Highly significant responses to anthropogenic forcings
It has been suggested that changes in the atmospheric circulation caused by anthropogenic forcings are highly uncertain, owing to the large natural variability intrinsic to the system. Here, to assess the statistical significance of such changes for the midlatitude, large-scale atmospheric circulation of the Southern Hemisphere, we analyze a new 40-member ensemble of integrations, from 1920 to ...
متن کاملCardiorespiratory responses to physical work during and following 17 days of bed rest and spaceflight.
To determine the influence of a 17-day exposure to real and simulated spaceflight (SF) on cardiorespiratory function during exercise, four male crewmembers of the STS-78 space shuttle flight and eight male volunteers were studied before, during, and after the 17-day mission and 17 days of -6 degrees head-down-tilt bed rest (BR), respectively. Measurements of oxygen uptake, pulmonary ventilation...
متن کاملHaematological and cardiorespiratory responses to induced hyperpyrexia.
ELEVATION of body temperature has been shown to produce altered haematological functions in both man and animals3 ,2,z,4 Heat stroke and malignant hyperpyrexia are two clinical syndromes which document these disturbances. ~,6 The syndrome of heat stroke causes haematological changes associated with exertion in an atmosphere of raised effective temperature (E.T.); temperature corrected for humid...
متن کاملCardiorespiratory interactions during resistive load breathing.
The addition to the respiratory system of a resistive load results in breathing pattern changes and in negative intrathoracic pressure increases. The aim of this study was to use resistive load breathing as a stimulus to the cardiorespiratory interaction and to examine the extent of the changes in heart rate variability (HRV) and respiratory sinus arrhythmia (RSA) in relation to the breathing p...
متن کاملCardiorespiratory responses to stationary running in water and on land.
The aim of the study was to compare maximal and submaximal cardiorespiratory responses between progressive tests on a treadmill on land (TRE), and stationary running on land (SRL) and in water (SRW), while also comparing two methods of determining the second turn point (ST) (ventilatory curve and heart rate deflection point). The study sample consisted of nine active women (23 ± 1.94 years) tha...
