In addition to testing your range of motion, RPM² collects information on bilateral equivalence during a run. After calibrating your inserts and setting your run time, you’ll click “start” to begin your run. Your device will alert you when the run time is complete, and several measurements will appear on your dashboard. To measure run gait, the RPM² device obtains data from five different 10-second segments of your run. One segment is taken from the beginning of the run, three are taken in the middle, and one is taken at the end. This strategy helps determine whether the runner remains consistent throughout the run or breaks down at some point. Here’s how you can interpret the data and use the information provided to improve your running performance.

• Step Time: Measured in milliseconds, the step time reading compares the right and left legs and shows how gait holds up or breaks down during the run. If step time increases throughout the run, this can indicate fatigue or improper mechanics, both unilaterally and bilaterally.
• Ground Contact Time: Also measured in milliseconds, ground contact time is the amount of time your foot maintains contact with the ground with each stride. When this measurement increases, the runner is moving out of gait, resulting in a slower and less efficient run.
• Flight Time: The flight phase is the portion of your stride in which neither foot is in contact with the ground. Flight time is measured in milliseconds, and like ground contact time, an increase in this measurement indicates a gait issue.
• Cadence: This is a measure of steps per minute, and the goal is to maintain a consistent cadence for the full run. A decrease in cadence can show fatigue or poor mechanics.
• Pace: The pace reading is a measurement of miles per minute. A decreased pace from the first 10-second segment to the last points to fatigue and improper mechanics, just like step time and cadence. The goal is to maintain the same pace from start to finish.
• Pressure: Measuring the force applied to each quadrant of the foot during the five measured time segments, the pressure reading shows if the force migrates to different areas of the foot during the run. If this is the case, a breakdown of mechanics is likely, which indicates the need to address weak areas during training.

We’ve already talked about the range-of-motion and running exercises used to monitor bilateral deficiencies with RPM², and now we’d like to introduce you to our cycling analysis. The objective data provided by our state-of-the-art product during four different cycling tests offer you and your trainer valuable information regarding bilateral pressure on the pedals and whether your feet are in the correct position when cycling.

Cycling App Tests

The RPM² device offers four cycling options, all of which take several equally distributed measurements throughout the ride to determine if your cadence, bilateral pressure, and power change or remain the same from start to finish.

• Distance: In this training mode, you choose a ride lasting from 30 minutes to 6 hours, and five separate measurements are taken.
• Time Trial: This mode allows you to choose rides lasting 20, 30, 45, or 60 minutes. For each option, three measurements are taken at the beginning, middle, and end of the ride.
• Interval Training: Five ride options are available in this mode, ranging between 1 and 30 minutes. Depending on the ride’s length, one to three measurements are taken.
• Sprint Training: Offering several ride options of 10, 20, or 30 seconds each, this training mode takes one measurement during each ride.

Interpreting the Data

After completing your distance, time trial, interval training, or sprint training exercise, your dashboard will present three levels of reports. On level one, you’ll see a series of yellow foot icons. Clicking on these will take you to your crank dashboard at level two. This view shows two bar graphs (one pertaining to each foot) at a dozen points on the crank, which allows you to see how your foot pressure on both sides may change at different points in the rotation. In this view, you can also see your cadence and power numbers. If you click on any of the 12 points in the crank, you’ll be taken to level three, which shows the bilateral pressure used at that point. This can tell you if one leg is doing more work than the other. Pressure pie graphs on the four quadrants of the feet will additionally show if you are placing your feet square on the pedal, or if you are pronating or supinating them.
