Linear and Nonlinear Prediction Models Show Comparable Precision for Maximal Mean Speed in a 4x1000 m Field Test

International Journal of Computer Science in Sport, 2017
Maximal oxygen uptake (VO2max) is one of the most distinguished parameters in endurance sports and plays an important role, for instance, in predicting endurance performance.

The Maximal Oxygen Uptake Verification Phase: a Light at the End of the Tunnel? [PDF]

Sports Medicine - Open, 2017
Commonly performed during an incremental test to exhaustion, maximal oxygen uptake (V̇O2max) assessment has become a recurring practice in clinical and experimental settings. To validate the test, several criteria were proposed. In this context, the plateau in oxygen uptake (V̇O2) is inconsistent in its frequency, reducing its usefulness as a robust ...

Variable Stiffness Flexure Structures Enabled by Phase‐Change Gallium and Adhesive Interfacial Locking for Soft Robotic Applications

Advanced Engineering Materials, EarlyView.
A flexure‐based variable stiffness structure is developed by integrating phase‐change modulation and adhesive interfacial locking of gallium. The design enables a wide stiffness variability, transitioning from soft, flexible behavior to rigid, load‐supporting performance.

Effects of downhill walking training on aerobic and neuromuscular fitness of young adults

Revista Brasileira de Cineantropometria e Desempenho Humano, 2015
Eccentric exercise training using low intensity-high volume approach has been performed to improve maximal muscle strength and power. The aim of this study was to compare the effects of short-term downhill walking and level walking training on lower limb

Determinants of maximal oxygen uptake in severe acute hypoxia [PDF]

American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 2003
To unravel the mechanisms by which maximal oxygen uptake (V˙o 2 max) is reduced with severe acute hypoxia in humans, nine Danish lowlanders performed incremental cycle ergometer exercise to exhaustion, while breathing room air (normoxia) or 10.5% O2 in N2(hypoxia, ∼5,300 m above sea level).

High‐Temperature Nanoindentation of Metals: Assessing Thermal Drift, Frame Compliance, and Chemical Composition Effects on the Reported Mechanical Properties

Advanced Engineering Materials, EarlyView.
Do not let thermal drift and instrument artifacts deceive high‐temperature nanoindentation results. We compare classical Oliver–Pharr and automatic image recognition analyses across steels and a Ni alloy to quantify these effects. Accounting for artifacts reveals systematic softening with temperature, while Cr and Ni additions boost resistance ...

Recycling of NiTi Shape Memory Alloys: Fundamental and Technological Aspects of a Vacuum Induction Melting Processing Route

Advanced Engineering Materials, EarlyView.
The present study investigates recycling of NiTi shape memory alloys via vacuum induction melting. An ingot was synthesized from elemental Ni and Ti and subjected to three subsequent remelting cycles. Remelting increases process durations and impurity levels and adversely affects microstructures and functional properties.

10. OXIDATIVE STRESS AND ARTERIAL STIFFNESS IN STRENGTH- AND ENDURANCE-TRAINED ATHLETES

Artery Research, 2009
Background: Endurance exercise training decreases arterial stiffness, whereas high-intensity strength exercise training increases arterial stiffness. However, the mechanisms underlying the different adaptations to these two types of exercise training are
