Change of Direction ("CoD")is a training form where the athlete performs horizontal movements (running, jumping, skating,...)
while also changing direction one or more times during the rep.
Some common examples of CoD exercises are:
- 5-0-5 (run 5 meters, change direction and run the same 5 meters back and finish at the start position)
- Of course, you can replace 5m with any length
- 5-10-5 (run 5 meters, change direction and run 10 meters back and then turn again, running the remaining 5 meters to the start position again)
- Just like 5-0-5, the distances can vary depending on what type of training is done
- Shuttle run (Run back and forth between two markers)
- This can be customized in various ways, for example to have ever increasing distances or by having the end position further away to make the final phase longer.
Phases
The parts of a CoD run are called phases and each CoD run has at least two phases (because otherwise there would not
have been a change of direction). Phases are named 1a, 1b, 2a, 2b except when the run consists of exactly
three phases, in which case they will be named 1a, 1b and 1c instead.
For every phase, the 1080 software records time, speed, force and power. It also provides total time and distance for the
entire run.
Parameters
The following parameters control how the machine records the run
| Parameter | Description |
|---|---|
| Run-up distance | Used when a flying start is desired. The machine will not start to record measurements until the athlete has moved this distance. |
| Minimum number of turns | The machine will keep measuring until at least this number of turns have been made. This is primarily used to allow the athlete to cross the end |
| End position offset | The default behavior for a CoD run is that the finish line is the same position. By setting this number, the end position can be moved, relative to the start position. The value is expressed as an offset, where a negative value means the end is behind the athlete's start position and a positive value means it is in front of them. |
| Start direction | Can be set to make the machine not trigger accidental starts. The default is to automatically detect which direction the athlete is moving. |
If run-up distance is used together with end position offset the end position is calculated from when the machine
starts measuring, after the run-up distance has been covered.
