Document Summary
**measures of error are the most important to study from lecture 3** Variable error target? you miss the cup. Human movements organized by external and internal forces. Importance of force: all three of newton"s laws of motion refer to force, angular force = torque this is what we will use when we discuss measurements. All of human movement is organized by external forces. At the same time internal forces are present. Electromyography (emg: recording of muscle electrical activity. Common use is to determine when a muscle begins and ends activation [see figure 2. 10] Stabilizer muscles to help you remain upright instead of falling forward . Figure 2. 10 shows if we measure activity of hamstrings, the very first muscle to be active when you want to lift your hand up is the hamstrings to pull you backward and keep you centre. Whole muscle mechanomyography (wmmg: displacement of muscle belly after stimulation.
