A male chimp named Boma "Suzette’s father Boma registered one-hand pulls of 847 pounds with his right hand and 640 pounds with his left." Even football players can't do the exact feats that were done by chimps.

Interesting to read, still reading it. Here is one interesting video, which I remembered. Look from 4:27 about a minute if not willing to look whole video. There is quite similar kind of jump and there is easy to see the difference between untrained relatively fit man and then one, who can jump. That jumper is impressive and as everyone can see, very similar kind of jump as on this study when looking at chimp.

Jumping is very genetic, box jumps can be a learned skill though. If you have good hip mobility and a powerful arm swing/explosion off the ground, you can see a lot of growth relative to where you started but if you're talking about the Vertical Jump which is a true test of leaping, no matter how much you train, it's very hard to add significant height to your jump. Sure you can improve but no matter how hard you work, you're never going to have a 40'' vertical leap without a lot of help from the genetic lottery.


"Vertical jumping was used to assess muscle mechanical output in bonobos and comparisons were drawn to human jumping. Jump height, defined as the vertical displacement of the body centre of mass during the airborne phase, was determined for three bonobos of varying age and sex. All bonobos reached jump heights above 0.7 m, which greatly exceeds typical human maximal performance (0.3–0.4 m). Jumps by one male bonobo (34 kg) and one human male (61.5 kg) were analysed using an inverse dynamics approach. Despite the difference in size, the mechanical output delivered by the bonobo and the human jumper during the push-off was similar: about 450 J, with a peak power output close to 3000 W. In the bonobo, most of the mechanical output was generated at the hips. To account for the mechanical output, the muscles actuating the bonobo's hips (directly and indirectly) must deliver muscle-mass-specific power and work output of 615 W kg−1 and 92 J kg−1, respectively. This was twice the output expected on the basis of muscle mass specific work and power in other jumping animals but seems physiologically possible. We suggest that the difference is due to a higher specific force (force per unit of cross-sectional area) in the bonobo."
