The Effect of Exercise on Pulse Rate
In this experiment I am trying to find out how exercise affects my
pulse rate. I will do this by exercising then measuring my pulse rate.
In this experiment I will use 2 pieces of equipment, a stopwatch and
calculator. I will use the stopwatch to time how long I exercise for
and the measure my pulse rate and I will use the calculator to work
out my pulse rate.
I will first exercise for 15 seconds then measure my pulse rate for 15
seconds then rest for 2 minutes then repeat the process. I will do
this 3 times then increase the amount of time I exercise for to 30
seconds and do the same but exercise for 30 seconds. I will increase
the amount of time I exercise for by 15 starting from 30 then,
45,60,75 and then 90 seconds. I will make sure results are reliable by
repeating them if they are slightly unreliable.
I predict that as the amount of time I exercise for increases so will
my pulse rate.
To make sure the experiment was safe I moved away all the chairs,
tables etc around the area I was exercising in so I would bump into
anything. Also I made sure I made sure the clothing I was wearing was
suitable to the exercise I was doing.

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
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.
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.
Internal Assessment The relationship between recovery heart rate between athletes and non-athletes. Lab Design:.. Research Question: What is the effect of practicing aerobic sports on a daily basis, on the recovery heart rate of people? Hypothesis: If a person practices an aerobic sport on a daily basis (athlete), then he will have a higher recovery rate due to the fact that their heart is more accustomed to intense physical exercise than someone who is not (non-athlete).

The Effects of Body Position On Heart Rate Introduction: Your heart rate (HR), is the number of times that your heart pulses in a minute. Resting heart rate varies from person to person. Several factors can influence a subject’s heart rate including activity level, body position and other factors such as air temperature, or medication use. [1] Resting heart rate can be affected by body position, due to gravity having varying affects on the heart in different positions.
Introduction: In year 10, biology, we have been studying the heart: the functions of the heart, the parts of the heart (ventricle, atrium) and heart problems. Besides that we have been studying the heart rate of humans. We were asked to create an experiment to see what affects heart rate. We discovered that diet, stress, cholesterol level, excitement, mass, age, temperature and exercise affected the heart. Diet and exercise were the only 2 doable and so my partner and I chose exercise. We determined that as the intensity of an exercise increased so did the heart rate of the person performing it.
The heart is an extraordinary structure that is the base of all human life. However, it similar to the uncomplicated functions of water pumps. As the heart beats, blood is distributed throughout the body using a network of blood vessels. The functions of the heart can be kept in regular and healthy conditions through exercise. Exercise has an effect on the blood that is circulating through the body. That circulating blood makes the heart desire more oxygen, causing the heart rate to increase rapidly to keep up with activity demand.
In this report, I will be writing about the data that was collected from the beep test, which tests the aerobic endurance of the participants who are performing the test. With the results collected I will be discussing the different factors that may have impacted on the participant’s results. Robinson (2010) states that there are different systems in the body such as the skeletal, muscular, circulatory, and respiratory. Despite the fact all these systems are separate, they are all linked together to help the functioning of the body when at rest and during exercise. When the body begins to participate in exercise, during physical activity changes start to occur in the cardiovascular system starts so that it can adapt to the physical activity, this links into Kenney et al, (2012) where they indicate that cardiovascular changes occur when the body starts to move during exercise, and that the main reason for this is so that the blood flow increases to the working muscles. Furthermore, there are other adjustments in the cardiovascular system, where the ‘blood flow patterns change significantly in the change from rest to exercise. Through the vasoconstrictor action of the sympathetic nervous system on local arterioles, blood flow is redirected away from areas where elevated flow is not essential to those areas that are active during exercise, only 15% to 20% of the resting cardiac output goes to muscle, but during high-intensity exercise, the muscles may receive 80% to 85% of the cardiac output.’ (Kenney et al, 2012:190)
The materials used: one wristwatch (with second hand), two variably indifferent humans (one male, one female), and a standard staircase at CCC. The method was simple: two test subjects were exposed to two trials involving one minute of physical activity and x minutes needed for the recovery of the heart rate. Before the experiment began, each subject's resting heart rate was taken. This would become the controlled variable. Next, each subject ran up one set of stairs at CCC, one stair at a time, for one minute. After one minute of activity, the subjects stopped and began taking his or her heart rate.
As seen in the processed data table, as the intensity of the exercise increases, so does the participant’s heart rate. The graph also supports this by demonstrating that the two variables have a close positive and linear relationship. The data points are close to the trendline which has a positive gradient of 0.3839. The r2 value of 0.9791 is very close to 1, meaning that it has a strong positive relationship. The value also shows that the two variables have a positive correlation in which one variable increases as the other also increases, which supports the other data collected. Furthermore, the error bars on the graph displays the standard deviation of the data points. At an intensity of 140 metronome bpm, the standard deviation

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.
