Resistance Control Bar

Users control the motor by changing load, mode and speed controls within the Resistance Control Bar.

It is accessible to the user in two locations with minor differences in presentation.

1. Sessions App

3. Tablet/Laptop remote control software

Load

• On the left of the Control Bar, resistance and assistance are controlled independently
• CON (Concentric) or Resisted load is resistance felt moving away from the machine
• ECC (Eccentric) or Assisted load controls the pull moving toward the machine
• Load on the 1080 Sprint 2 is constant by default. Turn on variable resistance by selecting the CON or Resisted load number and selecting Variable.

IMPORTANT: When increasing the assisted load, the system will automatically decrease the assisted
speed. This is a safety function to prevent an overly high assisted load and speed to be applied by
mistake. The assisted speed must be raised again to the desired level after modifying the assisted load.

Pause and Resume

This button is available on Generation Two products (Sprint 2, Cable) and allows load pulling from the motor to decrease to 3 kg with the push of a button. It ONLY pauses resisted and assisted load and allows the current set speed limits to be active.

This button allows load to immediatley be suspended when pressing "PAUSE LOAD" and move to a new location or relax under very light load (<3 kg).

When in set position to receive previous load, hold down on the RESUME LOAD button to return to previous load, mode and speed settings.

Mode

The machine has three different resistance modes. These can be changed during operation. Be advised to notice the difference 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

Select the gear icon when using the tablet remote control software to change 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.

Speed Limits

The speed limit settings control how fast the line is allowed to move away or toward the machine.

Resisted speed limit

The Resisted speed limit prevents the user from moving faster than the selected limit. The machine limits the speed to the set limit by temporarily increasing the amount of resistance, thus decreasing the speed. The Resisted speed limit creates an isokinetic resistance mode.

Restricting the resisted speed is primarily used in swim training or rehabilitation. It is not a useful function for sprinting or running and will cause a sudden jolt if the user accelerates into the speed limit.
To avoid this, simply dial in the maximum resisted speed value: 14 m/s.
The lowest speed limit allowed is 0.05m/s.

Use load to regulate how fast the athlete is allowed to run!

Assisted speed limit

Set the assisted speed limit higher than a person can run, jump or perform change of direction exercises. For example, set the assisted speed limit to 14 m/s for an overspeed sprint exercise to prevent the line from dragging on the ground.

The assisted speed limit prevents the line from retracting faster in the assisted direction than the set limit, even if the user lets go of the line completely. The machine reduces the assisted speed by temporarily decreasing the amount of resistance

None or Pulley Gear

To utilize resisted loads higher than 20 kg and assisted loads higher than 30 kg you will need to attach a pulley between the machine and the athlete. The pulley will double the maximum allowed load at the cost of half the maximum allowed speed (down from 14m/s to 7m/s when using the pulley).

To get the correct data when using a pulley on the line you need to put the 1080 Software in Pulley gear.

Learn how to set up pulley gear here.

Set Zero Position

All 1080 machines have a notion of a zero point, sometimes also known as a calibration point. This is the position where the machine will stop retracting the line.

1080 Sprint 2 machines will set the zero point when turned on (without having to connect any external software).

Choosing a Zero Position

When using the machine resistance control bar, click on the mode button and you can Set Zero Position by pushing the button. This willl allow you to pull the line out with minimum load. Set the new position manually by clicking NFW. You may now return to full screen mode.

It's important that the zero position is set in such a way that the rep never enters the "no pull zone". The exact size of the safety zone depends on the exercise.

set-zero-position

When using the tablet remote control software, select the gear icon to access the Set Zero Position

When done with a session and turning off the 1080 Sprint 2, please Set Zero Position and allow the line to fully retract to the default resting position.

Reps

Usually a safety zone of 10-15 cm is enough.

Resisted sprinting
The safety zone should be at least 1m wide. This is to ensure that the line is fully tensioned before the run starts

Assisted sprinting

The safety zone needs to be wide enough to allow the runner to slow down before reaching the zero position. Learn more here.

The exact length depends on several factors, including how fast and how far you run, but also things like the surface material and type of sport.
