Understanding how muscle length impacts force production is useful when designing a weight training program to optimise functional strength. According to the force-length relationship, at which length is maximal force achieved in the muscle?
at normal resting length, as the number of cross bridges formed is minimised
beyond normal resting length, as the number of cross bridges formed is increased
less than normal resting length, as the number of cross bridges formed is increased
at normal resting length, as the number of cross bridges formed is increased
The microstructure of the muscle is made up of different components. Which two components are being identified by (i) and (ii)?
(i) the contractile unit of the muscle
(ii) the area in the contractile unit containing only the thick myosin filament
(i) sarcomere (ii) A band
(i) I band (ii) H zone
(i) I band (ii) A band
(i) sarcomere (ii) H zone
Skeletal muscles contain three distinct layers of connective tissue.
Identify and outline the three types of connective tissue found in skeletal muscle.
Sporting activities such as basketball, require short bursts of sprinting and jumping and sustained periods of running up and down the court.
Name and explain the predominant muscle fibre type that would be most beneficial to a basketball player.
A golfer attempting to perform a delicate putt uses many of the same muscles as they do to forcefully drive a ball down a fairway.
Describe two ways in which a golfer can control the forcefulness of their muscle contractions for their desired swing.
Explain two factors that can affect the coefficient of restitution (COR) of a golf ball.
Western Australian Jack Della Maddalena is a professional mixed martial artist (MMA) who competes in the global Ultimate Fighting Championship (UFC).
Part of Jack’s preparation for an upcoming fight is sparring. This involves him and another fighter wearing helmets while practice fighting. Name the category of transfer of learning that is occurring in this situation and justify its selection.
Throughout his school years, Jack played rugby union and represented the University of Western Australia before taking up MMA. State the effect of transfer of learning that Jack might experience, from the rugby skills below.
