概括
在自由重量 (FW) 坐期间,线性位置传感器的放置显示了基于速度的训练中条杆和皮带附件之间的强烈一致. 这种方法,以及史密斯机器棒的放置,与训练有素的女性的跳跃性能有很好的相关性.
科学领域:
- 生物力学和运动生理学
- 体育科学与绩效分析 运动科学与绩效分析
背景情况:
- 研究了线性位置传感器 (LPT) 放置 (杆与皮带) 在训练有素的女性中,在史密斯机 (SM) 和自由重量 (FW) 坐时,对平均速度和负载速度关系的影响.
- 评估了负载速度特征和跳跃性能之间的相关性,以确定训练有效性的最佳测试方法.
研究的目的:
- 为了比较不同的LPT放置和式变化 (SM与FW) 之间的平均速度和负载速度参数.
- 为了确定载荷速度数据和爆炸性性能指标 (跳跃测试) 之间的关系.
- 建立最合适的测试方法,以速度为基础的训练和表现监测在训练有素的女运动员.
主要方法:
- 11名受过训练的女性进行了FW和SM全背坐的1重复最大 (1-RM) 评估.
- 在FW和SM坐时,LPT被附在杆 (BAR) 和皮带 (BELT) 上.
- 测量了30-100%的1-RM负载的平均速度;使用线性回归分析了负载-速度关系. 使用光学系统测量跳跃性能 (腰,反移动,跌落跳跃).
主要成果:
- 1-RM在MS中明显高于FW坐.与FW坐相比.
- 在FW BAR和FW BELT之间发现了强大的协议 (Lin的CCC=0.96-0.99),在SM BAR和FW BAR之间发现了30-70%的1-RM,这表明可互换性.
- SM BELT 系统地显示较低的平均速度和与其他条件差的一致性. 在低至中等负载 (30-70% 1-RM) 的平均速度与跳跃性能有很强的相关性 (r = 0.63-0.93),特别是在SM BAR和FW BELT条件下. 相对强度仅在FW条件下与跳跃性能相关.
结论:
- 在受过训练的女性中,FW BAR和FW BELT LPT安置可以互换为以速度为基础的训练,在亚最大负载下进行训练.
- SM BELT放置导致平均速度较低和一致性较差,因此不太适合基于速度的训练比较.
- 低至中等负载的平均速度有效地预测下部机身爆炸性能,有助于个性化的训练和监控.

Energy Losses in Transformers
In an ideal transformer, it is assumed that there are no energy losses, and, hence, all the power at the primary winding is transferred to the secondary winding. However, in reality, the transformers always have some energy losses, and, hence, the output power obtained at the secondary winding is less than the input power at the primary winding due to energy losses.
There are four main reasons for energy losses in transformers.
The first cause can be the high resistance of the copper windings...

Mechanical Efficiency of Real Machines
The mechanical efficiency of a machine is a fundamental concept that describes how effectively a machine can convert input work into output work. According to this concept, the efficiency of a machine is equal to the ratio of the output work to the input work. An ideal machine, meaning a machine that has no energy losses, has an efficiency of one. This implies that the input work and the output work are equal.
However, in reality, no machine can be truly ideal, and all of them experience some...

Distributed Loads
Distributed loads are a common type of load that engineers and scientists encounter in various practical situations. Distributed loads often refer to a type of load spread over a surface or a structure and can be modeled as continuous force per unit area.
For example, consider a bookshelf filled with books stacked vertically adjacent to each other. The weight of the books is evenly distributed over the length of the shelf. As a result, the pressure at different locations on the surface of the...

The Ideal Transformer
In single-phase two-winding transformers, two windings are coiled around a magnetic core characterized by cross-sectional area A and magnetic permeability μ. A phasor current i1 enters the left winding while i2 exits the right winding, establishing the fundamental working of the transformer through electromagnetic principles.
Ampere's Law forms the basis of understanding the magnetic field within the transformer. It states that the integral of the magnetic field intensity's tangential component...

Transformers in Distribution System
Transformers in distribution systems can be broadly categorized into distribution substation transformers and other distribution transformers. They are crucial for stepping down high transmission voltages to levels suitable for distribution and end-user applications.
Distribution substation transformers come in various ratings and typically use mineral oil for insulation and cooling. To prevent moisture and air from entering the oil, some transformers use an inert gas like nitrogen to fill the...

Simplified Synchronous Machine Model
The Synchronous Machine Model is a fundamental tool in analyzing and ensuring the transient stability of power systems. This model simplifies the representation of a synchronous machine under balanced three-phase positive-sequence conditions, assuming constant excitation and ignoring losses and saturation. The model is pivotal for understanding the behavior of synchronous generators connected to a power grid, particularly during transient events.
In this model, each generator is connected to a...
