Muscle fibres, contractions and injuries

The muscles mainly responsible for making movements are known as

• Agonists

• Reciprocal inhibition

• stabilisers

• fixators

The paired movement of a muscle is called

• Reciprocal inhibitions

• agonist

• all or nothing

• antagonist

he muscle fibres responsible for explosive movements are called

• explosive twitch.

• fast-twitch oxidative

• slow-twitch.

• fast twitch glycolytic

Pushing against an immoveable wall is an example of what type of muscular contraction?

• concentric

• isometric

• eccentric

• isoinertial

The cross bridges during muscle contractions continue to detach and reattach themselves from the

• myosin filaments

• sarcomere filaments

• actin filaments

• muscle fibre filaments

muscle strain is an example of

• acute injury

• a chronic injury

• an overuse injury

• a sprain

Excessive movement of a joint outside of its range of motion is most likely to result in which type of injury?

• Contusion

• laceration

• over use injury

• dislocation

Which of the following is an example of an overuse injury?

• broken wrist

• shin splints

• concussion

• hamstring strain

direct injuries occur when

• a joint bone or muscle is used excessively

• an external force causes damage to tissue

• an athlete over stretches and tears their hamstring

• poor technique results in a stress fracture
