Muscle firbre types and types of contraction

Question 1

Fast twitch (Anaerobic)

Answer 1

• larger
• white
• high force
• fast speed of contraction
• medium/low resistance of fatigue

Question 2

Slow twitch (Aerobic)

Answer 2

• smaller muscle
• red
• low force
• slow speed for contraction
• high resistance of fatigue

Question 3

isotonic muscle contraction

Answer 3

• concentric –> shortening the muscle
• eccentric –>lengthning the muscle
• example workout: bench press

Question 4

isometric muscle contraction

Answer 4

• stable
• still challenging the muscle but not changing the muscle length
• example workout: wall sit

Question 5

isokinetic muscle contraction

Answer 5

• the resistance stays the same
• equal force through an entire range of movement
• example workout: mostly machine
