SLEEP WORKS
Q Along with all the other
important benefits of getting a
good night’s sleep—better
memory, enhanced immune
system, improved muscle
recovery—research recently
published in PLOS Medicine
established that physically
inactive people who sit for
most of the day and sleep less
than seven hours a day or
more than nine hours a day
are more than four times as
likely to die early than a per-
son with a healthy lifestyle.
Q Rest assured that just by
picking up this magazine and
following our time- and gym-
tested tips, you are most
likely extending your life. A
new study from Vanderbilt
University Medical Center
found that people in midlife
who have high levels of fitness
go on to have much lower
annual health bills when they
get past age 65. Researchers
studied almost 20,000 people
over 22 years from age 49 to
71 and worked out that the fit
subjects saved about $5,000
in health-care costs each
year once they got into their
golden years.

Forget to do cardio again?
Research out of the Boston
University School of Medicine
may, ahem, jog your memory
the next time you pass the
treadmill. The study tested
adults ages 18 to 35 on their
aerobic capacity on a tread-
mill, then used an MRI to view
areas of the brain that deal
with memory. Those with
higher aerobic fitness had more
gray matter in the memory
banks, supporting previous
data that suggests cardio
can play a role in preventing
cognitive decline as you age.
JUST A SPOONFUL
OF SUGAR
Q Before your next big physical event, like
a Mud Run or CrossFit Benchmark WOD, try
a trick discovered by researchers at the
U. of Bath in England. Their study tested
various carb concoctions on long-distance
cyclists’ endurance and levels of glycogen
(or energy) in the liver and found that
to maximize energy, or carb availability, y
