| 中文摘要: |
| 从国家男排部分上海籍运动员的大力跳发球技术测试效果入手，分析与诊断影响其大力跳发球技术动作的主要因素，并就发球抛球、发球速度的固定等两方面进行具体的分析与讨论。同时对两名优秀选手的腰背肌肉力量进行监测，综合评价其大力跳发球技术动作利弊特征，并做相关的比较研究。经运动学分析，总体上两名运动员的大力跳发球抛球时间偏短、击球点偏低，造成其发球球速慢且失误率高等，并建设性的提出跳发球技术动作诊断应因人而异，最大限度地挖掘个人技术动作的局部潜优势。 |
| 英文摘要: |
| Based on the technical test of the jumping spike serve of Shanghai men's volleyball players in the national team, the article analyzes the main factors affecting the technical movement of jumping spike serve. It also discusses ball toss in serve and the fixation of serve speed. According to the monitoring of the two elite players' back muscle strength, the paper evaluates the technical movements of their jumping spike serve and makes a comparative study. According to kinematic analysis, the toss time of the two players in jumping spike serve is short and the hitting point is low, which results in slow ball speed and high faulty rate. It suggests constructively that the diagnosis on the technical movements of jumping spike serve should vary from person to person, and the partial potential advantage of the personal technical movements should be unearthed to the greatest extent. |
