Chronic hypobaric hypoxia increases isolated rat fast-twitch and slow-twitch limb muscle force and fatigue.
Chronic hypoxia alters respiratory muscle force and fatigue, effects that could be attributed to hypoxia and/or increased activation due to hyperventilation. We hypothesized that chronic hypoxia is associated with phenotypic change in non-respiratory muscles and therefore we tested the hypothesis that chronic hypobaric hypoxia increases limb muscle force and fatigue. Adult male Wistar rats were...
متن کاملProperties of the fragmented sarcoplasmic reticulum from fast twitch and slow twitch muscles.
Skeletal muscle of guinea pigs is composed of at least three types of fibers which are distinguishable by their kinetic and histochemical properties. Fast twitch muscles may be histochemically red or white; fragmented sarcoplasmic reticulum (FSR) prepared from both types of fast twitch muscles has identical calcium-accumulating capacity (maximal calcium uptake) and calcium-concentrating ability...
متن کاملIncreased susceptibility to fatigue of slow- and fast-twitch muscles from mice lacking the MG29 gene.
Mitsugumin 29 (MG29), a major protein component of the triad junction in skeletal muscle, has been identified to play roles in the formation of precise junctional membrane structures important for efficient signal conversion in excitation-contraction (E-C) coupling. We carried out several experiments to not only study the role of MG29 in normal muscle contraction but also to determine its role ...
متن کاملThe aerobic maternal exercise increases PDK4 gene expression in slow and fast twitch muscles of rat male offspring.
Recent studies indicate that environment can modify skeletal muscle gene expression and transcriptional factors in offspring genes. Therefore, exercising can lead to changes in the gene expression of the future generations. One of the important metabolic factors is PDK4, which is known as the main factor in Pyruvate Dehydrogenase Complex (PDC). This study examined the effects of maternal exerci...
متن کاملSize and Proportions of Slow-Twitch and Fast-Twitch Muscle Fibers in Human Costal Diaphragm
Smaller diaphragmatic motor unit potentials (MUPs) compared to MUPs of limb muscles lead to the hypothesis that diaphragmatic muscle fibers, being the generators of MUPs, might be also smaller. We compared autopsy samples of costal diaphragm and vastus lateralis of healthy men with respect to fibers' size and expression of slow myosin heavy chain isoform (MyHC-1) and fast 2A isoform (MyHC-2A). ...
