through HR, BP, and pulse oximetry measurements. The subjects results were indicative of normal cardiac function. At rest, the subject had HR and BP measurements within the average range for both sex and age (HR 62 bpm, BP 120/70 mmHg). Also at rest, the pulse oximetry reading indicated normal oxygen saturation of hemoglobin (95% saturation). As seen in table 1.1 in the results, the subjects HR increased simultaneously with an increase in exercise intensity. BP increased along with exercise intensity and duration. In addition, pulse oximetry slightly rose with exercise, but stayed within the normal range (98% saturation). In terms of recovery, it took approximately six minutes post- exercise for the subject’s HR and BP to return relatively to his normal resting cardiac state (HR 66 bpm, BP 120/70 mmHg). Overall, the subject showed signs of having a healthy, well functioning, cardiovascular system. However, there were some variable factors present that may have influenced the results of the assessment. In terms of HR, it is influenced by body position, diet, consumption of drug, alcohol, and/or caffeine, and any level of fatigue. Also, the lowering of stroke volume from dehydration is related to an increase in HR (Gonzalez 2000). The assessors used a HR monitor to get a more exact measurement of the subject’s HR. BP readings can be affected by; the previously stated affecters of HR (caffeine intake, etc.), a lack of experience or ignorance of the assessor, and/or inaccurate equipment. In this assessment, the modified protocol prohibited the evaluators from measuring BP and pulse oximetry consistently throughout the exercise time. A bike or treadmill would be much easier for the assessors to measure BP at consistent intervals. This study was important in learning the affects of exercise on HR, BP, and pulse oximetry, and would have been more accurate and useful if the evaluators had access to a wider range o...
