How much do you think your pulse will increase during the two activities?

To determine how much your pulse might increase during two different activities, you need to consider several factors including the intensity of the activities, your current fitness level, your age, and your resting heart rate.

Assuming the activities vary in intensity, like walking (low intensity) versus running (high intensity), one would expect the pulse to increase more during the activity with greater intensity, i.e., from walking to running.

For example, if your resting heart rate is around 70 beats per minute (bpm), a moderate-intensity activity like brisk walking might bring your pulse up to about 100-120 bpm, whereas a vigorous activity like running might increase your pulse significantly more, potentially anywhere from 120 to 160+ bpm, depending on the pace and your fitness level.

To better estimate your pulse increase, you can use the Karvonen formula which is: Target Heart Rate = ((max heart rate - resting heart rate) × desired intensity) + resting heart rate.

Where:

- Max heart rate is roughly calculated by 220 minus your age. - Resting heart rate is the number of heartbeats per minute when you are at rest. - Desired intensity is the percentage of heart rate elevation during activity, often expressed as a fraction (for example, 0.50 for 50% intensity or 0.70 for 70% intensity).

However, the actual increase in your pulse can only be determined accurately by measuring it before and during the activities.
