概括

拉克罗斯传球准确度随着速度的增加而下降,显示出方向偏差和技能差异. 变量沿运动轴集中,影响性能和训练重点.

科学领域:

电机控制和生物力学
体育科学和绩效分析

背景情况:

拉克罗斯传球对于比赛动态至关重要,但速度精度的权衡,特别是定向方面和技能变化,尚未完全理解.
现有的运动控制研究已经认识到速度与准确性之间的权衡,但它对拉克罗斯传球的具体应用需要进一步的研究.

研究的目的:

量化传球速度,准确性,偏差和拉克罗斯球中的一致性之间的关系.
检查熟练和不熟练的女性球员之间通过表现的方向效应和差异.

主要方法:

22名女大学 Lacrosse 球员在不同的努力条件下进行过手传球.
记录了球的速度和着陆坐标,使用辐射误差 (RE),心点误差 (CE) 和双变量误差 (BVE) 分析了准确度,偏差和一致性.
通过错误圆分析评估方向模式,并使用双向ANOVA分析数据.

主要成果:

球的速度随着努力显著增加,传球误差 (RE, , BVE) 随着速度的增加而增加,表明沿主要轴的方向依赖与变化.
熟练的玩家表现出较低的RE和BVE,特别是在垂直和主要轴组件中,表明更高的准确性和一致性.

First Pass Effect

First Pass Effect

Presystemic elimination, or the first-pass effect, is the metabolism of drugs that reduces their effective concentration at the site of action. Apart from the first-pass effect, the systemic bioavailability of the drug is also reduced by other factors, including incomplete absorption or chemical degradation of drugs.
Depending on the route of administration, drugs can be metabolized in the liver, intestine, lungs, and vasculature. Orally administered drugs are first absorbed through the...

Improving Translational Accuracy

Improving Translational Accuracy

Base complementarity between the three base pairs of mRNA codon and the tRNA anticodon is not a failsafe mechanism. Inaccuracies can range from a single mismatch to no correct base pairing at all. The free energy difference between the correct and nearly correct base pairs can be as small as 3 kcal/ mol. With complementarity being the only proofreading step, the estimated error frequency would be one wrong amino acid in every 100 amino acids incorporated. However, error frequencies observed in...

Uncertainty in Measurement: Accuracy and Precision

Uncertainty in Measurement: Accuracy and Precision

Scientists typically make repeated measurements of a quantity to ensure the quality of their findings and to evaluate both the precision and the accuracy of their results. Measurements are said to be precise if they yield very similar results when repeated in the same manner. A measurement is considered accurate if it yields a result that is very close to the true or the accepted value. Precise values agree with each other; accurate values agree with a true value.

Single-pass Transmembrane Proteins

Single-pass Transmembrane Proteins

Integral membrane proteins are tightly associated with the cell membrane and play a crucial role in cell communication, signaling, adhesion, and transport of the molecules. Some integral membrane proteins are present only in the membrane monolayer. For example, the enzyme fatty acid amide hydrolase is present in the cytoplasmic side of the membrane monolayer. In contrast, another type of integral membrane protein, also known as a transmembrane protein, spans across the membrane. Transmembrane...
