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 purpose of this lab was to better understand the human body by doing various activities and observing the three different muscle types. The activities were not conducted in order, but we did follow the instructions of each activity. However, there could be deviation since Vivian had allergies and I was sort of sick as well so our result may not be as accurate. By conduction the activities, we were able to analyze the different receptors in the skin and sense—for instance understanding the differences in receptors or taste and smell. Also, we were able to differentiate the three muscle types and observe the striation of the cardiac and skeletal muscle—and observe other differences in muscle types. By noticing that, for instance the tongue has different regions for different taste, we were able to infer that some taste are more important to distinguish than others. Also, by observing the different types of muscle, we were able to discuss the different functions and why the cardiac and skeletal muscle have striation. Lastly, it is important to understand the human body, not

In addition, heart rates vary according to exercise, physical needs, age, gender, air temperature, etc. In this experiment the dependent variable

The respiratory monitor measured baseline respiration for a minute. Respiratory rate was also measured by the respiratory monitor throughout the entire experiment. After initial respiratory rate had been measured for about 30 seconds, researchers established a baseline heart rate range using the pulse oximeter. This was done by recording maximum and minimum heart rates within a period of 30 seconds. Since the site of the experiment had abundant background noise, silence could not be used as the control variable. Therefore, white noise was used as the control instead. The subjects listened to “Original White Noise” by White! Noise using Sony MDR7506 Dynamic Stereo Headphones. The subject was instructed to pedal at a rate between 8 and 10 mph and was supervised by an experimenter to ensure that the participant stayed within the proper pedaling speed range. As the participant pedaled, the researchers changed the resistance on the stationary bike between resistance levels 8 and 11 to make sure that the participant’s heart rate was within the preferred range. Subjects were monitored to ensure they had the heart rate ranges of 55-65% of his or her age-predicted heart range. The subject pedaled for two minutes,

From the lab, “What happens in my body When I run Around school?” I learned that exercising causes chemical reactions inside the human body. Me and my peers did all this to see what's going on after someone has worked out and reactions. We also took data on what goes with somebody's body before exercising and after exercising. Also different kinds of energies that go on with the experiment we did. In addition is the differences in the data like if the skin temperature if it went up or down from the one before.

Before we began the physical activity, we measured the tests subjects heart rates after ten minutes of rest, sitting on the floor. Judging that a pulse of 60 to 100 beats per minute is seen as average (allowing room for age and physical condition to factor in), we can see that the test subjects all have what is deemed to be a normal heart rate, Tests One and Two having pulse rates in early 80s whilst Test Three have a pulse in the high 90s. This means the average pulse rate for our subjects was 87 beats per minute. The normal respiration rate for an adult at rest is 12 to 20 breaths per minute, showing that Test One has a breathing rate higher than expected, Test Two being only slightly higher and Test Three showing the optimum breathing rate

The procedure taking place is measuring the rate before and after the exercise. first , the heart rate at resting will be recorded for ten seconds then multiplied by six. The heart rate will be measured before exercise because the heart rate after exercise will need to be compared to it. Next on the procedure, the data that has been collected so far will have to be recorded. After recording the data, proceed by starting the stopwatch for two minutes. When the timer is ready start the exercise which being jumping jacks. After the two minutes are up, stop doing jumping jacks and start to measure the heart rate. The pulse will be counted for ten seconds, then multiplied by six to end up with the heart rate. After the heart rate is found after

I did the 1 mile walk and my time was 17 minutes and 26 seconds. My heart rate at the end of my walk was 100 bpm. My VO2 max was a 48.72 and for my people are around my age that just ranked in the category of just good.

2. With the point of a pencil or pen, make a slight indentation on the lips. Remove the pencil and have the subject (with eyes still closed) indicate the point of stimulation with another pencil. Measure the error distance in mm. Repeat for the same stimulus point. Is there improvement with repetition?

(Interactive science) (bbc.co.uk) Apparatus - Gear fit 2 watch (I have one in my house). You need this watch so I can measure the amount of time spent exercising and also the heart rate prior and posterior exercising. - A treadmill. For an experiment about the duration of time spent on a treadmill and heart rates we are obviously going to need a treadmill to run on.

PURPOSE: This laboratory’s main goal was to properly conduct a maximal treadmill test, which included accurate and proper measurements of certain cardiovascular fitness markers. These included heart rate, blood pressure, and the RPE during exercise.

The experiment began by taking the height and weight of all of the participants. Those taking part performed two trials on separate days. For the first trial, participants consumed water at leisure throughout the day, then at 3:00 pm, preceded to the gym to begin the experiment. Before exercising, the first participant placed the Suunto brand heart monitor under their shirt on their breastbone and fastening the display watch on their right wrist. The participant’s heart rate was recorded before beginning the exercise. The wattage of the Precor RBK 835 Recumbent exercise bike was then set to 80 watts and the participant rides the stationary bike at an intensity that maintains the wattage range between 80 and 90 watts. After five minutes of riding,

Once the first sip of the cup of coffee was consumed, a one-hour alarm was set for that individual person. After a full hour had passed, their pulse was measured as well as their diastolic and systolic blood pressure using a simple arm cuff. Participants were separated from one another to keep the results confidential and were not allowed to discuss the experiment with each other. After their pulse and blood pressure was taken, each participant was weighed, as well as asked personal questions such

First we found out the resting breathing rate of the individual before we did any exercises, this was done by the own individual by counting his own breath in a minute before the exercise making sure his heart is at a resting state. This exercise was also done after

To obtain the most accurate reading, the device must be placed directly over the heart where the heart pulse and respiration expansion will be the greatest. There are many different ways to secure this device to the body. It has been decided the best way to secure the device onto the body is to secure the device onto nylon which will be wrapped around the person’s chest and strapped on the back. The nylon will fit itself onto the person’s body to obtain an accurate reading with minimum outside interference even when the user is active. The components of the device must move
