Hello. This question is incomplete. The full question is:
If Sally has a fitness goal to improve her mile run time from 10 minutes and 15 seconds per mile to below 8 minutes and 30 seconds per mile in 3 months, which training plan using the heart rate zones would best help her achieve her goal?
Sally should do all her workouts in zone 4 in order to increase her anaerobic threshold.
Sally should most of her workouts in the 5th zone to increase speed.
Sally should do most of her workouts in the 1st and 2nd zones to increase her ability to withstand fitness activity.
Sally should do most of her workouts in zone 3, but have some of her workouts
Answer:
Sally should do all her workouts in zone 4 in order to increase her anaerobic threshold.
Explanation:
The heart rate zones are used to measure the athlete's cardiovascular strength and to improve the intensity of physical training. These zones are divided into 5 phases, with phases 1, 2 and 3 geared to provoke the athlete's adaptation to training intensity and 4 and 5 geared to cause greater physical performance to workouts of greater intensity.
Sally wants to increase the intensity of her training, for this reason, we can conclude that she must do all her exercises in zone 4. This is because this zone has the ability to increase the body's aerobic threshold, promoting increased resistance and speed of the body , which will allow Sally to finish her training in less time.
