These three tubes acted as our baseline. Tube 1 was used to fill up a smaller test tube which was placed into a spectrophotometer, then zeroed it out. The tube was then removed and cleaned out. Tubes 2 and 3 were mixed together (at this point a stop watch is started) then were used to fill another small test tube. This test tube was placed in the spectrophotometer, every thirty seconds a reading was taken, this continued on for three minutes.
Then divide that time by 12 and multiply by 60. After the resting heart rate is completed, exercise by using a stepping stool or low chair. While exercising, determine how long to exercise to increase the heart rate by 1.7 X the resting rate and rest 5 minutes between exercise bouts. After completing the exercise, attach electrodes tot the recording ECG as soon as possible after exercise and record for 4 minutes. Determine BPM for first 30 seconds in minute 1 of recovery, first 30 second.
Therefore, in this experiment we hypothesized that a male pulse rate would decrease back to its resting state more rapidly than a female’s pulse rate after an exercise regiment. Methods Cardiovascular Exercise. For this experiment we paired off one male and female per each of six groups to do a regimented step exercise continuously for three minutes. The steps were eight inches off the ground and both subjects stepped on and off the ledge at a rate of 30 steps per minute. Pulse Measurement.
Homeostasis is for the procedure of the body to uphold a relatively consistent internal state. The nervous system sends and also receives these signals about temperature, blood pressure, hydration and more factors. The endocrine system tends to carry chemical messengers to adjust all the bodily functions. During different forms of exercise, the body’s internal environment is then changed and placed under a considerable amount of stress. Throughout homeostatic feedback mechanisms, the body is allowed to maintain a very healthy internal environment and then rapidly return to normal after all of the exercise ends.
The purpose of process improvement plan is to increase the workout routine and aid the bottleneck in the process of burning calories. Control limits Control limits are the horizontal line on a control chart that represents a boundary for a process (toolingu, 2011). The total operating time for my workout routine is 20 minutes. The process can be more productive and effective if I add additional 25 minutes every time I used the treadmill. The new operating time is 45
Testing the reaction rate of fermentation based on alterations in ph solutions. Emily Anderson Abstract The experiment was conducted to determine what effect different ph solutions would have on the reaction rate of yeast fermentation. It was hypothesized that, the more acidic a ph solution, the slower the reaction rate would be in fermentation process. The reaction rate was judged by the amount of co2 displacent formed in the top of the fermentation tubes every five minutes for twenty minutes intervols. Introduction When the oxygen supply runs short in heavy or prolonged exercise, muscles obtain most of their energy from anaerobic process called glycolysis.
In your last assignment, you were put into groups of two. Each group had thirty minutes in class yesterday to write a brief explanation utilizing accurate research methods of the step assigned to you. The only restriction given was to avoid the use of any computer-based data. I will explain the reasoning for that in a few minutes. For now, I am going to call out the steps in sequence.
Psy 200 Behavior Modification Program Behavior Modification Summary: The purpose of my goal was to increase my time in studying so I can make better grades on my test. My plan was to take two hours everyday to study, and take more time on my homework. My results were out of three of my classes I passed two of my test. Method: Before beginning my behavior modification program I only studied once or twice a week, and waited to the last minute to complete my homework assignments. My positive reinforcements were if I passed my biology test I would be exempt form my final exam.
Blood Glucose A blood glucose test measures the amount of a type of sugar, called glucose, in your blood. Glucose comes from carbohydrate foods. It is the main source of energy used by the body. Insulin is a hormone that helps your body's cells use the glucose. Insulin is produced in the pancreas and released into the blood when the amount of glucose in the blood rises.
Homeostasis is known as the maintenance of a constant internal environment despite external changes or stimuli in references to exercise. When the muscles in your body contract, the glucose will be used up so in order for the blood glucose levels to be maintained stimuli changes the blood glucose concentrations. Negative feedback increases blood glucose levels by secreting glucagon, the alpha cells in pancreas this stimulates the liver to convert glycogen into glucose, which is then released and absorbed by the cells in the body. Homeostasis is changing to the environment. During exercise our body undergoes a lot of changes.
