Cheetah vs Greyhound Speed Test | BBC Earth

so mate today slo-mo is all about speed and let's face it the cat's already won kind of don't want to agree with you on that one but I'm gonna have to yeah fastest land animal the cheetah I mean the BBC has filmed some great cheater footage in the past and you just see why there's such speed demons so what's the the key behind why they're so fast well they got this really flexible spine which gives them a massive gate really spreads out their legs and they got these incredibly powerful back leg muscles to really drive them forward but this semi-retractable claws so basically they're closer partly out all the time right like one of spikes giving them excellent grip that's just credible and really streamlined very powerful animals okay now so cheetahs are pretty cool but how about getting the greyhound the fastest dog in the world get that in slow-mo so we've got two dogs a city and sweet we're gonna race for us and we've got to you so that one of them can have a rest while the other ones racing and she's got such big powerful legs oh come on get over it with the aid of the vampire Batmobile which is really we have to get some awesome shots of these guys emotion will shoot this on a relatively long lens just so we can keep a bit of distance in the dogs we're about to go for the first run [Music] oh I'm gonna get away please [Music] [Music] [Music] [Music] [Music] I'm really pleased we got the beginning that's great can you see that I'm not flying yeah and that's and that was off the front feet I predicts me yeah yeah yeah really dug in stretches out that they so like a teacher if they run in a star called rotary gallop which is worth a feat basically land in a circular position as it go around is that front left from right back right back left is that circular rotary gallop we talked about and that she can really see there's two flight phases so when their feet are off the grounds they're either fully extended or tucked up to the body just like a cheetah that was pretty quick dunk what kind of speeds will be clocking there cuz we've just a bit overtaken him so yeah he's certainly doing 43 plus miles an hour so T's faster than a greyhound why is that yeah well she wants to look at that it's not all that clear because they're running really similar style but basically some researchers at the Royal Ventura College in London discovered the greyhounds aren't very good at increasing the frequency of their stride whereas cheetahs are really good at swinging their legs forward and it's just building up that was awesome and now it's from the head honcho [Music] [Music] so I think we've done the Dukes injustice today you have I think she deserves a lie down so the debate still rages on cats versus dogs what do you think [Music]
