In search of more detailed explanations for body-mind interactions in physical activity, neural and physiological effects, especially regarding more strenuous sports activities, increasingly attract interest. Little is known about the underlying manifold (neuro-)physiological impacts induced by different motor learning approaches. The various influences on brain or cardiac function are usually studied separately and modeled linearly.

This study aimed to analyze effects of increasing exercise intensity on brain activity (spontaneous EEG), heart rate variability (HRV) and rating of perceived exertion (RPE) by means of a graded exercise test (GXT). Fifteen participants performed an open-loop GXT on a bicycle ergometer beginning at 50W and an increment of 50W every three minutes.

This is the first report on the preoperative use of an inflatable balloon to prevent massive hemorrhage by inserting the balloon--a procedure performed in the cardiac catheterization laboratory--before rethoracotomy. A false ascending aortic aneurysm was successfully sealed by transaortic wire-guided balloon placement from the iliac artery.
