Optimal slopes and speeds in uphill ski mountaineering: a laboratory study

Kamiar Aminian, Benedikt Fasel, Philippe Vuistiner

Purpose: The purpose of this study was to estimate the energy cost of linear (EC) and vertical displacement (ECvert), mechanical efficiency and main stride parameters during simulated ski mountaineering at different speeds and gradients, to identify an opt ...

Glycogen metabolism and the homeostatic regulation of sleep

Pierre Magistretti, Igor Allaman, Jean-Marie Petit, Sophie Burlet Godinot

In 1995 Benington and Heller formulated an energy hypothesis of sleep centered on a key role of glycogen. It was postulated that a major function of sleep is to replenish glycogen stores in the brain that have been depleted during wakefulness which is asso ...

Sustained Sleep Fragmentation Induces Sleep Homeostasis in Mice

Pierre Magistretti, Jean-Marie Petit, Maxime Olivier Baud

Study Objectives: Sleep fragmentation (SF) is an integral feature of sleep apnea and other prevalent sleep disorders. Although the effect of repetitive arousals on cognitive performance is well documented, the effects of long-term SF on electroencephalogra ...

Estimation of Front-Crawl Energy Expenditure Using Wearable Inertial Measurement Units

Kamiar Aminian, Grégoire Millet, Farzin Dadashi

Measurement of the energy expenditure is crucial to understand the biophysics of any kind of human locomotion. Despite the promising application of inertial measurement unit (IMU) for quantification of the energy expenditure during human on-land activities ...

Ieee2013

Age-related disturbances of the sleep-wake cycle can reflect ontogenetic changes in regulatory mechanisms underlying normal and pathological aging, but the exact nature of these changes remains unclear. The present report is the first attempt to apply prin ...

Evidence that the Lunar Cycle Influences Human Sleep

Endogenous rhythms of circalunar periodicity (similar to 29.5 days) and their underlying molecular and genetic basis have been demonstrated in a number of marine species [1, 2]. In contrast, there is a great deal of folklore but no consistent association o ...

Genes Involved in the Astrocyte-Neuron Lactate Shuttle (ANLS) Are Specifically Regulated in Cortical Astrocytes Following Sleep Deprivation in Mice

Pierre Magistretti, Jean-Luc Martin, Jean-Marie Petit, Joël Gyger, Sophie Burlet Godinot

Study Objectives: There is growing evidence indicating that in order to meet the neuronal energy demands, astrocytes provide lactate as an energy substrate for neurons through a mechanism called "astrocyte-neuron lactate shuttle" (ANLS). Since neuronal act ...
