Comparison And Analysis Of The Body Shape, Age, Technical Index Between NBA And CBA

Though using the literature, mathematical statistic, comparative analysis and logic analysis to compare the NBA and CBA players'height, the weight, the weight/ height index, the age, the rebound, the assist and the point for nearly nine seasons, the results showed:1)There was a very significant differenc(eP<0.01)for the average height, the weight, the weight/ height index in the NBA and CBA respectively different position as well as NBA and CBA identical position. All were center>forward>guard. 2)Compared the average age in different position player of NBA, there was a very significant difference(P<0.01)between forward and center ,forward and guard .All was center>guard>forward; There was no significant difference found for different position player in CBA, and forward>center>guard. There was a very significant difference(P<0.01)between NBA and CBA's identical position. The NBA players'frequency distribution in five age sections(≤22years old,23-26 years old,27-30 years old,31-34 years old and≥35 years old)was normal which there were more players in 23-30 years old than other age sections, while the CBA was abnormal which the distribution quantity of players in each age section was reduced along with the age increase. 3)There was no significant difference between forward and center for rebound in NBA, while there was a very significant difference between the forward and guard ,center and guard. There was a very significant difference between forward and center, center and guard in CBA. There was a significant difference(P<0.05) between forward and guard. There was a very significant difference between NBA's and CBA'S forward, NBA's and CBA'S guard. All were center>forward>guard. There was a very significant difference(P<0.01)for assist in different position player in NBA. There was a very significant difference(P<0.01)between center and guard in CBA. In addition, there was a very significant difference(P<0.01)between NBA's and CBA'S forward, NBA's and CBA'S guard. All were guard> forward>center. There was a very significant difference(P<0.01)for point between forward and center, center and guard in NBA, and guard> forward>center. In CBA, there was a significant difference(P<0.05) between forward and guard , and a very significant difference between center and guard, and center>forward>guard. There was a very significant difference(P<0.01)in the same position of NBA and CBA. 4)The quantity of NBA and CBA's rebound ,assist and point have strong position characteristic, but they were positively correlated with the NBA professional age, and negatively correlated with age. In contrast, the three technical indexes of CBA were positively correlated with age.
