A running start compared to a straight up jump…..The answer seems pretty simple. I bet Burrows could gain a minimum of 5 more inches If he cheated with a running start. But props to both.
Why would a running start help? Horizontal momentum isn’t going to do anything for you in a purely vertical jump.
Well actually that’s the physics behind a high jump. you turn horizontal momentum into upwards momentum
There is always some vertical component to human locomotion and Jones benefitted from a greater amount of kinetic energy stored in his tendons from his approach. Burrows also had some small amount of kinetic energy transfer from coming up onto his toes and then dropping right before the jump, so neither athlete performed the jump from an absolute dead start but the approach does make a difference.
