The Effects of Selected Mechanical and Anthropometric Variables on Change-of-Direction Ability in National Team-Level Youth Basketball Players [PDF]
SportsChange-of-direction (COD) ability is a key determinant of performance in youth basketball, yet the relative contribution of braking, re-acceleration, trunk motion, and body composition remains unclear.

Profiling Change of Direction Ability Using Sub-phase 5-0-5 Analysis
International Journal of Strength and Conditioning, 2022 Change of direction (COD) ability is an important component for most field and court sport athletes. The modified 5-0-5 COD test is a commonly used test to measure 180-degree COD performance, the diagnostic value of which can be advanced using a ...

Effects of different maturity status on change of direction performance of youth tennis players
Biology of Sport, 2022 The aim of this study was to examine the maturational status (i.e., peak height velocity [PHV]) differences in neuromuscular performance (i.e., vertical jump, linear sprint, change of direction (COD) using different tests, and change of direction deficit

Direct and Indirect Effects Based on Changes-in-Changes [PDF]
SSRN Electronic Journal, 2019 We propose a novel approach for causal mediation analysis based on changes-in-changes assumptions restricting unobserved heterogeneity over time. This allows disentangling the causal effect of a binary treatment on a continuous outcome into an indirect effect operating through a binary intermediate variable (called mediator) and a direct effect running

Change of Direction in the Biomechanics of Atherosclerosis [PDF]
Annals of Biomedical Engineering, 2014 The non-uniform distribution of atherosclerosis within the arterial system has been attributed to pro-atherogenic influences of low, oscillatory haemodynamic wall shear stress (WSS) on endothelial cells (EC). This theory is challenged by the changes in lesion location that occur with age in human and rabbit aortas.

The Environment and Directed Technical Change [PDF]
SSRN Electronic Journal, 2009 This paper introduces endogenous and directed technical change in a growth model with environmental constraints. The final good is produced from “dirty” and “clean” inputs. We show that: (i) when inputs are sufficiently substitutable, sustainable growth can be achieved with temporary taxes/subsidies that redirect innovation toward clean inputs; (ii ...
