Potent Combo for Osteoporosis and Fall Prevention:

In order to keep your bone mass as you age, you have to put adequate stress on your skeletal system, which means some type of resistance training.

Resistance (strength) training can build and maintain lean muscle tissue, as well as maintain your mobility as you age.  This also helps with fall prevention, especially if you build strength in a standing position.

Whole body vibration platforms have been shown to be a legitimate method for building or maintaining bone density in post-menopausal women.  In one study, two groups of women did conventional strength training or vibration training to determine the effects.

The group using vibration training increased their bone density 1.5% at the hip and maintained their bone mass at the spine in a 24 week period.  The conventional training group had no significant increase. 

Oftentimes, we see those 50 and older exercising on weight machines that have them sitting or lying down.  For fall prevention, this doesn't have as much carryover as exercises done in a standing position.  Exercises done in a standing position require multiple joints and muscles to work together, increasing coordination.

In my opinion, this also provides greater stress to the bones, which can help prevent osteoporosis or osteopenia.  Exercises on a whole body vibration platform can include single and double leg exercises to challenge balance and build coordination.  They create a hyper-gravity state, where the force of gravity going through your body is increased.

This is typically done in a static (still) position and then you can add in squats and stepup exercises on the ground to build dynamic strength.  This combination offers the best of both worlds.




A third component could include stepping exercise done on the X-iser.  This involves burst training which simulates sprinting, without the impact.  Besides putting positive stress on the bones, this type of exercise increases balance and naturally increases levels of growth hormone, which decreases with age.

Muscle power decreases with aging and needs to be trained.  How fast your muscles contract (react) can be the difference between falling and maintaining your balance.  You also need some specific exercises to keep the density in your upper back.
