【Abstract】 Based on the theory of biomechanics, this article illustrates the differences in three techniques, i. e. run-up, take-off and bar-clearing between straddle jump and Fosbury flop. And then it points out the disadvantages of techniques in straddle jump and demonstrates the advantages of techniques employed in Fosbury flop.更多还原
