N2 - Physical and cognitive performance has been the subject of various studies conducted in the laboratory. However, physiological adaptations, unique exercise modalities, and environmental stressors might affect performance in extreme environments. Therefore, some laboratory findings have only limited value in contexts like underwater or microgravity. More specific insights can be gained from applied studies in sports contexts or analog studies that simulate selected aspects. Within this cumulative dissertation, physical and cognitive performance was assessed for the contexts of spaceflight and the practical sport of SCUBA-diving. Long-duration spaceflight was simulated during 120-days of isolation in a terrestrial analog, and weightlessness during extra-vehicular activity in space by water submersion with matching exercise and cognitive-motor tasks. Furthermore, the specific influencing factors of elevated partial gas pressures and the modality of underwater fin-swimming were investigated in an applied setting in SCUBA-diving. Based on the unique conditions of the underwater environment, different educational methods were assessed on their outcome on movement skill performance. For the simulation of spaceflight, results showed attenuating effects of isolation on the effectiveness of countermeasure exercise training on aerobic fitness. Executive functions were affected selectively by simulated extra-vehicular activity underwater, and shifting accuracy deteriorated significantly after high-intensity exercise. In SCUBA-diving, positive effects with a decrease of minute ventilation were revealed for higher inspiratory oxygen pressures during high-intensity exercise and some parameters of executive functions improved after exercise. However, these effects did not fully correspond to laboratory findings, suspecting sport-specific or environmental influences. Discovery learning, as an alternative educational method in SCUBA-diving, evoked adequate movement skill performance in diving beginners. Still, the expected benefits of a higher sustainability from assumed implicit learning processes were not identified. The various sport-specific and environmental factors affect physical and cognitive performance with implications for safety. Future studies should aim to identify individual modulators and their role on performance.
