A person is sitting on a stage edge with their knee at 90 degrees (flexion). They lower the leg to 10 degrees and holds in this position?
what major muscle group is the agonist? What kind of muscle contraction happens by the agonist? Is it open or closed chain?
does the type of contraction change if you add on weight?

A person is doing leg flexion/extension exercises from a sitting
position in order to strengthen the person's quadracept muscles.
The forces acting in the lower leg are illustrated in the figures
below.
W0 is the weight of the boot, W1 = 160 N
is the weight of the person's lower leg, FM is the
magnitude of the force exerted by the quadricepts muscle on the
tibia (shinbone) through the patellar tendon, and FJ is
the force due to the tibiofemoral...

John sitting on a table performs knee extensions with his right leg hanging over the edge and a 12 kg weight attached to the right ankle. The mass of his right shank is 4 kg and the length of the shank is 0.47 m. The moment arm of the quadriceps is 0.05 m and the center of gravity of the shank is in the middle. When the knee is fully extended (i.e. the shank is horizontal), what is the muscle...

A person is sitting with one leg outstretched and stationary, so that it makes an angle of 30.0° with the horizontal, as the drawing indicates. The weight of the leg below the knee is 45.0 N, with the center of gravity located below the knee joint. The leg is being held in this position because of the force M applied by the quadriceps muscle, which is attached 0.100 m below the knee joint (see the drawing). Obtain the magnitude of...

PROBLEM 2 Knee Extension - The angular motion of the lower leg about the knee joint, and the forces and torques produced by the muscles crossing the knee joint during knee flexions and extensions have been investigated by a number of researchers utilizing different experimental techniques. One of these techniques is discussed here. Consider the person illustrated in Fig. 10.12. The test subject is sitting on a table, with the back placed against a back rest and the lower legs...

Musculoskeletal Nursing Which of the following nursing interventions is appropriate care for a client who is two days post op with a below the knee amputation of the left leg? Wrap the stump only at night so the suture line is open to air during the day. Encourage the patient to lie only on their back and unoperative side. Elevate the foot of the bed slightly to decrease edema. Elevate the stump on pillows to prevent contractures. The nurse is...
