# Variable Load

[Video](https://cdn.document360.io/2720a32a-6d48-40c3-870e-0cf3536ac843/Images/Documentation/1080%20Sprint%202%20Variable%20Loading%20(5).mp4)

This is a function available on the 1080 Sprint and Sprint 2 that enables advanced resisted acceleration and speed training within the same single sprint repetition. It is currently only available using the 1080 Control App.

The variable resistance feature is available in the load setting window. You activate this feature by selecting the “Variable load” button.

It will decrease or increase the load as the athlete accelerates and the speed increases. Moving from higher to lower load is beneficial for training with a higher resistance in the initial acceleration phase but thereafter transition into to a lighter load once the athlete reaches a higher speed. This is suitable to optimize the training for the entire sprint distance initial acceleration and throughout the full running distance.

Parameters:

1. The *Start load* is the load when the machine is idle and athlete is standing still
2. The *Target load* is the load the user will feel when the speed reaches the preset target level ("Target Speed")
3. The *Target Speed* is the speed selected at which the *Target Load* will be reached. The lower the  

value, the sooner the *Target Load* resistance will be reached as the athlete accelerates  

Variable load is also useful when using the system for assisted sprints. It enables you to provide a  

higher initial pulling force from standstill (*Start Load*) which will help the athlete reach max  

speed faster. The load will taper off or increase to reach *Target Load* value as the athlete's speed  

increases.
