Changes In Eeg During Ultralong Running, M. Doppelmayr, P. Sauseng, H. Doppelmayr, I. Mausz

Journal of Human Performance in Extreme Environments

There are only a few studies using human electroencephalograms (EEGs) to investigate bioelectrical changes in the brain during exercise (running or cycling). These studies report an increase in EEG alpha amplitude during and immediately after exercise. However, only exercises within a relatively short time interval of approximately 1 hour have been investigated. Thus, we focussed on long-lasting exercise and report three single case studies, performed on the same participant, during extended exercise and under different thermal conditions. EEG was recorded during a 12-, 24-, and 56-hour ultramarathon. The 56-hour race was performed under extreme thermal stress in Death Valley, CA, …


Perceived Motion Sickness And Effects On Performance Following Naval Transportation, Joakim Dahlman, Torbjörn Falkmer, Fredrik Forsman Oct 2012

Perceived Motion Sickness And Effects On Performance Following Naval Transportation, Joakim Dahlman, Torbjörn Falkmer, Fredrik Forsman

Journal of Human Performance in Extreme Environments

The present study focused on the relationship between previous experiences of, and rated susceptibility to, motion sickness and its correlation to subjective measurements and actual performance. Performance was measured in terms of shooting precision among 23 participants from the Swedish amphibious corps after transportation in a small amphibious boat, while sealed off with no reference to the outside world. Self-rating questionnaires were collected regarding perceived performance and presence of motion sickness. The physiological status perceived by each participant was related to factors that generally indicate early stages of motion sickness, which also were correlated to deficits in performance. It was …


Investigating Visual Alerting In Complex Command And Control Environments, Jacquelyn M. Crebolder Oct 2012

Investigating Visual Alerting In Complex Command And Control Environments, Jacquelyn M. Crebolder

Journal of Human Performance in Extreme Environments

A series of experiments was conducted to investigate visual alerting in complex command and control environments, where operators must use several displays to perform tasks. In the first experiment, the speed of detection of two alerts, one in the form of a short bar and the other a border surrounding the perimeter of the display, were compared under flashing and static states. Findings showed that bar alerts were detected faster than border alerts and that adding a flashing attribute did not provide a benefit. The second study monitored which display participants were attending to when the alert appeared, and the …


Sleep Disturbance Implications For Modern Military Operations, Douglas R. Lindsay, Jeff Dyche Oct 2012

Sleep Disturbance Implications For Modern Military Operations, Douglas R. Lindsay, Jeff Dyche

Journal of Human Performance in Extreme Environments

As is evident from current military operations that are happening around the globe (e.g., Iraq, Afghanistan, Korea), today’s military is being called on in numerous new and innovative ways (e.g., Foster & Lindsay, 2011). One of the primary forces behind this change is the pervasiveness of enhanced information systems. In fact, the concept of networked warfare is the basis of operations and doctrine for the armed forces (Wesensten, Belenky, & Balkin, 2005). With respect to Admiral Cebrowski’s quote, it appears that this notion of information in warfare is going to continue to influence the way that we approach and conduct …
