Make no bones about it, TheraPilates for Osteoporosis was a huge success!

I was recently at a conference where Sherri Betz was one of the members of a panel discussion on special populations.  The first question that was asked by the moderator was “What reputable research resources could each of the participants recommend?” Without hesitation, one of the panelist grabbed the microphone and said “Two words, Sherri Betz!”

Osteoporosis Course Tucson

Dr. Tim Lohman, bone health researcher at University of Arizona and Terri Guido, PT from the BEST Study.

Thank you for your participation in this wonderful, dynamic and enriching weekend! From leading researchers in bone health at the University of Arizona, to physical therapists, Pilates enthusiasts, Pilates instructors and athletic trainers, it was a pleasure connecting with such a diverse group of individuals from around the world!

We immediately began to incorporate much of what we learned from Sherri into our sessions at BodyQuest Pilates. It is powerful to imagine the ripple effect that our group of 32 participants can have as we return to our own communities with the ability to apply current research in teaching effective exercise for bone health and avoid high fracture risk exercise for the osteoporotic patients or clients.  Sherri, your work is empowering and inspiring, thank you!  I would also like to say “Thank You” to Michele Franzella, PMA®CPT, who assisted Sherri throughout the weekend.

To Vibrate or Not to Vibrate?

Recently, an interesting randomized placebo controlled “Vibration to Improve Bone in Elderly Subjects” (“VIBES”) trial conducted by some of my favorite researchers (Mary Bouxsein and Clint Rubin) revealed that 2 years of vibration platforms as compared to placebo controls did NOT result in bone density increases in the vertebral bodies or femoral neck nor bone marker improvements in subjects of average age 82.

174 men and women (89 active, 85 controls) were exposed to either 10 minutes of Whole Body Vibration (WBV) on a standing platform or a placebo platform daily for 2 years.  At the 2-year follow-up, biochemical bone markers and bone density as tested by QCT did not improve.

The results do not surprise me.  I have never been a fan of vibration platforms for older adults…they are too expensive and can’t really be practically used for the masses especially if 1 in every 2 people over age 50 have low BMD.  If they were effective for improving bone density in older adults and a vibration “floor” could be designed to vibrate 50 people at a time in a group class, I am all for it!  Sounds like my gut feeling was right all along. We need to stop depending on devices and keep moving our own bodies against gravity!

New Article from Sinaki Nov 2012

Exercise for patients with osteoporosis: management of vertebral compression fractures and trunk strengthening for fall prevention.Jan-Prone Extension2

Sinaki emphasizes the need for stimulation of bone within bone’s biomechanical competence.  She reiterates that compression of vertebral bodies can be insidious and that the absence pain is not a good indicator that fracture has not occurred.  Exercise is an important part of management of osteoporosis and is associated with improved quality of life and decreased risk of fracture.  Exercise programs need to address flexibility, muscle strength, core stability, cardiovascular fitness, and gait steadiness and should be individualized and interesting to the patient/client!  She recommends axial strength and stability, and spinal extensor strengthening progressed with resistance.  A good exercise program should also include balance and lower extremity strengthening.  She also states that oral Vitamin D and Calcium supplements can enhance the effect of strength exercises.

Overall, Sinaki states, a good exercise program should aim to:

  • improve back extensor strength
  • increase level of physical activity
  • improve locomotion
  • reduce back pain
  • reduce fear
  • reduce risk of falls

Bikes and Bones

How-Transition-Clipless-Pedals-Road-CyclingInspired by the AmGen Tour of California, coming through Santa Cruz, I am thinking about the bone density of the world’s top cyclists.  In the past 5 years, much has changed in the way we think about exercise and bone density.  We used to think that weight-bearing or weight training exercise was the best for building bone.  So, just what exercise is best for building bone?  And, what can avid cyclists do to preserve their bones?

