It looks like the new 620 can gauge peak oxygen volumes, and estimates race times based on likely endurance, the HRM-Run, measures gait with an accelerometer and suggests days off based on heart rate history.
- Supports new HRM-Run HR strap for Running Dynamics
- The HRM-Run strap adds tracking of Vertical Oscillation, Ground Contact Time, Cadence (+ usual HR)
用了620幾天(因身處外國早點買到)
很好的一隻錶, VO2 max 同race prediction 同我PB 又真係差唔多(even i did not run at any high speed sessions- as i am in recovery phase)
running dynamics 好得意, 可以看看自己跑姿如何。
優點:
1. 真係好輕,不過又未至於感受唔到個重量既
2. 算易用,一個鍵start/stop,一個鍵 lap
3. 有 iPhone 好方便,bluetooth BLE 長 connect,一跑完即 upload
4. Auto lap 好清楚
5. 震同beep都好清楚
6. Data screen 可以 customise,亦都易睇
