Question

____ is cardio that’s done at an intensity that you can maintain for only a short time.

A. Varied-state training
B. Steady-state training
C. Low-intensity interval training
D. High-intensity interval training (HIIT)

Answer 1

High-intensity interval training (HIIT) is the correct answer, involving short intense bursts of activity followed by rest periods.

Step-by-step explanation:

The correct answer is D. High-intensity interval training (HIIT). HIIT is a form of cardiovascular exercise that alternates between short periods of intense anaerobic exercise with less intense recovery periods. Unlike steady-state cardiovascular workouts that are performed at a consistent speed and intensity, HIIT workouts involve bursts of vigorous activity that you can sustain only for a short duration before needing a rest to recover.

Aerobic exercise refers to the type of exercise that is moderate in intensity and can be sustained for a longer period since it is supported by aerobic metabolism. In contrast, anaerobic exercise includes activities like sprinting, which are too intense to sustain for long periods and therefore done in shorter bursts, as seen in HIIT workouts.

Answer 2

Answer: Aerobic exercise is cardio done at an intensity that you can maintain for only a short time.

Explanation: What is Aerobic exercise?

Aerobic exercise is any type of physical activity that requires a significant amount of oxygen to be delivered to the muscles in order to sustain the activity. It is also commonly referred to as cardio exercise or cardiovascular exercise, as it primarily focuses on improving the health and efficiency of the heart and lungs.

Examples of aerobic exercise include running, cycling, swimming, dancing, and brisk walking. These activities typically involve large muscle groups, such as the legs, and are performed for an extended period of time at a moderate intensity, which allows for the body to continuously deliver oxygen to the muscles.
