The relationship between the exercise-induced growth and the endogenous controls of growth was examined in 356 golden hamsters of which equal numbers were given access to horizontal disc exercisers and maintained sedentary at different ages (17 and 42 days) and body weights (25-180 g). Hamsters started exercising around Day 35, increased their activity levels to 30,000 revolutions per day (RPD) by Day 35, and ran progressively less as their weight increased above 65 g. Exercise accelerated growth only in hamsters which have entered the slow asymptotic phase of growth, which weighed between 60-180 g and generated over 15,000 RPD.. Disc exercise appears to reinstate higher rates of ponderal and linear growth after hamsters have entered the slow asymptotic phase of growth. Sustained inhibition of exponential growth may participate in the long-term regulation of body size in adult rodents.

Alternating movements of the limbs during a seizure, especially bicycling movements of the legs, are often taken as strong evidence for the psychogenic origin of seizure activity in an adult population. A recent review of pseudoseizure manifestations concluded that alternating limb movements were "highly characteristic of pseudoseizures." We report two adult patients with complex partial seizures of temporal lobe origin, confirmed by ictal video EEG recording, in whom bicycling movements were the prominent ictal manifestation. Bicycling occurred 5-30 s after ictal onset and lasted 15-30 s. Use of video EEG recording continues to increase our understanding of the wide range of behaviors which may occur in the course of an epileptic seizure, particularly complex partial seizures. Few absolute clinical criteria remain to distinguish epileptic seizures from pseudoseizures. These two cases and one other reported case clearly remove bicycling movements from that category.
