Isotonic and Isometric Muscle Contractions01:22

Isotonic and Isometric Muscle Contractions

3.2K
Two primary types of muscle contractions are isotonic and isometric, each serving unique functions and involving distinct mechanisms. Both isotonic and isometric contractions are integral to the body's complex system of movement and stability. Isotonic exercises contribute significantly to functional strength and movement, while isometric contractions are crucial for maintaining posture and joint stability.

Isotonic contractions occur when a muscle changes length while...

Non-destructive Tests for Concrete Strength01:12

Non-destructive Tests for Concrete Strength

117
The rebound hammer test, also known as the Schmidt hammer test, is a non-destructive technique for evaluating the hardness of concrete and, indirectly, the strength of concrete. It operates on the principle that the rebound of a spring-driven mass from a concrete surface correlates to the surface's hardness. The device comprises a mass within a tubular housing, a spring mechanism, and a plunger that strikes the concrete. Upon release, the energy imparted to the mass by the spring causes it...

  • 由于可比性问题,临床应用需要设备特定的参考值.
  • 关于不同强度测试设备之间的功能比率可比性的文献有限.

研究的目的:

  • 为两个强度诊断系统 (Myoline和Frei) 确定干部和膝盖曲/延伸的参考值.
  • 分析这些系统及其功能比率的可复制性和相反的可比性.
  • 为临床强度测试提供特定设备的基准.

主要方法:

  • 对98名健康成年人进行横截面研究,评估干部和膝盖的曲/延伸.
  • 使用Myoline和Frei医疗系统进行同度强度测试.
  • 在子样本上分析了可靠性 (ICC3.1,SEM,VK%) 和解释的差异 (r2).

主要成果:

  • 米奥林和弗雷系统都显示出高可靠性 (ICC3.1 0.76-0.95).
  • 功能比率显示出更低的可靠性 (ICC3.1 0.62-0.92).
  • 峰值力量的相互解释差异为19-68%,功能比为5-21%.

结论:

  • 这两种设备的强度测试值和功能比值不能直接比较.
  • 每个设备都是强度测试的可靠工具.
  • 在临床环境中可以使用特定于设备的,根据体重调整的基准值.
