The Effect Of Exercise On The Co2 Output Of A Chocolate Lab Report

Oxygen debt in the muscles is reached when oxygen levels are much lower than required during strenuous physical activity, causing lactate fermentation to occur in the cells leading to muscle fatigue. The results found in the experiment were the number of squeezes in the first trial for the dominant and non-dominant hands were significantly higher than the remaining ones. The results also showed as the trials continued, the number of muscle contractions decreased steadily which supported the hypothesis. However, there were some increased numbers for the dominant hand from trial 4 to 5 and trial 9 to 10. The non-dominant hand expressed similar unexpected results from trial 6 to 7 and trial 9 and 10. The reasons for these results might be due to the finger muscles being worked at the high intensity for a long period of time causing the muscles to consume higher amounts of oxygen thus producing more ATP production. This would cause the muscles to create more contractions towards the end of the trials. The unexpected results could also be caused by experimental errors such as faulty clothespins. The springs connecting the two ends of the clothespin was tight causing the number of contractions as the trials progressed having a more significant decrease. This is because the amount of energy required to open and close the clothespin would be higher, causing the lactate threshold to occur quicker. Due to this, the number of squeezes would decrease drastically as the trials progressed, in contrast to if the springs were normal. This would change the results by the difference between the trials not being evident therefore, not demonstrating the effects of muscle fatigue. Another factor that altered this experiment was the participant’s condition, Palmar Hyperhidrosis –excessive sweating on the palms – which

This report will discuss the work of the energy interplay system in relation to a subject’s result in the 20 metre beep test . Energy system interplay refers to the work done by the three energy systems (ATP-PC, Anaerobic and Aerobic) to provide the body with the necessary amount of adenosine triphosphate (ATP) to complete certain physical activities depending on their intensity and duration.

To start this experiment, set up the gas collecting apparatus. To start Part A, add approximately 15mL of distilled water to the test tube and record the temperature. Use about half of an Alka-Seltzer® tablet and record the mass. Close the test tube with the stopper with the tubing and tilt the test tube so the water and tablet react. When the reaction is finished, record the volume of CO2 recovered by lining the meniscus of the graduated cylinder up with the water level.

In this assignment I will be reviewing the different effects of exercise on the body system including the acute and long term using the pre-exercise, exercise and post-exercise physiological data which I collected based on interval and continuous training method. I will also be including the advantages and disadvantages of these, also the participants’ strengths and areas where they can improve on.

6. Resting and exercising CO – a. What was the average resting CO? 4.9 b. What was the average exercising CO? 14 c. The range of normal resting CO is between 4.2 L per minute and 5.84 L for these subjects. Did average CO increase, decrease, or not change with exercise? increase

In the experiment, the hypothesis that was made stated that cellular respiration would occur faster with addition of exercise. Given the data that was presented via the lab, our group was able to conduct that this hypothesis was proven correct, with all of our groups speed of color change speeding with the addition of exercise. This occurs because when the body is exercising the cells need a higher amount of oxygen in a

8) Make a graph of heart rate and breathing rate (please put both sets of data on the same graph) versus time after exercise. (from lab paper)

Then, setup up your CO2 gas sensor to the low (0-10,000ppm) setting. After that you will connect the O2 gas sensor to channel one and the CO2 gas sensor to channel two to the lab quest. Next, choose new from the file menu. With a thermometer measure the room temperature and record it. Now, gather 35 germinated peas and set them dry with a piece of paper.

A Comparison of Total Caloric Expenditure and Respiratory Exchange Ratio in Different Modes of Exercise

The procedure for this experiment was to first obtain four balloons and blow them up in order to stretch them. Then obtain and fill the four large test tubes each with thirty milliliters of warm forty degrees Celsius water and two grams of dry yeast which was weighed on a scale and scooped out by a spatula. After five milliliters of water, ten percent glucose, fructose or sucrose went into one of the four test tubes. Then parafilm was placed on top of each of the test tubes to seal them and they were swirled activating the yeast through rehydration. After swirling the film was removed and the balloons were tightly placed on the test tubes. Then finally observed the tubes build up of CO2 all the while swirling gently every fifteen minutes, recording observations.

The objective of this report is to critically explain the physiological effects of exercise on the human respiratory system and cardiovascular system. To begin with, I will explain the two systems, their specific functions and how they inter-relate. I will then go on to analyse the effects of exercise on the two systems by looking at the way in which the body deals with an increased workload, and any health issues that may affect this.

Mammals consume oxygen and produce carbon dioxide as part of their metabolism process in order to maintain body functions. This occurs at all times, both rest and during intense work, within mammals. During times of greater work, skeletal muscles work harder than they do at rest. This in turn increases their metabolic rate and results in a greater demand for oxygen. It has been proposed that fitness training has a positive effect on both the cardiovascular and respiratory systems, which effect the maximum oxygen consumption rate during intense exercise periods. I hypothesize that individuals who aerobically exercise a minimum of at least 7 hours per week will have increased fitness, which will maximize their overall metabolic rates and give them higher VO2 max and VCO2 max values than individuals who do not have increased fitness. Ten males having different fitness levels were put on stationary bikes at increasing levels until exhaustion and VO2-max and VCO2-max was then measured from each individual. It was found that there was a slight upward trend between fitness-VO2max and fitness-VCO2max, although this trend was not statistically significant when represented by the T-test values through statistical analysis. Further experiments should be done in the future to verify a statistically significant correlation.

An athlete needs to ensure that they consume enough fuel to complete activities undertaken. The amount of energy required depends on many factors including size and weight of the athlete, level and intensity of the training, and due to this the amount of energy required varies from person to person. However if more energy is consumed than required, the excess is stored as fat and weight will increase, on the other hand if insufficient energy is consumed the body calls upon its stores to meet the demand and weight will be lost.
