Group Fitness ANT+
by: FrankAndroid • 9
Simultaneously display multiple Heart Rate Monitor (HRM) belts values using the ANT+ protocol. Useful for Cardio-Fitness, Spinning class and Gym fitness workouts, to easily display and control the training activity of up to 8 persons. HR reading of each trainee is displayed as relative % and absolute value.
If supported by your device, all readings can be output to TV via HDMI See my setup (8 devices) in the screenshot.
The training instructor can at once see all the HR values, and suggest better and personalized training activities accordingly. Colour changes according to fitness zone (65%, 75%, 85% and 90%). Maximum HR can be set with equations based on age/gender, or to a fixed value if known (through Metabolic Assessment at a specialized centre). Stopwatch now available when starting recording the session.
This is Full version, with up to 8 channels, settings storage (association of channel to a specific belt, user name and age/gender or Max HR) and possibility to record to file in CSV format, for email/sharing at the end of the session.
More features are on the way, such as additional options for the selection of equation to obtain %HR (now set to the male-female equations as in http://www.digifit.com/heartratezones/maximum-heart-rate.asp ), introduction of calories counter and edit fitness zone thresholds, and internal plotting of training sessions. For plot now you should send to yourself the CSV file by email and plot it using MS Excel (Scatter plot XY).
You MUST have an Android Device with ANT embedded chip and install the Dynastream ANT+ Service available at: http://bit.ly/IkV4gu
See the link http://bit.ly/IkV4gu also for ANT+ native support devices!!
As alternative, you should plug a ANT+ compatible USB key to your Android device (using an USB adapter if necessary), and in addition install also the USB Service from Dynastream available at: http://bit.ly/TPlpGq
All HRM belts used MUST be compatible with ANT+ and endorse the ANT logo. More info at http://www.thisisant.com

Setup in a large room
An installation in a Gym room can be done using a MK808 Android TV pen, with an ANT+ USB pen supporting up to 8 HRM ANT+ belts. The MK808 has HDMI output to display data on a large LCD TV (via HDMI) to show HR values to both instructor and trainees. Coverage, according to ANT+ specifications, is in the range of 10 meters, so please check connectivity in the final premise with the Demo. For more information please contact me to adapt the software and select the Hardware for your needs!!!
