Garmin Premium Soft Strap ANT+ HRM4-Run Sensor
HRM-Run heart rate monitor provides the most advanced running metrics to high-end Garmin Forerunner running watches, including the Forerunner 630 and fenix 3 HR. This real-time data can help athletes take their performance to the next level.
It provides advanced heart rate and physiological features - VO2 max, lactate threshold, recovery time estimates, stress score, performance condition and predicted race times - as well as 6 running dynamics measurements - cadence, vertical oscillation, ground contact time, vertical ratio, stride length and left/right ground contact time balance.
- PHYSIOLOGICAL METRICS - *
Estimates the level of effort at which fatigue rapidly increases in terms of a runner's heart rate and pace.
Measures heart rate variability to make an assessment of a user's overall level of stress.
Provides a real-time fitness-level measurement relative to a runner's average baseline, which indicates performance readiness for the day's workout or race.
- ADVANCED RUNNING DYNAMICS - **
Measures the length of a runner's stride in real time - a metrics which can be used to predict race finish times.
Left/Right Ground Contact Time Balance
Measures a runner's ground contact symmetry, which some runners have found to correlate with injuries or strength imbalances.
The cost-benefit ratio of vertical oscillation to stride length, serving as one indictor of a runner's efficiency.
- RUNNING DYNAMICS -
The number of steps per minute. It displays the total steps (right and left combined)
The bounce in your running motion. It displays the vertical motion of your torso, measured in centimeters.
Ground Contact Time
The amount of time in each step that you spend on the ground while running. It is measured in milliseconds.
