Human development from birth to adulthood is a continuous process that requires key physical, mental, emotional, and cognitive stages.  Children  ages 6-16 should focus on refining general fundamental movement skills.  An area of importance is speed training which includes activities such as acceleration and deceleration mechanics, rapid changes of direction, cutting drills, & agility that contributes to the Long-Term Athletic Development model. Bodyweight strength training is another essential area where athletes will learn to control their bodies/limbs during sports activities in skills such as planks, push-ups, and squats to lay the foundation for progressive strength training methods throughout human development.
