Power developed by motor units of the peroneus tertius muscle of the cat.
The mechanical properties of motor units have been extensively studied under isometric conditions. Under dynamic conditions, the relationship between the force developed by single motor units and the muscle shortening velocity was determined for relatively high frequencies of activation. However, the interaction between the force-shortening velocity relation and the force-rate of activation rel...
متن کاملRupture of the peroneus tertius tendon in 27 horses.
The purpose of the study was to identify factors influencing the outcome and prognosis of rupture of the tendon of the peroneus tertius muscle in 27 horses. Information on history, physical examination findings, diagnosis, treatment, and final outcome was summarized from medical records. Long-term follow-up information on horses was obtained by telephone survey. A stepwise logistic regression m...
متن کاملNonlinear tension summation of different combinations of motor units in the anesthetized cat peroneus longus muscle.
The purpose of this study was to examine the linearity of summation of the forces produced by the stimulation of different combinations of type identified motor units (MUs) in the cat peroneus longus muscle (PL) under isometric conditions. The muscle was fixed at its twitch optimal length, and the tension produced by the single MU was recorded during 24- and 72-Hz stimulation. The summation ana...
متن کاملPeroneus Tertius Tendon Tear: A Rare Cause of Lateral Ankle Pain
The peroneus tertius (PT) muscle is a variably present muscle, uncommonly found in humans. Injury to the PT tendon is rare with virtually no cases reported in the literature. As a consequence of the rarity of this injury, there is little clinical information regarding injury or rupture of the PT muscle and tendon. We present a case of injury involving this rare anatomical variant. Magnetic reso...
متن کاملRegulation of skeletal muscle carbohydrate oxidation during steady-state contraction.
Pyruvate dehydrogenase complex (PDC) activation status has been described as being central in the regulation of tissue substrate oxidation as outlined by the glucose fatty-acid cycle. In the present study we examined the effects of reduced lipolysis, with use of nicotinate, and increased PDC activation, with use of dichloroacetate (DCA), on substrate utilization during 20 min of submaximal stea...
