Blb Experiment

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.

1. Explain the change in ERV with exercise. the ERV decrease with exercise asssuming that the volume of air was exhaled more than being enhaled at the time. 2. Explain the change in IRV with exercise. IRV decreased as well because the amount of air that was supposed to be inhale was very little inhalation during the time of exercising. 3. Explain the change in IC with exercise. IC increase with exercise beacause the subjects were able to allow their lungs to breath. 4. Explain the change in FRC with exercise. The FRC decrease just a little with exercise. 5. Explain why RV does not change with exercise. the ERV decrease with exercise asssuming that the volume of air was exhaled more than being enhaled at the time. 6. Explain why VC does not change with exercise. the vital capacity remain the same because it accumulated the tidal

This experiment was carried out as noted about in Procedure 1. The resting heart rate was established and used as a baseline value from which to compare all future deviations. While data could

In addition a small rise in breathing rate and this is called anticipatory rise, this happens when exercising. The average reading for breaths per minute during exercise is 23-30. This shows that with more blood pumping through the body more oxygen is needed to keep the body at a sustainable rate to help our body create more energy. Our breathing rate will keep increasing until

Using the lab activity, observe and record the physiologic changes that occur during exercising using the following chart:

7. After obtaining 10-20 seconds of stable heart rate values, rise rapidly to a standing position. Continue to record until the baseline heart rate has been achieved or until the end of the run. Data will be collected for 400 seconds.

The effects of heart rate on differing durations of exercise were studied in this experiment. For people, heart rate tends to increase as they perform physical exercises. The amount of beats per minute gradually increases as people perform physical activities. Heart rates taken before exercise are relatively low, and heart rates taken one minute after exercise increase significantly. Heart rates slowly begin to decrease after they are taken two minutes and three minutes after performing the step test, which is to be expected. The rates of intensity throughout exercise relates with changes in heart rate throughout the step test performed in the experiment (Karvonen 2012). The age of the participants affected the experiment, since the heart rate during physical exercise, in this case the step test, is affected by age (Tulppo 1998).

Being knowledgeable about the heart is very important, especially if one is an athlete. This experiment is significant, because it can tell us how important it is for one to keep their heart healthy. It will also tell us how playing a sport can benefit one’s health and the well being of their heart. Our hypothesis says, if the athleticism of a person increases, then the heart rate recovery time will decrease when heart rate recovery in a function of athleticism. The purpose of this project is to see which type of athlete, or non-athlete has the best heart function.

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 conceptual overview, along with the experimental procedures are found in the NPB 101L Physiology Lab Manual 2nd Edition. More specifically, pages 55 to 63 provided a full insight to all the experiments in the respiratory lab. In addition, a list of required materials was given for every experiment. The authors of this lab manual were Erwin Bautista and Julia Korber. As for data acquisition, the BIOPAC software was used to collect and record data for all the trials. Furthermore, the teaching assistants had calibrated each station prior to initiating the lab exercises. For the entirety of the respiratory lab, a human subject was used in all the experiments. A 22-year-old female was the participant for the first two experiments regarding

The measuring of flow-volume loops (FVL) in laboratory settings during exercise are becoming increasingly popular to identify the limiting mechanics of ventilation (Johnson, Beck, Zeballos & Weisman, 1999a). The collection of a maximum flow-volume loop (MFVL) through a forced maximal maneuver at rest allows researchers to compare a baseline value with tidal loops obtained during exercise (Johnson et al., 1999a). Dominelli and Sheel state that MFVL provides information on an individual’s capability to produce volume and flow with respect to their mechanical ceilings (2012). Placing the respective tidal loops associated with different exercise intensities within a resting MFVL shows the difference in volumes during exercise and rest. An MFLV maneuver would yield the largest loop; whereas, the resting tidal loop would be the smallest (Johnson, Weisman, Zeballos & Beck, 1999b). Additionally, tidal loops during exercise will fit somewhere between resting and maximal tidal loops; increasing in volume as intensity increases; however, the loops still remain small in comparison to the MFVL (Johnson et al. 1999b). This aforementioned trend observed in healthy individuals during increasingly intense exercise is related to the lack of constraints on ventilation (Johnson et al. 1999b). Major factors responsible for limiting ventilation at rest and during exercise are bronchodilation and bronchoconstriction; these in turn affect total lung capacity (TLC)--a key measure with

The effects of exercise on blood pressure, heart rate, respiration rate and electrical activity of the heart were assessed. The measurements of respiration rate, pulse rate and blood pressures were noted as described in Harris-Haller (2016). Data was first taken from subjects in a relaxed position and then followed by sets of reading after exercising based on one minute intervals. The data also noted sitting ECG traces from Harris-Haller (2016). The respiratory rate, pulse, blood pressure, P wave, QRS complex and T wave were defined for each subject. The class average was calculated for males and females and graphed to illustrate the results by gender for each cardiopulmonary factor.

Aim: To investigate the relationship between exercise levels and respiratory functions. Hypothesis: If respiratory functions are measured after different exercise levels are completed, then there will be an increase in those functions which include heart rate, breathing rate and carbon dioxide production levels. Materials: Test tube rack Safety glasses

As the intensity of exercise increased, so did the rates of the heart and breathing. After a small period of rest, the heart rate and breathing rate both decreased to a point close to their resting rate. This proved the stated hypothesis. First, the hearts average resting rate was recorded to be 76 bpm. The heart is therefore transporting oxygen and removing carbon dioxide at a reasonably steady rate via the blood. During the low intensity exercise (Slow 20) the heart rate increases to 107 bpm, which further increases to 130bpm at a higher intensity level (Fast 20). The heart therefore needs to beat faster to increase the speed at which oxygen is carried to the cells and the rate at which carbon dioxide is taken away by the blood.

Carry out an experiment to measure the heart rate and ventilation rate before, during and after moderate exercise.
