Define static biomechanics and an example
Examining of the bodies (human bodies or objects), masses and forces at rest or constantly moving Example: Walking, or sitting down resting
Define dynamic biomechanics and name an example
Investigates masses and forces on the body or objects when they are speeding up (accelerating) or slowing down (decelerating) Example: sprinting, punching, kicking, swimming
What are 2 benefits to athletes of biomechanics?
• To not get injured as easily • Ability to perform your best
Define clinical biomechanics and name an example
Focuses on improving the ability of an injured or disabled person to do daily activity, exercise, or physical activity Example: helping an elderly lady to walk normally after a total knee replacement. Put in their contacts, OT THINGS
Define sport biomechanics and name an example
Applies mechanics and physics to enhance sport performance through improving techniques or equipment Example: helping an athlete get a better sprinting form
Who is considered the father of biomechanics?
Giovanni Alphonso Borelli
What is linear motion?
Where all the points of the body are moving in the same direction at the same time at the same speed at the same distance
What is angular motion?
Where the points of your body rotate/spin around the central imagery line (the axis)
What is general motion?
Where linear and angular movements are combined
Are unique body types essential/give an edge based on an athletes sport? And give an example
YES THEY ARE Example: Better for running backs to be shorter and more stocky, big wingspan for basketball
What is the sagittal plane?
Where it divides the body into right and left halves
What is the frontal plane?
Divides the body into front and back
What is the transverse plane?
Cuts the body into upper and lower halves
What did aristotle focus on
He focused on you need a healthy body to have a healthy brain. And studied movement of the body as well.
What did Claudius Galen focus on
Studying gladiators (physician of the gladiators). How the body functions.
What was leonardo da vincis focus on in regards to biomechanics?
How the body works as a machine and how the parts work together
What was galileo galilei focus on in regards to biomechanics?
How the body is in motion
how did the 20th century influence biomechanics?
New industrial technology to exam the workers and how their biomechanics work
Define mechanical system and name an example
The system that you are interested and that you want to study EVERYTHING INVOLVED TO MAKE THE BODY MOVE OR BODY PART Example: the racket and the person is what you’d study since you are hitting the tennis ball. Or a football player running and using cleats you would study all of that since the cleats help the athlete run and cut.
What is the anatomic reference position?
body posture where a person stands upright, facing forward, with arms at their sides, palms facing forward, feet flat and together, and toes pointing straight ahead
What are quantitative spatial reference systems?
Where you describe the movement of an athlete using numbers and measuring those movements
What are qualitative spatial reference systems?
Things that describe the technique or skill performed. Describes the performance outcome. Example: describing that the gymnast stuck the landing, The gymnast ran in the south direction and did 3 flips
What sorts of careers might a person have who was trained in biomechanics?
developing different equipment for nike, speedo, or other companies like that. Doing research as well.
What is cartesian coordinate system?
use of a coordination system to map the motion and body position of the athlete (3.4). (uses an X,Y graph)
