Electromyographic timing analysis of forward and backward cycling

Article Abstract:

Use of backward cycling during the early recovery phase to achieve a selective hamstring muscle response of relatively decreased patellofemoral stress and anterior cruciate ligament (ACL) strain seems well founded in functional knee rehabilitation. An electromyographic (EMG) and motion analysis study has been carried out to compare the activation duration of the vastus lateralis, vastus medialis, rectus femoris, lateral hamstring, medial hamstrings, tibialis anterior and gastocnemius muscles during backward and forward cycling. Backward walking-to-running progressions are an increasingly popular nontraditional part of knee rehabilitation plans.

Arterial oxygen desaturation kinetics during apnea

Article Abstract:

An investigation conducted to study the diving response and the rate of arterial oxygen desaturation during face immersion apnea in divers, capable of extended apnea durations is discussed. The sigmoidal function provided no quantifiable difference in the rate of oxygen desaturation.
