1. Results Section: The Impact of Exercise on Cardiovascular Health
In this study, the impact of exercise on cardiovascular health was investigated. The aim of the research was to determine whether regular exercise has a positive effect on cardiovascular health indicators such as blood pressure, heart rate, and cholesterol levels. A sample of 100 participants, aged between 30 and 50 years, was recruited for the study. They were randomly assigned to either the exercise group or the control group. The exercise group was required to engage in moderate-intensity aerobic exercise for 30 minutes, five days a week, for a period of 12 weeks. The control group was instructed to maintain their usual sedentary lifestyle without any changes.
To assess cardiovascular health, several measurements were taken at baseline and after the 12-week intervention period. Blood pressure was measured using a digital sphygmomanometer, heart rate was recorded with a heart rate monitor, and cholesterol levels were determined through a blood test. The data collected were analyzed using descriptive statistics and inferential statistics.

Note: Values represent mean (standard deviation) for each group.
The results presented in Table 1 show a clear difference in cardiovascular health indicators between the exercise group and the control group. Baseline blood pressure, heart rate, and cholesterol levels were similar between the two groups, indicating that they were comparable at the beginning of the study. However, after the 12-week intervention period, significant improvements were observed in the exercise group compared to the control group.
Regarding blood pressure, the exercise group showed a decrease of 10 mmHg in systolic blood pressure and 5 mmHg in diastolic blood pressure. In contrast, the control group exhibited little change in blood pressure readings. This reduction in blood pressure is clinically significant, as it falls within the hypertensive range. It suggests that regular exercise can effectively reduce blood pressure and contribute to overall cardiovascular health.
Moreover, heart rate in the exercise group decreased by an average of 7 beats per minute, while the control group showed minimal change. This reduction in heart rate suggests improved cardiovascular fitness in the exercise group. A lower resting heart rate indicates that the heart is working more efficiently, which can help prevent cardiovascular diseases and improve overall health.
In terms of cholesterol levels, the exercise group experienced a decrease of 20 mg/dL on average, while the control group showed an increase of 5 mg/dL. This reduction in cholesterol levels is significant, as high cholesterol is a major risk factor for cardiovascular disease. Regular exercise has been shown to lower LDL (bad) cholesterol and increase HDL (good) cholesterol, contributing to improved cardiovascular health.
In conclusion, the results of this study provide strong evidence that regular exercise has a positive impact on cardiovascular health. The exercise group showed significant improvements in blood pressure, heart rate, and cholesterol levels compared to the control group. These findings highlight the importance of incorporating exercise into daily routines to maintain cardiovascular health and prevent the development of cardiovascular diseases.

3. Feedback:
Response to Classmate 1:
Your results section is well-organized and clearly presents the findings of your study. The table you included provides a comprehensive overview of the cardiovascular health indicators for both the exercise group and the control group. Additionally, the narrative paragraph effectively summarizes the key findings and their implications. One possible suggestion for improvement would be to include p-values or confidence intervals in the table to indicate the statistical significance of the observed differences. This would enhance the interpretation of the results and provide a clearer understanding of the magnitude of the effects.
Response to Classmate 2:
I appreciate the clarity and coherence of your results section. The presented table concisely summarizes the key findings of your study and allows for easy comparison between the exercise and control groups. The narrative paragraph provides a succinct interpretation of the data and emphasizes the significance of the observed changes in cardiovascular health indicators. One potential suggestion for improvement would be to include additional measurements, such as body mass index or waist circumference, to provide a more comprehensive assessment of cardiovascular health. This would enhance the validity and applicability of the study’s results.
