Athletes will be progressed to advanced movement and strength skills as the maturation process develops.  Due to the nature of sport concerning most young athletes, the concept of sport-specific development doesn’t have any implication on training protocols.  Many athletes at this stage of development play multiple sports that require a variety of attributes that are fundamentally grounded upon the principles of strength, speed, movement, mobility, and coordination. 

Academic and athletic demands reach a pinnacle at this stage of development.  To deter over-training, fatigue, and injury, training protocols are designed around the optimal enhancement periods that continually change throughout the Academic year.
