I had a friend tell me about this company and their products: www.firstbeat.com/
This is taking wearbale smart devices to the next level... this is not just your basic pedometer, this captures so much more data.
Few words from the company web page:
Firstbeat has developed an innovative heart rate variability based analysis technology for measurement of stress, recovery and exercise. Our software products can be applied to improve performance and well-being in sports and at work. We provide information that is rich in detail about exercise monitoring, stress assessment and recovery.
They have a whole host of product and services geared around this, whether you are a Pro, for work and wellbeing, or simply a consumer (you can pick up a Suunto with Firstbeat features included).
Anyway the product that most excites me is the Firstbeat Bodyguard 2
Rechargeable battery (last app. 6 days)
Storage capacity app. 20 days
IP class IP52
Weight 24 g
Measurement accuracy for heartbeat recording1 ms (1000 Hz)
Measurement accuracy for movement:
Sampling frequency 12.5 Hz
Resolution 8 Bit
Data from Bodyguard 2 can be downloaded directly to Firstbeat programs (analysis server, Firstbeat SPORTS)
Data download and battery charging is done directly via the USB-port
So connect this to your chest and after three days have some hugely important data not just about HR, but stress, physical activity/exercise, training effect and many more.
I'm looking to test this out in the very near future... stay tuned.
