How do cheetahs maintain their high-speed chases, and what physiological adaptations allow them to reach speeds of up to 70 mph (113 km/h)?

Cheetahs have several adaptations for speed, including a lightweight frame, long legs, and a flexible spine that allows for an elongated stride. Their large nasal passages enable increased oxygen intake, while their high percentage of fast-twitch muscle fibers contributes to rapid acceleration. Additionally, their specialized claws and pads provide better traction.
