Final answer:
Periodization can protect against overtraining by allowing for proper rest and recovery.
Step-by-step explanation:
Periodization can protect against overtraining by allowing for proper rest and recovery. Overtraining occurs when the body is subjected to excessive stress without adequate time for recovery. By implementing periodization athletes can strategically plan their training program to include periods of higher intensity and frequency followed by periods of lower intensity and increased rest, allowing the body to recover and prevent overtraining.
