Abstract Exercise could prevent physical and psychological deteriorations, especially during pandemic times of lock-down scenarios social isolation. But to meet both, the common exercise protocols require optimization based on holistic investigations with respect underlying processes. This study aimed explore individual chronic acute effects continuous interval running cognitive performance, mood, affect neurophysiological factors a terrestrial simulated space mission.

Isolation is stressful and negatively affects sleep mood might also affect the structure function of brain. Physical exercise improves brain function. We investigated influence physical during isolation on sleep, affect, neurobehavioral N = 16 were isolated for 30 days with daily routines (ISO 100 ) n 45 every second day 50 ). 27 non-isolated controls who either exercised a basis (CTRL Ex or refused NonEx days. At beginning end each intervention, intravenous morning cortisol, melatonin,...
Abstract The beneficial psychological effects of exercise might be explained by self-determination theory and autonomy. However, the underlying neurophysiological mechanisms are even less elucidated. Previously neglected, aperiodic (1/f) brain activity is suggested to indicate enhanced cortical inhibition when slope steeper. This thought associated with an increased cognitive performance. Therefore, we hypothesize that running a self-selected intensity thus given autonomy leads stronger...
Abstract This study evaluated the acute and chronic effects of intermittent continuous Artificial Gravity (AG) on cognitive performance during 60 days Head-down tilt bedrest (HDTBR), a well-established ground-based spaceflight analogue method. Participants were randomly assigned to three groups: AG, HDTBR control group without AG exposure. Task electrophysiological measures attention working memory investigated Simple Complex tasks in Visual Auditory modality. Compared baseline, faster...
