chosen.content: See How They Run
  Beautiful, strong, and intelligent, the cheetah holds the world record as the fastest land animal. But what makes these big cats so fast? Through discovery and observation, scientists have uncovered the secrets behind their incredible speed. 
  
  Faster Than We Thought?
  For a long time, scientists thought that cheetahs ran faster than they actually do. In 1957, they set 70 mph (112 km/h) as the cheetah's average speed, with the maximum possible speed between 50 and 80 mph (between 80 to 128 km/h), but not all scientists agreed. Then in 2012, Sarah, an 11-year-old cheetah living at the Cincinnati Zoo, ran 330 feet (100 m) in just 5.95 seconds. Her top speed was 61 mph (98 km/h). 
  
  How They Hunt
  One fallacy that hung around for quite a while was that cheetahs hunted at full speed. However, after tagging cheetahs with GPS collars and watching them hunt, two 2013 studies proved that cheetahs run at lower speeds. They use short bursts of speed for a few seconds before dropping down to a lower speed. One of the studies measured the average speed range at 25.7 to 40.9 mph (41.4 to 65.88 km/h) and the maximum speed at 57.9 mph (93.24 km/h). The researchers divided the hunt into two phases. At the start of the hunt, cheetahs run at full throttle to overtake their prey, then slow down as needed. The cheetah's acceleration power gives it a decided advantage over its prey. 
  
  A Running Machine
  Cheetahs were designed to be the speedsters of the animal world. Their arm and leg bones are as long or even longer than a human's femur and humerus. The small narrow heads, long supple spines, and slender bodies are aerodynamic, making them cut through the air like greased lightning. Cheetahs are packed with fast-twitch muscles they use for fast acceleration. They also have a larger-than-usual rib cage that lets them breathe faster and deeper and helps keep them cool.
