- In this lab exercise blood pressure at rest was to be compared against two different variable: 1) 2 minutes of exercise and 2) exposure to cold temperature. Explain the results shown below in terms of the physical effects these variables are having on the body: Blood Pressure at Rest/Room Temp Blood Pressure after 2 Minutes Exercise Blood Pressure after Cold Exposure 120/80 110/75 130/85Briefly describe the cardiovascular response to an increasing intensity exercise test. Be sure to mention the physiological basis for WHY these responses occur. Do this by discussing the changes in HR, SV, SBP, and DBP.Table 1 Blood pressure recordings for all positions Body positions Mean systolic BP Mean diastolic BP Sitting position Standing position Supine position Supine position with crossed legs 102-8 + 11-4 65-7 + 82 99.9 + 10-2 66-0 + 8-7 107-9 + 10-7 66-9 + 96 107-0 + 86 66-7 + 7-3 F= 444, P 00s BP, blood pressure. Table 2 Pairwise comparisons between positions in systolic BP Sitting position position Standing Supine position Standing position Supine position Supine position with crossed legs *, the mean difference is significant at the level 0-05 level. Adjustment for multiple comparisons: Bonferroni. Does age factor has any influences in the blood pressure with the change of body positions?
- The primary factor that dictates the magnitude of blood pressure increase (how high the blood pressure goes) during acute resistance exercise to maximum is the amount of muscle mass being recruited (e.g., a 10-repetition squat vs. a 10-repetition calf raise to failure). True FalseThe below graph shows changes in several cardiovascular parameters as the result of increased intensity of exercise in a population of untrained individuals. What commonly measured cardiovascular parameters might the curves labeled A, B, and C represent? What are the corresponding units for the y-axis of each measure? For your reference, the two labeled curves represent the Pulmonary Capillary Wedge Pressure (PCWP) and the Central Venous Pressure (CVP), both of which are measured in mmHg.Make a list of the different physiological equations: 1.
