 | To reduce the risk of and damage from fires, naval engineers have suggested reducing the oxygen concentration in submarines below the normal ambient level of 21% (PO2 = 159 torr). However, reductions to 13% oxygen (PO2 = 99 torr) may produce decrements in mental and physical performance, changes in mood states, or symptoms of acute mountain sickness (AMS). To investigate these possibilities, thirteen male sailors were confined and tested in ... |

 | Rigorous testing instruments and psychometric methods are required to assess the effects of enviromental stressors upon cognitive performance. This paper presents findings and illustrates our methodology for evaluating the effects of several types of environmental stressors. Various cognitive performances were investigated experimentally with paper and pencil tasks in repeated-measures paradigms for several high altitudes, altitude-treatment strategy, dehydration cold, atropine in a hot environment. Cognitive performances was to decreases in the ... |

|
| There are conflicting reports in the literature which imply that the decrement in maximal aerobic power experienced by a sea-level (SL) resident sojourning at high altitude (HA) is either smaller or larger for the more aerobically fit person. In the present study, data collected during several investigations conducted at an altitude of 4300 m were analyzed to determine if the level of aerobic fitness influenced the decrement in maximal oxygen ... |

|
| The study provides information about (1) the decay of heat acclimatization over periods of 3, 6, 12 and 18 days assessed by an evaluation of the residual retention, (2) the time necessary for reacclimatization and (3) the relative importance of physical condition in these processes. |

|
| The influence of posture on isometric muscular capacity has been examined on four subjects in the sitting, 45 degrees head-up, recumbent and 15 degrees head-down position. The maximal voluntary contraction (MVC) of the subjects' hand-grip was unaffected by posture, but the endurance time of an isometric contraction held to fatigue at 40% MVC was 20% longer in the sitting than in any other posture. That difference in endurance was abolished ... |
