The cold‐water immersion recovery–adaptation paradox: Reconciling acute parasympathetic and analgesic benefits with chronic hypertrophy attenuation

Experimental Physiology, EarlyView.
Abstract Cold‐water immersion (CWI) is among the most widely used post‐exercise recovery modalities in elite sport and clinical rehabilitation, yet a fundamental paradox now emerges from the evidence: the same protocols that accelerate parasympathetic reactivation and reduce perceived muscle soreness also suppress the molecular and cellular machinery ...

Experimental Rotor Unbalance Response Using Hydrostatic Gas Lubrication

, 1973
This paper investigates the adequacy of the theoretical model in predicting the unbalance response of a rotor supported in hydrostatic gas-lubricated journal bearings.

Comparison of exercise training and repeated hot water immersion on vascular function in overweight older adults

Experimental Physiology, EarlyView.
Abstract Recent studies suggest that heat exposure may benefit cardiovascular health, but in overweight and obese older adults, the chronic effects of heat therapy on artery function are still uncertain. We aimed to compare the effects of 12 weeks (3×/week, 40 min) of aerobic exercise (EXE) to hot water immersion (HWI) and an inactive control group ...

A 45 min bout of hot‐water immersion induces transient plasma volume contraction without a detectable increase in circulating erythropoietin

Experimental Physiology, EarlyView.
Abstract Heat acclimation is increasingly used to induce haematological adaptations and enhance endurance performance. Although repeated hot‐water immersion (HWI) has been shown to increase haemoglobin mass, the acute physiological responses that might underpin these longer‐term adaptations remain poorly understood.

Human placental transfer of xenobiotics in health and disease: New approach methodologies for developmental and reproductive toxicology testing and mathematical modelling

The Journal of Physiology, EarlyView.
Abstract figure legend New approach methodologies (NAMs) to test the pharmaco‐ and chemicokinetics of compound transfer across the human placental barrier in late pregnancy. Abstract This review addresses an important and timely topic at the intersection of placental biology with respect to barrier transfer kinetics, toxicology and mathematical ...

Design of hydrostatic bearing for theater turntable

, 2021
This thesis deals with the issue of hydrostatic bearings. The aim was to design a test rig for an axial hydrostatic bearing. The axial hydrostatic bearing was calculated and designed with respect to the function of the tester.

Vibration Analysis of Hydrostatic Gas Bearing Spindle Considering the Elastic Deformation of Rotor.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1996
In this study, we present the vibration analysis procedure of a hydrostatic gas bearing spindle considering the stiffness and damping of a gas film and the effect of elastic deformation of the components of a rotor. An equation of motion for the elastic vibration of the rotor is formulated using the finite element method and then combined with the ...

Gas exchange and pulmonary stress variations during SCUBA and breath‐hold diving in open seawater

The Journal of Physiology, EarlyView.
Abstract figure legend Healthy, trained divers were studied before, during and after diving in open seawater with different techniques. SCUBA divers (diving to 15 or 40 m with air; cycling at depth) and breath‐hold divers (BHDs; sled‐assisted dives to 15, 25 or 40 m) underwent underwater and surface arterial blood gas (ABG) sampling.

Mechanisms reducing parasympathetic activity in chronic hypoxia

The Journal of Physiology, EarlyView.
Abstract figure legend Parasympathetic activity is reduced in chronic hypoxia, but the underlying mechanism(s) are unclear. Using β‐adrenergic blockade to isolate parasympathetic control of heart rate at sea level and after 9‐12 days at high altitude, we investigated whether (i) chemoreflex activation, (ii) increased pulmonary ventilation and/or (iii ...

A Self-Starting Hydrodynamic Gas Bearing

, 1972
An experimental self-starting hydrodynamic gas bearing was designed, built, and tested. This bearing operates on the principle that the bearing is started and stopped hydrostatically by means of an air supply which is generated by the bearing itself. For
