Configuring exercises for automatic injury substitution
The substitutes and body parts metadata are used together to prescribe appropriate exercise substitutes in case of injury. You can configure how you want automatic substitutions to work for each exercise.
The body parts section allows you to specify which body parts are used in the exercise. It's important to make sure that this information is accurate for all the exercises you commonly use. This is because FYTT allows you to record an injury to a specific body part for an athlete, and if the athlete is prescribed an exercise that utilizes the injured body part, then the system attempts to make an appropriate substitution.
The "Sided" toggle allows you to indicate whether or not the exercise can be performed one side at a time (unilateral). This setting is important, because FYTT can substitute a unilateral exercise in place of a bilateral exercise if an injury only affects one side of the body.
We understand that there may be some ambiguity as to whether or not a body part is utilized for a given exercise, but we recommend using a basic heuristic:
If an injury to a body part would prohibit the safe and proper performance of the exercise, then that body part should be marked as included for the exercise.
For any exercise in the database you can define substitute exercises that can be used in its place. If FYTT detects that an injury interferes with an exercise you've prescribed, it will look to see if you've configured any substitutes that would avoid the injury.
Substitutes should ideally include exercises that roughly accomplish the training objectives of the original exercise while avoiding injured body parts. This might include exercises that can be performed one side at a time or that put a lesser demand on key body parts such that an injury would not interfere with their performance.
Note that any substitute exercises will also need to have accurate body part configurations in order for the substitution logic to work properly. In other words, if you include Barbell Lunge as a substitute exercise for Back Squat, make sure that you configure the body parts used for Barbell Lunge (in addition to configuring the body parts used for the Back Squat).
It's generally a good idea to loop in athletic trainers when configuring exercise body parts and substitutes.
