4. It’s not a blind or double blind examine.

Each one who participated was already a yoga practitioner once they began. It wasn’t a brand new observe for them, however acquainted. One thing they most likely loved. This is able to have additionally seemingly impacted how they responded to the yoga poses or have been merely extra inclined to remain dedicated to doing the poses constantly.

Collectively, these components restrict the examine’s validity and scientific rigor.

The Actual Science Behind Constructing Bone Density

Right here’s what we do know: to construct bone, it’s a must to stress bone.

Which means making use of a certain quantity of stress to bones to stimulate development.

And as your physique adapts, you have to enhance that stress over time. That is what progressive overload is all about—growing the burden or impact to maintain your bones responding and getting stronger.

Put merely, yoga doesn’t apply sufficient pressure to considerably enhance bone density.

Let’s Get Sensible: What Yoga Can (and Can’t) Do

Most of the poses in Dr. Fishman’s examine have been standing, however some have been seated. One was supine and inactive—savasana, pose #12.

If seated and supine positions constructed stronger bones, we’d all be growing BMD whereas driving or sleeping.

Within the examine, Dr. Fishman argued that yoga pits opposing muscle teams in opposition to one another in a manner that stimulates bone development. He wrote:

“By pitting one group of muscle tissue in opposition to one other, yoga exposes bones to higher forces and, due to this fact, would possibly improve bone mineral density (BMD) greater than different means.”

Sadly, this merely isn’t true.

At greatest, yoga includes bodyweight-only pressure—about the identical as strolling your canine. And research repeatedly present that bones want vital load or influence to develop: issues like lifting heavy weights or leaping.

So, Can Yoga Assist You Construct Power?

Sure—to a degree. However for most individuals—no.

Yoga is a unbelievable basis for energy, significantly when you’re new to motion, recovering from harm or sickness, or engaged on reconnecting along with your physique.

As a result of it makes use of body weight solely (plus gravity), you’ll finally plateau in how a lot energy you may acquire. But it surely’s nice for constructing endurance when you maintain poses for longer than a number of breaths.

One Observe Can’t Do Every part

Let’s be actual: no single observe checks each health field.

Power coaching builds muscle and bone, but it surely’s not cardio. Biking is nice for cardiovascular well being, but it surely received’t enhance bone density. Dance is enjoyable and expressive and gives influence and cardio, however not energy.

Each sort of motion has its strengths and limitations—and that’s okay.

The purpose is just to say that our our bodies want selection and one fashion of motion can’t do all the pieces our our bodies should be wholesome.
