The 8 foot up and go test measures which of the following?

The 8 Foot Up and Go test is designed specifically to assess agility and dynamic balance in older adults. During this test, the participant begins seated in a chair, stands up, walks as quickly as possible to a designated cone or marker 8 feet away, circles the cone, and returns to sit back down in the chair. This activity requires the individual to perform a series of movements that engage different muscle groups and require coordination, timing, and balance.

Agility involves the ability to move quickly and change direction efficiently, while dynamic balance refers to maintaining stability while in motion. The test emphasizes how well a person can navigate these movements safely and effectively, which is particularly important for older adults to help prevent falls and maintain independence. Thus, the correct answer highlights the primary purpose of the test.
