RAST stands for which term?

• A. Repeated Anaerobic Sprint Test
• B. Repeated Aerobic Strength Test
• C. Rapid Anaerobic Speed Test
• D. Regular Aerobic Sprint Test

Answer: (A)

RAST is a test that measures how well someone can sustain high-intensity sprinting across several efforts with short rest periods. It targets anaerobic capacity and fatigability, using repeated sprints to see how performance changes from the best to the worst effort and across the series.

The term Repeated Anaerobic Sprint Test fits because the protocol revolves around multiple short, maximal sprints powered mainly by anaerobic energy systems (ATP-PC and glycolysis) rather than aerobic endurance. Outputs commonly include the total time, the best single sprint, and a fatigue index that describes how much performance declines over the repetitions. This setup is distinct from tests focusing on aerobic strength or longer, lower-intensity efforts, which is why the other options don’t align with what RAST measures.
