D) Assuming counter clockwise rotations are positive, if the
direction of the hip moment acting on the thigh was negative, what
muscle group would show emg activity? Explain.
Homework Answers
The thigh muscles would show emg activity since they are being stressed.The counter clockwise torque of the hip will try to topple the body.
Also there would be a stress in the muscles below the knees which will also show emg activity.
