Human Responses to Sports & Exercise
Assessment Task 1 Workbook

Student Name: Daniel Kelly

Instructions:
Read the information provided, and answer the questions. Please note that your answers should be concise, to the point, and include brief explanation.

Part A:

Scenario: You are a fitness coach and are instructing a personal fitness training session for an athlete in a gym. The session involves cardiovascular and resistance training.

Questions:

1. You noticed that heart rate increased immediately before exercise (above resting levels). Why is this the case?
Heart rate may increase before the start of any exercise; this is due to an involuntary

Questions:

1. In terms of muscle fibres, what long-term changes might occur due to the treadmill exercise?
After 20 weeks of training, as treadmill exercises are generally aerobic and endurance related. During aerobic exercise the muscle is extracting oxygen from the blood supply to feed the muscles with sufficient energy, over a 20 week period the capacity of capillaries may have adapted and increased so that the capacity for oxygen exchange between tissue and capillaries can be improved and this would lead to a better control of metabolism in muscle fibres. Due to the change in the muscle fibres more oxygen is being provided and this leads to a better physical performance.

2. The athlete took a blood test at 0 weeks and 20 weeks of training and found an increase in erythropoietin at 20 weeks? Explain how this might benefit his performance?
Hormones/ the amount of red blood cells produced for muscles more oxygen higher stroke volume.

3. The athlete is now better at performing a single-leg squat that he was 20 weeks ago, claiming his balance is better. What adaptations have contributed towards this

    I predict also a higher rep count during stage 1 (aerobic exercise) as a pose to during stage 2 (anaerobic exercise). Cellular respiration is the process of energy production and consumption within the body and during cellular respiration there are many bonds being broken of sugars and ATP. I felt warmer after lifting the dumbbell because whenever a bond is broken, energy is released in the form of heat as a by-product to normal energy. Oxygen is a vital part to cellular respiration and oxidative phosphorylation because without it there would be no hydrogen ions being pumped across to form ATP. In aerobic respiration, approximately 30 ATP’s are created whereas in anaerobic only 2 are created because of the lack of oxygen.…

    Introduction: A cardiac output, also know as minute volume is the volume of blood ejected from the left or right ventricle of the heart in one minute. It’s the primary determinant of oxygen transport within the heart and entire body. Sufficient blood flow is highly important especially during exercise because the body will need much more oxygen. With the need for more oxygen, the heart will begin to beat and pump faster during exercise. As the heart rate increases so will the blood flow, also known as hyperemia.…

    This type of respiration causes the level of oxygen in the blood to drop and carbon dioxide levels to rise. When sensors in the body detect the change, brain sends the signals to the intercostal muscles and diaphragm to contract more often to increase the breathing rate, thus increase the amount of oxygen supplied to the lungs and from there to the blood that transports it to muscles. During the exercise the heart rate and the stroke volume are increased, so heart could pump more blood faster to supply muscles with the oxygen from the blood. Over time, if the exercise is done consistently, heart muscles get stronger and walls of arteries get thicker and more used to the higher pressure, which reduces the risk of heart diseases.…

    About 15%-20% of cardiac output goes to the skeletal muscles at rest. Cardiac output is equal to heart rate times stroke volume. Increasing or affecting either heart rate or stroke volume will affect the cardiac output. During exercise, the cardiac output normally will be increased three or four times compared to resting state due the increased heart rate and stroke volume. During exercise, the skeletal muscles will need more oxygen when muscle contraction, and it would activate the sympathetic nervous system to cause the heart to beat faster and also increase the stroke volume so that the maximum blood and oxygen could be delivered to the contracting muscles.…

    The uptake of oxygen into muscles is what facilitates muscle contraction. Oxygen that is obtained through breathing by the lungs is transported to the rest of the body, as well as the heart by means of haemoglobin. The rate of liberation of oxygen from haemoglobin has an effect on the quantity of oxygen available in the muscles for a muscle contraction to ensue. The higher the oxygen concentration in the muscle the greater the force of muscle contraction. Temperature has an effect on the muscle’s contractile ability.…

    “Acute Exercise Improves Motor Memory: Exploring Potential Biomarkers” is a study published in Neurobiology of Learning & Memory that focuses on the potential role several biomarkers have on exercise induced improvements of human motor skill acquisition and retention (Skriver et al., 2014). This correlational study expands on an earlier study conducted by Roig, Skriver, Lundbye-Jensen, Kiens, & Nielsen which found that a single cardiovascular exercise session improved motor skill learning by optimizing long-term motor memory (as cited in Skriver et al., 2014). Biomarkers examined included vascular endothelial growth factor (VEGF), insulin-like growth factor (IGF-1), brain-derived neurotrophic factor (BDNF), dopamine, epinephrine, norepinephrine, and lactate. The main finding of the study was that motor skill acquisition and retention improved by acute cardiovascular exercise are associated with increased levels of biomarkers that play a role in memory and learning processes.…

    During phase II, central command helps maintain stimulation along with feedback from exercising muscle tissue (Eldridge, F. L. (1994). Lastly, phase III occurs once all of the aforementioned modulating factors reach steady state (Eldridge, F. L. (1994). As an exercising individual moves from steady state or submaximal exercise towards maximal effort, ventilatory variables further fluctuate as a result of loss of homeostasis and inability to maintain oxygen supply to exercising muscle. Progressive increases in exercise intensity and their subsequent increases in minute ventilation are portrayed in Figure 2. The first increase in VE is identified as ventilatory threshold 1 (VT1) results from rising CO2 levels; whereas, ventilatory threshold 2 (VT2) is the result of the linear breakaway of ventilation during high intensity exercise and its accumulating byproducts (Lucía, Hoyos, Pérez &…

    Cardiovascular Response

    • 384 Words
    • 2 Pages

    Cardiovascular Response: When exercising the muscles requires a constant supply of oxygen, it is the hearts job to make sure there is enough oxygen being pumped round the body for the muscles, the heart has to pump harder and faster as more oxygen is required to get round the body to the muscles in use otherwise they will fatigue quicker. If this is repeated regularly, then over time the heart will become stronger as will become more used to the higher demands. At the start of exercise, the nerves in the brain detect cardiovascular activity. The nerves then send out chemical signals to increase the heart rate, as well as the strength at which the heart is pumping. This means that more red blood cells are pumped around the body which carries…

    What can temporarily affect the acceleration of your heart? - stress - excitement - caffeine Things such as meditating or taking deep breaths may help to slow down your heart rate. Exercising will increase your heart rate and it will stay elevated for the amount of time exercise is continued. At the beginning of exercise, your body will remove the parasympathetic stimulation, which enables the heart rate to gradually increase. As your exercise gets more strenuous, the sympathetic system ‘kick in’ to accelerate your heart rate even more.…

    Thus , the oxygen requirement to the respiratory muscles increases which results in decrease in use of oxygen by locomotor muscles. Resulting to this lack of oxygen, respiratoy muscles become fatigue. Morever, post exercise oxygen consumption and energy expenditure is more after high intensity exercise (Doucet, Imbeault, Alméras & Tremblay, 1999) The purpose of conducting a lab is to measure the metabolic and energy expenditure with cycle ergometry. For any activities taking longer time than few minutes, main source of energy is through aerobic metabolism, as we do not store more amount of o2 in body, we must deliver o2 to tissue when it is needed during prolonged exercise.…
