Increased wheel-running activity in the genetically skeletal muscle fast-twitch fiber-dominant rats

Journal of Applied Physiology, 2003
The purpose of the present study was to investigate whether genetic differences in muscle histochemical characteristics were related to the voluntary wheel-running activity level by using genetically fast-twitch fiber-dominant rats (FFDR) and control rats (CR).

Does metabosensitive afferent fibers activity differ from slow- and fast-twitch muscles?

Experimental Brain Research, 2015
This study was designed to investigate the metabosensitive afferent response evoked by electrically induced fatigue (EIF), lactic acid (LA) and potassium chloride (KCl) in three muscle types. We recorded the activity of groups III-IV afferents originating from soleus, gastrocnemius and tibialis anterior muscles.

Capillary-to-fiber surface ratio in rat fast-twitch hindlimb muscles after chronic electrical stimulation

Journal of Applied Physiology, 1996
We examined the relative plasticity of capillaries and fiber mitochondria in rat fast-twitch hindlimb muscles in response to chronic electrical stimulation. Specifically we addressed whether the size of the capillary-fiber interface increases in proportion to fiber mitochondrial volume, inasmuch as fiber aerobic capacity increases severalfold with ...

Heterogeneity of myosin heavy-chain expression in fast-twitch fiber types of mature avian pectoralis muscle

Biochemistry and Cell Biology, 1996
The aims of this study are to investigate the diversity of myosin heavy-chain (MyHC) expression among avian fast-twitch fibers, and to test the hypothesis that dissimilar MyHC isoforms are found in each of the principal avian fast-twitch fiber types.

Morphological changes during fiber type transitions in low-frequency-stimulated rat fast-twitch muscle

Cell & Tissue Research, 1994
This study investigates morphological adaptations of rat extensor digitorum longus muscle to chronic low-frequency stimulation (10 Hz, 10 h/d, up to 61 +/- 7d). During the early stimulation period (2-4 d), increased basophilia and accumulation of RNA were seen predominantly in type-IIB fibers.

Anterior Cruciate Ligament Injury Is Associated With Fast Twitch Hamstring Muscle Fiber Typology

Scandinavian Journal of Medicine & Science in Sports
ABSTRACT Anterior cruciate ligament (ACL) injuries are one of the most common acute sports injuries in male football. Recently, the role of muscle fiber type (MFT) distribution in both athletic performance and hamstring muscle injury risk has gained popularity in sports medicine.
