of the tour caliber riders have bones of an 80 year old woman
with osteoporosis. One female world mountain bike champion had
to stop competing at age 32 because of bone thinning. At least
5 La Grange members have known bone thinning. Some of you have
been coming in for Cardiac Screening because of palpitations.
600mg of calcium and 300 mg of magnesium once or twice a day as
a supplement. Caution is needed or you should consult your doctor
first if you have a history of calcium containing kidney stones.
Stand on your pedals. Alternate occasional mountain biking. Do
back exercises and 1 day a week run, hike or go to the gym and
do machines and/or weight training.
A Bone Density Study. You can ask your doctor to order this.
If you have no doctor or if your health plan will not cover it
and you want to pay for it, I can order it for you.
menopausal women break down bone faster than they remodel it by
laying down new bone. Treatment has been calcium and vitamin D
supplementaion. When that fails, a medication that blocks bone
re-absorption is given. In extreme cases, parathyroid hormone
has been given to build new bone. We are on the verge of seeing
a whole series of new medicines released that can build bone density
back to normal or at least stop the progression of bone loss.
Men as you
would guess are a different story. It was noted several years
ago that some of the world class cyclists were developing bone
loss particularly in their spine. It was originally ascribed to
riding properly from the waist down and not putting tension on
the bones of the spine. This is necessary to lay down new bone
and prevent total bone loss.
A sharp journalist
doing a story about this problem suggested that their had to be
more to this and asked whether there was a large loss of calcium
in sweat. No one had ever investigated this. Studies were done
and there is a very large loss of calcium in sweat. To correct
both aspects of the problem, cyclists need once a week to do an
alternative form of exercise that puts stress on the spine and
take supplementary calcium.
stabilizes cell membranes and is particularly anti arrythmogenic.
A number of people have come in for their cardiac screening primarily
because they were experiencing palpitations. Both actually had
extra heart beats. This was during periods of intense heat and
neither were taking calcium and magnesium supplementation. One
went away without treatment probably because diet alone restored
their electrolyte balance. The other was already going away but
did seem to respond to taking supplementary calcium and magnesium.
message is clear. We all need to include supplemental calcium
and I would recommend magnesium in our daily regimen. Riding as
your only form of exercise is not healthy for your bones.
