>If the place you live has stronger gravity, then you need more muscle mass to withstand it. I think beings raised in a high-gravity environment would naturally evolve to become stronger than those raised in a low-gravity one.

>Strictly speaking, you would say that, due to the increased gravity, the neural network in their cerebellums was being optimized more efficiently, since it's the cerebellum that handles the acquisition of motor skills.

>When you're first exposed to higher gravity, the sensors in your inner ear (semicircular canals) begin outputting at a greater rate than usual, and that signal strongly stimulates your cerebellum.

>It's believed that, if you then perform training under those conditions, the increase in the rate of synaptic transmission (cell-to-cell communication mediated by synapses) that's generated in order to minimize movement errors (the difference between the movement you intend and the movement you physically perform) is greater than under normal conditions, which in turn speeds up motor skill acquisition. This is the mechanism that operates in the brain under hyper-gravity conditions which increases your physical abilities. It's also our best explanation of Dragon Ball's gravity training with our current understanding of neuroscience
