Science of Motion Captuer

Motion Capture Definition: Recording of motion for immediate or delayed analysis and playback. Developed to record animal and human locomotion. - Still photography - Video to High speed - Motion capture marker systems. 2D STANDARD VIDEO: PAL 50 hz (25 frames per second) NTSC 60 hz (30 frames per second) Standard video limitations: - capturing of fast or critical events in movement often...

Projectile Motion

Projectile Motion: Projectile motion: form of linear kinematics (curvilinear), shows changes in velocity and acceleration are going to occur once the object leaves the ground, hand, foot etc. Linear motion that here are X & Y components, vertical and horizontal components. Gravity: Gravity results in constant vertical acceleration...

Angular Kinematics

Angular Kinematics Describing angular motion or displacement? Angular Distance and Displacement: Units of measurement: radians (1 rad=57,3 degrees), degree, revolutions (revs) Angular Velocity ( w ) - Time rate of change of angular displacement (rad/s, deg/s, rev/s) Linear velocity = change in displacement over time. Angular velocity...

Muscles of the Foot and Ankle

Dorsal Venous arch: Gives rise to saphenous vein medially and gives rise to lesser saphenous vein laterally. The saphenous vein is located in front of the medial malleoli. Deep Fascia of the dorsum of the Foot Deep Fascia of the dorsum of the foot is continuous with the fascia cruris via extensor retinacula. Deep fascia blends in with the...

Anatomy of Foot and Ankle

Tibial Tuberosity:  Important for tendons and a useful surface landmark. Head of Fibula: Easily palpated because of the subcutaneous on the posterolateral aspect of the knee. Division of the common peroneal nerve occurs here. Lateral Malleolus:  Medial Malleolus:  Calcaneus: Styloid Process: can be palpated in the...
