Exercise Not Only Enhances Physical Fitness And Performance

Introduction: In this experiment, cardiovascular fitness is being determined by measuring how long it takes for the test subjects' to return to their resting heart rate. Cardiovascular fitness is the ability to "transport and use oxygen while exercising" (Dale 2015). Cardiovascular fitness utilizes the "heart, lungs, muscles, and blood working together" while exercising (Dale 2015). It is also how well your body can last during moderate to high intensity cardio for long periods of time (Waehner 2016). The hypothesis is that people who exercise for three or more days will return to their resting heart rate much faster than people who only exercise for less than three days.

Cardiovascular and metabolic diseases are a growing problem around the world today. Not only do diseases such as diabetes and heart disease affect individuals and their lifestyles, they also affect the economy, politics, education and the professional work environment. 20-26% of individuals in the United States live with heart disease, and obesity and high blood pressure compose the greatest factors for developing this disease [20]. Studies have shown a direct correlation between the amount of sedentary time and cardiovascular and metabolic disease risk, regardless of baseline measurements [20]. Thus, increase in physical activity will decrease cardiometabolic risk factors [8]. Several studies indicate a positive correlation between physical activity and decreased cardiometabolic risk markers [2,4,11,16]. However, we now know that an individual who is getting the recommended physical activity per day can still have a large amount of sedentary time.

Insufficient physical activity is one the leading risk factors for global mortality. Physical activity not only contributes to wellbeing, it is essential for good health. Increasing physical activity levels can help prevent or manage many conditions and diseases; this includes coronary heart disease, diabetes, some cancers and obesity along with improving mental health. According to World Health Organisation (WHO), physical activity is any bodily movement by muscles that requires energy expenditure.

The study was conducted over a 16 week period and involved a control group, where participants did not exercise at all, and an experimental group, where participants followed an exercise program involving 20 minutes of aerobic exercise, 5 days per week. PEFR measurements taken at the beginning of the study were compared with those taken after. The study found that the mean PEFR of the experimental group increased by 17%, whilst that of the control group showed only a 0.4% increase. Therefore, the study concluded that undergoing aerobic exercise leads to an improvement in pulmonary function in healthy subjects. Furthermore, this indicates that in general, increasing fitness levels will increase

The effects of exercise on blood pressure, heart rate, respiration rate and electrical activity of the heart were assessed. The measurements of respiration rate, pulse rate and blood pressures were noted as described in Harris-Haller (2016). Data was first taken from subjects in a relaxed position and then followed by sets of reading after exercising based on one minute intervals. The data also noted sitting ECG traces from Harris-Haller (2016). The respiratory rate, pulse, blood pressure, P wave, QRS complex and T wave were defined for each subject. The class average was calculated for males and females and graphed to illustrate the results by gender for each cardiopulmonary factor.

Good physical health is a vital part of the well-being of every person. A major component of our physical health is “Cardiovascular fitness”. Cardiovascular fitness is the ability of the heart and lungs to provide oxygen to the muscles for activity of an extended duration. If we have a good level of cardio-vascular fitness we are able to sustain activity for a reasonable period of time and not fatigue easily. This can give individuals a variety of health benefits and allow more regular and enjoyable activity to be participated in. This research report will examine my results of cardio-vascular fitness tests and weekly physical activity events, which

Physical activity has been proven to have phenomenal benefits on the human body and is an important part of a balanced lifestyle. Statistics have shown that regular exercise can prevent illness and lower one’s likelihood of being diagnosed with a series of diseases significantly. It has been ‘medically proven’ that regular exercise can reduce a subject’s chance of being diagnosed with coronary heart disease or stroke by 35%, type two diabetes by 50%, colon cancer by 50%, breast cancer by 20%, early death by 30%, osteoarthritis by 83% and a number of other life threatening illnesses. Regular exercise can improve a person’s overall wellbeing and immunity to common illnesses. During physical activity, a person’s heart rate can increase significantly and allow more oxygenated blood to be supplied to muscles. A person’s breathing rate can increase during exercise and supply more oxygen to the lungs. The increased blood flow during exercise allows the brain to function better. Exercise has many benefits to the human body and is a major factor of disease

The literature on the effects of exercise of cardiac output maintains the idea that exercise should affect cardiac output- pulse rate, systolic blood pressure, diastolic blood pressure, QRS-pulse lag, P-T and T-P intervals, because of increased heart rate. For our experiment, we tested this theory by measuring our cardiac output before and after some rigorous exercise. We measured the individual cardiac output and then combined the data to compose a class-wide data average. We compared the results of the experiment to what we expected, which was that exercise does affect our heart. Our data from this experiment supported the notion that exercise does, in fact, change cardiac output.

Exercise is one of the most important factors in a persons’ life. Physical activity, or the lack of it, can result in a person having a healthy life or cause them to have diabetes. The benefits of exercise are countless. The positive health results, the improvement in attitude, even better academic performance are all factors which make not exercising inexcusable.

In this study, we collected the leisure time physical activity of participants, in the week prior to the study, using a validated questionnaire (21). Children reported their weekly frequency as none, 1-2 days, 3-6 days, every day of leisure time physical activity outside of school, lasting at least 30 minutes, and causing heavy sweating or large increases in breathing or heart rate. For statistical analysis, each weekly frequency received an intensity, for 0-2 days per week, mild, 3-5 days per week, moderate, and 6-7 days ( as severe ) (22).

Steady state exercise is the activity that achieves a balance between the energy required by working muscles and the rate of oxygen and delivery for aerobic ATP production. This lab is conducted to determine the heart rate in beats per minute (BPM), blood pressure (systolic and diastolic), and rating of perceived exertion response at rest to moderate cardiovascular exercise at a steady state workload and RPM. I hypothesized that exercising on an exercise bike the subjects participating in this study would have a higher rate of fatigue without fluid replacement than with fluid replacement.

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

Mammals consume oxygen and produce carbon dioxide as part of their metabolism process in order to maintain body functions. This occurs at all times, both rest and during intense work, within mammals. During times of greater work, skeletal muscles work harder than they do at rest. This in turn increases their metabolic rate and results in a greater demand for oxygen. It has been proposed that fitness training has a positive effect on both the cardiovascular and respiratory systems, which effect the maximum oxygen consumption rate during intense exercise periods. I hypothesize that individuals who aerobically exercise a minimum of at least 7 hours per week will have increased fitness, which will maximize their overall metabolic rates and give them higher VO2 max and VCO2 max values than individuals who do not have increased fitness. Ten males having different fitness levels were put on stationary bikes at increasing levels until exhaustion and VO2-max and VCO2-max was then measured from each individual. It was found that there was a slight upward trend between fitness-VO2max and fitness-VCO2max, although this trend was not statistically significant when represented by the T-test values through statistical analysis. Further experiments should be done in the future to verify a statistically significant correlation.

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
