概括
一个手机应用程序精确地测量了女排球员的反运动跳跃高度, 然而,在使用这些工具来评估CMJ平均功率时,建议谨慎使用.
科学领域:
- 运动科学
- 生物力学
- 绩效分析
背景情况:
- 准确测量跳跃表现对于训练和体育人才的识别至关重要.
- 基于现场的设备提供了方便,但与标准措施相比,它们的有效性需要彻底调查.
- 女排球员需要精确地评估爆炸力,特别是反运动跳跃 (CMJ).
研究的目的:
- 评估三种基于现场的设备 (跳跃和达到设备,线性位置传感器,手机应用程序) 的测量反运动跳跃 (CMJ) 性能.
- 将这些装置的有效性与精英女排球员的标准力板系统进行比较.
主要方法:
- 16名女子排球运动员进行了反运动跳跃 (CMJs).
- 跳跃性能同时使用强力板 (标准),跳跃和伸缩装置,线性位置传感器和手机应用程序进行记录.
- 数据分析侧重于CMJ高度和平均功率,将现场设备的测量与力板数据进行比较.
主要成果:
- 移动电话应用程序 (APP) 显示了CMJ高度的最高准确性,与力板 (FP) 相比,显示了最强的相关性 (r=0.99) 和最小的误差.
- 通过APP测量的CMJ高度 (35.32±3.75厘米) 与FP (36.16±3.88厘米) 相似,而跳跃和达到装置和线性位置传感器显示了显著的高估值.
- 现场装置对CMJ平均功率表现出相当大的误差和很大的一致性,这表明与跳跃高度相比,该指标的有效性较低.
结论:
- 移动电话应用程序是一个有效的工具来评估女排球员的反运动跳跃高度.
- 现场设备和标准力板之间的平均功率测量存在显著差异.
- 运动员和教练在解释来自现场测量工具的CMJ平均功率数据时应谨慎.

Direct Method
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...

Electronic Distance Measuring Instruments (EDMs) are essential tools in modern surveying, offering precise distance measurements by emitting electromagnetic signals and calculating the time required for these signals to travel to a target and return. Two primary types of signals are used in EDMs — light waves and microwaves — each suited to specific environmental and distance requirements. Light-wave-based EDMs utilize either infrared or laser light, providing high accuracy over...
