Chapter 1: Intro to Kinesiology 01/20/2016 ▯ What is Physical Activity? ▯ -Almost any muscular action is physical activity ▯ -By definition, it is intentional, voluntary, movement directed towards achieving an identifiable goal. ▯ Movement- any change in the position of your body parts relative to each other ▯ ▯ -All physical activity is movement but not all movement is physical activity. ▯ ▯ What is Kinesiology? ▯ -A discipline or body of knowledge that focuses on physical activity. ▯ Consists of: ▯ -Experiential knowledge= experiencing physical activity ▯ -Theoretical knowledge= systematic research about physical activity ▯ -Professional practice knowledge= process of delivering physical activity services ▯ ▯ The Focus of Kinesiology: Exercise and Skilled Movement ▯ -Exercise is one principal form of physical activity. ▯ -People engage in exercise to improve physical performance, improve health, or regain performance that has been reduced due to injury/disease ▯ ▯ Major Categories of Exercise: ▯ Training- exercise performed for express purpose of improving performance ▯ Health-related exercise- to develop or maintain a sound working body, free of disease ▯ Therapeutic exercise- to restore capacities previously developed that have been lost due to injury, disease, etc. ▯ ▯ Skilled Movement ▯ -Second area of focus of kinesiology ▯ -Performances where accuracy of direction, force, rhythm, and timing are essential to accomplishing predetermined goals ▯ -Sport involves skilled movement that is organized in game contexts. ▯ -Developmental skills involve skilled movements that aren’t usually performed in sport settings. ▯ Ex. 1 graders being taught how to skip, hop, or throw ▯ ▯ Holism- interdependence of mind, body, and spirit ▯ ▯ Spheres of Physical Activity Experience ▯ -Competition -Self-sufficiency ▯ -Health -Work ▯ -Leisure -Self-expression ▯ -Education ▯ ▯ Spheres of Scholarly Study of Physical Activity ▯ -Biomechanics -Philosophy of physical activity ▯ -Motor behavior -Physiology of physical activity ▯ -Sociology of physical activity -Sport and exercise psychology ▯ -History of physical activity ▯ ▯ Spheres of Professional Practice Centered in Physical Activity ▯ -Health and fitness -Therapeutic exercise ▯ -Sport management ▯ -Coaching and sport education ▯ Teaching physical education ▯ ▯ ▯ ▯ ▯ Clicker Questions: -Philosophers take intangibles seriously; these include emotions, ideals, values, and daily experiences. -Materialism: this view reflects the belief that subjective experiences are of little value an that humans are complex machines -Deductive reasoning starts with broad, general principle and examines specific facts that follow from it. True -A comparison of play-like sport to duty-like sport finds that play-like sport considers: sport participation justified by its intrinsic value Objectives -Philosophy involves asking questions posing challenges searching for deeper meanings. -Describe how Philosophy is a formal field/sub-discipline of Kinesiology Why should we study Philosophy? -The definition of philosophy is the study of wisdom, knowledge, and the truth. -Critical thinking us pull the “blinders” away from our eyes, break with conventional ideas and follow new ideas. -It helps develop well-reasoned arguments. -It can help us become more open minded. -it can makes us entertain, examine, and accept new ideas, theories, that might have been ignored of rejected. Philosophical Thinking in Physical Activity -Reflection is the key -Various types of reflection are used. -Decisions are based on good judgment and logic. -Valid and reliable results are expected (even without controlled experiments as in the physical sciences). Power of Reflection -Allows for a broader range of phenomenon to be studied. -Forces us to examine our own beliefs in greater depth and to develop well- reasoned arguments for them. -Helps us become more open-minded: We entertain, examine, and possibly accept ideas, theories, and positions we may have previously ignored or discarded without good reason. Reflection -Tools -Logic -Speculation -Imagination -Thinking -Philosophic methods typically do not include the gathering of data from controlled experiments, but the results can still be valid and reliable. Philosophic Claims About Values in Physical Activity -Personal opinion -Speculation -Probable assertion Truth assertion Goals of Philosophy of Physical Activity in Kinesiology 1. To understand the nature and value of health and physical activity, particularly in the form of exercise, sport, games, play, and dance 2. To understand how confident we can be about our claims in kinesiology 3. To understand the most important values of physical activity and its contribution to good living 4. To learn how we ought to behave in sport and in our professional lives as kinesiologists Research Methods -Inductive reasoning begins with specific cases to develop broad, general principles. -Deductive reasoning begins with broad factual or hypothetical premises in order to determine more specific conclusions that follow from them. -Descriptive reasoning begins with one example of some phenomenon and then varies it to see how dramatically it changes. Change allows a more accurate description of the central characteristics of the item being examined. Overview of Knowledge in the Philosophy of Physical Activity -Nature of the person (specifically, the mind-body relationship) -Nature of the sport and competition and its relationships to work and play -Values promoted by physical activity -Ethical values and sport People are composed of two substances: BODY and MIND -Materialism: the human being is nothing more than a complex machine; subjective experiences are real but have no power -Dualism: the mind and body are separate; our thoughts count; priority is given to the mind -Holism: the mind and body are interdependent; all behavior is ambiguous; the mind and body work together Significance of Rules -Rules serve as formal types of game cues: What should be accomplished and how we should accomplish it? -Rules create a problem that is artificial yet intelligible -Respecting the rules preserves sport -Rules liberate us and allow us to explore our capabilities in a protected environment -Rules can be change when the challenge becomes too easy or too difficult Game Characteristics -Mild Physical Exertion -Limited skill -Luck -Recreational activity -Some rules – change them? -Enjoyment or Entertainment -A game may not be a sport Hobbies & Competition Hobbies: -Activity or interest -Done outside one’s regular job -For fun -For pleasure Competition: -Requires two parties, but not necessarily against each other -Can be done by yourself -Surpassing a performance -It can determine winners and losers Play and Duty in Sport Duty-Like Sport: -We participate for the benefits, we do it for what it does for us. Play-Like Sport Health Related Physical Fitness Four Components -Body composition -Flexibility -Cardio -Muscular strength Motor Skills -Balance -Hand/Eye Coordination Do we as Professionals have Responsibilities? -The National Strength and Conditioning Association (NSCA) 1. Non-Discriminate: on the basis of race, color, sex, age, religion, or national origin 2. What type of conduct? -Personally and professionally in a manner that does not compromise their professional responsibility 3. Truthful in what? -Education and Experience Professional Knowledge and Expertise -Kickboxing class Physical Activity Values -Ethical -Aesthetic -Sociopolitical Ethics -Ask us what is right and wrong, and what ought and ought not be done -Help us answer the question “How should we behave?” Examples: -Should children be cut when trying out for a sport? -Should a coach teach an athlete how to intimidate the opponent player? Should an athlete be required to pass all school subjects in order to play? Ethical Behavior in Sport -Fair play: playing within the rules -Seeking to win within the rules and not “at all costs” -Opponents should be treated with respect -Games are played as mutual quests for excellence, is intimidation inappropriate? -Retribution for violent or unfair action is never acceptable Clicker Questions -Intercollegiate athletics were inaugurated on American college campuses by: students -According to Dr. Grimsley ECU student were mainly women.
