Now the sensor in your Nike+ can connect to an iPod and record your workouts. Its as easy as finding an iPod-compatible cardio machine at the gym and tracking your progress from one workout to the next. Minute by minute, mile by mile, you will be motivated by more than just from your iPod's tunes. Connect your iPod Nano, iPod Touch, or iPhone 3GS to your cardio machine - record your pace, time, and distance as you work out, and when you've completed your workout you will receive voice feedback of all your stats in addition to the calories burned.
The Nike + iPod also works outside the gym.
The process involves three stages: The Capture, The Sync and The Share.
Nike+ CaptureThe shoe sensor's accelerometer measures the amount of time a runner's foot is on the ground, which is inversely proportional to speed. Transmitting at 2.4 GHz, the sensor sends data to a receiver that's either attached to an iPod Nano or built into the second-gen iPod Touch.
Nike+ SyncAfter the workout, the iPod is synced to a computer running iTunes, which automatically sends the data, including start time, duration, and distance, to the Nike+ servers, formatted in a specially structured XML file that can also be read by third-party and open source apps.
Nke+ ShareUsers can access their run history at NikePlus.com, browse through a graph that shows all their activity, and then drill down to details about each workout. If they need more motivation, they can enter challenges or set individualized goals, like running 100 miles in a month.
You can set a distance goal, or a time goal and during your run the system will also tell you (using a voice that interrupts the tune or podcast you are listening) how far you have run and how much time is left in your run.
Another nifty feature is the ability to save the run's performance data in Nike+'s database via itunes. You can just sync up your iPod's saved info when you log onto iTunes. Your stats can then be transferred to the Nike website where you can continue to track your progress over time. In addition there are a good number of contests throughout the year one can register for and there are even song playlists from other runners that you can obtain.
Overall it is a great system and one that can motivate even an avid couch potato like myself to start running... and in the process... hear the burn!
