The use of legally prohibited stimulants by the players for "functional" physiological stress will expose them to many injuries as they will exert an abnormal "industrial" effort that is not appropriate for their physiological abilities. The athlete's medical professional and trainer should also write a book listing the injuries of each player:
- Where the injury occurs (open, covered, in any winter or summer season).
- The moment of injury (during warm-up, during the game, at the end of the game).
- The player's physical condition at the time of injury (muscle strain, nervous pressure).
- The level of the tournament in which the player was injured (easy game, tough match, final).
- Detailed description of the movement that led to player injury, so as to take advantage of this book when diagnosis, treatment and follow-up.
