Yes, if you activate this feature. If you wish to allow athletes to deactivate themselves so they can stop receiving reminders and notifications when they are in off-season, holidays or have a long term injury, open Team settings-General-Other, and set the Allow athletes to deactivate account option to Yes.

To edit reminders sent to staff and athletes when an account is deactivated, open Reminders & Notifications - Others and select the gear icon. 

As a result, athletes will be able to deactivate their account for a specific period. An email notification is automatically sent to staff users linked to the athlete account.
