Sleep quality in athletes under normobaric hypoxia equivalent to 1500 m altitude: A polysomnographic study     

《European Journal of Sport Science》2013,13(3):191-198

Abstract

In the present study, we evaluated the duration of slow-wave sleep (Stage 3 and 4) and total delta power (< 3Hz) in all-night non-rapid eye movement (NREM) sleep electroencephalograms (EEGs) of athletes during normobaric hypoxia at simulated altitudes of 1500 m. Seven male athletes slept for two nights in a normoxic condition and one night in an hypoxic condition equivalent to an altitude of 1500 m. Whole-night polysomnographic recordings, thoracic and abdominal motion, nasal and oral airflow, and blood oxygen saturation (SpO₂) were recorded. Visual sleep stage scoring and fast Fourier transformation analyses of EEG were performed using 30-s epochs. Mean and minimum SpO₂ decreased significantly during sleep in the hypoxic condition. Between groups, changes in heart rate, respiratory disturbance measures including apnoea and hypopnoea, slow-wave sleep and total delta power of the all-night NREM sleep EEG were small and non-significant for the hypoxic condition_. However, individual difference in time at an SpO₂ below 90% were large in the hypoxic condition, and both slow-wave sleep and total delta power of all-night NREM sleep EEG decreased in three participants who spent a prolonged time below 90% SpO₂. The present results suggest that monitoring time below 90% SpO₂ is recommended when studying individuals' living-high schedule even under hypoxic conditions equivalent to an altitude of 1500 m.  相似文献

“Fear God; Fear the Bogaze”: The Nile Mouths and the Navigational Landscape of the Medieval Nile Delta,Egypt     

John P. Cooper 《Al-Masaq: Islam & the Medieval Mediterranean》2012,24(1):53-73

By the fourth/tenth century, Egypt's Nile Delta had just two major Delta branches debouching directly into the Mediterranean – the Dumyā? (Damietta) and Rashīd (Rosetta). Navigational conditions at these branches’ mouths were treacherous because of a combination of currents, winds, wave-fields and shifting sandbanks. These conditions were a danger to shipping, and so had a formative effect on the navigational landscape of the Delta. Despite its remoteness from the Nile, Alexandria remained Egypt's chief Mediterranean port, but only because river connections were maintained that avoided the Rashīd mouth. In contrast, the port of Rashīd was relatively insignificant. Similar conditions at the Dumyā? mouth prompted navigators to adopt routes via Lake Tinnīs, modern Lake Manzala, which linked to the sea through its calmer sea mouths. This article brings together material from multiple disciplines to offer a new understanding of the navigational context of Egypt's medieval Mediterranean ports.  相似文献

Confidence Intervals for a Semiparametric Approach to Modeling Nonlinear Relations among Latent Variables     

Jolynn Pek  Diane Losardo  Daniel J. Bauer 《Structural equation modeling》2013,20(4):537-553

Compared to parametric models, nonparametric and semiparametric approaches to modeling nonlinearity between latent variables have the advantage of recovering global relationships of unknown functional form. Bauer (2005) Bauer, D. J. 2005. A semiparametric approach to modeling nonlinear relations among latent variables. Structural Equation Modeling, 12: 513–535. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar] proposed an indirect application of finite mixtures of structural equation models where latent components are estimated in the service of more flexibly recovering characteristics of the latent aggregate regression function. This article develops and evaluates delta method and parametric bootstrap approaches for obtaining approximate confidence intervals for Bauer's semiparametric approach to modeling latent nonlinear functions. Coverage rates of these approximate point-wise confidence intervals or nonsimultaneous confidence bands are evaluated by Monte Carlo and recommendations for their use are suggested.  相似文献
