The Progressive Aerobic Cardiovascular Endurance Run (PACER) is a
multistage shuttle run created by Leger and Lambert in 1982.The PACER is
designed to measure aerobic capacity, which is characterized by endurance,
performance, and fitness. The objective of the PACER is to run as long as possible
while keeping a specified pace. Students run back and forth across a 20-meter
space at a pace that gets faster each minute. A point is scored for each 20-meter
distance covered. The test is easier in the beginning but progressively gets more
difficult. In comparison to distance running, the PACER is a more effective, fun,
and easy way to measure aerobic capacity that encourages participation from all
youth and is relatively easy to score and administer.
