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.
For this experiment, you will add the measured amount of the first sample to the measured amount of the second sample into its respectively labeled test tube then observe if a reaction occurs. In your Data Table, record the samples added to each test tube, describe the reaction observed, if any, and whether or not a chemical reaction took place.
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.
To make sure it is a fair test; the procedure is repeated a couple of
The results of this experiment are shown in the compiled student data in Table 1 below.

Background ---------- Respiration is the process of converting glucose into energy; it is not breathing in and out, as is often believed. Energy is needed for growth, repair, movement and other metabolic activities. The energy released from glucose in respiration is used to produce the chemical adenosine triposphate. Adenosine triposphate is where the energy released during respiration is stored for future use.
The fair testing will be carefully checked so the results do not come out to be void. The light intensity will be changed for it is the only variable used in the experiment. Though the temperature, watt of the bulb, amount of water, size of the plant and posit...

The Effect of Exercise on Pulse Rate What is a Pulse In Physiology, a pulse is where there is a recurring opening out of the biggest blood vessels (Arteries). This is a consequence of a coherent flow of blood being propel around the body. The muscle that is responsible for this surge of blood is the Heart. I know that by taking 220 and subtracting your age you can find your maximum pulse rate, because your muscles rely on oxygen it is important that I understand how oxygen is transported to the bodies cells.
AIM: - the aim of this experiment is to find out what the effects of exercise are on the heart rate. And to record these results in various formats. VARIABLES: - * Type of exercise * Duration of exercise * Intensity of exercise * Stage of respiration
Throughout this investigation, I will be conducting a number of experiments to help solve whether or not heart rate is affected by exercise. My aim is to identify the difference of every volunteer’s heart rate and take down how old they are so I can evaluate whether or not the age of a person make a difference in their bpm (beats per minute).
Investigating the Effect of Exercise on the Heart Rate Introduction For it's size the heart has the huge capacity of pumping large amounts of blood, in the average adult's heart beats 60 to 100 times a minute, pumps between 70ml and 100ml of blood with each beat, circulates 5 to 6 litres of blood around the body per minute and about 13 litres of blood per minute during vigorous exercise. The heart will beat more then 2.5 billion times during an average lifetime. This investigation will be looking at the effect of exercise on the heart rate. Aim The aim of this investigation is to find out how exercise affects the heart rate, using research & experimenting on changes and increases in the heart rate using exercise. Research â— The heart The normal heart is a strong, hardworking pump made of muscle tissue.
