“…11,12 As well as limited exercise tolerance at high altitudes, mental and cognitive capacities are reported to be reduced under simulated conditions, 13 which may then result in an overestimation of one's own exercise capacity. 14 The purpose of this controlled study was to assess the autonomic and hemodynamic responses of patients after MI and preserved left ventricular (LV) systolic function during short-term stays (1-4 h maximum) at high altitude (Jungfraujoch, Swiss Alps, 3,564 m). In order to investigate the ability of the autonomic nervous system to cope with stress conditions, we used mental stress testing.…”

Background: High sympathetic tone creates a significant risk for ventricular arrhythmias and sudden death, which can especially affect patients after a myocardial infarction (MI) when exercising in a hypoxic environment. Methods and Results: The 16 patients after MI and 10 normal volunteers (NV) underwent a 1-day trip from low altitude (540 m, Bern) to high altitude (3,564 m Jungfraujoch, Swiss Alps). Autonomic function under resting and mental stress conditions at low and high altitude was assessed. MI patients demonstrated a significantly lower stroke volume (P<0.05) at rest compared with the NV at low as well as high altitude. High altitude exposure was accompanied by higher low-frequency/high-frequency values in the MI patients compared with NV (P<0.01). Following mental stress, MI patients failed to show the normal return to resting values at high altitude, suggesting sustained sympathetic and diminished parasympathetic activation during post-stress recovery. Conclusions: Although all MI patients were either on β-blockers or AII inhibitors, they showed higher sympathetic activity during exposure to high altitude compared with NV. In addition, the respective parasympathetic tone was reduced, especially during recovery. This puts patients after MI at an increased risk for cardiac arrhythmias and they should be advised of this if going to high altitudes. (Circ J 2009; 73: 1485 -1491

“…It is well documented that strenuous physical exercise performed in external environments such as altitude, heat and cold impose increased psychological and physiological stress (Acevedo & Ekkekakis, 2001;Bolmont, Thullier, & Abraini, 2000;Gleeson, 2000;Pyne, Gleeson, & Mcdonald, 2000). Environmental changes can influence psychological functioning before affecting physiological factors (Kobrick & Johnson, 1991).…”

Abstract-During hypoxia conditions, psychological states can be worsened. However, little information is available regarding the effect of physical exercise performed in hypoxia conditions on mood state and anxiety symptoms. The aim of the present study was to elucidate the acute effect of moderate physical exercise performed at hypoxia on mood states and anxiety symptoms in healthy young subjects. Ten volunteers were subjected to the following conditions: a normoxic condition (NC) and a hypoxic condition (HC). They performed 45 min of physical exercise. Their anxiety symptoms and mood states were evaluated at the initial time point as well as immediately following and 30 and 60 min after the exercise session. Our results showed a significant increase in post-exercise anxiety symptoms and a significant decrease in mood scores immediately after and 30 min after exercise performed in the HC. Moderate physical activity performed at hypoxia condition increased post-exercise anxiety and worsened mood state.Keywords: physical activity, hypoxia, mood state, anxietyResumo-"Exercício realizado em hipóxia influencia o estado de humor e sintomas de ansiedade." Em condição de hipóxia o aspecto psicológico pode piorar, porém, ainda há pouca informação sobre a resposta do exercício físico realizado nestas condições sobre o estado de humor e os sintomas de ansiedade. O objetivo deste estudo foi investigar o efeito agudo do exercício físico moderado realizado em condição de hipóxia sobre o estado de humor e sintomas de ansiedade de jovens saudáveis. Dez voluntários foram submetidos a duas condições: Condição Normóxia (CN) e Condição Hipóxia (CH) e realizaram 45' de exercício físico. Os sintomas de ansiedade e humor foram avaliados no momento basal, imediatamente após, 30 e 60 minutos. Observou-se um aumento significativo dos sintomas de ansiedade pós-exercício físico e uma redução significativa dos escores de humor em condição de hipóxia imediatamente e após 30 minutos de exercício. O exercício físico moderado realizado em condição de hipóxia promove uma resposta ansiogênica pós-exercício físico e piora do estado de humor.

“…Particularly, Wang Y, et al [20], had conducted a questionnaire-based investigation of emotional responses and psychological adaptation over 520 days' isolation, and results had demonstrated an obvious bias on valence rating for unpleasant stimuli with time (p<0.05), thus may explain the elevation of serotonin at period two. Furthermore, the presence of increased psychosocial issues caused by long-term isolation had been proved by many researches [21][22][23][24][25][26]. Thus these results suggested that physiological problems are very serious in an isolated environment.…”

“…Moreover, aside from MARS-500 project, a number of similar expeditions under isolated and confined environments have found evidence of decrement in the variables of cognitive performance [50], mood states [25], locomotor function [47], circadian rhythm and sleep [29], etc. However, results presented here therefore raised another questions: Did crews from MARS-500 project present the same responses for these psychological and physiological indexes?…”

# These authors contributed equally to this work. metabolic profiles through analyzing complex biofluids (e.g., urine and plasm) can provide important diagnostic and prognostic information [8]. Among the biofluids most commonly analyzed in metabolomic studies, urine appears to be particularly useful, because it is abundant, readily available, easily stored and can be collected by simple, noninvasive techniques [9]. Although, persistent alterations induced by dietary or chronic interventions may also be detected from plasma, but it just provides a description of the metabolic system at the time of sampling, and yet some biochemical or pathological changes may not be specific to external stimuli or genetic modification. By contrast, information from urine is time-averaged because of its collection and storage in the bladder [8]. Therefore, urine was selected to conduct metabolic mapping in many publications [10][11][12]. Among analytical techniques used in metabonomics, nuclear magnetic resonance (NMR) [13] and mass spectroscopy (MS) [14] possessed the dominant status. As known, NMR has the advantage of being rapid, high reproducibility, nondestructive to samples, applicable to intact biomaterials and rich in chemical structural information. In addition, unlike GC-MS and certain liquid chromatography-mass spectrometry (LC-MS) methods,
