The aims of this study were to examine energy conversion strategies during 100 m sprinting and to determine whether there are opportunities for performance enhancement beyond the usual 'maximum effort throughout' strategy. The roles of aerodynamic drag and kinetic energy recovery on the overall whole-body energy balance are discussed. A mathematical model based on sprinting with maximum effort,...

Scientific collaboration is a popular issue in the literature on knowledge production. Although previous studies show that scientific teamwork becomes dominant and is related to the impact of scientific results, empirical results of this research reveal that collaboration itself is not “the almighty” for quality research. This study finds the following three stylized facts. First, Korean univer...

PURPOSE: This study examined the effect of anticipatory control strategies on stable upright posture and consistency in archery performance among skilled elite archers.METHODS: Nine players participated this performed repeated shooting trials under two different conditions: clicker non-clicker. In condition, archers shot response to signals, whereas non-clicker they used an strategy determine t...

We investigated differences of the spatiotemporal parameters in a 100-m sprint among elite, sub-elite, and non-elite sprinters with a unilateral transtibial amputation. Using publicly available Internet broadcasts, we analyzed 125, 19, and 33 records from 30 elite, 12 sub-elite, and 22 non-elite sprinters, respectively. Average speed, step frequency, and step length were calculated Average spee...

After the Covid-19 outbreak, emergence of an economic recession is impact various policies to prevent spread virus, such as extreme lockdown policy Large-Scale Social Restrictions. Sampang, a small regency in Madura Island, Indonesia, has successfully maintained low case Covid-19. This article elaborates on success Sampang Regency maintaining its green zone status. More specifically, what gover...

A hybrid pulse width modulation (PWM) theme for the grid electrical converter is investigated, which combines the deserves of space-vector PWM (SVM) and elite harmonic elimination PWM (SHEPWM). SHEPWM is adopted at steady state, while SVM is adopted to reach higher dynamic performance at grid fault. A transition strategy between these two PWM schemes is projected, which achieves sleek and fast ...

OBJECTIVE Motor control of the muscles of the face, lips, and tongue of horn players has traditionally been described from externally observed phenomena. Developments in real-time, high-speed magnetic resonance imaging (MRI) extend the scope of study to include descriptive and quantitative information from within the mouth. We employed these developments to compare oral movement strategies betw...
