The 6-minute walk test is correlated with which aspect of fitness in older adults?

The 6-minute walk test is primarily used to assess cardiorespiratory endurance in older adults. This test evaluates how far an individual can walk in six minutes, providing a measure of aerobic capacity and general fitness levels. Cardiorespiratory endurance reflects the efficiency with which the body can deliver oxygen to muscles during physical activity, which is particularly important as individuals age.

Participants' performance in the 6-minute walk test correlates highly with their ability to undertake daily activities, reflecting their overall health and fitness level. A longer walking distance in this test usually indicates better cardiovascular health and endurance, which are crucial for maintaining independence and quality of life in older adults.

While factors like muscle strength, flexibility, and balance can influence overall mobility and performance, the specific focus of the 6-minute walk test is on aerobic capacity and endurance. Therefore, the correct choice aligns perfectly with the primary goal of the test.
