and heart rate after exercise? After exercise the R-R interval increased steadily from 0.48 to 0.68 seconds‚ while the heart rate BPM decreased steadily from 123 to 76; both trending back towards the resting values. What happened to the T-P interval during exercise? Outline what this means for ventricular filling time. During exercise there was a significant drop in the T-P interval which then steadily increased when exercise was completed. The T-P interval represents a period between ventricular

Change in respiratory rate during exercise Aim: To record and investigate how the breathing rate varies for the duration of light and heavy exercise. Introduction: When an individual exercises‚ the muscles being used needs extra energy from oxygen. The lungs pump oxygen to the heart‚ and then the heart pumps the oxygenated blood through the blood to the particular muscle that is working. The human body has a series of organs working together‚ which is named the respiration system. The organs involved

reported the findings of a study on teen suicide rates in Alaska. Using death certificates and U.S. census data to record trends in suicide rates among Alaskan teens ages 14-19‚ it was found that the teen suicide rate was 31.5 per 100‚000 persons each year. The study tested three hypotheses‚ the first being that the overall suicide rate of Alaska teens ages 14-19 during 1979-1993 would vary according to residence‚ gender‚ race‚ and age. Indeed‚ “suicide rates varied up to sixfold by race‚ gender‚ and local

on cardiovascular functions such as pulse rate‚ pulse lag‚ the PT interval‚ the TP interval‚ systolic‚ and diastolic blood pressure is noticeable after running down the steps of Long Hall and back up to the third floor. As Table 1 shows‚ the data support the initial hypothesis that the pulse rate will increase‚ the pulse lag will decrease‚ both the PT and TP intervals will decrease‚ and the systolic and diastolic blood pressure will increase. The pulse rate mean before exercise was about 78 beats per

The Population Growth Rate in India For many years concern has been voiced over the seemingly unchecked rate of population growth in India‚ but the most recent indications are that some success is being achieved in slowing the rate of population growth. The progress which has been achieved to date is still only of a modest nature and should not serve as premature cause for complacency. Moreover‚ a slowing of the rate of population growth is not incompatible with a dangerous population increase
