The use of inertial and physiological sensors in a sport such as judo is scarce to date. The information provided by these sensors would allow practitioners to have a better understanding of sports performance, which is necessary for an accurate training prescription. The purpose of this study was to use inertial and physiological sensors in order to investigate the effect of a plyometric and high-intensity interval training (HIIT) training program on Special Judo Fitness Test (SJFT) performance and speed of execution of throws in young judokas. A total of 32 participants were divided into two groups: experimental and control. The intervention consisted of six sessions with a duration of 60 min for 3 weeks. Physiological sensors collected heart rate data to assess the Special Judo Fitness Test, and inertial sensors collected angular velocity. The results show a significant decrease in the SJFT index (Score pre: 22.27 ± 2.73; Score post: 19.65 ± 1.70; ≤ 0.05; = 0.61) and a significant increase in the angular velocity of the -axis (Pre: 320.87 ± 51.15°/s; Post: 356.50 ± 40.47°/s; ≤ 0.05; = 0.45) and -axis (Pre: 259.40 ± 41.99°/s; Post: 288.02 ± 65.12°/s; ≤ 0.05; = 0.31) in the experimental group. In conclusion, this study demonstrates that using inertial and physiological sensors allowed us to analyze the effect that a high-intensity interval training program and plyometrics had on the performance of young judokas. Strength and conditioning coaches should consider these results because including plyometric training and HIIT in judokas' workout programming can be especially positive for eliciting increases in performance. However, future training interventions should investigate the training adaptations to longer interventions.
在柔道等运动中，惯性和生理传感器的使用至今仍很少见。这些传感器提供的信息将使从业者更好地了解运动表现，这对于准确的训练处方是必要的。本研究的目的是使用惯性和生理传感器来研究一种增强式和高强度间歇训练（HIIT）训练计划对年轻柔道运动员特殊柔道体能测试（SJFT）表现和投掷执行速度的影响。共有 32 名参与者被分为两组：实验组和对照组。干预措施包括 6 次，每次 60 分钟，持续 3 周。生理传感器收集心率数据来评估特殊柔道体能测试，而惯性传感器收集角速度。结果显示 SJFT 指数显著下降（得分前：22.27 ± 2.73；得分后：19.65 ± 1.70； ≤ 0.05； = 0.61），而 -轴的角速度显著增加（前：320.87 ± 51.15°/s；后：356.50 ± 40.47°/s； ≤ 0.05； = 0.45）和 -轴（前：259.40 ± 41.99°/s；后：288.02 ± 65.12°/s； ≤ 0.05； = 0.31）在实验组中。总之，本研究表明，使用惯性和生理传感器使我们能够分析高强度间歇训练计划和增强式训练对年轻柔道运动员表现的影响。力量和体能教练应该考虑这些结果，因为在柔道运动员的训练计划中加入增强式训练和 HIIT 可以特别有助于提高表现。然而，未来的训练干预措施应该研究更长时间干预的训练适应。
