Can't Talk During Exercise?
Slow Down
If you can talk while exercising, you
are likely doing it right, new research indicates.
U.S. investigators found that when
exercisers on a treadmill or stationary bike say they can speak
comfortably, their heart rates and other measures of exertion
tend to fall within the range considered safe for exercisers.
This suggests that people who need
cues for when exercise is too intense don't need to workout with
a heart rate monitor or other complicated device -- they just
need to try the "talk test," the authors say.
"The talk test is a practical way
for people to monitor their intensity during exercise," study
author Dr. Carl Foster said in a statement.
"Because this study has shown this
method to be very consistent, people can use this in their everyday
lives, in gyms or working out at home, to meet their health and
fitness goals while reducing the risk of injuries or other complications
that can happen with overexertion," he added.
Experts have found that people
achieve the most benefits from exercise when their heart rates
and oxygen consumption are kept below maximum values. Given that
many people can't measure their heart rates and use of oxygen
while exercising, members of the exercise community have begun
to adopt the "talk test" to monitor the intensity of their workouts.
An informal measurement, the talk
test states that if people can "just respond to conversation,"
they are likely exercising "just about right," the authors write
in the journal Medicine & Science in Sports & Exercise.
To investigate whether the talk
test does, in fact, measure whether someone is exercising at appropriate
levels, Foster and his colleagues at the University of Wisconsin-La
Crosse measured heart rates and peak oxygen consumption of 16
healthy volunteers as they exercised on stationary bikes and treadmills.
Participants recited the pledge
of allegiance during four progressively harder exercise tests.
The team found that when people
began to struggle with speaking, their heart rates and peak oxygen
consumption began to exceed the threshold for safe exercise.
