Notes on Chapter 1–2: Introduction to Kinesiology and The Physical Activity Experience
Chapter 1: Introduction to Kinesiology
Motivation and scope
People engage in televised games, athletic dress, and social rituals around sports; motivation and passion for physical activity are powerful and not fully explained.
The attraction to running, golfing, tennis, etc., can be analyzed through motivation and identity in physical activity.
Passion for physical activity is foundational to kinesiology, the academic study of physical activity.
Physical activity experience is ubiquitous and often taken for granted, yet it underpins kinesiology as a discipline.
What is kinesiology?
Defined as the academic study of physical activity and its impact on health, society, and quality of life.
Kinesiology focuses on human movement performed intentionally to achieve goals.
The discipline is organized around three knowledge sources:
Physical activity experience
Scholarship of physical activity
Professional experience in physical activity
These three sources are integrated in curricula and research to form the official body of knowledge in kinesiology.
Three sources of knowledge about physical activity (Figure reference: 1.2)
1) Physical activity experience: learning by doing (watching, performing, and participating in activities).
2) Scholarship of physical activity: theoretical and practical study, including modeling, experiments, lab work, reporting, and peer review.
3) Professional experience in physical activity: designing and implementing activity programs for clients in professional practice (e.g., athletic trainers, physical education teachers).
These sources are embedded in college curricula and consensus research to constitute the discipline.
Why kinesiology? Growth and career scope
Increasing enrollment in kinesiology programs—one of the fastest-growing majors in higher education; departments often large on campuses.
Growth driven by: (a) expansion of physical activity–related professions, (b) greater appreciation of physical activity’s health and lifespan relevance.
Before the 1990s, many kinesiology departments focused on physical education teachers and coaches; now they underpin diverse careers.
Careers include: physical education teaching, coaching, physical therapy, cardiac rehabilitation, sport management, athletic training, fitness leadership, public health, sports performance, and more.
Graduate pathways: master’s and doctoral study for advanced practice or research; increasingly, master’s degrees are required for many allied health professions (e.g., athletic training programs moved to graduate level in 2023 for certification eligibility).
Discipline, definition, and scope
A discipline is a body of knowledge organized around a theme; kinesiology centers on human physical activity.
The discipline is interdisciplinary, integrating biological, medical, health, psychological, social-humanistic, and professional perspectives.
AKA (American Kinesiology Association) defines kinesiology as the academic discipline studying physical activity and its health, societal, and quality-of-life impacts (2021).
The discipline embraces and integrates multiple perspectives; historical terms like physical education are evolving into kinesiology in many universities.
The focus of kinesiology: physical activity
Physical activity is not simply any movement; it is intentional, voluntary movement directed toward an identifiable goal.
Movement is a necessary but not sufficient condition for physical activity.
Movement alone, without goal-directed intent, does not meet the technical definition of physical activity.
Three key aspects of Newell’s formulation (1990):
Movement can be energy-intensive (e.g., running) or low-energy (e.g., typing); energy expenditure is not a prerequisite for physical activity.
The setting of the activity is irrelevant; physical activity occurs in diverse environments.
Movement must be intentional and directed toward a goal to count as physical activity.
Distinction clarified: movement = change in body position; physical activity = intentional, goal-directed movement.
The relationship between movement and physical activity: Movement is necessary but not sufficient for physical activity.
Sherrington’s notion: “All [humans] can do is to move things,” prompting reflection on the role of movement in life.
The discipline’s organization and scope (Holism and interdisciplinarity)
Kinesiology is holistic, integrating mind, body, and spirit; not just a mechanistic view of the body.
The field includes anatomy, physiology, biomechanics, motor control, pedagogy, psychology, sociology, philosophy, and history.
The discipline spans multiple forms of physical activity: dance, exercise, fundamental movements, sport, and therapy.
Subdisciplines may connect with parent disciplines (e.g., exercise physiology from physiology; motor behavior from psychology; philosophy of physical activity from philosophy).
The AKA core curriculum elements (four core areas)
(1) The importance of physical activity to health, wellness, and quality of life
(2) Scientific foundations of physical activity
(3) Cultural, historical, and philosophical dimensions of physical activity
(4) The practice of physical activity
These core elements guide undergraduate programs and ensure a comprehensive education in kinesiology.
