Exercise Intensity on Cellular Respiration measured through Heart Rate and CO2 Production Background Research Cellular Respiration: C6H12O6 + 6O2 >>> 6H2O + 6CO2 + 36 ATP When examining the effects of exercise on cellular respiration, we can assess three main bodily functions: carbon dioxide production, heart rate and breathing rate, all telling us of an increase in cellular respiration. We can only directly measure the CO2 output that is a direct result of cellular respiration, we can use all of these fields of measurement to show that exercise uses more or less energy than rest, answering the question. Cellular respiration takes one glucose or sugar (C6H12O6), and six oxygen (6O2) to produce 36 ATP, essentially units of energy and release …show more content…

Hypothesis If a person exercising is working harder, by performing an exercise like running or sprinting, their heart rate and CO2 production will be higher, measured by higher BPM and lower time taken to turn the BTB yellow, than a person who is sitting or walking, because muscles need more energy to perform the more strenuous tasks, and the higher heart rate and CO2 production will indicate a higher cellular respiration rate. Experimental Design IV: Exercise. Sitting, walking, running, and sprinting up the stairs will be an increasing amount of work for the person’s body, showing a trend toward harder work DV: CO2 measured by BTB, HR measured in BPM, both will show increase in intensity and cellular respiration. Control: Sitting person will provide a baseline against exercise …show more content…

This in addition to our current data would help draw more concrete conclusions. Additionally, our BTB CO2 data had many outliers and may have been affected by the intensity at which the exerciser blew, with a difference of 11 seconds for exerciser A’s sitting BTB tests, this data could be improved, possibly by introduce a standard blow rate, with a flow regulator. I observed that by simply blowing harder, the times went down. In addition, a more standard color change should be introduced. We would also benefit from collecting more data from several other exercisers, as half the test group showed an increase in blow time for sprinting, that could be substantiated into something with more

Ninth and Tenth Grade Fitness Analysis During the time that I have taken gym class as both a freshman and a sophomore, I have noticed a change in the scores between each of my four fitness tests. Starting with my ninth grade baseline test, I received 2,000 meters on the twelve minute run, 16 walls on the twelve minute swim, a time of 1:30 for the front plank, 1:15 for the superman, 1:24 for the wall sit, 38 crunches per minute for the crunch test, 10 push-ups for the push-up test, 75 pounds on the bench press, which equaled 50% of my body weight, and -3.5 inches on the sit-and-reach test. During my ninth grade post test, I received 2,200 meters on the twelve minute run, 20 walls on the twelve minute swim, 3:00 for the front plank, 3:00 for

Living or working within 10 miles of one of the Fitness centers. These individuals have hit a turning point in their health/fitness routine, they believe in the idea of fitness, but find it hard to motivate themselves for solitary fitness activities. What sets Orangetheory apart from other fitness centers is that we will master the workout known as Excess Post-Exercise Oxygen Consumption (EPOC); we will provide each customer with a heart rate monitor so they can monitor their 5 zone interval training sessions. During a customer’s 60-minute workout session, they will perform various intervals targeted to produce 12 minutes of training higher than 84% of their maximum heart rate. This product/workout is designed to produce EPOC, which will produce 200-400 calorie increase to the customers’ metabolism 24 hours after their workout.

The 15 second pulse was plugged into the Forestry Non Adjusted Fitness Values tables (there is a male and female table) where participants used their pre-recorded weight and the pulse to converge onto a relative VO2max. This value was then used in the Age-adjusted Fitness Scores for the Forestry Step Test table (there is no separate male and female table) to find the individual's age adjusted VO2max. Finally, this age adjusted VO2max number was used in the Aerobic Fitness Categories in Men (M) and Women (W) for the Forestry Step Test table where the participant's age is used again in conjunction with the previous value to find what fitness category the individual is

The data that my group collected refutes our hypothesis because the difference and inconsistency of the breaths per minute in the ventilation rate and the breath volume in liters are all around the same amount. The p-value from the t-test for ventilation (breaths/minute) was 0.27, and for the breath volume (liters) it was 0.15. Both p-values are above 0.05, the Null Hypothesis is accepted. There is an overlap of data. The answer to the previous question is yes, mild and vigorous exercise affects the ventilation rate the same way as breath volume rates with little to no difference.

Cardio Respiratory Endurance Cardio Respiratory Endurance is the ability for the heart and lungs to supply oxygen to the body for a prolonged period of physical activity. The area of the body that this takes place in is the cardiorespiratory system (subsists of the heart, blood vessels, and respiratory system). The bellow figure shows the cardiorespiratory system. I tested my Cardio Respiratory Endurance by doing the beep test. As a result, I achieved an average score of 8.5.

Abstract The purpose of this experiment is to test for mitochondrial activity by isolating different organelles using the differential centrifugation process. Studying mitochondria is extremely important because they control the death and life of the cell by regulating the apoptotic signals (Frezza et al 2007). Also they are responsible for the metabolic reactions (aerobic respiration) and the production of ATP (Frezza et al 2007). Three hypotheses were formed based on my knowledge.

The Effect of Sugar Concentration on CO2 Production by Cellular Respiration in Yeast Introduction In this lab, our main focus was to find how sugar concentration affect yeast respiration rates. This was to simulate the process of cellular respiration. Cellular respiration is the process that cells use to transfer energy from the organic molecules in food to ATP (Adenosine Tri-Phosphate). Glucose, CO2, and yeast (used as a catalyst in this experiment) are a few of the many vital components that contribute to cellular respiration.

we have a tendency to count our calorie intake, the calories we have a tendency to lose on a treadmill, etc. However, simply dynamic our thoughts regarding our physical activity looks capable of adjusting our bodies. chamber attendants clean on the average fifteen rooms per day, every area taking between twenty and half-hour to complete. (The physical activity concerned meets the MD General’s recommendation of a minimum of half-hour of physical exertion per day for a healthy mode.) However, most chamber attendants believe that they are doing not get regular exercise; and lots of them believe that they are doing not get any exercise in any respect.

An organ bath experiment was conducted to investigate the effect of agonist, histamine on guinea pig ileum (GPI) and how the antagonists, mepyramine and SIPBSDrug A affect the GPI’s response (smooth muscle contractions). A GPI simulation was conducted to compare the potencies and nature of antagonists against histamine. The control Rmax and EC50 of histamine without antagonist were 16.49gms and 2.093 x 10-7M respectively. The concentration-response curves were shifted to right parallelly and EC50 increased while Rmax remained constant when mepyramine or SIPBSDrug A was added. Besides, both antagonists showed linear graphs in Schild plot, indicating that they acted as reversible competitive antagonists.

Cellular Respiration One of the main essentials of life that all organisms need in order to function in our world is, energy. We receive that energy from the food that we eat. Cellular respiration is the most efficient way for a cell to receive the energy stored in food. In cellular respiration, a catabolic pathway, which breaks down the molecules into smaller units, in order to produce adenosine triphosphate, also known as, ATP. ATP, is used by cells in the act of regular cellular operations, it is a “high energy” molecule.
