Pontryagin's maximum principle and optimization of the flight phase in ski jumping [Pontrjaginův princip maxima a optimalizace stylu letu ve skoku na lyžích]

open access: yesActa Universitatis Palackianae Olomucensis. Gymnica, 2009
BACKGROUND: There are several factors (the initial ski jumper's body position and its changes at the transition to the flight phase, the magnitude and the direction of the velocity vector of the jumper's center of mass, the magnitude of the aerodynamic ...

Intramuscular pathways of maladaptation in overtraining syndrome

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend The transition from adaptive overreaching to maladaptive overtraining and mechanisms through which excessive training load can lead to performance decline. Four interconnected pathophysiological domains are highlighted: neural fatigue, involving both central and peripheral components such as altered sensory feedback and reflex ...

Powder to the People: Exploring the User Experience and Ski Area Design Elements of the Hankin-Evelyn Backcountry Ski Area

open access: yes, 2012
North America’s first officially designated backcountry ski area, the Hankin-Evelyn Backcountry Ski Area (Hankin) in northern British Columbia, offers mountain communities seeking alternative recreational amenities an interesting model to emulate. The aim of the research is to explore backcountry ski area design by assessing the quality of both the ski

Mechanisms of haemoglobin mass expansion following heat stress

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Theorised mechanisms of heat stress‐induced erythropoiesis which may facilitate the expansion of haemoglobin mass. A, acute: heat stress‐induced renal ischaemia. Redistribution of blood flow away from the kidneys to facilitate thermoregulation during heat stress could reduce renal oxygen delivery, subsequently lowering renal PO2${

Assessment of avalanche hazard of freeride skiing areas

open access: yes
Abstract. Freeride skiing and ski touring have been growing in popularity in Slovakia as an alternative to crowded ski slopes, offering skiers the thrill of untracked snow and challenging terrain. However, venturing into unmanaged mountain areas exposes participants to significantly greater dangers, especially avalanches and risk of falling. This study

Determinants of maximal oxygen uptake in highly trained females and males: a mechanistic study of sex differences using advanced invasive methods

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend The results from this study show that maximal cardiac output, stroke volume and leg blood flow are similar between highly trained females and males after normalisation to lean body mass (LBM). However, the 10% higher haemoglobin concentration ([Hb]) and arterial O2 content in males result in higher systemic and leg O2 delivery ...
