What is a good ape index 0 (arm-span equal to height). Using the same calculation, this person would then have an Ape Index of +10. They become more extreme with shorter arms and so the force required goes up exponentially as that angle gets really small. There are 2 MWs in the top 5 of greatest ape index measurements, and 3 more in the top 5 of greatest leg proportion measurements. Ape Index= 6’8 – 6’4″ = 4″ If we are working in the metric system, however, this same person would have a height of 193 cm and an arm span of 203 cm. 9 if Ape index >0/5. A typical ratio is 1, as identified by the Roman writer, architect and engineer Vitruvius prior to 15 BC. Dressel’s wingspan is 193 cm (6’4″), and his height is 191 cm (6’3″). k. “For a positive [or higher] Ape Index, look for entering the water too close to the head or exiting the water before the hips. mhqekyiuaiqinbqjiiongqavwbjnmmocyclofsffeqrruvaqyeqktdydnnuubqatxglod
