Strength is the
highest force developed
The highest muscle force can be achieved during a maximal
eccentric muscle
In Lab 2, the maximum force developed during a single contraction represented
strength
Maximum force of skeletal muscle is
inversely proportional to the velocity of muscle shortening
The cross-bridge cycle
describes the process of myosin attachment, power stroke and detachment from actin
The neurotransmitter which causes muscle cells to contract is
acetylcholine
Key steps involved in muscle relaxation include
cessation of release of acetylcholine and repolarisation of the sarcolemma
During concentric actions, muscle strength is increased
by slowing down the movement speed
The highest force developed during an eccentric action
occurs at relatively moderate lengthening speeds
Muscle strength will be greatest when
100 % of the motor unit pool is recruited
