Weight-bearing regimen and calcium citrate proven to increase bone mineral density
Osteoporosis International, the leading clinical publication on the disease, published data from the Bone Estrogen Strength Training (BEST) Study at The University of Arizona which confirmed that a specific regimen of weight-bearing and resistance exercises, combined with calcium citrate supplement over four years, provided significant improvement in bone mineral density (BMD) of postmenopausal women at key skeletal sites, whether or not they were on hormone therapy (HT).
The findings from this four-year study indicate that the protective measures of adequate calcium supplementation and resistance exercise improve bone mineral density. Women can lose 10 to 20 percent of their BMD as they age, (80% of those affected by osteoporosis are women), but the researchers found that on average women following the exercise and calcium regimen not only did not lose bone density, but increased it by 1 to 2 percent.
Study participants did two sets of six-to-eight repetitions, three times a week. Seven–to-ten minutes of cardiovascular weight-bearing activity, such as stair climbing, treadmill walking with a weighted vest and postural stretches, round out the study regimen. Participants lifted increasingly heavier weights, with the amount of weight lifted in correct form emphasized over number of repetitions.
Building BMD is important in preventing osteoporosis, which often results in fractures of the hip, spine and wrist. Adequate calcium intake and exercise throughout life help prevent bone loss, and these measures also can help the millions of Americans already diagnosed. The best treatment is prevention, and women of all ages should be concerned about their bone health and take action to stay active and improve their nutrition and bone strength.

Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.
So-called monolayers are at the heart of the research activities. These "super materials" (as the prestigious science magazine "Nature" puts it) have been...
Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...
