From my research there seemed to be four main options to accurately measure the exercise a person claims to undertake.
1. Heart Rate Monitor
- Very easy accessible and cheap
- Can upload information to he internet
- Used by athletes to condition or improve performance
- Can be affected by stress
- Used for tactical training
- Used for motivation already connected to a watch giving immediate feedback to user
- If used near another heart rate monitor can give false reading
The major bonus of heart rate monitors is the fact it can be uploaded to the internet already, but I don't think it would give an accurate reading for resemble a workout as stress effects it also.
- Counts number of steps a person takes
- It is worn throughout the day by a person
- Constant update of how steps you have taken
- Most basic pedometer is the spring-levered pedometer
- Piezo-electric pedometer (accelerometer) more accurate than spring-levered pedometers
- GPS pedometer
This device has numerous advantages can be uploaded to the internet, gives accurate reading but all it is doing is measuring steps undertook in a day which to athletes wouldn't be considered as a workout.
This is a GPS system measuring distance is possible for cycling, running etc. It is a good system to measure distance and speed for a user but a user would have to undertake long hard exercise regimes to give the system useful feedback.
4. Skipping Counter
- Gives accurate amount of skips taken
- Calculates calorie lose
- Motivates a user by itself already
- 70-110 calories in 10mins
- 600-900 calories in 1 hour
- Cheap and easy accesible
- Upload to the internet unknown
This seems to be a suitable device as it measures accurately already is motivational and is not a daunting task for some one to attempt. I'm still not sure if it can be uploaded to the internet I have emailed a few producers of the product to see if it is possible.
