Muscular: Types of skeletal muscle contractions

Question 1

Isometric

Answer 1

-Muscle contracts but little to no movement
-Length doesn’t change
-Angle at joint stays the same

Examples: Plank, wall sit, press up hold

Question 2

(Isometric)
Concentric

Answer 2

-Upward phase
-Positive phase
-Muscle will get shorter/fatter during contraction

Examples: Upward phase of
-a bicep curl
-press up
-squat

Question 3

(Isometric)
Eccentric

Answer 3

-Downward phase
-Negative phase
-Muscle will get longer/thinner during contraction
-Tear more fibres (gain muscle)

Examples: downward phase of
-a bicep curl
-press up
-squat
