Deep Dive:
- The Fitness-Speed Pipeline, and the ever-present argument about what comes first
- More is not always better, especially with high-intensity activities
- The physiology of sprint training, sprint mechanics and plyometrics
- Motor learning, brain training and body positioning
- The integration of strength training with sprint training.
- CNS fatigue
- Stride rate & stride length
- Coaching challenges
Webinar Pitch, Outro & Feedback
