Abstract:The purpose of this experiment is to see if the number of times somebody closes a clothespin increases with or without exercise.It is our hypothesis that if you rest first then you should be able to squeeze clothespin more times in one minute then squeezing the clothespin with exercise. In our experiment one person exercised for two minutes and then squeezed the clothespin, then after the one minute they rested then squeezed the clothespin. Our hypothesis was proven correct since the person squeezed the clothespin more after he rested.

•While exercising your lungs tries to increase the intake of oxygen as well as release the carbon dioxide.
Hypothesis: If you rest first, then you will be able to squeeze a clothespin more times in one minute.
Materials
•Timer
•2 clothespins
•One person
Procedure
Step 1:Get a timer, 2 clothespins, and 1 test subject
Step 2:Let the test subject do jumping jacks for 2:00 minutes.
Step 3:Set a timer for one minute.
Step 4:Make sure the person holds the clothespin between their thumb and index finger and squeeze until the two ends meet.
Step 5:Start timer and have the person squeeze the clothespin for one minute.
Step 6:Record how many times the clothespin was squeezed.
Step 7: Then let the person rest for 2:00 minutes
Step 8: Repeat steps 4 through 6
Step 9: Compare the data from both trials
Step 10:Repeat experiment to get more accuracy
Variables:
Independent Variable- The person resting
Dependent Variable- How many times the person squeezes the clothespin
Control Variables-the time of rest and exercise, condition of person both times
Control Group-the people that are resting
Results:
Results after Resting Results after Exercise

The only other strength of the experimental design was that its validity was reasonably high. This experiment directly tested the effect of prior exercise on muscle fatigue during physical exercise
The contraction of the inspiratory muscles increases the volume of the thoracic cavity causing the pressure within the alveoli to decrease and air to flow into the alveoli. During resting inspiration, the diaphragm, the external intercostals and the parasternal intercostals contract to stimulate inspiration. During forced inspiration the scalene and the sternocleidomastoid muscles contract to further expand the thoracic cavity. The pectoralis minor muscles also play a minor role in forced inspiration. During quiet breathing, relaxation of these muscles causes the volume of the thoracic cavity to decrease, resulting in expiration. During a forced expiration, the compression of the chest cavity is increased by contraction of the internal intercostal muscles and various abdominal

The reason why is that exercising gets your blood pumping which brings more oxygen to your muscles. According to table #1, it can be seen that most of the numbers under the difference column are positive which means that these people’s squeezing rate increased when they exercised first. Based on graph #1, you can see that more people increased by the height of the bar. Both the table and the graph support that if a person exercises first , he/she will be able to squeeze a clothespin more times in a minute than a person who rests
In this lab, we explored the theory of maximal oxygen consumption. “Maximal oxygen uptake (VO2max) is defined as the highest rate at which oxygen can be taken up and utilized by the body during severe exercise” (Bassett and Howley, 2000). VO2max is measured in millimeters of O2 consumed per kilogram of body weight per min (ml/kg/min). It is commonly known as a good way to determine a subject’s cardio-respiratory endurance and aerobic fitness level. Two people whom are given the same aerobic task (can both be considered “fit”) however, the more fit individual can consume more oxygen to produce enough energy to sustain higher, intense work loads during exercise. The purpose of this lab experiment was performed to determine the VO2max results of a trained vs. an untrained participant to see who was more fit.
The purpose of the experiment is to determine the ID of an unknown diprotic acid by establishing its pKa values. The first phase is to determine the unknown diprotic acid by titration, which is a technique where a solution of known concentration is used to determine the molecular weight. While the second phase involved seeing how much NaOH needed to standardize diprotic acid.
During the early parts of exercise odour breathing rate increases and if that increases then always our tidal volume increase but during steady state excise they start to plateau off and therefore our respiratory centre that is found inside our medulla so as soon as our breathing rate plateaus our tidal volume will do the same thing and plateau off.

During the first one or two minutes of exercise, before the heart has pumped enough oxygenated blood to the working muscles, the muscles are powered by anaerobic energy. In order for these muscles to continue exercise, the body must supply them with continuous supply of oxygen, the more efficiently this is done, the better the cardiovascular fitness level. During cardiovascular conditioning, a program such as interva...
As the exercise intensifies, you need more energy and therefore more oxygen. Your blood carries oxygen from the lungs to your muscles. To keep up with these increased oxygen needs, you have to have more blood going into your muscles. As a result, your heart pumps faster, sending more oxygenated blood to your muscles per second. Aim-

Aerobic exercise involves improving the cardiovascular system. It increases the efficiency with which the body is able to utilize oxygen (Dintiman, Stone, Pennington, & Davis, 1984). In other words, aerobic exercise means that continuous and large amounts of oxygen are needed to get in order to generate the amount of energy needed to complete the workout. The most common type of aerobic exercise is long-distance running, or jogging. While running, the body requires large amounts of energy in order for the body to sustain energy. “During prolonged exercise, most of the energy is aerobic, derived from the oxidation of carbohydrates and fats” (Getchell, 1976).
One of the most important changes would be an alteration in the concentration of hydrogen ions in the blood, this could be caused by a rise in blood carbon dioxide or an increase in tissue respiration in the muscles during the exercise. The respiratory centre is in its self. sensitive to raised hCo2 and responds by increasing the rate and depth. of the breath of the mind. In the aortic arch and carotid bodies there are chemoreceptors.

Adding exercises into one’s daily routines can change their whole lifestyle. Many people look at exercise as being something just for people who want to lose weight or to become muscle bound, but there are a great deal of benefits that can be received from exercising regularly. Of course gaining muscle and losing fat are the two most popular reasons that usually attract people to the gym, but they make up a small part of the potential benefits that can be achieved with exercise. There are several ways in which I have benefited in my life from exercising regularly, besides just making me bigger and stronger. It has made me become more organized, helped me make better decisions, and motivated me to take on new challenges in life.
