Thoracic outlet syndrome--a functional disturbance of the thoracic upper aperture?

abstract：INTRODUCTION:We examined the extent to which fatiguing cycling exercise in the heat influences contractile function in modulating the force-frequency relationship. METHODS:Before (∽37.0 °C) and after (∽38.5 °C) exercise (ExH) and passive (PaH) hyperthermia, an 8-s train of stimulation at 10, 20, 50, and 100 Hz (2 s pe...
