This week’s assignment focused on eight different responses to physical exercise. Heart
rate, stroke volume, cardiac output, systolic blood pressure, diastolic blood pressure, minute
ventilation, frequency of breathing (respiration rate), and tidal volume. In the chart listed below
are rates for a healthy man in his forties during these different levels of intensity. The following
is a summarization of what each of these subjects mean.
Heart rate is the speed at which the heart beats due to the body’s physiological needs.
Stroke volume is understood as the amount of blood that is pumped out of the left ventricle of the
heart during the heartbeat. Cardiac output is determined by the product of heart rate and stroke
volume. Systolic and diastolic blood pressure are measured at the same time but in different
ways, systolic pressure is measured by the amount of force exerted put on arteries and veins
during a heartbeat and diastolic pressure is measured by the minimal amount of force exerted on
arteries and veins between two heartbeats. Minute ventilation is a respiratory measurement also
discovered by using the product of frequency of breathing and tidal volume. Frequency of
breathing can also be understood as respiration rate, which is how often we take in a breath
during a minute of any particular activity. Finally tidal volume is how much air is taken in with
each breath.
All of these different measurements can help us in determining how people respond to
physical activity and how to improve there fitness. Without knowing what effects physical
movement affect the body we do not know how to help people or where to start. Measurements
should be taken before the start of a physical fitness plan and at the end of a program to measure
individual progress. Armed with this knowledge we can further develop safe, effective, and more
challenging fitness programs to meet different peoples goals.
