skeletal muscle contraction

A process in which force is generated within skeletal muscle tissue, resulting in a change in muscle geometry. Force generation involves a chemo-mechanical energy conversion step that is carried out by the actin/myosin complex activity, which generates force through ATP hydrolysis. In the skeletal muscle, the muscle contraction takes advantage of an ordered sarcomeric structure and in most cases it is under voluntary control.

transition between fast and slow fiber

The process of conversion of fast-contracting muscle fibers to a slower character. This may involve slowing of contractile rate, slow myosin gene induction, increase in oxidative metabolic properties, altered electrophysiology and altered innervation. This process also regulates skeletal muscle adapatation.

GO:0030049

muscle filament sliding

The sliding of actin thin filaments and myosin thick filaments past each other in muscle contraction. This involves a process of interaction of myosin located on a thick filament with actin located on a thin filament. During this process ATP is split and forces are generated.

GO:0031444

slow-twitch skeletal muscle fiber contraction

A process in which force is generated within slow-twitch skeletal muscle tissue, resulting in a change in muscle geometry. Force generation involves a chemo-mechanical energy conversion step that is carried out by the actin/myosin complex activity, which generates force through ATP hydrolysis. The slow-twitch skeletal muscle is characterized by slow time parameters, low force development and resistance to fatigue.

negative regulation of muscle contraction

Any process that stops, prevents, or reduces the frequency, rate or extent of muscle contraction.

troponin complex

A complex of accessory proteins (typically troponin T, troponin I and troponin C) found associated with actin in muscle thin filaments; involved in calcium regulation of muscle contraction.

GO:0005523

tropomyosin binding

Interacting selectively and non-covalently with tropomyosin, a protein associated with actin filaments both in cytoplasm and, in association with troponin, in the thin filament of striated muscle.

GO:0031014

troponin T binding

Interacting selectively and non-covalently with troponin T, the tropomyosin-binding subunit of the troponin complex.
