Episode notes
Danger Of Adolescents In Adult Brackets
- Dr. Jen Case describes competing against 13–14 year olds in adult advanced no-gi divisions and the safety issues that arose.
- She recounts putting one to sleep with a choke and another injuring her spine because adolescents didn’t tap or have adults to call the match.
Treat Tournament Sparring As A Different Animal
- Recognize that tournament intensity exceeds gym sparring and opponents won’t protect you.
- Parents and athletes must not equate gym rolls with competitive matches and should plan accordingly.
