Hamstring Complex

Question 1

Biceps Femoris-long head (hamstring complex)

Answer 1

Integrated function:
Eccentrically decelerates knee extension
Eccentrically Decelerates hip flexion
Eccentrically decelerates tibial internal rotation at mid-stance of the gait cycle
Isometrically stabilizes the lumbo-pelvic-hip complex and knee

Question 2

Biceps femoris-short head (hamstring complex)

Answer 2

Integrated function:
Eccentrically decelerates knee extension
Eccentrically decelerates tibial internal rotation
Isometrically stabilizes the knee

Question 3

Semimembranosus (hamstring complex)

Answer 3

Integrated function:
Eccentrically decelerates knee extension
Eccentrically decelerates hip flexion
Eccentrically decelerates tibial external rotation
Isometrically stabilizes the lumbo-pelvic-hip complex and knee

Question 4

Semitendinosus (hamstring complex)

Answer 4

Integrated function:
Eccentrically decelerates knee extension
Eccentrically decelerates hip flexion
Eccentrically decelerates tibial external rotation
Isometrically stabilizes the lumbo-pelvic-hip complex and knee