Components of physical activity and examples of forms
Dance: expressive movement often tied to music; combines art and science of movement.
Exercise: programmed activity aimed at improving movement function, health, and aesthetics; includes several subtypes:
Training: exercise to improve athletic, military, work-related, or recreation performance; relevant for strength and conditioning careers (CSCS certification, NSCA).
Health-related exercise: to develop/maintain health and longevity; primary focus for fitness leaders and personal trainers.
Cosmetic exercise: training to reshape body for aesthetic reasons; motivations may be health- or appearance-driven; important to understand client motivations.
Fundamental movements: basic movement patterns (carrying, catching, jumping, kicking, running, throwing, walking) that underlie more complex skills.
Sport: skilled movement in game contexts with rules and competition; emphasizes skill, rules, competition, and sometimes not requiring specific energy expenditures.
Therapy: therapeutic exercise to restore or develop abilities lost due to injury, disease, or aging; may involve rehabilitation specializations.
The professional landscape and interdisciplinary nature
Kinesiology students develop working knowledge of multiple disciplines and apply them to physical activity.
Subdisciplines often relate to broader fields (psychology, physiology, sociology, biology, history, philosophy).
Allied fields connection: public health, dance, recreation; professional organizations historically linked but now more specialized (SHAPE America, physical education, etc.).
The field’s holistic mission includes health-promotion, prevention, rehabilitation, and performance.
The field’s organizational breadth and variability in departmental naming
AKA-supported model emphasizes kinesiology as the umbrella term; many universities use different departmental names (e.g., exercise and sport science, health and kinesiology, human movement science).
The name reflects institutional mission and organizational structure; the field is still evolving and sometimes controversial in naming across institutions.
Evidence-based practice in kinesiology
Licensure and certification in many kinesiology-related professions rely on evidence-based practice (EBP).
EBP blends: scientific research, professional/clinical experience, and client values/preferences.
The book uses “three-dimensional knowledge” to align with EBP models; later chapters expand on professionalism and EBP (Chapters 10–15).
Knowledge sources and professional practice examples
RugbySmart (New Zealand): a national program using a 10-point strategy to reduce rugby injuries; reduced serious spinal injuries; spawned other Smart programs across sports (Quarrie et al., 2007, 2020).
Ethical, equality, and expertise considerations in kinesiology practice are emphasized across chapters.
Professional and ethical considerations in kinesiology
Emphasis on equality, evidence-based practice, and expertise as core professional principles.
APA and AMA citation styles commonly used in kinesiology publications; cross-disciplinary literacy is important.

Chapter 2: Importance of the Physical Activity Experience
Chapter focus and objectives
Explore the diversity and pervasiveness of physical activity in social settings (spheres).
Introduce physical activity as a human signature and discuss benefits and limitations.
Consider factors influencing people’s perceptions and decisions to engage in physical activity.
Preview how to prescribe physical activity experiences, considering spheres and personal factors.
The experience of physical activity: two domains
Direct experience: training, observation, and personal participation in physical activity.
Inward, subjective experience: individual reactions, feelings, memories, and meanings derived from physical activity.
Both domains shape capacity to perform, learn, and promote activity in others.
Seven spheres of physical activity experience (Figure in part I opener)
Self-sufficiency
Self-expression
Work
Education
Leisure
Health
Competition
These spheres represent contexts in which physical activity serves distinct purposes and can involve different professionals.
Important clarifications:
Spheres are not mutually exclusive categories; activities can span multiple spheres.
The framework helps analyze how everyday life integrates physical activity.
Sphere highlights and professional roles
Self-sufficiency: ADLs and IADLs; therapists (OT/PT) help regain daily living abilities; IADLs are more physically demanding than ADLs.
Self-expression: using movement to convey feelings; gestures, dance, posture; though expressive movement is meaningful, not all such movements meet the technical definition of physical activity.
Work: evolving with technology; physical activity in work settings; ergonomics and human factors reduce injury risk; the future trend toward more sedentary work.
