What term is described by heart rate ranges of 65-75% HRmax, 76-85% HRmax, and 86-90% HRmax?

What term is described by heart rate ranges of 65-75% HRmax, 76-85% HRmax, and 86-90% HRmax?

• A. Cardio training zones
• B. Interval training
• C. Stabilization
• D. Acute variables

Answer: (A)

These ranges describe different levels of cardio effort, grouped into cardio training zones. The 65-75% HRmax zone is a light-to-moderate effort, good for building a base and endurance. The 76-85% HRmax zone is more vigorous and improves aerobic capacity, while the 86-90% HRmax zone is a high-intensity segment used for short, intense bouts to boost performance. Together, they define the cardio training zones that guide how hard a workout should be. Other options don’t fit because interval training describes work/rest structure, stabilization focuses on technique at lower intensity, and acute variables are the workout parameters (duration, reps, rest, etc.) rather than the labeling of intensity levels.
