Not a fan of
gymming? Then, you may be happy to know that scientists may be one step closer
to developing a pill that delivers the same health benefits as a work out.
Everyone knows that exercise improves health, and research continues to uncover
increasingly detailed information on its benefits for metabolism, circulation,
and improved functioning of organs such as the heart, brain, and liver. With
this knowledge in hand, scientists may be better equipped to develop ‘exercise
pills’ that could mimic at least some of the beneficial effects of physical
exercise on the body, but a review of current development efforts ponders
whether such pills will achieve their potential therapeutic impact, at least in
the near future.
Researchers have
recognized the need for exercise pills for some time and this is an achievable
goal based on their improved understanding of the molecular targets of physical
exercise, says coauthor Ismail Laher of the University of British Columbia in
Vancouver. Several laboratories are developing exercise pills, which at this
early stage are being tested in animals to primarily target skeletal muscle
performance and improve strength and energy use–essentially producing stronger
and faster muscles.
But of course the
benefits of exercise are far greater than its effects on only muscles.
Clearly people derive many other
rewarding experiences from exercise, such as increased cognitive function, bone
strength, and improved cardiovascular function, adding that it is unrealistic
to expect that exercise pills will fully be able to substitute for physical
exercise at least not in the immediate future. While exercise pills may provide
some benefits for people in the general population, they might be especially
helpful for those who are unable to exercise for a variety of reasons.
