MusculoSkeletal A Sprinter wants to go faster!

A sprinter specialized in 100 meters fast runs has developed very strong thigh extensors. However, his coach has noticed that there's not enough antagonism to his strong muscles to develop fast sprinting running action.
Which of the following muscles if trained well would help this athlete?

A) Adductor magnus
B) Iliopsoas
C) Rectus femoris
D) Sartorius
E) Vastus lateralis
F) Vastus medialis

Note) This question is written by me, I am not copying from other sources.

B) Iliopsoas

Iliopsoas is the strongest hip flexor. Rectus femoris and sartorius are also flexors of the hip but are not as strong

I remember that Iliopsoas is a hip flexor because this is the muscle that causes strain to nerve roots during the straight leg raise

Correct Answer Correct Answer is B

@ apx85, you got the right answer.
The iliopsoas the strongest hip flexor and it's often forgotten by athletes as it is internal and they don't see it, therefore there should be an exercise program to strengthen it so that it can adequately antagonize the strong hip extensors to have faster sprinting.
