HIIT IT!
A University of Sterling
study showed that doing
fewer intervals during high-
intensity interval training may
produce better cardiovascular
results than pounding out
cripplingly intense intervals.
Researchers found that for
subjects doing two sprints to
the max on exercise bikes, any
subsequent sprints done on
the bike dropped the overall
improvement in fitness—as
measured by VO 2 max, or the
maximum amount of oxygen the
body can use in a minute—by
about 5%.5
JUST ONCE...OR TWICE
THE BEST INTERVAL
Researchers at the University of
British Columbia put three groups—
nonexercisers, regular exercisers, and
people with diabetes—through sessions
of both interval resistance training and
interval cardio. The finding: Interval
weight training improved blood vessel
function more than interval cardio.PERCENTAGE THAT A
RECENT STUDY FROM
THE U.C. SAN DIEGO
SCHOOL OF MEDICINE
FOUND A SINGLE
20-MINUTE SESSION OF
EXERCISE CAN BOOST
THE IMMUNE SYSTEM.GET FIT FAST
Exercise scientists at McMaster
University in Canada put the stairs to the
test to find out how much work you need
to put into climbing them to get a good
health benefit. They had subjects either
go all out on a StairMaster or on the
stationary bike for three sessions of
20 seconds each and, for the second
phase, attack either one or two flights
of stairs in the same manner but for
three 60-second periods. Both protocols
increased peak oxygen uptake: by 12%
in the first phase and 7% in the second.YES, IT’S GOOD FOR YOU
University of British Columbia research
found that just one session of interval
weight training can improve blood vessel
function in those with type-2 diabetes
significantly. All subjects showed
improvement, but the type-2 diabetes
group saw an average of a 2.4%
increase in blood flow.
