On the other end of the spectrum is anaerobic exercise, an excellent way to stay in shape, increase muscle mass, or mold muscle you already have. It is commonly referred to as strength training. According to the article, “Is Weight Lifting Safe for Kids”,
“strength training-also called weight training and resistance training and distinct from weight lifting, power lifting, and bodybuilding-involves a variety of methods including use of free weights (dumbbells and barbells) and weight machines”. (“Is weight lifting safe for kids?") These anaerobic exercises involve a low heart rate and high pressure on the muscles, causing microscopic tearing of the muscle to stimulate rebuilding of larger and stronger muscles. “Resistance-training activities,

Anaerobic exercise is often viewed as exercise for younger people, as “children and adolescents lift weights to increase their strength or enlarge their muscles.” (“Strength training, weight and power lifting, and body building by children”). However, anaerobic exercise is also beneficial for older people. “Especially for people in their late 70s and
80s, strength training shouldn't be neglected”. (Manson) One example of resistance training is the bench press. This exercise increases pectoral muscle strength and allows the body to lift heavier weights, as well as look more defined. Another example of an anaerobic exercise is a squat exercise. Keeping the heart rate low and pressing large amounts of weight allows extreme muscle gain upon the legs and powerful shaping to the body.
The anaerobic workout style exposes the body to intense weight on all joints and bones and has some serious potential threats, if done incorrectly. For instance, when squatting it is important to watch how the bar is set on your back otherwise, it could fall, damaging anything below. When deadlifting, it is important to keep a straight

One of the most effective anaerobic exercises for fat burning would be sprinting.
“Sprint training increases stride power and running economy, benefits that transfer all the way down to marathon speed and below”. (“Workout Of The Week”) Sprints are short bursts, less than 2 minutes, of high intensity running. After two minutes the body uses the lungs to push oxygen into the bloodstream causing the body’s aerobic system to kick in. Sprinting activates your entire body, elevates your heart rate, puts pressure on your lungs, and forces your body to burn calories to help maintain the high intensity.
Although the positives are extremely desirable, we must be careful how the training is maintained. Without proper equipment and rest, our body will break down in time. For example, when sprinting, “you will need shoes with good soles for traction” to protect the ankles, knees, and other joints. (Shortliffe) With the quick bursts of running and turning from sprints, intense pressure is placed on these areas causing impact pain or loss of flexibility and large amounts of discomfort, and even possible arthritis.
•While exercising your lungs tries to increase the intake of oxygen as well as release the carbon dioxide.
The circulatory system and respiratory system share a highly important relationship that is crucial to maintaining the life of an organism. In order for bodily processes to be performed, energy to be created, and homeostasis to be maintained, the exchange of oxygen from the external environment to the intracellular environment is performed by the relationship of these two systems. Starting at the heart, deoxygenated/carbon-dioxide (CO2)-rich blood is moved in through the superior and inferior vena cava into the right atrium, then into the right ventricle when the heart is relaxed. As the heart contracts, the deoxygenated blood is pumped through the pulmonary arteries to capillaries in the lungs. As the organism breathes and intakes oxygenated air, oxygen is exchanged with CO2 in the blood at the capillaries. As the organism breathes out, it expels the CO2 into the external environment. For the blood in the capillaries, it is then moved into pulmonary veins and make
This lab experiment was conducted in a Texas Woman’s University exercise physiology lab room, on September 20, 2013. It consisted of two main participants: A trained participant (Male; 30 years old; 72 in. tall; 82.9 kg) and an untrained participant (Female; 20 years old; 65 in. tall; 75 kg). They were selected by my Prof. April Hartman to participate because they were best qualified to conduct the study in our class. Both participants were assigned to carry out the same experimental task. The Bruce Protocol (graded test) on a treadmill (mode of exercise) was used to conduct the VO2max test. The materials needed were: 1 metabolic cart (with computers); 2 mouthpieces; 1 nose clip; 1 treadmill; 1 RPE scale; 1 timer; pen; paper; and a HR monitor.

