The aim of this study was to determine the physiological profile of young triathletes who began triathlon competition as their first sport. Twenty-nine male competitive triathletes (23 regionally and nationally ranked triathletes and 6 elite, internationally ranked triathletes) performed two tests, one on a cycle ergometer (CE VO2max) and one on a treadmill (TM VO2max). Results showed (a) no di...

At first examination, the mean age was similar in both groups. The initial age of migraine attacks was significantly smaller in the TM group. Time history of episod...

Based on comparisons of ear canal and scala vestibuli pressures the gerbil middle ear transmits sound with a gain of approximately 25 dB that is almost flat from 2 to 40 kHz, and with a delay-like phase corresponding to a 25-30 micros delay. How the middle ear is able to transmit sound with such high temporal and amplitude fidelity is not known, and is particularly mysterious given the complex ...
