Kinesiology: Definition • the discipline concerned with the comprehensive and systematic study of human movement • What is the purpose of kinesiology?

Kinesiology: Purpose • To describe, explain, and predict how and why people move for the purpose of • Performance enhancement • Injury prevention • Risk reduction for chronic disease • Social and aesthetic enjoyment Technique Equipment Training

Kinesiology: Purpose • Performance enhancement  the best performance that one can achieve given the constraints (or limitations) acting on the system safety  effectiveness  efficiency

What is a profession? • A body whose chief aim is to improve the conditions of society by providing a regulated service in which practices and educational/training programs are developed that are in accordance with knowledge available from one or more relevant disciplines

Rehabilitation Physical therapists Occupational therapists Massage therapists Orthopaedists Cardiologists Cardiac & Pulmonary Rehabilitation Athletic trainers Performance Strength & Conditioning Coaches Athletic Coaches Musicians Actors Dancers Athletes Kinesiology: Professions

Injury Prevention Physical education teachers Personal trainers Ergonomists Exercise specialists Massage therapists Athletic trainers Kinesiology: Professions

So… • Why do you have to take this course? • How does this course fit into the study of kinesiology?

Subdisciplines

The Subdiscipline of Functional Human Anatomy • Subdiscipline of kinesiology concerned with understanding • the contributions of the muscular and skeletal systems to human movement • the acute and chronic effects of activity on the musculoskeletal system • Focus is at the tissue, organ,organ system, and organism level

Also draws from biomechanics

Mechanics • Branch of physics that is concerned with the motion and deformation of particles and mechanical systems that are acted on by mechanical disturbances called forces

Biomechanics • The science that examines forces acting upon and within a biological structure and effects produced by such forces • The science that applies the principles of mechanics to the conception, design, development, and analysis of equipment and systems in biology

Branches of Mechanics

Physical Quantities • Base quantity – defined in terms of a standard • Derived quantity – defined in terms of one or more base quantities • Units for quantities determined by system used • SI system (Systeme International – MKS system) • British system • CGS system

Base Quantity Unit Unit Abbreviation length meter m time second s mass kilogram kg electric current ampere A temperature kelvin K amount of substance mole mol luminous intensity candela cd plane angle degrees o SI Base Quantities & Units length (m) – the length of path traveled by light in a vaccuum during a time interval of 1/299,792,458 of a second British system: Length – foot Time – second Mass – slug

So… • How does this course fit into the study of kinesiology?

You will… • be able to answer, in part, the following questions: • What causes movement? • How can a movement be changed to improve performance and/or prevent injury? • learn the language of kinesiology and gain basic knowledge about movement causes and outcomes. • develop observation, analytical, and evaluative skills necessary for analyzing human movement.

Course Objectives • Explain the roles that the subdisciplines of functional anatomy and biomechanics play in the study of human movement. • Demonstrate knowledge of how skeletal and muscular architecture and function interact to create forces and torques that contribute to injury and human movement performance.

Course Objectives • Demonstrate knowledge of how the human body and the external environment interact to create the forces and torques necessary that contribute to human performance and musculoskeletal injury. • Identify structural and mechanical factors that limit successful performance in human movement activities.

Course Objectives • Perform a systematic qualitative anatomical analysis of human movement activities or skills in sport, dance, exercise, rehabilitation, work, and daily living.
