一、前言在评定运动员的身体适应性的时候,会出现测试条件不适当和不能发现特定的运动员的长处与适应性这种现象。例如,游泳运动员在水中(水的阻力)显示了惊人的能力,但是在陆上的测试中,却不能充分发挥其能力。象这种测试条件的主体,就是准备多大的负荷(负重)。爆发力(功率)的测验也是同样,根据负荷条件的大小,功率的大小而不同;另外,其直接因素——力量和速度的关系也发生变化。 I. INTRODUCTION In assessing the physical fitness of athletes, there is a phenomenon that the test conditions are not appropriate and the strengths and aptitudes of specific athletes can not be found. For example, swimmers show amazing power in water (resistance to water), but they do not perform well in land-based testing. Like the main test of this condition, is how much load (load). The test of explosive force (power) is also the same, depending on the size of the load condition and the magnitude of the power. In addition, the direct factor - the relationship between force and speed also changes.
