view the performance widget.
2 Select START to scroll through the
performance measurements.
Your projected race times appear for 5K, 10K,
half marathon, and marathon distances.
NOTE: The projections may seem inaccurate at
first. The device requires a few runs to learn
about your running performance.
Performance Condition
As you perform a running activity, the performance
condition feature analyzes your pace, heart rate,
and heart rate variability to make a real-time
assessment of your ability to perform compared to
your average fitness level. It is approximately your
real-time percentage deviation from your baseline
VO2 max. estimate.
Performance condition values range from -20 to
+20. After the first 6 to 20 minutes of your activity,
the device displays your performance condition
score. For example, a score of +5 means that you
are rested, fresh, and capable of a good run. You
can add performance condition as a data field to one
of your
training screens to monitor your ability throughout
the activity.
Performance condition can also be an indicator of
fatigue level, especially at the end of a long
training run.
NOTE: The device requires a few runs with a heart
rate monitor to get an accurate VO2 max. estimate
and learn about your running ability (
About VO2
Max. Estimates, page 18
).
About Training Effect
Training Effect measures the impact of an activity on
your aerobic and anaerobic fitness. Training Effect
accumulates during the activity. As the activity
progresses, the Training Effect value increases, telling
you how the activity has improved your fitness.
Training Effect is determined by your user profile
information, heart rate, duration, and intensity of your
activity.
Aerobic Training Effect uses your heart rate to measure
how the accumulated intensity of an exercise affects your
aerobic fitness and indicates if the workout had a
maintaining or improving effect on your fitness level. Your
EPOC accumulated during exercise is mapped to a range
of values that account for your fitness level and training
habits. Steady workouts at moderate effort or workouts
involving longer intervals (>180 sec) have a positive impact
on your aerobic metabolism and result in an improved
aerobic Training Effect.
Anaerobic Training Effect uses heart rate and speed (or
power) to determine how a workout affects your
