How does energy exchange contribute to efficient human movement? The energy exchange in a movement cycle can be expressed as follows for certain cases: E = Delta E_rho + Delta E + Delta E - Delta E Identify and explain each of the terms in Equation 3.1. Supply an equation for the calculation of each quantity. Identify the limitations of Equation 3.1. When does it not apply? Sketch a graph of energy versus time for which the equation would not return an appropriate energy exchange estimate. Given the data in Table 3.1 for the 1/2 HAT segment (Head and Torso) for a cycle of human gait, estimate the level of energy exchange tailing place. Figure 3.1 shows the graphical representation of this data (note the break in the Y-axis). Discuss whether this confirms or refutes the conclusions drawn in 3(c) (i), giving reasons to support your conclusions. Solution Energy can neither be created or destroyed. Energy can only be transfer from one form to another. When we take into consideration human beings, the complete system is too complex. A great deat of metabolic activities combined with nervous impulse signal together act inorder for the occurence of movement in human.Kinetic chain are the main reason for the occurence of human movement. Kinetic chain in other words can be defined as all systems of the body inter- linked together. Various systems like skeletal system, nervous system along with cardivascular system do the job together to transfer enerfy or work along the body to the extremities causing movement. Major example in this case is the conversion of chemical energy in food to work or thermal enrgy, futheron this converted energy is transferred to different body part for human movement..
