Carotenoid Consumption Lab 1 -

Discussion Questions -

1. Do you eat five-seven servings of fruits and vegetables a day? Per week? Do you eat a plant-based diet? Please explain.

2. How do carotenoids promote good health and protect the body from cancer risk?

3. How do carotenoids fight inflammation and protect the immune system?

4. Not all carotenoids perform the same tasks. Please explain the different functions of pro-vitamin A carotenoids and non pro-vitamin A carotenoids and their food sources.

5. How do the anti-oxidant properties of carotenoids fight free radicals damage and protect the cardiovascular system?

Submaximal Exercise Testing Lab 2 -

Background and Purpose - The purpose of this assessment is it provide the pretesting, testing, and post testing procedures for conducting a submaximal graded exercise test on the cycle ergometer to develop skill in administering this type of test (Roberts, 2019). Submaximal testing can provide estimates of maximal aerobic capacity by considering test duration at a given workload by using the provided VO2 max formula and graph (Figure 3). Submaximal exercise testing estimates maximal aerobic capacity through the determination of the one or more submaximal work rates. Lastly, the use of the submaximal blood pressure(BP), workload, heart rate(HR), relative perceived exertion(RPE), and other subjective indices can provide valuable information regarding one's functional response to exercise (Roberts, 2019).

Questions -

1. Describe the HR response during exercise and recovery. Were these responses normal?

2. Describe the systolic and diastolic BP responses during exercise and recovery. Were these responses normal? The systolic blood pressure rapidly increased as the stages progressed and the diastolic remained constant (Figure 4). Although the exact measurement was not recorded, it was noted that the systolic blood pressure gradually decreased during recovery. The blood pressure responses to exercise and recovery were normal.

3. What was the client's highest exercise HR? How did it compare to the client's age-predicted HRmax? What was the client's highest RPE value? The client's highest exercise HR was 124 bpm, which was 75 bpm lower than the client's age-predicted HRmax. The client's highest RPE was 13, which was relatively concurrent with the client's highest exercise HR.

4. How well did the palpated exercise HR data compare to the HR monitor or ECG HR data?

5. How close were the client's estimated VO2max values calculated from the multistage equation and graphing method? The client's VO2 max levels were relatively close with a difference of 0.53 L/min. Margins of error in these values most likely came from the estimations that had to be taken while graphing the line of best fit of the workloads and the age-predicted maximum HR(Figure 5).

6. Interpret the client's VO2max test results. Does this client need to improve his or her cardiorespiratory fitness level? The client had a high cardiorespiratory fitness level and does not need to improve upon their current condition in order to achieve having good cardiorespiratory fitness.

7. What difficulties did you encounter in measuring HR and BP during the max GXT? How can you minimize these problems?

8. Describe the reasons that would prompt you to stop the GXT before the client voluntarily terminates the test. General indicators for stopping the GXT before the client voluntarily terminates the test are a drop in systolic BP of greater than 10 mmHg from the baseline despite the workload, excessive rise in BP, shortness of breath, leg cramps, wheezing, signs of poor perfusion, failure of HR to increase with increased exercise intensity, and failure of test equipment(Gappmaier, 2012).
