"Transport Pulse Rate Practical" is an engrossing example of a paper on fitness and exercise. Analysis Before jogging, the resting pulse rate was 73bpm (beats per minute). This is because the body required little energy due to limited activities. Carbohydrates and fat are the key sources for energy which are later converted through the citric acid cycle into energy. Adenosine triphosphate (ATP) is the one responsible for transporting chemical energy (Thiriet, 2014). During the exercise After the first five minutes of the exercise, the pulse rate rose to 76bpm. The rise was recorded due to an increase in oxygen supply within the body while eliminating excess carbon dioxide.
According to Thiriet (2014), the carbon dioxide (CO2) and oxygen (O2) are transported by the blood’ s hemoglobin from and to the lungs. It is at this point where the gases are exchanged through the process of diffusion. After 10 minutes, the pulse rate increased to 87bpm due to the production of more energy. During the exercise, the muscles produced lactic acid as a byproduct which decreased the blood pH that promoted adrenaline release. The adrenaline increased heart pumping which led to the increase of the heart rate to 87bpm.
The increased heart rate is caused by more pumping of oxygenated blood into the muscles for the production of energy. While jogging, breathing necessitates the intake of new oxygenated air through the lungs by inhalation, while getting rid of the used air containing carbon dioxide by exhalation (Thiriet, 2014). Based on Thiriet (2014) the heart relaxes and contracts due to the sino-atrial node signals into the system. During jogging, the heart is stimulated by the signaling process to beat faster due to stimuli from many body parts.
The exercise demanded more energy into the muscles due to an increase in glucose levels. Jogging is a strenuous exercise, requires aerobic metabolism due to the use of oxygen. Since oxygen is transported by the blood, pumps quickly for the maintenance of oxygen supply in the muscles. The pulse rate could be felt at the neck, wrist and upper arm due to the presence of the blood vessels near the surface (Thiriet, 2014). Due to the rapid heart rate, it also increases the breathing rate.
The movement is maintained at a ratio of 1 breath per every 4 heartbeats. The breathing rate increased due to an increase in energy and oxygen demand. Mooi (2009) explains the process was necessitated by the breakdown of glucose in order to meet the deficit needs. 6 oxygen molecules combined with 1 glucose molecule in order to produce a usable energy source, ATP. The process further necessitated the production of carbon dioxide molecules. The breathing rate also increased so as to enhance carbon dioxide removal and increase oxygen. The increase in oxygen level inside the lungs was assisted by hemoglobin which helped in its transportation to the muscle cells. After the last 15 minutes of jogging, the pulse rate shot to 90bpm which was an increase of 3bpm from its initial 87bpm.
This was as a result of more carbon dioxide and fats being broken down into energy. The blood pumped per minute by the blood is 70 mls. During the vigorous exercise, the heart rate doubles. Therefore, the cardiac output at this point was 6300 mls/min (90*70=6300mls/min).
This led to the excretion of more waste products like water, heat and carbon dioxide through the process. The excretion was supported by ATP which necessitated the storage of more energy used by the cell (Mooi, 2009). Glucose and oxygen intake increased at this stage causing an increase in energy production. Glucose was absorbed into the bloodstream by the digestive system. The oxygen diffused into the lungs through the alveoli which were later diffused into the bloodstream. Ox haemoglobin was achieved through the absorption of oxygen by the haemoglobin. At the 15 minutes period, the vigorous actions necessitate the production of more energy than usual.
The breathing rate level further increased due to the ribs muscles moving out and up. The diaphragm contracted leading to a decrease in pressure. The diaphragm and intercostal muscles contract more leading to deeper breaths. The heart rate increased due to the rapid contraction of the heart muscles which led to an increase in blood pressure. Based on Shaw (2005) the pressure promoted the transportation of glucose and oxygen quicker. It further assisted in plenty of circulation of blood to the lungs capillaries for more oxygen absorption.
The correlation between heart rate and heart rate cannot be separated. At the 15 minute duration, the enzymes denatured due to high body temperatures. The denaturing caused decrease metabolic rates. Therefore, the muscles, enzymes and body cells required an increase in energy due to vigorous activities and respiration process. Therefore, this also led to an increase in breathing rate due to blood oxygenation and carbon dioxide removal. During the respiration, sugar and other energy-producing substances that constitute the food digestion process, are broken down in oxygen presence, energy, carbon dioxide, and water.
Shaw (2005) adds oxygen and sugar combine to form carbon dioxide and water which leads to the emission of chemical energy. Due to the vigorous exercise; the pulse rate, blood pressure and breathing rate also increased too. After the stop of the exercise, it led to a drop in the heart rate from 90bpm to 87bpm. This was a difference of 3bpm. 15 minutes after the stop of the exercise, I recorded the pulse rate at 83bpm and thirty minutes after, I recorded 80bpm.
1 hour after the exercise, the heart rate returned to 73bpm. The irregular decline range was due to my irregular exercising pattern. For regular aerobic athletes, their heart is usually enlarged due to increased blood pumping which every contraction. The heart rate reduction usually occurs with frequent exercises. This is evidence of a relatively unfit status. The long recovery duration was caused by oxygen debt which needed to be replaced by rapid blood pumping (Shaw, 2005). The low recovery rate could also have been contributed by my frequent caffeine intake from stimulant drinks.
Regular recovery time could also be achieved by irregular exercisers due to moderate or light exercise undertaking. Healthy diets could also assist in achieving quick recovery rates among healthy individuals.
