BACKGROUND AND PURPOSE SWI is a new technique for evaluating diffuse axonal injury associated with punctate hemorrhages. The aim of our study was to determine the prevalence of cerebral microhemorrhages in amateur boxers compared with nonboxers by using SWI and to evaluate the sensitivity of SWI compared with T2 FSE and T2*GE sequences. MATERIALS AND METHODS We performed cranial MR imaging wi...

BACKGROUND Following DIY (do it yourself) diets as well as consuming supplements exceeding by far the recommended daily intake levels, is common among athletes; these dietary habits often lead to an overconsumption of some macro and/or micronutrients, exposing athletes to potential health risks. The aim of this study is to document the development of possible adverse effects in a 33 year-old am...

Objectives—To evaluate the changes produced in both the isocapnic buVering and hypocapnic hyperventilation (HHV) phases of professional cyclists (n = 11) in response to endurance training, and to compare the results with those of amateur cyclists (n = 11). Methods—Each professional cyclist performed three laboratory exercise tests to exhaustion during the active rest (autumn: November), precomp...

Amateur minor hockey coaches have recently begun to capture and play back video recordings to provide their teams with visual feedback of their play as a learning tool. Yet what is not clear is whether such video feedback is useful and how video feedback systems could be designed to better match the needs of amateur hockey coaches and players. As such, we wanted to understand coaches’ current p...

To recover data from spread-spectrum transmissions, it is necessary to reintroduce, at the receiver end, locally generated signals locked in frequency and phase to the clock used in the original transmissions. At carrier frequencies of up to 50 MHz, the extraction of clock pulses from direct-sequence (DS) spreadspectrum transmissions can be achieved fairly easily, using readily available ICs.' ...

Is the underlying cognitive processes different when playing with an opponent whose game play is familiar to that of an unknown? This study filtered the advance cues extracted by expert and amateur players when paired with an opponent whose game play is familiar to that of an unknown opponent. Our data collected in a real-life naturalistic game play conditions suggests that at the beginning of ...
