What is related to the energy demands of exercising muscle, was the focus of earky exercise physiology researchers of the 20th century?
cellular metabolism
types of muscle tissue
skeletal, cardiac, smooth
Muscle fibers, or muscle cells are held in place by thin sheets of connective tissue membrane that are called...
fasciae
what is the fascia that encases the entire muscle?
epimysium
the dark areas, called A bands, contain the thick filament, primarily made up of...
myosin
also known as muscle growth, is responsible for the strength gains experienced after a prolonged period of resistance training
hypertrophy
what is a main reason for muscle atrophy (or loss of muscle size and strength)?
aging
what is a response to a certain stimulus that is not under conscious control?
reflex
when muscles change length as they produce tension, the actions that take place are referred to as either concentric or...
eccentric
an eccentric action followed immediately by a concentric action is referred to as...
stretch shortening cycle
tendon function
cord-like tissues that connect muscles to bones; transmit force from muscle to bone, thereby producing motion; resist movement in the direction opposite of the force that causes joint movement
ligament function
attach bone at the joints; support the joints by allowing freedom of movement, but are also strong, tough, and inextensible as as not to yield easily to applied forces
fasciae function
sheath-like substance that encases body cavities, muscles, and organs; Perform various functions throughout the body, including supporting innermost body cavities and organs, enabling the safe and effective transmission or forces within the body, and providing lubricated surfaces between muscle fibers that allow muscles to change shape during contraction and elongation
reduction
the addition of an electron to a molecule or an atom
hydrolysis
the breakdown of an adenosine triphosphate (ATP) molecule to adenosine diphosphate (ADP) and inorganic phosphate (Pi) molecules [Show Less]