Education: physical activity instruction within sport, exercise, and physical education; the universal role of education in shaping activity patterns; PE as near-universal but evolving.
Leisure: leisure as a state of being, not just free time; distinction between leisure and hollow free-time activities; activity types and their relation to leisure dispositions.
Health: health benefits of regular, moderate physical activity; the value of professionally designed programs; health-related fitness vs motor performance fitness; hypokinetic diseases.
Competition: competition as an organizing principle that can enhance performance and enjoyment; cooperation among participants is essential to maintain the activity; healthy competition vs cheating/spoiling the game.
Key points about the spheres
Spheres illustrate the diverse purposes of physical activity and related professional practice.
They help frame how to prescribe and analyze experiences across contexts.
Spheres are best understood as dimensions, not rigid categories; activities may cross spheres (e.g., running can be leisure and health).
Experience and skill development: learning vs training
Two primary forms of experience influence improvement:
Skill development through practice (learning, motor skill acquisition).
Physical conditioning through training (capacity development: strength, endurance, flexibility).
Figure 2.4 concept: experiences contribute to both skill and capacity; the balance depends on the activity and context.
Learning and cognitive processing are central to early skill development; practice involves feedback, strategy, and gradual refinement.
Deliberate practice (Ericsson et al., 1993): tailored activities to improve performance; often cited as central to expertise, but meta-analyses show the explained variance is smaller than popularly believed.
Macnamara, Hambrick, Oswald (2014): deliberate practice accounts for about 1–26% of variance in motor performance, with ~18% in sports overall; higher for lower-skilled individuals (about 19%), and much lower for elite athletes (about 1%).
Learning vs training and the role of cognition
Early learning is cognitively demanding; later performance can become implicit or automatic.
Neural remapping in the CNS underlies motor learning; practice reshapes neural pathways, not just muscles.
The concept of “muscle memory” is a misnomer; changes occur in the brain/spinal pathways.
The extent and permanence of motor skill improvements depend on continued practice and the physical capacity to perform the skill.
Heredity vs experience in performance
Elite performance arises from a combination of genetics and practice; heredity contributes to initial potential and trainability, but practice and training shape outcomes significantly.
Subjective experience of physical activity
Indoor experiences (emotions, memories, meanings) are critical; subjective experience can motivate continued participation.
The internal experience (joy, challenge, fatigue) interacts with external skill and conditioning to shape engagement.
Philosophical and ethical considerations arise in how we understand and promote meaningful activity in others.
Overload and perceptual experience in training
Overload principle: training intensity must exceed current fitness to stimulate adaptation; balance is needed to avoid overtraining.
Perceived exertion and physiological load can diverge in some activities (e.g., water-based activities require careful monitoring).
Practical implications for prescribing activity
Exercise programs should consider skill development and conditioning, maximizing meaningful, enjoyable experiences to sustain activity.
Individual differences in social environment and personal circumstances influence activity choices and persistence.
Social and personal factors influencing activity (contexts and environments)
Social environment: peer influence, parental modeling, coaches and teachers can strongly shape activity patterns in youth.
Parents influence: role modeling and support affect activity, but direct correlations between parent and child activity levels are not always strong; sedentary behaviors in parents predict sedentary behaviors in children.
Peers: peer activity levels influence individual activity; social networks can encourage or discourage participation.
Personal circumstances: geography, climate, culture, equipment cost, and access influence participation.
Technology and modern life: long commutes and sedentary work patterns reduce incidental activity; workplace interventions (ergonomic desks, active desks) help integrate movement into daily life.
Practical health and safety considerations in work and life
Ergonomists/human factors engineers apply anatomy, biomechanics, and psychology to reduce injury risk and improve efficiency in the workplace.
Musculoskeletal injuries and overexertion are significant concerns; female workers are particularly susceptible to certain repetitive-motion injuries.
The balance between health benefits and overtraining risks is important in planning activity programs (e.g., risk of long-term issues in high-volume endurance athletes).
Health and public interest in physical activity
Public health economics: healthier populations reduce health care costs; U.S. health care spending reached about 4{,}000{,}000{,}000{,}000 dollars in 2020 and is projected to exceed 6{,}000{,}000{,}000{,}000 by 2028.
