Facts Flashcards
“What is the primary site where muscle contraction occurs according to the sliding filament theory, and what process enables myosin to pull actin filaments during muscle contraction?”
myofibril. During muscle contraction, myosin attaches to actin filaments and pulls them by ATP, generating the force necessary for muscle movement. This process involves the sliding of actin and myosin filaments past each other, leading to muscle shortening (concentric ) or lengthening (eccentric) depending on external forces applied to the muscle.
What are fast twitch fibers like
Fatigue fast but are high force productions like in sprints
What can you say about slow twitch
Good for endurance but low force production , ex is marathon runners
What will increase force production
Increase in cross sectional area of muscle fibers
What can you say about muscle fibers #
The more one possess the more force production they create
Rate of stimuli …
Is where brain sends twitch to muscle , the more twitches stack together build more force to point of max of
True or false . Brain stimulus muscles to contract
True
What can you say about fiber recruitment ?
It starts slow but increases once it sees more force is needed
What has an indirect relations with force , max force is used slowest
Concentric
What had an direct relationship with force , and velocity down
Eccentric
True or false. As force goes up velocity goes down but when force goes down velocity goes up ?
True
