OBJECTIVES • Define the terms biomechanics, static, dynamics, kinematics, and kinetics and explain the ways in which they are related.
Introduction What is Biomechanics?
bio mechanics What is biomechanics? Application of mechanicalprinciples in the study of living organisms
Sub-branches of biomechanics: • Statics • study of systems in constant motion • including zero motion • Dynamics • study of systems subject to acceleration
Sub-branches of biomechanics: • kinematics: study of the appearance or description of motion • kinetics: study of the actions of forces
What is kinesiology? the study of human movement
Kinesiology Biomechanics Adapted physical education Exercise physiology Motor behavior Athletic training Sport history Pedagogy Sport philosophy Sport art Sport psychology Kinesiology
Sports Medicine an umbrella term that encompasses both clinical and scientificaspects of exercise and sport
Sports Medicine Biomechanics Athletic training Exercise physiology Physical therapy Cardiac rehabilitation Motor control Sport nutrition Sport psychology Athletic training Other medical specialties Sports Medicine
Qualitative vs. Quantitative: • qualitative: pertaining to quality (without the use of numbers) • quantitative:involvingnumbers
Solving Formal Quantitative Problems: • Read the problem carefully. • List the given information. • Write down what quantity is to be solved for. • Draw a diagram of the problem situation
Solving Formal Quantitative Problems: • Select the appropriate formulato use. • Review the problem statement to determine if more information can be inferred. • Substitute the given information into the formula.
Solving Formal Quantitative Problems: • Solve the equation for the unknown variable. • Do a “common sense” check of the answer. • Box in your answer, including the correct units of measurement.
History of Biomechanics • Aristotle (384-322 BC) • Father of Kinesiology • Leonardo da Vinci (1452-1519) • Modeled muscles • Considered the body as separate segments • Galileo Galilei (1564-1642) • “Nature is written in mathematical symbols” • Applied mechanics to animal movement • Alfonso Giovanni Borelli (1608-1679) • Synthesized the ideas of da Vinci and Galileo • Applied the laws of mechanics and mathematics to muscular performance
Select Historical Contributors Etienne Marey (1830-1904) Eadweard Muybridge (1830-1904)
So, why study Biomechanics? ApplicationExercise and Sports Sciences • Performance enhancement • Injury prevention and rehabilitation • 2.Athletic competition • Exercise / training / recreational sports • Activities of daily living
ApplicationPerformance Enhancement • Pitching analysis • Individualized sport technique • Application of soccer style technique in football place kicking • Balance assessment for fall prediction in elderly • Ergonomic work place design
ApplicationInjury Prevention and Rehabilitation • Biomechanics of the knee joint following ACL surgery • Sport shoes and their role in motion control and shock absorption • Landing mechanics indicative of a female predisposition to ACL injury • Examination of the role of soft tissue motion on joint loading and injury • Heading and head injury in youth soccer