Exercise is an easy and attainable way to lose weight. A study in Durham, North Carolina showed this. Overweight men and women aging from 40-65 were split into three groups. Group 1 had to do the equivalent of 20 miles of jogging per week at 65%-80% peak oxygen consumption. Group 2 had to do the equivalent of 12 miles of jogging per week at 65%-80% peak oxygen consumption. Group 3 had to do the equivalent of 12 miles of jogging per week at 40%-55% peak oxygen consumption. Of 302 subjects screened, 182 met criteria and were randomized and 120 completed the study. There was a significant (P<.05) dose-response relationship between amount of exercise and amount of weight loss and fat mass loss. The high-amount/vigorous-intensity group lost significantly more body mass (in mean [SD] kilograms) and fat mass (in mean [SD] kilograms) (-2.9 [2.8] and -4.8 [3.0], respectively) than the low-amount/moderate-intensity group (-0.9 [1.8] and -2.0 [2.6], respectively), the low-amount/vigorous-intensity group (-0.6 [2.0] and -2.5 [3.4], respectively), and the controls (+1.0 [2.1] and +0.4 [3.0], respectively). Both low-amount groups had significantly greater improvements than controls but were not different from each other. Compared with controls, all exercise groups significantly decreased abdominal, minimal waist, and hip circumference measurements (http://www.ncbi.nlm.nih.gov/pubmed/14718319).
Not only does interval training increase the amount of oxygen the body can consume during exercise, but its efficiency in delivering the oxygen to the key muscles. This is attributed by researchers to increase in stroke volume. Stroke volume is the volume of blood pumped from one ventricle of the heart in a single beat. The body can only continue performing exercise when the performing muscles receive oxygenated blood. Therefore, it is crucial that the oxygenated blood supply continue to be open throughout exercise. Stroke volume can increase through a higher left ventricular contractile force and/or through an increase in cardiac filling pressure, which raises end-diastolic volume and resultant stroke volume (Laursen, 2002). In addition to increased stroke volume, researchers have identified increased activity b...
Whether you are lifting weights or going on a run your body will constantly maintain its homeostasis. When you exercise you create diverse effects on the systems in your body, while they are trying to create more energy to keep exercising and to help you recover after. (1) When you create this energy from exercise the effects on your homeostasis is an increase in your breathing and heart rate, and an increase in sweat production.

During the first one or two minutes of exercise, before the heart has pumped enough oxygenated blood to the working muscles, the muscles are powered by anaerobic energy. In order for these muscles to continue exercise, the body must supply them with continuous supply of oxygen, the more efficiently this is done, the better the cardiovascular fitness level. During cardiovascular conditioning, a program such as interva...
The respiratory system is a complex organ structure of the human body anatomy, and the primary purpose of this system is to supply the blood with oxygen in order for the blood vessels to carry the precious gaseous element to all parts of the body to accomplish cell respiration. The respiratory system completes this important function of breathing throughout inspiration. In the breathing process inhaling oxygen is essential for cells to metabolize nutrients and carry out some other tasks, but it must occur simultaneously with exhaling when the carbon dioxide is excreted, this exchange of gases is the respiratory system's means of getting oxygen to the blood (McGowan, Jefferies & Turley, 2004).

The roles of the circulatory and respiratory system both carry important responsibilities and are essential in their jobs to the human body. The circulatory system is one, if not the, most important system in the human body. The circulatory system is made up of the heart, blood, and blood vessels. Within the blood vessels, there are three types: arteries, veins, and capillaries. The heart is an organ made up of cardiac muscle that has a role similar to a pump. When the muscles in the heart contract, it pumps fresh blood away from the heart, through a main artery called the aorta, and to the organs and cells of the body. Nutrients and oxygen then enter the cells through diffusion of the tissues. The respiratory system transports oxygen to the circulatory system. When transporting oxygen to the circulatory system, this will in turn transport oxygen to the rest of the cells in the body. Aside from transporting oxygen to the body, the respiratory system also plays a role in the removal of carbon dioxide and other contaminants in the body. These two systems effectively and efficiently work together in order to supply the body with oxygen and remove carbon dioxide and any other
