Blood Pressure Data Analysis

Results
Over a five-day period at varying times of day, 342 college-aged men and women recorded their heart rate and blood pressure under different conditions. In Figure 1, the blood pressure data of an individual female in very good condition is shown under the effect of posture. Figure 2 shows the blood pressure data of the same well-trained female under the effect of exercise. The individual data in both figures 1 and 2 fell outside the standard error of the mean for the class. Figure 3 shows the class data (N=335±3) for blood pressure under the condition of exercise. The effects of gender, weight, age, time of day and condition were statistically removed to avoid having confounding variables. There were statistically significant differences
Figure 4 shows the class data (N=335±3) for heart rate under the effect of exercise. This data set also had any confounding variables removed. Heart rate at rest was statistically significantly different from all of the other conditions and HR after moderate exercise was different than HR at rest, after heavy exercise and after 8 min of recovery. HR after heavy exercise was significantly different from all of the other data points and HR after 2, 3, 4, and 6 min of recovery was different from HR at rest and HR after heavy exercise. In Figure 5, the effect of conditioning on blood pressure during exercise is shown. For each experimental condition, there are three different levels of conditioning (poor, good, and very good). The effects of age, gender, weight and time of day were statistically removed to avoid confounding variables. In Figure 6, the effect of conditioning on heart rate is shown. Again, confounding variables were removed. There was a significant relationship between the level of conditioning and heart rate across all experimental
The individual results of the well-trained female showed varying results in blood pressure. Considering this is a well-trained female college student, exercise or caffeine prior to the lab could explain the above average blood pressure. In the posture portion of the experiment, a drop in blood pressure was expected when the individual rapidly stood up after lying prone however, the BP remained stable. If this measurement was not taken quickly enough or the individual did not stand up fast enough, the baroreceptors would have already adjusted for the decrease in arterial pressure in the upper body thereby stabilizing blood pressure. In the class data for the effect of conditioning on heart rate, it was found that individuals with a higher level of conditioning had a lower heart rate at all exercise levels. Their resting heart rate decreased by 6.7 beats per minute from poor to good fitness and again from good fitness to excellent fitness. Highly trained individuals also remained at a lower heart rate during exercise. Individuals in poor or good condition demonstrated a much higher resting heart rate and reached a higher heart rate during the moderate and heavy exercise. Participants in this experiment that exercised regularly would have a lower heart for many reasons. Athletes tend to have a larger blood volume and, therefore, a greater carrying capacity of oxygen.
