Skipping Affecting Heart Rate

The lungs have a huge blood supply and a huge surface area so they are very effective at getting oxygen out of the air. They are also in charge of getting rid of the carbon dioxide excess and some of the excess water as water vapour. It is the lungs job to get the oxygen and the heart has to pump it around the rest of the body. Energy metabolism; when people are exercising their muscles are contracting and they are using more energy so they will need more oxygen getting to the muscles and my heart

If the resistance increases, cardiac output decreases and the blood pressure increase and if the resistance decreases, cardiac output increase and the blood pressure decreases. During each contraction, the amount of blood pumped out by one ventricle is stroke volume. The number of heartbeat in each minute is known as heart rate. The normal heart rate value for adult is 60-100 beats per minute. The cardiac output is directly proportional to the stroke volume and heart rate. The average arterial pressure during one cardiac cycle is mean arterial pressure (MAP), which is directly related to the cardiac output and resistance. The instrument sphygmomanometer with an air cuff attached to the reservoir is used to detect blood pressure associated with the pulse.

Exercise increases the use of energy by your muscles, which activates a series of reactions to create new energy to keep exercising and maintain homeostasis. The first reaction that occurs is an increase in your breathing rate. Energy creation requires significant oxygen. The only way to provide the necessary oxygen is to increase the speed at which your respiratory system is introducing it into your bloodstream. The harder you exercise, the more energy is used, resulting in your body increasing your breathing rate even more to maintain adequate energy levels for balance.

Homeostatic is all about balance so when you begin to exercise, you need more oxygen. The harder you breathe the more energy it takes to replace it. Your body temperature while exercising also increases; typically it creates too much heat so your body has to figure out a way to release the heat so it doesn't become dangerous. This is done by sweating

Introduction: Heart rate is the measure of beats the heart pumps per minute. A resting heart rate for a normal healthy individual is between 60-100. If the resting heart rate is above 100 it could be a result of Tachycardia and if it is below 60 it could be a result of Bradycardia. Heart rate can fluctuate due to over all health, whether you active or sedentary, or through certain substances we put in our bodies.

A normal resting heart rate for a teenage girl is between 60 and 90 beats per minute. The human heart is believed to beat faster after one eats a large meal or even a small meal. However, the larger the meal the faster the heart will beat and the type of food (sour, salty, sugary...) also has an effect on the heart beat. Heart palpitations are when the heart beats irregularly; normally this is not serious and will be caused by exercise, stress, eating processed food, drinking some form of stimulant and many more. It can also be a symptom of arrhythmia; however the subjects that will be chose to be tested will not be diagnosed with this condition. The quantity of food eaten will also effect the person for example, having 2 tablespoons of sugar will affect the subject more than if the person ate 1 teaspoon of sugar.

We’ve all gone through this feeling of exhaustion known as exercise. It can tire us out, yet leave a rewarding, kind of paradoxical feeling of energy.

Conclusion & Evaluation: Conclusion: As depicted in my Hypothesis, Oxygen consumption rises, such as the heart rate when the body starts exercising. Through the 1.5 mile run I could prove that Oxygen consumption and Heart Rate depend on each other. The cardiovascular and respiratory system cannot function without the other. The heart working together allows metabolism to occur in all parts and systems throughout the body. This is done as the lungs deliver oxygen and also removes wastes.

The rhythmic contractions of heart (produces lub-dub sounds) supply the blood to all the body parts. In a healthy adult, the normal heart rate is 72 beats per minute and this may increase or decreases depend upon the physiological changes.

As with most forms of training, aerobic and anaerobic training are similar in the fact that both increase in size and number the amount of mitochondria, myoglobin, and capillarization, by way of muscle hypertrophy. In addition, both forms require the body to adapt and increase recovery abilities in order to optimize training results. From the respiratory system’s use or non-use of oxygen in delivering energy, to the digestive system’s ability to process more nutrients, to the endocrine system's ability to regulate hormonal output for more efficient energy usage and tissue growth, both training methods are vital to the body’s growth and development. Both benefit from muscle glycogen to fuel their

Heart rate variability (HRV) is quickly becoming a “buzz word” in fitness, but in reality this is a very old technology. Dating back to at least 1948 (15) HRV has been a commonly used method in research and is an accepted diagnostic tool in several diseases/conditions, such as post-traumatic stress disorder and type 2 diabetes (9, 23).

A normal heart beats 60 to 100 beats per minute. However, those who suffer from arrhythmia (also known as dysrhythmia) have an irregular or abnormal heartbeat; either too fast or too slow. It is important to diagnose arrhythmia early because when the heart beats irregularly, the blood is not being pumped properly which could lead to heart defects and improper blood flow throughout the body. People who are diagnosed with this disorder are at risk of future heart disease. Arrhythmia is not contagious but some heart rhythm disorders are often inherited, so if one person is diagnosed with an arrhythmia, other family members may be affected too.

“When you exercise for a longer duration, you're going to use the slow twitch fibers that are really good at burning fat. If you went and did a couple hundred meter sprints for your workout, it only works the fast muscle fibers, and they use primarily carbohydrates and don't burn that much fat at all.

You are much more likely to burn actual fat after your weight training workout. This is because the body’s first fuel source (glycogen) has been almost completely depleted when you’re weight training. With glycogen depleted, the body is much more likely to use fat as a fuel
