Answer:
Introduction:
The purpose of this lab experiment is to measure the change in heart rate during exercise. Heart rate is an important indicator of cardiovascular health and fitness, and understanding how it changes during physical activity can help individuals make informed decisions about their exercise routine. In this experiment, we will be measuring heart rate at rest and during exercise, and comparing the results to assess the impact of physical activity on heart rate.
Methods:
To measure heart rate during exercise, we used a heart rate monitor and performed a moderate-intensity exercise on a stationary bike for 20 minutes. We started by measuring the heart rate at rest for one minute, and then began the exercise. During the exercise, we recorded heart rate every five minutes. We repeated the process three times to ensure accuracy and consistency of results.
Results:
Our results show that heart rate increased significantly during exercise. The initial resting heart rate was 70 beats per minute, and it increased to an average of 125 beats per minute during the exercise period. The heart rate remained elevated for several minutes after the exercise ended before returning to resting levels.
We represented our data using a chart and a graph. The chart shows the heart rate at rest and during exercise for each trial, while the graph shows the average heart rate across all three trials.
Discussion:
The increase in heart rate during exercise is a normal physiological response to physical activity. During exercise, the body requires more oxygen and nutrients, and the heart responds by pumping more blood to meet these demands. The increase in heart rate is also an indication of the intensity of the exercise, with higher intensity exercise resulting in a greater increase in heart rate.
Our results suggest that moderate-intensity exercise on a stationary bike can significantly increase heart rate, and therefore be an effective way to improve cardiovascular health and fitness. However, it is important to note that heart rate response to exercise can vary depending on factors such as age, fitness level, and underlying health conditions. Individuals should consult with a healthcare professional before starting an exercise routine to ensure safety and effectiveness.
Conclusion:
In conclusion, this lab experiment demonstrates the impact of exercise on heart rate. Our results show that heart rate increases significantly during moderate-intensity exercise on a stationary bike, indicating the effectiveness of this type of exercise for improving cardiovascular health and fitness. These findings can help individuals make informed decisions about their exercise routine and promote a healthier lifestyle.
