How does this compare to your hypothesis What factors account for the findings
The results are in accordance with the hypothesis since the lowest average heart rate is during at rest or upon waking up. There is a slight increase in heart rate after drinking caffeine, after eating and during surfing the internet. A significant increase in heart rate is observed after exercise. The heart rate is affected by the activity that the person is having. When there is an increase in activity, thus increase in oxygen demand also occurs inside the body, so heart rate increases.
Athletes, especially those who undergo prolonged intense endurance and strength-training, have a resting heart rate of 40-60 beats per minute. This is due to the cardiomegaly that occur which resulted to the constant exercise that they do. This is just an adaptation to the constant oxygen deficit brought about by the increased oxygen demand during exercise. At these times, the heart pumps more blood to the body to meet the oxygen demand of the skeletal muscles. As a result, in time, the heart enlarges and has a higher cardiac output per beat thus it only beats fewer times during resting state as compare to those non-athletic people.
My BMI is 21.8 which belongs to the range of normal weight of a person, thus, I have a very low chance of getting sick and die. This doesnt surprise me because I have been monitoring my weight ever since I was still a teenager due to health reasons.
Weight and height are the only factors considered in calculating the BMI of a person. Thus, it is safe to say that BMI doesnt take into consideration the distribution of mass in a person and the adiposity of a person. A lean person may be overestimated to having great adiposity than they really are, likewise, a less lean person may also be underestimated of his adiposity. Thus, an athletes BMI may be overestimated and an elderly persons BMI may be underestimated.
Adults, once their epiphyseal plate ossifies their growth arrests so whatever height they reached cant be modified. Unlike children, whose epiphyseal plates are still active, thus their height is still increasing. For this reason, the BMI of adults and children should be different. For children, their BMI are not standard because it is based on the age group they are in since the development of each age group is different from the other.
