  1. The effect of exercise on pulse rate

    I am going to measure my pulse rate for the first 2 minutes and note it down. I will then continue to measure my pulse rate in 2-minute periods and then see how long it takes for my pulse rate to recover. I will measure my pulse rate using my index finger and my middle finger at my wrist. I will put my results into a table and transfer them onto a graph. I will put a line of best fit on the graph to look for patterns in my results. I will also share my data with my friends to try and get an as accurate result as possible.

  2. Is exercise bad for you?

    sufficient to moderately stimulate aerobic respiration) is recommended. The type and level of exercise recommended will vary between individuals and across age groups.' It has immense results on the cardiovascular system. It reduces the amount of fat in the body including LDL cholesterol (harmful type) and triglycerides that is the free fatty acid in the blood, improves the bodies ability to uptake and deliver oxygen and this is regarded as the best measure of health, allows the heart to pump more blood with less effort helping to control systolic and diastolic blood pressure.

  3. Name the two possibilities for pelvic position when laying supine and why you would use one over the other in two different exercises

    Imprinted spine would be recommended for the Hundred since both feet are lifted off of the ground. Imprinted spine would help to maintain flexion in the spine, you could use neutral spine when the client demonstrates enough strength to maintain it during the exercise. 2. Name the 5 basic principles of alignment that are incorporated into the work and briefly describe each. Breath: The goal of the breathing is to relax unnecessary tension in the body and to encourage the engagement of the transversus abdominis on the exhale while maintaining engagement during the inhale. During exhalation the rib cage closes in and down while the spine flexes slightly, exhalation is encouraged when the spine is flexing.

  4. Investigating the effect of exercise on pulse rate

    The second thing will be standing up for 30 seconds and measuring the pulse rate after it. We will also o it two times. We will expect some difference between lying down and standing up. Afterwards we will start doing some exercise stepping up and down on a chair. We will do 20 steps and then we will measure the pulse rate. We've chosen to count the steps instead of stepping up and down for one minute because we see it will make the experiment fairer, yet, each person would do a different amount of steps in that minute.

  5. How The Intensity of Exercise affects Heart Rate

    mins Squat Thrusts 64 61 116 128 3.5 mins 4.2 mins Jumping 63 62 100 107 2.5 mins 3.0 mins This table gives a good indication of which exercise to use. Firstly the exercise the will be endured by the candidates must be something that is completed at a constant rate so both candidates will complete the exercise at the same rate and will have a used a similar amount of energy and will have exercised as intensely as each other.

  6. Investigating Pulse Rate

    I need to make sure that I run for the specified amount of time, i.e. I don't want to be running for 40 seconds and then actually I was only meant to run for 30. To make sure I don't have any time related mishaps, I will use a stopwatch o keep track of times. I also need to make sure that I say at the same pace throughout my experiment. I intend to jog during my experiment rather than hard sprinting. I need to make sure that my pulse has calmed back down to normal pace before I proceed on to the next stage, because otherwise I wont get accurate results, as if I

  7. Renal Biopsy

    If kidney function falls (say a kidney is removed to donate to a relative), the creatinine level will rise. Normal is about 1 for an average adult. Infants that have little muscle will have lower normal levels (0.2). Muscle bound weight lifters may have a higher normal creatinine. Serum creatinine only reflects renal function in a steady state. After removing a kidney, if the donor's blood is checked right away the serum creatinine will still be 1.

  8. Movements occurring at synovial joints during sports activities

    This joint allows freedom of rotation as well as back-and-forth movement in all planes. The movement will be flexibility; this is the bending of limbs at a joint. In this image we can see that Roger Federer?s ball and socket joint is in full action because we can see how his shoulders have rotated to a certain degree of angle to suit the situation he is in.

  9. Monitoring Food and Its Effects on the Body

    Each human has a different BMR, however it is lowest at rest when a person is sleeping (NHMRC 2005). It is also found to vary with age where a younger person will have a much higher BMR than adults as their body still undergoes rapid cell division, which requires abundant energy, according to Hanson (2003). However, each person performs daily activity where they are engaged in different exercise and task. When the exercise and tasks are applied, the active metabolic rate (AMR)

  10. First Aid for Sprains and Concussion

    Sprains and are a very common type of injury that affects ligaments. Ligaments are strong bands of tissue around joints that connect one bone to another. They help to keep the bones together and stable. It is very easily to recognise the symptoms of a sprain? Symptoms of sprains include: 1. Irritating Pain in the Area of Injury 2. Swelling and Inflammation 3. Loss of Movement in the Affected Body Part 4. Being Unable to Use the Joint Normally or Being Unable to Put Weight on it 5.

  11. Acute Responses to Exercise: Summary Table

    The product of Stroke Volume (SV) x heart rate (HR). The amount of blood pumped out of the left ventricle per minute Cardiovascular Increases So that more blood can be ejected out of the heart per minute and therefore more oxygen can be delivered to the working muscles Caused by a stronger ventricular contraction ? results in more blood being ejected Blood Pressure The amount of pressure exerted on the arteries when the ventricles contract (systolic) and relax (diastolic) Cardiovascular Systolic increases, diastolic stays the same Because more blood is being pumped out per beat/minute and therefore it causes an
