METHODS
Figure 1. Stopwatch
Figure 2. Heart Rate Monitor
Our data was collected using 3 instruments. These instruments include a stopwatch and a heart rate monitor and a scale. Data was collected at 4 different times of the day, and for each time of the day, 5 data points were collected.
We used the stopwatch, shown in Figure 1 to measure the time taken for us to complete the 100m sprint. With that time we used to calculate speed, kinetic energy and eventually power.
We used the heart rate monitor to measure our bpm (beats per minute) in order to compare that to our max heart rate so that we can measure the percent of exertion at that particular time of the day. The heart rate monitor was attached to the wrist as shown in Figure 2.
We used the scale to measure our weight and get the value needed for the BMI equation.
GOALS OF DATA COLLECTION
In the data collection process, the time taken to complete the 100 meter run, the heart rate after the 100 meter run, and the mass of the individual were recorded. The data collected allowed us to find the velocity, kinetic energy, power and percent exertion.
The goal of our data collection was to efficiently and accurately determine whether the time of the day affects the intensity of individual workouts by collecting 4 data values: Mass of subject, time taken to complete 100m sprint, and heart rate immediately following run.

SAMPLE OF COMPLETE DATA
This is a sample set of data from one of the three subjects
The full set of our data can be found here:
Graph 1. This graph represents the individual power output at specific times of the day
Graph 2. This graph represents the individual time taken to complete a 100 meter sprint at specific times of the day
Graph 3. This graph represents the individual percent exertion (heart rate/max heart rate) at specific times of the day. Percent exertion is the heart rate after the run compared to the max heart rate for each subject.(Equation 5)
