| Abstract: | By applying three-dimensional strength-testing consoles and dynamic strainometers etc, dynamic tests and studies were made on specific skills of the elite collegiate male long-jumpers. At the same time with the analysis of the run-up speed, the three-dimensional contact force and its transmission features between the feet and the ground when beating the board. Meanwhile, the jumpers' frequency of movements of the limbs, the relationship and variation rule between the length and the rate of strides as well as the dynamic effects. The results of the test showed that there existed distinct differences of dynamic indexes between the elite collegiate male long jumpers at home and the elite athletes abroad. |
