The results shows that students in the eastern primary school are superior and statistically significant to the ones in western China (P<0.05). Overall elementary student body shape, function and urban primary school student physical qualities shows a trend of widening, in contrast to overall rural elementary student physical quality that shows a trend of widenening. Eastern and western elementary student body shape development is expressed in a long-term trend growth with a decline in lung capacity (P<0.05) where western students are less than eastern. Eastern and western elementary students endurance running shows a decline whereas body pull-ups capabilities inclined and have statistical significance (P<0.05). Differences of physical quality between eastern and western students are obvious, with eastern primary school students showing better physical quality in terms of quantity, range and speed, but with number, size and speed lower than western students.
