Forerunner 620: The Coach on your Wrist
A coach is a philosopher, a grizzled veteran, a guru, a tinkerer, an analyst, an authoritarian, and an advocate. Most importantly a coach knows how well you can perform. Now you can hold yourself to those same standards with the effective features on the Forerunner 620. The watch might just know your abilities better than you do.
It starts with a feature called the VO2 max estimator. After running for 10 minutes or more with the Forerunner 620, it calculates the maximum volume of oxygen your body can use.This metric is an important factor in your overall aerobic endurance, and should increase as you train.
That brings us to the recovery advisor. When paired with the HRM-Run heart rate monitor, it takes the guesswork out of planning recovery time between hard workouts. Just like a coach, it studies the runner and their physiology based on heart rate data.
Other capabilities of the 620 and HRM-Run:
Cadence — The cadence feature records the number of steps per minute. This feature counts total steps (right and left combined). Previous devices used a foot pod to measure foot strike rate.
Vertical Oscillation — The verticaloscillation shows the degree of 'bounce' in your running motion. Vertical oscillation is measured in centimeters from a fixed point on your body (sensor on the chest mounted HRM-Run monitor). Typical oscillation is between 6 — 13 cm. Elite runners generally oscillate less.
Ground Contact Time — The Forerunner 620 measures how much time, during the running motion, your foot is on the ground rather than in flight. Ground contact time is measured in milliseconds. Most running ground contact times are between 160 — 300 milliseconds. Elite runners typically spend under 200-milliseconds in contact with the ground each step.
