In the picture below, an individual performs a squat from a more upright position (A) to a squatted position (B). The segment lengths are: Trunk = 78cm, Thigh = 68cm, Leg = 66cm, Foot = 42cm. Answer the following three questions (5pts). Distance Between Joints Shoulder to Knee = 119.7cm Hip to Ankle = 96.4cm shoulder Distance Between Joints Shoulder to Knee = 82.1cm Hip to Ankle = 74.6cm shoulder Trunk Trunk hip hip ( Ꮎ Thigh > knee Thigh...

Leigh is doing a knee extension exercise using a 100 N weight strapped to her ankle 40 cm from her knee joint. She holds her leg so that the horizontal distance from her knee joint to the weight is 30 cm. 1) What is the moment arm of the weight about the knee joint axis? 2) For this position, what torque is created by the ankle weight about her knee joint axis? 3) If the moment arm of the knee...

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...

KIN 3112 Homework #3 Perform a dynamic analysis for a knee extension movement. The knee extensors insert on the tibia at an angle 0-30° and at a distance d-5.2 cm from the axis of rotation of the knee. The combined weight of lower leg and foot is F 48 N and its center of mass is r 0.27 m away from the knee joint axis. The joint angle with respect to the left horizontal is A-70 (Note: this is not...

An athlete is planning performing some knee extension exercises. He sits on the end of a bench so that his legs dangle in the air. A mass was attached (25 kg) to their right ankle and then the right leg was held out straight (0 deg knee angle) and paused. If the length of their lower leg between the knee and ankle is 17 inches, and the moment arm of the quadriceps femoris is 20 mm. What is the force...

Provide an example of an athletic movement of the shoulder, hip, and knee joint (3 total movements). For each example provide the agonist and antagonist muscles. Furthermore, explain what part of the movement the concentric or eccentric phase is. (15 points) Supinated Biceps Curl Example: Agonist: Elbow flexors (Biceps) Antagonist: Elbow extensors (Triceps). The lowering phase of the biceps is the eccentric phase and the upward phase is the concentric phase.

4 . 5 . . . . . . 7 . The patient is having pain around the medial aspect of his left knee. About 12 years ago he had a tear of his medial meniscus (crescent-shaped fibrocartilage), which was removed. Onexamination, he has a well-healed medial scar to his left knee; there was no effusion; full range of motion; and it is stable. X-rays show very slight scarring of the medial femoral condyle and a small accessory bone medially,...

As Jennifer runs, her knee joint passes through the following vertical positions (meters): Frame 1: 0.091 Frame 2: 0.151 Frame 3: 0.284 Frame 4: 0.320 Frame 5: 0.490 The data were collected at a frequency of 100Hz (i.e. 100 frames per second). What was the vertical acceleration of her knee joint at the third time point. Round your answer to the nearest tenth (i.e. 1 decimal place) and DO NOT include units.