Evidence supports supervised, well-designed programs to maximize health outcomes and reduce disease risk.
Education and sport instruction in society
Sport and exercise instruction now occurs in diverse settings beyond schools: gyms, hospitals, private clubs, camps, corporations, media-based instruction (e.g., Golf Channel Academy).
Physical education remains central to many curricula as a universal means of teaching sport, exercise, and movement fundamentals; quality PE is crucial for youth development.
National standards and curricular guidance (chapter 13) influence instruction quality and outcomes.
Leisure, health, and quality of life
Leisure is not merely free time; it is a state of being that nourishes culture and personal well-being.
Leisure activities should be meaningful and stimulating, not merely filler activities (e.g., mindless TV).
Leisure, health, and competition intersect in ways that shape public interest and personal motivation to remain physically active.
Competition and sport philosophy
Competition is an organizing principle that can elevate performance but must be fair and cooperative to maintain integrity.
Sport philosophy emphasizes mutual striving for excellence and intelligent use of skills in the face of challenge; cheating and spoilsport behavior undermine the activity.
Evidence-based practice and professionalism in Chapter 2
The chapter connects theory to practice by emphasizing EBP in kinesiology careers and research-informed decision making.
It introduces three essential professional issues: equality, evidence-based practice, and expertise, to be considered in all professional actions.

Additional notes on LaTeX-formatted items used in this course
Newell’s definition (conceptual): ext{Physical Activity} = ext{intentional} \land \text{voluntary} \land \text{goal-directed movement}
Deliberate practice variance: 1\% \le p \le 26\% of variance in motor performance; sports-specific: \approx 18\% overall; higher for lower-skilled groups (≈19\%) and lower for elite (≈1\%).
Health expenditure figures (illustrative): public health costs rising toward 4\times 10^{12} (approx. $4{,}000{,}000{,}000{,}000$) dollars in 2020, projected to exceed 6\times 10^{12} by 2028.
Population statistics and organizational counts (illustrative): more than 170 kinesiology departments in U.S. colleges and universities; master’s-level entry in athletic training programs as of 2023 for certification eligibility.
Cross-cutting themes to remember
Kinesiology is a holistic, interdisciplinary field that studies physical activity across multiple spheres of life.
Knowledge is built from experience, scholarship, and professional practice, integrated through education and evidence-based practice.
The seven spheres provide a practical framework for understanding how physical activity touches all aspects of human life and how professionals can tailor experiences to individuals and communities.
The field continuously evolves in terminology, scope, and professional practice, but the core aim remains: understanding and promoting meaningful, safe, and effective physical activity for health, learning, and quality of life.
Suggested connections to real-world practice
In planning fitness programs, consider clients’ goals, capabilities, and subjective experiences; integrate skill development (practice) with conditioning (training) for balanced improvements.
In workplace design, apply ergonomics to reduce injury risk and improve productivity, recognizing changing work patterns and new technologies.
In education, ensure PE and sport instruction emphasizes both skill development and health benefits, aligned with evidence-based standards.
Final reminder
The discipline of kinesiology is not just about exercise and sport; it encompasses the whole spectrum of human movement and its meaning in everyday life, health, and society.
Kinesiology is the academic study of physical activity, defined as intentional, voluntary, goal-directed human movement. It is a holistic and interdisciplinary field, drawing knowledge from three main sources: physical activity experience (learning by doing), scholarship of physical activity (theoretical study), and professional experience (applying knowledge in practice). The discipline has seen rapid growth due to expanding career opportunities in diverse fields like physical therapy, sport management, and public health, and a greater appreciation for physical activity's health benefits.
Kinesiology organizes physical activity into seven spheres of experience: self-sufficiency, self-expression, work, education, leisure, health, and competition. These spheres highlight the diverse purposes of physical activity and the contexts in which kinesiologists work. Improvement in physical activity involves both skill development through practice (learning) and physical conditioning through training (capacity development). While genetics contribute to potential, diligent practice is crucial for performance. Subjective experiences
(emotions, memories) are vital for motivating continued participation. Evidence-based practice, integrating scientific research, professional experience, and client values, is central to effective kinesiology practice.
