Influence of stretch magnitude on the stretch-shortening cycle in skinned fibres [PDF]

Journal of Experimental Biology, 2019
The mechanical work attained during shortening is increased by prior stretching. Recently, we suggested that the residual force enhancement (RFE) may contribute to this enhanced work. RFE can be changed reliably by changing the stretch magnitude. Therefore, the purpose of this study was to examine the effect of stretch magnitude, and by association of ...

Blood RNA Biomarker Signatures for Early Diagnosis and Prognosis in Ischemic and Hemorrhagic Stroke: The IBIS‐CT1 Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To evaluate the expression of nine blood RNA biomarkers in a clinical trial based on genes previously identified in an experimental monkey model of stroke for diagnosis feasibility and prognostication. Methods IBIS‐CT1 was a prospective longitudinal study enrolling patients with ischemic stroke (IS) or intracerebral hemorrhage (ICH ...

A Workflow to Accelerate Microstructure‐Sensitive Fatigue Life Predictions

Advanced Engineering Materials, EarlyView.
This study introduces a workflow to accelerate predictions of microstructure‐sensitive fatigue life. Results from frameworks with varying levels of simplification are benchmarked against published reference results. The analysis reveals a trade‐off between accuracy and model complexity, offering researchers a practical guide for selecting the optimal ...

The stretch shortening cycle and the vertical jumping ability

Revista Paulista de Educação Física, 1998
O salto vertical é uma ação básica para várias modalidades esportivas, sendo que muitas pesquisas vêm sendo realizadas na tentativa de se estabelecer um referencial teórico para sua compreensão. Seu desenvolvimento se deu em grande parte pela importância que o salto vertical tem para o estudo do Ciclo « de Alongamento e Encurtamento (CAE), o qual é um ...

Effect of surface stiffness on the neural control of stretch‐shortening cycle movements [PDF]

Acta Physiologica, 2014
AbstractAimIt is accepted that leg stiffness (Kleg) increases when surface stiffness decreases, and vice versa. However, little is known how the central nervous system fulfils this task. To understand the effect of surface stiffness on the neural control of stretch‐shortening cycle movements, this study aimed to compare modulation of spinal and ...

Microstructure Modification of Additively Manufactured Mo–9Si–8B by Annealing and Its Effects on High‐Temperature Mechanical Properties

Advanced Engineering Materials, EarlyView.
Postbuild annealing systematically modifies the phase fractions and morphology of EB‐PBF processed Mo–9Si–8B. Quantitative microstructure–property correlations reveal how controlled phase evolution enhances high‐temperature compressive strength and creep resistance.

Acceleration Capacity and Vertical Jump Performance Relationship in Prepubertal Children

Applied Sciences
Sprint and jump abilities are considered basic skills that are regularly evaluated in training and school contexts. The correlations between these two skills have previously been established in adults and adolescents, but they have not been fully ...
