Answer:
Step-by-step explanation:
The maximum training heart rate is determined using the following formula:
220 - age = Maximum Heart Rate (MHR)
In this case, the person's age is 55, so we can calculate the MHR as:
220 - 55 = 165 beats per minute
Next, we subtract the resting heart rate (RHR) from the MHR to calculate the heart rate reserve (HRR):
165 - 75 = 90 beats per minute
To determine the maximum intensity of the workout, we multiply the HRR by 0.85 and add the resting heart rate:
0.85 * 90 + 75 = 141 beats per minute
Therefore, the maximum heart rate during training for Dan is 141 beats per minute.
Dan's heart rate training zone can be determined based on his maximum heart rate:
The lower end of the training zone is calculated as 70% of the maximum heart rate:
0.70 * 141 = 98.7 beats per minute (rounded to 128 beats per minute)
The upper end of the training zone is calculated as 85% of the maximum heart rate:
0.85 * 141 = 119.85 beats per minute (rounded to 141 beats per minute)
Therefore, Dan's heart rate training zone is between 128 and 141 beats per minute.
Interval training can help improve cardio performance. It involves alternating between high-intensity bursts of exercise and periods of rest or lower intensity. By incorporating interval training into his routine, Dan can see improvements in his cardio performance.
It is also important for Dan to reassess his baselines routinely. This means periodically checking his heart rate, monitoring his progress, and adjusting his training plan accordingly. Regular reassessment will help Dan track his improvements and make any necessary modifications to his workout routine.
Remember, it's always a good idea to consult with a healthcare professional or a certified fitness trainer before starting any new exercise program or making significant changes to your training routine. They can provide personalized advice and guidance based on your individual needs and goals.
