Kinesiology 355 (Science, Sport, and Fitness) is designed to provide an academic environment where students can explore some basic issues regarding their biological and physical environments that directly effect there physical fitness, health, and movement performances. This is accomplished through a systematic process of introducing an issue of human performance, identifying basic science issues associated with that aspect of human performance, and demonstrating the connections between both. Then the student is lead through a series of lectures and readings on the relevant topics emphasizing how fitness, health, and movement performance is impacted by the degree by which the quality and quantity of the basic science issue functions in the persons. An understanding of the interrelationships between human performance and basic science issues allows the student to better appreciate how the functional capacities of the human body are regulated by the laws of science which are, in turn, impacted by the internal and external environment of the individual. It follows, then, that several aspects of our modern society, both local and global, can place stresses of both positive and negative natures on those environments. Therefore, the Kinesiology 355 topics include the coverage of issues such as pollution, disease/health, hypokinesis, energy transfer, nutrition, lifestyle, ageing, and technology, and how those issues impact one's functional capacities over the lifespan.
