What is biomechanics? Chapter 1 bio mechanics What is Biomechanics? Application of mechanical principles in the study of living organisms 2 Major Sub-branches of Further Subdivisions of Biomechanics: Biomechanics • kinematics: study of the appearance • statics: study of systems in constant or description of motion motion, (including zero motion) - includes pattern and movement speed - coordination of sequencing • dynamics: study of systems subject to acceleration • kinetics: study of the actions of forces associated with motion Anthropometric Factors What is kinesiology? effect the kinetic forces required to produce movement • Size • Shape the study of human movement • Weight Related to the dimensions and weights of the body segments 1 KINESIOLOGY What is sports medicine? Adapted physical Biomechanics education an umbrella term that encompasses Exercise Motor behavior Athletic training physiology both clinical and scientific aspects of exercise and sport Sport history Pedagogy Sport philosophy Sport art Sport psychology Carpal Tunnel Syndrome Sports Medicine • Neurological wrist impairment Biomechanics Athletic training • Overuse injury • Caused by compression of the median Exercise Cardiac physiology Physical therapy rehabilitation nerve in the carpal tunnel • Symptoms in the hand include Motor control Sport nutrition – Numbness – Tingling Other medical Sport psychology Athletic training specialties – Pain Solving Formal Quantitative Problems: Qualitative vs. Quantitative: 1. Read the problem carefully • qualitative: pertaining to quality 2. List the given information (without the use of numbers) 3. Write down what quantity is to be solved for •Heavy/Light 4. Draw a diagram of the problem 5. Select the appropriate formula to use •Long/Short 6. Determine if more information can be inferred •Flexed/Extended 7. Substitute the given information into the formula • quantitative: involving numbers 8. Solve the equation for the unknown variable •6 kg 9. Do a “common sense ” check •3 Meters 10. Box in your answer, including the correct units •90 Degrees 2.
