Data from a Wingate sprint test can be used to create an analytical function that gives power during a sprint. Maximum power, average power, time at maximum power, and total work are calculated for the data.
Power Profile Function
When a rider commits to a sprint, power increases rapidly, reaches a peak and then trails off. The shape of this power curve is reported to be about the same for most riders. Magnitudes change, but the basic shape stays the same. Data for power curves can be taken in a Wingate Test where a load is suddenly applied to a bicycle ergometer and power is measured over 30 seconds. Or data could be taken on a bike using a power measurement device such as an SRM. If one has such measurements, it would be useful to put them in the form of a function that can be used in quantitative calculations. This section discusses how to do this.
Power Profile From Wingate Test.
The data in the sample input was collected for a real sprinter in a Wingate Test. These data yielded a power profile for the sprinter, and this power profile is plotted below. This power profile was then used to estimate maximum power, time at which maximum power was reached, average power during time period, and total work during time period.
