Question

What type of training typically elicits >80-100% peak HR (i.e., 4 min at 85-95% peak HR, then 3 min rest at 70% peak HR)?

a) Endurance training
b) High-Intensity Interval Training (HIIT)
c) Strength training
d) Flexibility training

Answer 1

The training protocol that includes intervals at 85-95% peak heart rate followed by rest at 70% is known as High-Intensity Interval Training (HIIT), which relies on anaerobic exercise to increase heart rate and improve fitness.

Step-by-step explanation:

The type of training that typically elicits >80-100% peak heart rate (HR), including intervals such as 4 minutes at 85-95% peak HR followed by 3 minutes rest at 70% peak HR, is High-Intensity Interval Training (HIIT). HIIT involves short bursts of intense physical activity—anaerobic exercise—such as sprinting, followed by periods of rest or low-intensity exercise. This contrasts with endurance, strength, and flexibility training, which have different effects on heart rate and different goals regarding muscular and cardiovascular improvements.

Aerobic exercise involves sustained physical activity at a low to moderate level over a long period, primarily using slow-twitch muscle fibers and improving cardiovascular endurance. Examples include cycling and brisk walking. In contrast, anaerobic exercise utilizes fast-twitch muscle fibers over short periods, leading to higher heart rates and increased basal metabolic rate (BMR). HIIT combines these short, intense anaerobic exercises with rest or low-intensity periods to create a varied, high-intensity workout.
