# How to test: Load Velocity Sprint Profile

[Load-Velocity Profiling Best Practices](https://player.vimeo.com/video/1121193736?h=7d9f3c9cb1&badge=0&autopause=0&player_id=0&app_id=58479)

## Load Velocity Profiling

Watch the video and read below to learn best practices to profile athletes running with resistance using the 1080 Sprint 1 or 2.

Using the Sessions app on the 1080 Sprint 2 or the Control App Sessions feature allows you to record three resisted runs to capture the necessary data to provide a load velocity graph and speed decrement table.

## Choosing loads

Load selection based on type of movement (i.e. sprinting) are different for different type of athletes. Be mindful to have greater than 3 kg seperation between resisted repetitions. Select loads that are in the range that you plan to practice in for the type of exercise being tested. If a high vdec is desired, then it's better if the load velocity profile also contains higher loads.

Here is a sample of loads for a trained athlete using the Sprint 1 or Sprint 2 device.

Sample Sprinting Load Velocity Testing Protocol

1. 2 kg resisted sprint -> 30 meters or yards
2. 8 kg resisted sprint -> 25 meters or yards
3. 14 kg resisted sprint -> 20 meters or yards

- **Graph:** The graph shows speed on the *y-axis* and machine load on the *x-axis*. The line corresponds to the change in speed as the load changes.
- **VDec Table:** Calculates the velocity decrement in 10% intervals from max speed of the movement. Determine appropriate training load to meet the desired training speed of the movement based on training goals. Save to Profile allows this data to be easily used for training within the 1080 professional software.
- **$R^2$ value:** This is a measurement of how well the line matches the actual measurements. A value of 1.0 means the line intersects all included measurements. A value below 0.9 is considered poor. Ideally values >.95 are expected with full effort repetitions.
- **$M_0$ value:** This is the *theoretical* max load for this exercise. Client is not expected to actually be able to use this load since the speed would be zero. This load is specific to the 1080 Motion motorized device.

## Creating a Load Velocity Report

[Video](https://cdn.document360.io/2720a32a-6d48-40c3-870e-0cf3536ac843/Images/Documentation/LV%20Profiling%20Part%202.mp4) The report can be created from within a *group training* session, as well as from the *browse data* interface.

**From *group training***:

1. Perform a minimum of three runs or reps at different loads  (See [choosing loads](/v1/docs/load-velocity-profiling#picking-loads) below)
2. Enter "select mode"

1. Select the runs or reps to include in the report.
2. Once selected, click on *Load Velocity* button:

**From *Browse Data***:

1. Perform (at least) three runs at different loads. Please note, the runs or reps need to be completed in the same set
2. Click on the *Load Velocity* button:  

![L/V Button (Browse Data)](https://cdn.document360.io/2720a32a-6d48-40c3-870e-0cf3536ac843/Images/Documentation/lv-button-browse-data.png)

### Save to profile

By saving the load velocity report to the *client's profile* it will become available in future training sessions for exercises of this type as a way to [set load from velocity decrement](/v1/docs/set-load-from).

- For linear sprint exercises, the saved report will be usable with any linear type sprint exercise.
- For single rep type exercises (i.e. squats, pulls, presses), the saved report is only available for that particular exercise.
