Introduction: In this experiment, cardiovascular fitness is being determined by measuring how long it takes for the test subjects' to return to their resting heart rate. Cardiovascular fitness is the ability to "transport and use oxygen while exercising" (Dale 2015). Cardiovascular fitness utilizes the "heart, lungs, muscles, and blood working together" while exercising (Dale 2015). It is also how well your body can last during moderate to high intensity cardio for long periods of time (Waehner 2016). The hypothesis is that people who exercise for three or more days will return to their resting heart rate much faster than people who only exercise for less than three days.

The beep test is the subject received a score 13.5, this meant that the subject covered a distance of 2460 metres and ran for a period of 13 minutes and 2 seconds. Their starting heart rate was 110 and they reached a maximum of 197. Lastly their final rate of perceived exertion (RPE) was 9 meaning they found themselves working ‘really, really hard’ and at maximum intensity at the completion of the test.

the 2020 target is set at 49.1 percent. This objective reports that many people have taken the recommendations from their health educator or health specialist to increase their physical activity to reduce and maintain a healthy life. In this objective the target setting method is set at 10 percent improvement, not all objectives reach their target setting. When target settings are set and are not met

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?

The anaerobic threshold (AT), also called the “lactate threshold,” is the exertion level between aerobic and anaerobic training. The AT is the point during exercise where your body must switch from anaerobic to aerobic metabolism. Anaerobic exercise consists of weightlifting, sprinting, and jumping. Once an athlete reaches its anaerobic threshold, lactic acid builds up in the muscles faster than it can be cleared away resulting in muscle cramps. The AT is a useful measure for deciding exercise intensity for training and racing in endurance sports. On average untrained individuals have a low AT (approximately 55 % of VolumeO2max), and elite endurance athletes have a high AT (approx. 80 - 90% of VolumeO2max). lactate threshold.(1) Studies have been conducted on finding methods of improving anaerobic threshold. Lately High-intensity interval training (HIIT) has become a popular training modality in competitive athletes, recreationally-trained individuals, and clinical populations. HIIT consists of repeated bouts of short to moderate duration exercise

| Which of the following resting pulse and resting blood pressure results would be typical of a well-conditioned athlete? 72 and 150/90; 48 and 110/80; 66 and 120/95; 84 and 110/75.

The controlled variable included the exercise bike and heart rate monitor. There are several limitations, systematic and random errors that should be considered when interpreting these results. (4) The controlled variables were not tested before this experiment to see if they were working and reliable. Figure 2 heart rate was quite inconsistent and did not follow the pattern of the other results, which maybe suggest a random error with the heat rate monitor. A systematic error could include the fitness of the participants. One of the test subjects is an endurance athlete and the other does not compete in any sport. This would affect the results because for the endurance-trained athlete, from their training they increase their cardiac output results from a substantial increase in maximal stroke volume. In untrained persons, cardiac output increases in response to exercise primarily by an increase in heart rate. The endurance-trained athlete does so mainly by an increase in stroke volume. Simply meaning that although both participants are doing the same cadence and length the endurance athletes skewers the results by already having an increased rate in stroke volume. Another systematic error may include the rate of perceived effort. For the most accurate results, the measured maximum heart rate would be necessary to give an accurate cadence to ride at.

The results of this test show that it provides a valid test to estimate aerobic capacity and shows there is a small measurement of error. A polar heart rate monitor was used to measure the heart rate with a step of 30cm in height with a metronome with a beat at 15 steps, per minute and increased by 5 steps every minute for 5 stages or until 80% of the maximum estimated heart rate was reached. The results demonstrated that the Chester Step technique is a valid predictor of aerobic capacity in males and females from a wide range of ages and fitness levels.

The heart rate is a measurement of how many times the heart beats in a minute. Physically fit people tend to have a lower heart rate and during intense exercise tend to have lower rates as well. A decrease of heart rate at both rest and at fixed intensity of sub-maximal exercise [7] occurs a few months after an exercise program is begun. One’s heart rate reflects the amount of work the heart must do to meet an increase of demands of the body when engaged in activity. Heart Rate tends to increase proportionally with intensity oxygen uptake [16].
