Heart Rate Training Maximizes
Performance
During exercise, the heart beat, or pulse rate, is a valuable
gauge of intensity level - the more vigorous the workout, the
faster the heart must pump to deliver oxygen rich blood to
hard working muscles. Research shows that exercising in
target heart rate zones is the best way to improve
cardiovascular health while preventing under-training which
minimizes results, as well as over-training and risking injury
or burnout. Essentially, it amounts to smarter, more effective
workouts.
Cardiovascular exercise should be performed at 55% to 90%
of oneʼs maximum heart rate (MHR), one way to determine
your MHR is by using the following equation: 220-age=MHR.
Or by using a chart:
Technology boost heart rate monitoring
Heart rate can be measured by palpating an artey and
counting the beats. But even simpler is using a heart monitor,
which consists of a strap worn around the chest that picks
up the heartʼs electric signal and a wristband receiver that
displays the number of beats. Quality monitors are nearly as
accurate as clinical EKGʼs.
The first heart rate monitor was developed in 1977 as a
training tool for the Finnish National Cross Country Ski Team.
During the 1980s, heart rate monitoring became more popular
with athletes, as they saw its effectiveness in enhancing their
performance. Endurance athletes like elite runners,
competitive cyclists, and even Olympic athletes have attested
to better overall results due to heart rate training.
HEART RATE TRAINING
Advances in fitness equipment
Premium cardiovascular machines feature technology that
facilitates accurate heart rate monitoring using telemetry or
hand sensors. With telemetry, exercisers wear a chest strap,
and the machine wirelessly picks up the heartʼs signal and
displays the heart rate on the console. Some manufacturers
also offer hand sensors that exercisers grip to get a heart rate
reading. Because muscle contraction interference can cause
erratic readings with hand sensors, telemetry is generally
more accurate.
Some fitness equipment also offers pre-designed programs
that take the guesswork out of heart rate training by keeping
exercisers at predetermined heart rate zones. For example, in
a workout that requires 80% MHR, the machine picks up the
heart rate from the exerciserʼs chest strap and automatically
varies resistance levels so the user maintains the proper
intensity.
The advantage is that exercisers donʼt have to continually
monitor and readjust to ensure that they are at the appropriate
level because the machine does it for them. These programs
also provide valuable variety, enhance motivation and help
improve performance.
