The Effect of Exercise on Heart Rate
Aim: In this investigation I am trying to find out if exercise have
any effects on the heart rate.
Prediction: For my prediction, I predict that as the amount of
exercises increases, the heart rate will increase too.
Background: More energy (Oxygen and glucose) is needed to pass to all
different kind of muscles as you do a certain amount of different
exercises, so more blood is needed to run in the circulatory system,
therefore the heart rate will go up.
Variables: The results can be affected by the following things, the
change of amount of exercises, the change of time for exercising and
resting, the change of temperature and the change of person and their
health.
Input variables: The input variable will be the time of exercises.
Output variables: The output variable will be the results of heart
rate.
Fair test: To make this experiment a fair test, I will set out a table
for different times I'm testing on, only choose one exercise and use
the same person for the experiment all the way through.
Apparatus: In this experiment the apparatus I will be needed is a
stopwatch, a pulse watch and some steps (e.g. Stairs).
Method: 1) At the beginning of the experiment, we will take down the
pulse from the person who is experimenting and note it down.
2) Firstly we do the exercise we have chosen for 2 minutes, than we
take down the pulse rate and note it down while they are resting after
exercising. We do that 3 times.
3) We do the same for the other sets of minutes, 4 and 6 minutes, and
at the end of each set were all measured, we will calculate the
average and note it down into the table of results.
Safety: To make this investigation safe, we can not force the person
who is doing the experiment to do over-exercising, or to force some
one who has breathing problems to do long exercises.
2.The control group will rest for two minutes and the experimental group will exercise for two minutes. The experimental group will exercise by doing jumping jacks.
The results of this experiment are shown in the compiled student data in Table 1 below.
Cardiovascular Activity And How it Influences the body. Introduction: Cardiovascular fitness is a form of aerobic fitness (Neporent and Egan 1997). There are many different ways of evaluating the amount of oxygen used during cardiovascular fitness and one the methods involved is called VO2 Max. VO2 Max is the maximum amount of oxygen that the body can hold.
Currently, it is not possible to prescribe isometric exercise at an intensity that corresponds to given heart rates or systolic blood pressures1. This might be useful in optimizing the effects of isometric exercise training1. According to further study on this topic, linear relationships that have been discovered could be used to identify isometric exercise training intensities that correspond to precise heart rates or systolic blood pressures. Training performed in this way might provide greater insight into the underlying mechanisms for the cardiovascular adaptations that are known to occur as a result2. Studies have also shown a direct, strong, independent and continuous relation between blood pressure and cardiovascular mortality without any evidence of a threshold down to at least 115/75 mm Hg3. Further, it has been demonstrated that, as compared with optimal BP, normal and high-normal BP are associated with a higher incidence of CV disease3.
Sport aerobics is a new exiting performance sport, and like any new sport, is seeking recognition and acceptance as a valuable and worthwhile competitive activity. It is said however, that Sport Aerobics will always struggle for popular support because of pre-existing stereotyped views of sport in Australian society. The purpose of this essay is to challenge stereotyped views of sport in Australian society in order to increase participation in Sport Aerobics. To do this a proposed strategy will be implemented at Nambour High School to challenge stereotyped views of sport and breakdown social barriers to the participation in Sport Aerobics. This strategy involves including Sport Aerobics as a compulsory activity in the junior school physical
I have chosen to vary the concentration of the enzyme catalase, as it is simple to do in the laboratory, and will obtain easy to interpret results. Therefore, all the other variables will be kept constant to make sure the experiment is fair. Keeping the experiment fair: All of the variables with the exception of the concentration of catalase will remain the same, to make sure that the results obtained are not influenced by anything other than the concentration.
Results: The experiments required the starting, ending, and total times of each run number. To keep the units for time similar, seconds were used. An example of how to convert minutes to seconds is: 2 "minutes" x "60 seconds" /"1 minute" ="120" "seconds" (+ number of seconds past the minute mark)
The main components of the human cardiovascular system include the heart and blood vessels. The heart beats in order to pump blood to the vessels which are responsible for circulating it to cell tissue throughout the body. During the homeostasis process, the circulatory system provides oxygen and nutrients to the cell while removing waste products from the tissue fluid such as carbon dioxide within the lungs. This process is required for cell function.
To make sure it is a fair test; the procedure is repeated a couple of
we cant just look at one variable if we want it to be a fair test
Some hypothesize that moderate levels of exercise will decrease the symptoms of mental health conditions (Blumenthal et al., 2007; Diaz & Motta, 2008; Motta, Kuligowski, & Marino, 2010; Rosenbaum, Nguyen, Lenehan, Tiedemann, van der Ploeg, & Sherrington, 2011) and therefore be used as an alternative or complimentary treatment option for mental health (Libby, Pilver, & Desai, 2012).

Fair test (how): I made this a fair test by only changing one thing in
Ties and hair should be tucked out of the way, so they do not make contact with any of the chemicals. It would also be preferable to wear a scientific apron, however this is not essential. We should also try our best not to spill any chemicals, and we must not eat or drink in the lab while dealing with these harmful chemicals, as they can get on our hands. Fair Test To make this experiment a fair test, we need to make sure we do a number of things. In this experiment we are trying to find the rate of reaction using concentration as a factor, so there are a number of things we need to make sure we do to keep it a fair test.