We understand that bones need unique forces to stimulate osteoblasts to make new bone.  Exercises that involve repetitive activity, such as swimming, paddling, running, and cycling, work well at first, but their effects are diminished over time and eventually can lead to bone loss.  Swimming actually decreases bone density and a study of water polo players showed that over the season, the players lost bone density in their legs and gained bone density in their arms! (Kavouras, 2006)  Swimming simulates a low gravity environment like being in space.  Astronauts lose bone density at an alarming rate while in space.  Many drugs were originally developed for astronauts to prevent bone loss.  Obviously, the space program has a lot of money to devote to this type of research.  Cycling is a close second to swimming in the bone density race.  It is only a little better than swimming and much worse than running in building bone.  (Rector, 2008) Cycling is non-impact and repetitive and the more cycling the less responsive the bone.   Competitive cyclists generally don’t do any weight training to be as light as possible. Cyclists stay in rounded spinal positions for long periods of time which can be detrimental for putting the spinal vertebrae at risk for fractures in those with low bone density.   Ever seen the cyclist’s humpback?

Another aspect to consider with repetitive high-intensity exercise is the fact that muscles need calcium for contractions and when the calcium stores run out in the bloodstream, where do the muscles get their calcium? From the bones!  Bones are the storehouse for the body’s minerals: calcium, magnesium, boron, manganese, zinc, potassium, copper, etc.  Vitamin D is also very important for absorption of calcium.  For some mysterious reason, studies have shown that worldwide, people are low in vitamin D levels.  If you cycle many miles per week, replace your calcium with at least 1500 mg per day and take 1000 IU’s of Vitamin D (this RDA recommendation has increased from 400 IU’s).

Let’s put the best exercises for building bone in order: gymnastics, volleyball, soccer, high-impact aerobics, tennis, strength training, running, cycling and swimming….you get the idea.

If you are an avid cyclist and care about preserving your bones, it is a good idea to include strength or jumping training for the hips. (squats, lunges, vertical jumps off an 8” step)  Add some back extension exercises for strengthening the bones of the spine.  You might question, “back extension exercises”?  Sinaki, a scientist from the Mayo Clinic has been doing research for about 25 years on exercise and bone, and has found that spinal extension exercises performed in the prone position to strengthen the back muscles are the best for building bone in the spine.  (Sinaki, 2007) Think of the Roman Chair in the gym…

If you are going to start strength training….How many repetitions? How much resistance?  How often?

Repetitions:  A set of 10 repetitions should be very difficult to complete if you are training at the right weight and training for strength.   If you can complete 20 repetitions, the weight is too light and won’t build strength or stimulate bone.

Resistance:  For lunges, squats and back extensions use the heaviest weight that you can lift 8-10 times.

Frequency:  Anywhere from 1-3 times per week sessions of weight training or high impact exercise has been shown to stimulate bone.

Dynamic High Impact Exercise:  Adding some weight-bearing dynamic high impact activities would be a good idea for cyclists to incorporate in their training programs.  Since cycling does not include impact, I think that this type of exercise is imperative for the devoted cyclist in preservation of bone density.   FYI: Walking does NOT build bone!

Whatever you do, don’t quit cycling, especially if it makes your heart sing!  One study showed that the bone density of exercisers as compared to non-exercisers can be exactly the same, but the quality of the non-exercisers bone is different.  The bones of exercisers are stronger and less prone to fracture!  (Tolomio, 2008)    Bone quality is very difficult to measure, is very expensive to measure and puts one in the vicinity of high doses of radiation.

So keep cycling, add a little impact exercise, take extra calcium and Vitamin D and enjoy life!

Effect of office-based brief high-impact exercise on bone mineral density in healthy premenopausal women

Although there is ample evidence supporting the effectiveness of physical activity in the prevention and treatment of osteoporosis, there are no previous studies to examine the effect of office-based brief high-impact exercise (HIE) on bone mineral density (BMD) in healthy premenopausal women. This study evaluated the effects of office-based HIE on BMD in healthy premenopausal Japanese women. Ninety-one healthy premenopausal women were randomized to receive stretching exercise (SE) or HIE (stretching, along with up to 5 x 10 vertical and versatile jumps) for 12 months.

There was a significant difference in the change in the femoral neck BMD between the groups in favor of the HIE group [0.6% (95% CI: -0.4, 1.7) vs. -1.0% (95% CI: -2.2, 0.2)].

These finding suggested that office-based brief HIE can be recommended for premenopausal women for preventing bone mineral loss.
