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 maintain their high-speed chases through several key physiological adaptations:

Aerodynamic Body Shape: Their slender, lightweight bodies reduce drag and enhance speed.
Muscle Composition: Cheetahs have a high proportion of fast-twitch muscle fibers, enabling rapid acceleration and bursts of speed.
Long Legs and Flexible Spine: Their long legs increase stride length, while a highly flexible spine allows for greater extension during sprints.
Large Nasal Passages: This facilitates increased oxygen intake, supporting high-energy activity.
Specialized Claws: Unlike other cats, their non-retractable claws provide better traction during running.
