New Card	10/02/2024	In concentric contraction, muscle fibres {{c1::shorten::shorten / stay the same length / lengthen}}
New Card	10/02/2024	In isometric contraction, muscle fibres {{c1::stay the same length::shorten / stay the same length / lengthen}}
New Card	10/02/2024	In eccentric contraction, muscle fibres {{c1::lengthen::shorten / stay the same length / lengthen}}
New Card	10/02/2024	In concentric contraction, muscle force {{c1::>::<, =, >}} load
New Card	10/02/2024	In isometric contraction, muscle force {{c1::=::<, =, >}} load
New Card	10/02/2024	In eccentric contraction, muscle force {{c1::<::<, =, >}} load
New Card	10/02/2024	Muscle strength is defind as the maximum {{c1::force}} or {{c1::tension output}} generated by a single muscle or muslce group
New Card	10/02/2024	Muslce power is defined as the product of {{c1::force}} and {{c1::velocity}} of muscle action
New Card	10/02/2024	In sarcomeres, there is maximal potential force output when there is the most {{c1::overlap}} between myosin and actin
New Card	10/02/2024	Name the two determinants of muscle force{{c1::Physiological cross sectional area}}{{c1::Muscle fibre type}}
New Card	10/02/2024	Anatomical cross sectional area is less accurate since it assumes muscle fibres run {{c1::parallel}}
New Card	10/02/2024	Physiological cross sectional area is accurate as it measures cross sectional area at an {{c1::angle}}
New Card	10/02/2024	What are the three muscle fibre types{{c1::MHC-I}}{{c1::MHC-IIA}}{{c1::MHC-IIX/D}}
New Card	10/02/2024	MHC-I is {{c1::slow}} twitchIt uses {{c1::oxadative phosphorylation::Primary energy source}}
New Card	10/02/2024	MHC-IIa is {{c1::fast}} twitchIt uses {{c1::oxadative phosphorylation and glycolysis::Primary energy source}}
New Card	10/02/2024	MHC-IIX/D is {{c1::fast(est)}} twitchIt uses {{c1::glycolysis::Primary energy source}}
New Card	10/02/2024	Animals such as rabbits have MHC-II{{c1::B}}
New Card	10/02/2024	As muscle grows, increase in strength is {{c1::greater than::<, =, >}} the increase in cross sectional area
New Card	10/02/2024	Why does strength increase more than the muscular cross sectional area?{{c1::Improved drive to agonist via neural system}}{{c1::Decreased drive to ant…
New Card	10/02/2024	Are elite athletes born or made?Studies of identical twins suggest a {{c1::genetic}} infleunce on muscle fibre type proportiona
New Card	10/02/2024	Are elite athletes born or made?Studies of endurance training show a shift of MHC-IIX to {{c1::MHC-IIA}}, but not completely to {{c1::MHC-I}}
New Card	10/02/2024	In ageing individuals, what are the four changes that contribute to sarcopenia (muscle loss){{c1::Decreased neural activation}}{{c1::Decrease in muscl…
New Card	10/02/2024	In cerebral palsy, as muscles get longer, sarcomeres {{c1::stretch}}
