Public Speaking Preparation Outline Specific Purpose: To inform my audience about how exercise controls weight, combats health conditions and diseases, and improves mood. Central Idea: Exercise and physical activity are a great way to feel better, gain health benefits and have fun. Introduction You’re sweating, panting, and have a feeling of euphoria. You don’t know why you feel so good when there has just been so much stress put on your body (Attention-Getter). We’ve all gone through this feeling of exhaustion known as exercise. It can tire us out, yet leave a rewarding, kind of paradoxical feeling of energy. I have this reaction every time I train for triathlons (Credibility). I’m sure you’ve had this same feeling when …show more content…
Cells depend on the oxygen and nutrients supplied by the blood to do their various jobs-from the heart muscle cells that keep your heart pumping to the brains cells that keep you thinking and coordinating your countless activities. Being active boosts high-density lipoprotein, or "good" cholesterol and decreases unhealthy triglycerides. This, in effect, protects against heart disease and stroke. Nerve cells benefit from better blood flow. Physical activity is able to shift neurons in your brain from a revved, stressed state-more vulnerable to dangerous cardiac rhythms and heart attacks-to a relaxed state. This is important because you want this system working smoothly so that it efficiently responds to changing demands for oxygen, speeding up the rate when you are active and slowing it down when you are at rest. It also improves your metabolism – the ongoing chemical processes within living cells and organisms that are necessary for the maintenance of life. For example, muscle tissue is the biggest consumer of glucose (blood sugar that has been broken down from dietary carbohydrates) and physical activities helps keep muscles utilizing blood sugar. This helps prevent insulin levels from rising dangerously in the body-a condition that leads to diabetes and damage to the nerves, blood vessels, and the liver. These all lower your risk of developing a life-threatening condition.
.It also helps to adjust the Ph of body fluids. Your body cells continually use
Subpoint- According to Dr. Joseph Marcela, “It also lowers blood pressure, clears blocked arteries, and improves our immune system” (Borreli, Lizette).
The second component is the metabolic function in the body, which can be used to control blood sugar levels. During exercise this can be tested by the ability to deal with changes in muscle and blood PH, the more active someone is leads to higher endurance to metabolites and therefore less muscle fatigue.
Thirdly, physical exercise itself could re-shape our body, make body stronger and looks healthier. It hence can improve individual’s attractiveness and confidence and hence can enable a positive life attitude. Fourthly, since the physical exercise normally would enable individual to interact with others, socialising with participants and friends in a such low-stress way might meet human’s belonging needs. It therefore could make people have a good mood and recharge themselves to fight against stress (Elizabeth, 2011).
Since 1990s, many scientists agree that exercise has positive impacts on people’s physical health and mental health (SIME WE, 1987). From Morgan and O’Connor’s research, people can reduce stress and state anxiety by doing physical activities; also gain emotional pleasure from the process (Morgan and O’Connor, 1988). Later in 1997, Landers states that physical activities can reduce people depression after weeks of regular and routine exercise. In addition, people can benefit from more
Physical activity has been proven to stimulate various brain chemicals that can leave us feeling happy and relaxed. Dr. Mary de Groot of Indiana University ran a study on the link of depression and diabetes with exercise. With the diabetes patients, she had them perform a 12-week exercise and cognitive-behavioral therapy (CBT) intervention program. The group that exercised showed improvements both in depression and in blood sugar levels. (Weir) Working out consistently can also help tremendously with our self-esteem and confidence. Exercise can boost our energy by improving our endurance and muscle strength that can benefit us in daily life situations such as at work or school. It may seem counter intuitive to say, but expending energy can help us gain more energy. It can help your cardiovascular system work more effectively by delivering oxygen and nutrients to your tissues. More than 90% of studies indicate that exercise increases energy for nearly every group, ranging from sedentary to healthy adults to cancer patients. Exercise can also make us sleep more efficiently by being able to fall asleep faster and reach an even deeper sleep. This effect happens over time the more consistent we exercise. Research has shown that exercise has a long term effect on sleep, but having quality sleep has a short term effect on our
It boosts the working and production of red blood cells in the body. Red blood cells increase the supply of oxygen in the body which is vital for muscles growth.
The Mayo Clinic Staff (Mayo Clinic, 2014) wrote, “Want to feel better, have more energy and perhaps even live longer? Look no further than exercise.” Most people have heard that regular exercise is the key to being healthy and can help prevent health conditions and diseases such as high blood pressure, heart diseases, and obesity. Type 2 Diabetes is becoming a world-wide health crisis and exercise helps lower the risk of the onset of the disease. (Whitbourne, 2012). According to many research studies, exercise benefits a lot of things including, quality of life, staying fit, boosting your energy, promotes a better sleep pattern, improves your mood, promote social relationships, and it can also put the spark back into your sex life (Mayo
Exercise also helps to create a high content of other chemicals in the brain, such as dopamine, norepinephrine, and serotonin, all which regulate the body and brain in different ways (Collins). Serotonin livens a person’s mood, while also helping to regulate sleep, develop their memory and learning abilities, and create or maintain certain social behaviors (Bouchez). Increased levels of these chemicals help people with mental illnesses respond to stressful situations in a more acceptable fashion, helping them to transition back into normal society quicker.
Physical activity has many health benefits: Helps keep your blood sugars within normal limits Helps you to feel more energetic Improves circulation Relieves stress Helps you to lose weight Increases healthy cholesterol Improves your blood pressure Improves your mood
This text, “At-A-Glance”, developed as a presentation by the CDC, describes the health benefits of exercise for each major age group. It provides examples of moderate physical activity, gives statistics about activity in the US among different groups of people, and convinces its reader of the numerous benefits of partaking in regular physical activity. According to this text, physical activity doesn’t have to be extremely vigorous to be beneficial to one’s health. This is supported by examples of moderate physical activity, such as bicycling (for 30 minutes, about 5 miles), taking walks (2 miles in 30 minutes), shoveling snow (for 15 minutes), and participating in sports such as volleyball and basketball for 45 minutes and 15 minutes, respectively. This is important for me,
3) Improves quality of life by having a positive effect on one’s energy level, self-image, and emotions.
There are a wide array of benefits aligned with physical activity and exercise. Exercising can impact a person’s mood and psychological personality as well as improve their immune system and overall wellbeing. Throughout the essay, the psychological benefits of exercise, the benefits of exercise on the human body and the recommended level of physical activity for an average sized adult will be investigated and explained. Exercise is a vital aspect of a person’s daily regime and should be included within all lifestyles.
The benefits of physical exercise in humans far outweighs the harmful effects associated with exercise. A prescription of physical activity has been known to delay the onset or prevention of many chronic diseases. An improvement in heart function, lower blood pressure and improve functional capacity is noticed after just a few weeks of exercising. Physical activity will also result in an increase of lean muscle mass, promote weight maintenance, increased flexibility, and a generally stronger more fit individual. Conversely, exercise when preformed strenuously or obsessively can counteract such positive effects, bringing up some issues like oxidative stresses, injuries, and
Exercise may be one of the most important influences on your overall health to date. While the only benefits that are mainly focused on are the physical benefits, significant psychological impacts can also be linked to exercise. Although some of these benefits aren’t viewed with much enthusiasm, studies have proven that exercise can actually improve one’s quality of life greatly by increasing not only their physical health but their mental health as well. It is because of this that exercise is a
