Time-domain and frequency-domain effects of tensor tympani contraction on middle ear sound transmission in gerbil.

Liam Gallagher, Mohamed Diop, Elizabeth S Olson,

The middle ear is a high-fidelity, broadband impedance transformer that transmits acoustic stimuli at the eardrum to the inner ear. It is home to the two smallest muscles in mammalian species, which modulate middle ear transmission. Of this pair, the function of the tensor tympani muscle (TTM) has remained obscure. ...

Fuel Use during Exercise at Altitude in Women with Glucose-Fructose Ingestion.

John P O'Hara, Lauren Duckworth, Alistair Black, David R Woods, Adrian Mellor, Christopher Boos, Liam Gallagher, Costas Tsakirides, Nicola C Arjomandkhah, Douglas J Morrison, Thomas Preston, Roderick F G J King,

<h4>Purpose</h4>This study compared the coingestion of glucose and fructose on exogenous and endogenous substrate oxidation during prolonged exercise at terrestrial high altitude (HA) versus sea level, in women.<h4>Method</h4>Five women completed two bouts of cycling at the same relative workload (55% Wmax) for 120 min on acute exposure to HA (3375 ...

Changes in balance and joint position sense during a 12-day high altitude trek: The British Services Dhaulagiri medical research expedition.

Sarah B Clarke, Kevin Deighton, Caroline Newman, Gareth Nicholson, Liam Gallagher, Christopher J Boos, Adrian Mellor, David R Woods, John P O'Hara,

Postural control and joint position sense are essential for safely undertaking leisure and professional activities, particularly at high altitude. We tested whether exposure to a 12-day trek with a gradual ascent to high altitude impairs postural control and joint position sense. This was a repeated measures observational study of 12 ...

Markers of physiological stress during exercise under conditions of normoxia, normobaric hypoxia, hypobaric hypoxia, and genuine high altitude.

David Richard Woods, John Paul O'Hara, Christopher John Boos, Peter David Hodkinson, Costas Tsakirides, Neil Edward Hill, Darren Jose, Amanda Hawkins, Kelly Phillipson, Antonia Hazlerigg, Nicola Arjomandkhah, Liam Gallagher, David Holdsworth, Mark Cooke, Nicholas Donald Charles Green, Adrian Mellor,

<h4>Purpose</h4>To investigate whether there is a differential response at rest and following exercise to conditions of genuine high altitude (GHA), normobaric hypoxia (NH), hypobaric hypoxia (HH), and normobaric normoxia (NN).<h4>Method</h4>Markers of sympathoadrenal and adrenocortical function [plasma normetanephrine (PNORMET), metanephrine (PMET), cortisol], myocardial injury [highly sensitive cardiac troponin T (hscTnT)], and ...

A comparison of substrate oxidation during prolonged exercise in men at terrestrial altitude and normobaric normoxia following the coingestion of 13C glucose and 13C fructose.

John P O'Hara, David R Woods, Adrian Mellor, Christopher Boos, Liam Gallagher, Costas Tsakirides, Nicola C Arjomandkhah, David A Holdsworth, Carlton B Cooke, Douglas J Morrison, Thomas Preston, Roderick Fgj King,

This study compared the effects of coingesting glucose and fructose on exogenous and endogenous substrate oxidation during prolonged exercise at altitude and sea level, in men. Seven male British military personnel completed two bouts of cycling at the same relative workload (55% W<sub>max</sub>) for 120 min on acute exposure to altitude ... Read more >>

A Four-Way Comparison of Cardiac Function with Normobaric Normoxia, Normobaric Hypoxia, Hypobaric Hypoxia and Genuine High Altitude.

Christopher John Boos, John Paul O'Hara, Adrian Mellor, Peter David Hodkinson, Costas Tsakirides, Nicola Reeve, Liam Gallagher, Nicholas Donald Charles Green, David Richard Woods,

<h4>Background</h4>There has been considerable debate as to whether different modalities of simulated hypoxia induce similar cardiac responses.<h4>Materials and methods</h4>This was a prospective observational study of 14 healthy subjects aged 22-35 years. Echocardiography was performed at rest and at 15 and 120 minutes following two hours exercise under normobaric normoxia (NN) ... Read more >>
