Explanation:

High - intensity aerobic exercises elevate the heart rate significantly. Running is a high - intensity activity compared to walking (low - intensity), Tai Chi (low - moderate intensity), and stretching (non - aerobic). The VO2 Max Test measures the maximum amount of oxygen an individual can utilize during intense exercise and is a gold standard for cardiovascular fitness assessment, while flexibility tests measure joint range of motion, the beep test is a sub - maximal aerobic test, and the step test is also a sub - maximal assessment.

Answer:

1. B. Running
2. A. VO2 Max Test
