Summary
Excessive dynamic genu valgum (DGV) upon landing may impair athletic performance by reducing quadriceps efficiency and stretch-shortening cycle function. Further research is needed to understand its impact on movement post-landing.
Area of Science:
- Biomechanics
- Sports Science
- Movement Analysis
Background:
- Dynamic genu valgum (DGV) is a common kinematic alteration during landing.
- Understanding DGV's impact on athletic performance is crucial for injury prevention and training optimization.
Purpose of the Study:
- To review the literature on the role of excessive dynamic genu valgum (DGV) upon landing in subsequent athletic movement performance.
- To explore the theoretical frameworks and influencing factors of DGV during landing.
Main Methods:
- A snowballing literature search was conducted across major scientific databases (PubMed, CINAHL, Wiley, ProQuest, Scopus) and Google Scholar.
- Relevant biomechanics and movement analysis textbooks were also consulted.
Main Results:
- Excessive medial knee excursion during landing may reduce quadriceps mechanical advantage and impair stretch-shortening cycle efficiency.
- Factors like stabilizer strength deficits, fatigue, and dual tasks can influence knee valgus during landing.
Conclusions:
- Excessive DGV upon landing is theorized to negatively impact subsequent athletic movement performance.
- Further research should investigate post-landing movement mechanics and the influence of trunk and subtalar joint kinematics in DGV.

An object's apparent weight is its weight measured by a spring balance at its location. It is different from its true weight, the force with which the Earth pulls it, because of the Earth's rotation. Mathematically, an object's apparent weight equals its true weight minus the centripetal force that keeps it in a circular motion along with the Earth's surface every 24 hours.
The difference between the true and apparent weights is proportional to the square of the Earth's angular speed. Since the...

01:17Factors Affecting Activity Coefficient
The extended Debye-Hückel equation indicates that the activity coefficient of an ion in an aqueous solution at 25°C depends on three partially interdependent properties: the ionic strength of the solution, the charge of the ion, and the ion size.
The activity coefficient value for an ion is close to one when the solution has almost zero ionic strength, i.e., when the solution shows close to ideal behavior. As the ionic strength of the solution increases from 0 to 0.1 mol/L, a decrease in the...
