What does a VO2 Max score tell us about a person's "engine" and overall health?

VO2 Max, Lactate Threshold, Maximal Oxygen Uptake, Critical Power.

2.12.8 Designs and implements a plan that applies knowledge of aerobic, strength and endurance, and flexibility training exercises.

DOK 3: Interpret your test results compared to national norms for your age group. What factors (genetics vs. training) influenced this?

DOK 4: Formulate a 4-week "intervention plan" to increase your distance in the 12-minute test by 5%.

In the adult world, "cardio" is often a primary tool for disease prevention and mental health maintenance. However, many people quit because they lack a plan or overtrain. This unit teaches students how to interpret their body’s data—like heart rate recovery and aerobic thresholds—to train smarter, not just harder. Whether preparing for a 5K or simply managing career stress, these skills allow students to curate their own fitness journey without needing a personal trainer.
