Final answer:

The investigation's accuracy can be improved by ensuring consistency in measuring pulse rates and increasing the sample size. The pulse rate reflects cardiovascular fitness levels. The heart rate increases during exercise to meet the elevated oxygen demand in muscles.

Explanation:

One way to improve the accuracy of this investigation is to ensure consistency in measuring the pulse rate by using the same method for all participants. Another way is to increase the sample size to get more representative data.

Conclusion: The pulse rate indicates cardiovascular fitness levels, with a lower heart rate at rest and a quicker return to resting pulse rate post-exercise suggesting better fitness.

Explanation of heart rate increase during exercise: During exercise, the heart rate increases to pump more oxygenated blood to muscles, fulfilling the increased demand for energy production.
