Center of Gravity and Stability Concepts

The video tutorial explains how balance is maintained through the relationship between the center of gravity (COG) and the base of support (BOS). It defines COG as the point where the body's mass is concentrated and BOS as the area in contact with the ground. The tutorial discusses how balance is affected when the COG moves outside the BOS, leading to instability. It also compares low and high centers of gravity, using examples like sumo wrestlers and tiptoe balancing to illustrate how these affect stability.

What two concepts are crucial for maintaining balance?

• Flexibility and strength

• Height and weight

• Speed and agility

• Center of gravity and base of support

Where is the center of gravity typically located in the human body when standing upright?

• In the feet

• In the arms

• In front of the lumbar vertebrae

• In the head

What happens when you bend forward or backward in terms of center of gravity?

• The center of gravity becomes fixed

• The center of gravity remains unchanged

• The center of gravity disappears

• The center of gravity moves accordingly

How does the base of support affect stability?

• The base of support has no effect on stability

• A larger base of support increases stability

• Stability is only affected by the center of gravity

• A smaller base of support increases stability

What is the effect of a narrow stance on the base of support?

• It makes the base of support unstable

• It has no effect on the base of support

• It decreases the base of support

• It increases the base of support

What happens when the center of gravity moves outside the base of support?

• The center of gravity becomes fixed

• The base of support increases automatically

• The body loses balance

• The body becomes more stable

What is the relationship between the center of gravity and the base of support for maintaining balance?

• They are unrelated

• The center of gravity must be within the base of support

• The center of gravity must be outside the base of support

• The base of support must be above the center of gravity

What is a common strategy used by sumo wrestlers to maintain stability?

• Lowering their center of gravity

• Jumping frequently

• Standing on one leg

• Keeping their feet close together

How does a high center of gravity affect stability?

• It has no effect on stability

• It increases stability

• It decreases stability

• It makes the body immovable

Why is balancing on tiptoes more challenging?

• The center of gravity is lower

• The center of gravity is higher

• The base of support is larger

• The base of support is more stable
