Final Hypothesis of Exercise and Weight - Essay Example

Past studies indicates that when one is engaged in regular physical exercise then the weight is likely to be moderate. This is because of the increased metabolic reaction that improves the respiratory processes in the body and makes a lower weight individual to gain gradually to some limit and burn excess fats in a person with much weight to slim down to some moderate weight. This simply means that exercise and ideal weight are directly positively correlated. The choice of Exercise as the independent variable and weight as the dependent variable is based on the relative influence they have on each other regarding the physical health status in an individual through the weight measure of a person (Gedatus, 2001).

These two variables have been realized to be the most appropriate towards the risk of obesity and other weight related disorders. The main assumptions regarding the relation ship between these two variables are explained below. There is a steady response of state of the heartbeat rate with changes in exercise workload. It is also worth to note that it is assumed that there is a linear relationship between rate of respiration, heartbeat rate and exercise workload. . People who undertake less physical activities may undergo less respiratory processes whereas people who undertake more physical work undergo more respiratory processes.

In other words, people who undertake less physical activities may gain more weight than others. In short, exercise workload, respiratory processes and obesity have direct links between each other. Obese people are at increased risk of respiratory symptoms, such as breathlessness, particularly during exercise, even if they have no obvious respiratory illness Obesity has a clear potential to have a direct effect on respiratory well-being, since it increases oxygen consumption and carbon dioxide production, while at the same time it stiffens the respiratory system and increases the mechanical work needed for breathing (Salome et al., 2009) Heartbeat rate depends not only to exercise workload but also to the age of the exerciser.

In other words, heartbeat rates of a younger man during exercise will be more than the heartbeat rates of an older man who is experiencing the same exercise workload (See appendix 2 for more details). Moreover, heartbeat rate calculation formula for women and men are different. The maximum heartbeat rate of a woman can be calculated using the formula 226-age whereas that of a man will be 220-age (Heart Rate Chart, 2009). It is evident from the above formulas that heartbeat rates of women will be more than that of men during exercising.

Measurement of heartbeat rates, before, after and during physical exercise will give a proper idea about the fitness level of a person. For normal persons, heartbeat rates return to normal state quickly after the exercise workload whereas for others it may not come back to the normal state quickly. Linear relationship between
