Criteri diagnostici e terapeutici dell'ipertensione arteriosa in età pediatrica.

An auxiliary thigh-to-pedal power system for bicycles, especially attractive for persons interested in low cost, non-polluting, auto traffic avoiding, energy conserving transportation is disclosed, significantly increasing the total force the cyclist can apply to the pedals for each gear ratio. The system attaches to a conventional bicycle while requiring no attachments such as toe clips, cleats or straps to the elements of the bicycle. It allows uninterrupted force to be applied to the pedals throughout the 360° pedaling cycle, the downstroke being maintained on one pedal while the upstroke is being performed on the other pedal. Unlike prior art upstroke utilization schemes, mounting and dismounting can be performed in a safe manner identical to that for a conventional bicycle, and standup cycling is allowed. Hook and loop attachment material and a snap hook are utilized in adjustably coupling the thigh with the inner end of the pedal.
