Expression of aquaporin-4 in fast-twitch fibers of mammalian skeletal muscle. [PDF]
Journal of Clinical Investigation, 1998 In this study we analyzed the expression of aquaporin-4 (AQP4) in mammalian skeletal muscle. Immunohistochemical experiments revealed that affinity-purified AQP4 antibodies stained selectively the sarcolemma of fast-twitch fibers. By immunogold electron microscopy, little or no intracellular labeling was detected.

High-speed jaw-opening exercise in training suprahyoid fast-twitch muscle fibers.
Clinical interventions in aging, 2018 This study was aimed to examine the effectiveness of a high-speed jaw-opening exercise, which targets the contraction of fast-twitch muscle fibers, in improving swallowing function.Twenty-one subjects (mean age 74.0±5.7 years) with dysphagia-related symptoms, such as coughing or choking during eating, performed the exercise.

Prediction of muscle fiber composition using multiple repetition testing
Biology of Sport, 2020 Direct determination of muscle fiber composition is invasive and expensive, with indirect methods also requiring specialist resources and expertise. Performing resistance exercises at 80% 1RM is suggested as a means of indirectly estimating muscle fiber ...

Effect of Dietary Restriction on Muscle Performance in Drosophila [PDF]
, 2011 Dietary restriction (DR) can extend the lifespan in various organisms and is thought to present potential benefits in human. However, it is still a controversial issue now among scientists due to lack of strong supportive evidence in human.

Cycling Cross-Bridges Contribute to Thin Filament Activation in Human Slow-Twitch Fibers
Frontiers in Physiology, 2020 It has been shown that not only calcium but also strong binding myosin heads contribute to thin filament activation in isometrically contracting animal fast-twitch and cardiac muscle preparations. This behavior has not been studied in human muscle fibers

Size and Proportions of Slow-Twitch and Fast-Twitch Muscle Fibers in Human Costal Diaphragm [PDF]
BioMed Research International, 2016 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 ...

Role of the JP45-Calsequestrin Complex on Calcium Entry in Slow Twitch Skeletal Muscles [PDF]
, 2016 We exploited a variety of mouse models to assess the roles of JP45-CASQ1 (CASQ, calsequestrin) and JP45-CASQ2 on calcium entry in slow twitch muscles.

Noninvasive Estimation of Myosin Heavy Chain Composition in Human Skeletal Muscle [PDF]
, 2011 Purpose: Information on muscle fiber type composition is of great importance in muscle physiology and athletic performance. Because there are only a few techniques available that noninvasively and accurately provide an estimate of muscle fiber type ...
