- for contact, Abigail Du Plessis can be reached at [email protected] or at Office No. 13
Part 1: Getting to Grips
- Basic topics include an introduction to Anatomy, Biomechanics, and Anthropometry, relevance to understanding human movement, development of measurement units, measurement in HKE, qualitative/quantitative data, kinematics/kinetics.
- Kinematic concepts and terminology include forms of motion, open vs. closed kinetic chain movements, standard reference terminology.
- Tissues of the musculoskeletal system include the skeletal, muscular, and nervous systems.
- Study the the types of forces, an introduction to load-tolerance, and types of muscle action like concentric, eccentric, and isometric relating to forces acting on the musculoskeletal system.
Readings and Resources
- Readings include "Hall - Basic biomechanics" covering chapters 1, 2, 4, 5 and 6.
- Use the Anatomy.TV resource for anatomy study.
Biophysical Domain
- Biophysics is the branch of biology applying methods of physics to study biological structures and processes.
- Primary focus is understanding internal and external forces acting on the human body.
Understanding the Biophysical Domain
- Sub-branches of study include Statics, Dynamics, Kinematics, and Kinetics.
- The subdivisions for Bio include Fluid Mechanics, Rigid Body Mechanics, Deformable Body Mechanics
- The subdivisions for Physical include Kinematics and Kinetics.
- Kinematics references the way you describe the nature of motion (Descriptive Analysis).
- Kinetics attempts to explain the causes of motion (Explanatory Analysis).
Problems Studied by Biomechanists
- Problems include those related to sports, such as running, skating and tackling safety.
- Also studied are shooting in netball, optimizing equipment and understanding biophysical differences between males and females.
- Men typically outperform women in athletic events
- Testosterone levels differ between males and females as they age.
- Swimming performance is similar between boys and girls until around 10-11 years of age, after which boys begin to outperform girls.
Kinematics vs. Kinetics
- There is quantitative and qualitative analysis.
- Kinematics analyze body motion, and kinetics look at its causes.
Measurement
- Measurements quantify kinematic effects or kinetic causes, clarify the units used.
- A unit is a standard amount by which a quantity is measured can be inherently arbitrary.
- Distance (m) and time (s) are fundamental units.
- Velocity (m.s-1) and Acceleration (m.s-2) are derived units.
