3.11-Balance and Stability in Biomechanics

What is balance primarily concerned with in biomechanics?

• The ability to enhance flexibility

• The ability to increase speed

• The ability to resist external forces

• The ability to remain upright and control equilibrium

Which type of balance is demonstrated when a gymnast holds a needle scale position on a balance beam?

• Rotational balance

• Static balance

• Transitional balance

• Dynamic balance

What does stability refer to in biomechanics?

• The speed of movement

• The degree of motion

• The degree to which a person can resist challenges to their state of equilibrium

• The flexibility of joints

What factor increases the stability of a person or object?

• Decreased mass

• Larger base of support

• Higher center of gravity

• Smaller base of support

What is the base of support?

• The weight distribution in motion

• The area beneath a person or thing that is in contact with a supporting surface

• The alignment of the spine

• The top area of an object touching another object

How can athletes modify their base of support?

• By modifying their equipment

• By adjusting their stance or position

• By altering their clothing

• By changing their dietary habits

What is the line of gravity?

• The path of an object in motion

• The alignment of the eyesight

• The direction in which gravity is acting on a person or thing

• The force exerted by muscles

Where is the centre of gravity located in a perfectly round object like a tennis ball?

• At the base of the object

• At the top of the object

• In the exact centre of the object

• Outside the object

What is the effect of a larger base of support?

• Greater stability

• Reduced control

• Increased speed

• Decreased stability

What does dynamic balance involve?

• Enhancing muscular strength

• Maintaining balance while moving

• Resisting changes in speed

• Maintaining balance while stationary
