# Resistance Modes

The machine has three different resistance modes. These can be changed during operation. Be advised to notice the differance between the modes. Data collected in the different modes can not freely be compared. This is especially true for Normal/NFW modes compared to Isotonic mode. As intended, Isotonic mode will always yield a lower pulling force on any given load, compared to Normal/NFW modes

### NFW (No Flying Weight)

When "NFW" is selected the resistance will feel roughly the same as “Normal” during slow movements. During fast movements the machine will become more aggressive in order to decrease the amount of slack in the line.

This is the recommended mode for most types of training.

### Isotonic

In Isotonic mode, the force will be much less affected by acceleration and deceleration. The inertial effects are much lower in isotonic compared to NFW and Normal modes. Inertia will never be zero, because of some internal mass and also from rotating parts.

Isotonic mode is especially useful for assisted sprinting.

### Normal

When “Normal” is selected, the resistance will feel like a normal weight which means that the sense of inertia is present during acceleration and deceleration of the handle. This may lead to some slack in the line when performing fast movements with a high deceleration. To avoid slack, use “NFW” instead.
