General Biomechanics 1
Aside from the surface, what is one other factor that can impact the way we absorb force through the body?
What is - E.g. Technique and equipment
Which of the following surfaces would provide the highest ground reaction force on the body? Grass, road, sand
What is - Road
Outline one role of biomechanics
What is - To improve athlete performance
In the human body, angular motion can take place around how many different axis of rotation?
What is - 3
This person's laws are used for biomechanics
Who is Newton?
Outline one simple way a basketball player could reduce their chance of injury when rebounding a basketball with relation to force absorption
What is - E.g. Bend their knees, wear basketball shoes with cushioning
What is - Action of muscles and tendons that act together to produce forces that cause movement
Outline one other role of biomechanics
What is - To prevent injury
Which axis of rotation runs from the navel to lower back?
What is - Medial axis
When an object moves in a straight line
What is linear motion?
Outline how biomechanical analysis could help reduce injuries?
What is - reduction of wear and tear on joints and ligaments, analysis used to help eliminate muscle imbalances
List 2 examples of an external force with relation to biomechanics
What is - Gravity, air resistance, water resistance, friction
List the three phases of movement
What is preparation, action, follow through
Which axis of rotation runs from head to toe vertically?
What is - Longitudinal / Sagittal axis
A combination of two types of motion forms this type of motion
What is - General motion
Explain one point regarding how can an athlete’s performance be improved through using biomechanical analysis?
What is - E.g. Selecting appropriate equipment for the athlete, improving power, improving speed, improving energy conservation (efficiency)
Describe external force with relation to biomechanics
What is - The interaction between the body and the environment. These can include contact forces and non-contact forces.
List three pieces of sporting equipment that can absorb force
What is - Glove, helmet, pads etc
Which axis of rotation runs from hip to hip?
What is - Horizontal axis
When movement of an object happens around an axis
What is angular motion?
Explain how a piece of sporting equipment has been improved over time with reference to biomechanical principles
What is - E.g. Boots increasing friction which provides better grip and traction, which helps players maintain stability and balance while running, changing direction, and stopping quickly.
Describe internal force with relation to biomechanics
What is - Structures of the body that interact to produce movement
Define or explain biomechanics
What is - The study of motion and the effects of forces relative to the body
Provide a sporting movement example for each of the different types of axis of rotation
What is - E.g. Medial axis – gymnast performing cartwheel, longitudinal / Sagittal axis – ice skater spinning, horizontal axis – diver performing forward somersault
_____ = mass x acceleration
What is Force?
