Psychophysical Differences in Ventilatory Awareness and Breathlessness between Athletes and Sedentary Individuals.

abstract：:Gravity has remained constant during animal evolution and the neural sensory systems detecting acceleration forces have remained remarkably conserved among vertebrates. The utricular organ senses the sum of inertial force due to head translation and head tilt relative to gravitational vertical. Change in gravitational...
