[The Sprint - Detailed Biomechanics]
The moment his foot hit the ground, Kai felt the difference.
His enhanced Constitution meant his muscles could generate force beyond normal limits. His increased Intelligence meant his brain automatically calculated optimal stride length, foot placement, breathing rhythm.
Step.
Right foot planted. Leg muscles—now far stronger than any five-year-old's should be—compressed like springs. Enhanced Dexterity meant perfect balance. His body naturally assumed the most efficient running posture.
Push.
Explosive force. His small body launched forward at speeds that made nearby adults do double-takes.
Breathe.
His Intelligence optimized his breathing pattern automatically: inhale for three strides, exhale for two. Maximum oxygen efficiency without conscious thought.
Stride.
Each step covered nearly two meters—impossible for his leg length, but enhanced Constitution let his muscles perform beyond normal biomechanics.
