The aim of the research was to implement an athletic program to improve the explosive force in order to optimize physical fitness at the level of elite football-tennis players and evaluate the progress made through specific tests using the Opto Jump. The research included 10 elite European and world-class players, on whom an experimental program was applied in order to improve the explosive force of the limbs in conditions of speed, endurance, and dynamic balance. Study tests: five vertical jumps on the spot, on the left/right leg; five back and forth jumps on the left/right leg; five left/right side jumps on the left/right leg; vertical jumps on both legs 60 s; BFS vertical jumps. For each test, the following parameters specific to the explosive force were statistically analyzed: contact time (s); flight time (s); jump height (cm), jump power (w/kg); RSI-Reactive Strength Index, defined as Height (m/s). In the study, the average value of the parameters specific to the jumps performed in each test was taken into account. During the study, the tests were performed and processed on the Opto Jump device and software. In all tests of the experiment monitored through Opto Jump, significant progress was made in the final test compared to the initial one, which demonstrates the efficiency of the physical training program implemented for the development of explosive force, with an impact on the sports performance of elite players. The most relevant results obtained for the left leg regarding the improvement of the explosive force of the lower limbs materialized in the jump height parameter was in the test of five vertical jumps on one leg on the spot, and for the right leg in the tests of: five back and forth jumps and five left/right side jumps. The most significant advances in the study were in the tests, in descending order of their weight: 60 s vertical jumps on both legs; five back-and-forth jumps and five left/right side jumps, five vertical jumps on one leg standing, and BFS vertical jumps.
本研究的目的是实施一项运动计划以提高爆发力，从而优化精英足球-网球运动员的身体素质，并使用 Opto Jump 进行特定测试来评估进展情况。研究包括 10 名欧洲精英和世界级球员，他们接受了一项实验计划，以提高四肢在速度、耐力和动态平衡条件下的爆发力。研究测试：左腿/右腿 5 次原地垂直跳；左腿/右腿 5 次往返跳；左腿/右腿 5 次左右侧跳；双腿 60 秒垂直跳；BFS 垂直跳。对于每个测试，都对爆发力的特定参数进行了统计学分析：接触时间（s）；腾空时间（s）；跳跃高度（cm），跳跃功率（w/kg）；RSI-反应强度指数，定义为高度（m/s）。在研究中，考虑了每个测试中执行的跳跃的平均参数值。在研究过程中，在 Opto Jump 设备和软件上进行并处理了测试。在 Opto Jump 监控的所有实验测试中，与初始测试相比，最终测试的参数都取得了显著进步，这证明了实施的力量发展物理训练计划的效率，对精英运动员的运动表现产生了影响。在提高下肢爆发力方面，左腿获得的最相关结果体现在单腿原地垂直跳测试中的跳跃高度参数中，而右腿则体现在以下测试中：往返跳和左右侧跳各 5 次。研究中最显著的进展是在测试中，按照其权重降序排列：双腿 60 秒垂直跳；往返跳和左右侧跳各 5 次，单腿站立垂直跳 5 次，BFS 垂直跳。
