Ham Complex

Question 1

Biceps Femoris Long Head C, E, I

Answer 1

C- accelerates knee flexion, hip extension and tibial external rotation
E- decelerates knee extension, hip flexion, and tibial internal rotation
I- stabilizes the lumbo-pelvic-hip complex and knee

Question 2

Biceps Femoris Short Head c, E, I

Answer 2

C- accelerates knee flexion and tibia external rotation
E- decelerates knee extension and tibia internal rotation
Isometrically stabilizes the knee

Question 3

Semimembranosus c, e, i

Answer 3

C- accelerates knee flexion, hip extension, and tibia internal rotation
E- decelerates knee extension, hip flexion, and tibia external rotation
Isometrically stabilizes lumbo-pelvic-hip complex and knee

Question 4

Semitendinosus C, E, I

Answer 4

C- accelerates knee flexion , hip extension, and tibia internal rotation
E- decelerates knee extension, hip flexion, and tibia external rotation
I- stabilizes the lumbo-pelvic-hip complex and knee
