Experimental Physiology, EarlyView.Abstract Ski mountaineering (SkiMo) is a new Olympic sport with extreme endurance demands and altitude exposure. Previous studies have focused on traditional cardiorespiratory variables, such as maximal oxygen consumption (V̇O2max${\dot V_{{{\mathrm{O}}_{\mathrm{2}}}{\mathrm{max}}}}$) or ventilatory thresholds, but, to our knowledge, did not report ...

Optimizing Cycle Exercise Performance During Normobaric Hypoxia Exposure
, 2019 Introduction: The purpose of the present study was to examine whether implementing factors of OPTIMAL Theory: Enhanced Expectancies (EE), Autonomy Support (AS), and External Focus (EF) during a cycle exercise bout at a simulated altitude of 21,000 feet ...

Influence of facial cooling on carotid body tonic activity and sensitivity
Experimental Physiology, EarlyView.Abstract Facial cooling can increase ventilation and augment the hypoxic ventilatory response. Whole body cooling increases both carotid body tonic activity and sensitivity; however, whether isolated facial cooling induces similar carotid body hyperexcitability was unknown.

Tracking performance with two breathing oxygen concentrations after high altitude rapid decompression [PDF]
Current military aircraft Liquid Oxygen (LOX) systems supply 99.5 pct. gaseous Aviator's Breathing Oxygen (ABO) to aircrew. Newer Molecular Sieve Oxygen Generation Systems (MSOGS) supply breathing gas concentration of 93 to 95 pct. O2.

Experimental Physiology, EarlyView.Abstract We examined the impact of moderate hypoxia (HYPO) on muscle activation during incremental exercise matched for both absolute and equivalent relative intensity. Fifteen active subjects (10 males, 5 females) completed two ramp incremental test and two step tests in normoxia (NORM; FiO2${F_{{\mathrm{i}}{{\mathrm{O}}_2}}}$ = 0.209) and HYPO (FiO2${

Cardiovascular, respiratory and splenic responses to rebreathing and apnoea during exercise
Experimental Physiology, EarlyView.Abstract We investigated integrative physiological responses to eupnoeic exercise (EX), rebreathing exercise (RB), dynamic apnoea (DA) and dynamic apnoea with cold‐water face immersion (DAFI) in 20 healthy participants. Trials involved non‐steady‐state cycle exercise at 60 W for an average duration of 66 s.

THE IMPACT OF PENILE CANCER TREATMENT ON SEXUAL RELATIONSHIPS: A QUALITATIVE ENQUIRY [PDF]
, 2012 Background: Penile cancer is a rare but highly treatable condition. Current guidance recommends the use of a surgical procedure to excise the primary tumour (and a margin of normal penile tissue).
