what does a shuttle run do?

Question

test used to measure flexibility

the elasticity of muscle groups

the ability of muscles to preform work over time

the body's ability to do several different tasks at one time

the ability of the heart and lungs to be active over a long period of time

the capacity of muscles to generate amounts of force in a short period

test approved by the president of the United states

measures coordination

measures muscular endurance

measures muscular strength

Answer 1

The shuttle run is primarily used to measure agility and speed, as it involves running back and forth between two markers placed a set distance apart. While it can indirectly reflect aspects of muscular endurance and cardiovascular fitness due to the repeated sprints, it is not specifically designed to assess flexibility, the elasticity of muscle groups, or the ability of the heart and lungs to be active over a long period of time.

From the options you provided, the shuttle run most closely aligns with measuring coordination and could also relate to assessing muscular endurance due to the repeated bursts of effort required. However, its primary focus is on agility and quickness in changing direction.
