The slow sarco/endoplasmic reticulum Ca2+-ATPase declines independently of slow myosin in soleus muscle of diabetic rats [PDF]

, 2009
The sarcoplasmic reticulum Ca2+-ATPase (SERCA) isoforms are normally expressed in coordination with the corresponding myosin heavy chain (MyHC) isoforms in the fibers of skeletal muscle but this coordination is often disrupted in pathological conditions.

The PGC-1 coactivators promote an anti-inflammatory environment in skeletal muscle in vivo [PDF]

, 2015
The peroxisome proliferator-activated receptor γ coactivator 1α (PGC-1α) is abundantly expressed in trained muscles and regulates muscle adaptation to endurance exercise. Inversely, mice lacking a functional PGC-1α allele in muscle exhibit reduced muscle

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 ...

Capillaries are Embedded in the Sarcolemma of Murine Slow Twitch Skeletal Muscle Fibers

The FASEB Journal, 2012
The purpose of this study was to evaluate the in vivo , 3D spatial relationship between capillaries (CAP), mitochondria (MITO), and three fiber types within murine Tibialis anterior (TA) muscle.

Need for speed: Human fast-twitch mitochondria favor power over efficiency

Molecular Metabolism
Objective: Human skeletal muscle consists of a mixture of slow- and fast-twitch fibers with distinct capacities for contraction mechanics, fermentation, and oxidative phosphorylation.

Comparative analysis of the transcriptomes of EDL, psoas, and soleus muscles from mice

BMC Genomics, 2020
Background Individual skeletal muscles have evolved to perform specific tasks based on their molecular composition. In general, muscle fibers are characterized as either fast-twitch or slow-twitch based on their myosin heavy chain isoform profiles.

Pre-exercise casein peptide supplementation enhances endurance training-induced mitochondrial enzyme activity in slow twitch muscle, but not fast twitch muscle of high fat diet-fed mice

Journal of Physical Fitness and Sports Medicine, 2015
To establish an efficient method of enhancing mitochondrial biogenesis, we investigated the effect of casein peptide supplementation. The aim of this study was to examine whether oral casein peptide ingestion enhances exercise-induced mitochondrial ...

Eicosapentaenoic acid increases proportion of type 1 muscle fibers through PPARδ and AMPK pathways in rats

iScience
Summary: Muscle fiber type composition (% slow-twitch and % fast-twitch fibers) is associated with metabolism, with increased slow-twitch fibers alleviating metabolic disorders.
