Inhibit muscle contraction

None of the answers are correct

Reduce in number

Ca²⁺ have nothing to do with muscle contraction

The mitochondria act as a store of Ca2+ for the contractile process

A rise in intracellular Ca²⁺ allows actin to interact with myosin

A fall in intracellular Ca²⁺ allows actin to interact with myosin

None of the answers are true

Little-to-no change in muscle length

A lengthening of the muscle

None of the answers are correct

A shortening of muscle length

Lengthening, followed by a shortening of the muscle

A muscle will gain its greatest tension when the muscle reaches its shortest length

None of the above are correct

A muscle will gain its greatest tension when the muscle reaches its greatest length

A muscle will gain its greatest tension when the largest number of thin and thick filaments are not overlapping

A muscle will gain its greatest tension when the largest number of thin and thick filaments are overlapping

None of the answers are correct

Increased forced production

Increased recruitment of type I muscle fibres

Increased contraction velocity

No change in the muscle length

A shortening, followed by a lengthening of the muscle

A shortening of the muscle length

A lengthening, followed by a shortening of the muscle
