Regular weight-bearing exercise helps build up bone mass in young
people and helps maintain your bone strength during adulthood.
The great thing is, it is never too late to start exercising, and with the right
program your bones will thank you!
For those who already exercise, it is important that your program includes exercises that are important for bone health. It is very easy to adjust your program to include ‘osteogenic’ (or bonebuilding) exercises:
Here are some pointers:
• People with medical conditions or those who have not been exercising
regularly should consult a doctor before starting any exercise program.
• Weight-bearing exercises that are moderate to high impact and
weight training are the key osteogenic exercises. Therefore,
activities that involve lifting weights, running, sprinting, jumping
and skipping are ideal. In contrast, low impact activities, like
swimming and cycling, are beneficial for cardiovascular health and
weight control but will not promote bone formation.
Good bone building activities include:
• strength training or resistance-training programs
• jogging/running
• jumping
• dancing
• tennis
• volleyball
• brisk or power walking
• Ease into your new exercise program slowly, and progress
gradually with supervision from a qualified exercise specialist.
• Physical activities that are short in duration but high in intensity
will tend to build bone most efficiently (i.e., short sprints rather
than a long, slow jog).
• Two short exercise sessions separated by eight hours are better
than one long one.
• For bone health, if exercise time needs to be reduced, it is better
to reduce the length of each session rather than the number of
sessions per week.
• In older adults and the elderly exercise that improves posture and
balance will help prevent falls and reduce the likelihood of suffering a
bone fracture. The best approach here is to improve muscle strength and
undertake specific balance and co-ordination exercises.
• Maintain a balanced, healthy diet and lifestyle. Ensure your
calcium and vitamin D intake is sufficient, as both are required for
building and maintaining bone mass. Avoid smoking and excessive
alcohol intake as this can contribute to bone loss.
Improving your lifestyle factors (i.e. exercise and diet) alone cannot prevent
osteoporosis; for some individuals medications may be required to
keep bone loss in check.
When considering bone health, it is actually possible to exercise
too much, so your program should be tailored to suit your
individual needs.

Consider these important facts:
• Women and teenage girls who exercise to an extreme degree can
develop amenorrhea (cessation of menstruation) due to oestrogen
deficiency. Oestrogen deficiency in younger women contributes to
bone loss, in much the same way that oestrogen deficiency after
menopause does.
• Preoccupation with excessive exercise may go hand in hand with
eating disorders, such as anorexia or bulimia. The loss of essential
nutrients associated with these disorders has a harmful effect on
bone, and in anorexics, extreme body thinness often results in
• Both male and female athletes who undertake excessive exercise without
adequate caloric intake are at heightened risk of osteoporosis. Athletes
who train hard while trying to keep their weight below a certain level for
competitive reasons are at particularly high risk.
• Excessive exercise can result in stress fractures or joint damage.
• The elderly and those who already have osteoporosis can put
themselves at risk of fracturing if they suddenly begin a strenuous
that might increase the likelihood of falling.

Happy Healthy Body Training
