Mechanical linkage manages forces and movement through rigid links and ideal joints. Linkages can be open, closed, or combination of both. System mobility equals 6n degrees of freedom for n moving bodies
Jumping propels organisms through air along ballistic trajectories. Force against substrate generates reactive force for propulsion. Maximum horizontal distance occurs at 45° launch angle. Human optimal takeoff angle is ~23-26°
EMG evaluates and records electrical activity of skeletal muscles. Electromyograph detects electric potentials generated by muscle cells. Two main types: surface EMG for non-medical use and intramuscular EMG for medical diagnosis
