LABORATORY REPORT Activity: Name: Instructor: Date: Effect of Exercise on Arterial Pressure and Vascular Resistance Takila Martin Timothy Pearson 02.16.2015 Predictions Exercise will cause MAP to increase Exercise will cause systemic vascular resistance to increase Exercise will cause CO to increase Materials and Methods 1. Dependent Variable HR, SV, BP 2. Independent Variable level of activity 3. Controlled Variables gender, age 4. Identify one variable that was not controlled in this study (not dependent or independent variables; hint: think about possible differences between subjects).
What was the average exercising systolic BP? 147 mmHg c. The range of normal resting systolic BP for the subjects in this experiment is 115-125 mmHg. Did systolic BP increase, decrease, or not change with exercise? increased 2. Resting and exercising diastolic BP - a.
Blood glucose levels then slowly declined for each successive measurement. Levels decreased an additional 25.1 mg/dl to 118.9 mg/dl at the 60 minutes measurement, 3.3 mg/dl to 115.6 mg/dl at 90 minutes, and 14.6 mg/dl to 101.0 mg/dl at 120 minutes. At the two-hour measurement, the blood glucose level was 12.3 mg/dl over the baseline measurement of 88.7 mg/dl. For the control group, consuming 296 ml of water did not greatly affect blood glucose levels. The trend was a slight decline from the baseline measurement of 99.0 mg/dl to the two-hour measurement of 89.4 mg/dl.
If the value of x is postnatal age of 30 hours, what is the value for Yˆ or SBP for neonates ≤1,000 grams? Show your calculations. 208 EXERCISE 27 • Simple Linear Regression 6. In the legend beneath Figure 2, the authors give an equation indicating that systolic blood pressure is SBP = 50.3 + 0.12x. If the value of x is postnatal age of 30 hours, what is the value for Yˆ or SBP for neonates 1,001–1,500 grams?
Repolarization is the recharging of the heart after each heartbeat (VanPutte, 2011). There are five main components of an electrocardiogram: P, Q, R, S and T. The p waves, corresponds to depolarization of the atria (VanPutte, 2011). The QRS complex represents the progressive wave of ventricular depolarization (VanPutte, 2011). The T wave represents the repolarization of the ventricles. In this lab experiment four leads were used: one each on the left and right wrist and one each placed above the ankle of the left and right foot.

Systolic blood pressure increases, while the diastolic blood pressure maintains the same or slightly decreases as the intensity of exercise and activity increases. The larger number usually characterizes the systolic blood pressure which precedes the diastolic.
Due Friday 3/30 at 8:oo pm; Late Assignments not accepted Open the attachment entitled “Life Expectancy Worksheet”. Follow the instructions to complete the worksheet, then answer the following questions: 1) By how many years did your predicted longevity change as a result of the factors listed below? For each factor, a negative change indicates a decrease in longevity and a positive change in years indicates an increase in predicted longevity. a. Genetic history.
