Hemoglobin, which is a mechanism that transports iron, binds to oxygen to carry it through your bloodstream. The ability of each molecule of hemoglobin to bind to oxygen remains limited. The percentage of that capability -- called oxygen...
Everyone admires the professional basketball player that can leap high in the air to make the perfect dunk. Leaping vertically is an essential skill especially for B-ball players. While there is a natural component to being able to jump high,...
In the course of an average lifespan, the heart beats about 2.5 billion times, tirelessly pumping oxygenated blood through the vascular system to all the tissues of the body. Regular exercise temporarily makes the heart work harder; but like other...
Exercise increases heart rate, which may be closely monitored under certain training regimens. Breathing also increases and the skin produces sweat. In fact, breathing and sweat production are processes that respond to and benefit from an...
When dieters decide to embark on a fat loss regimen, exercise is one of the first activities to pursue. But it is hard to know which type of exercise promotes fat loss more than others. There is not a single type of workout that is better than...
The benefits of exercise go beyond those that you are able to see. Your heart and lungs become more efficient over an extended time period participating in exercise. Not all types of exercise improve your cardiovascular functions. Cardiovascular...
You can increase your metabolism by exercising on a regular basis. Metabolism is the process your body uses to convert food into calories, which you then use for fuel. Your metabolic rate is the number of calories your body burns in an average...
The metabolism converts the food we eat into usable energy. When we eat, the digestion process breaks down all foods into their component parts, and the carbohydrates are converted into glucose. Insulin puts the glucose into the cells where the...
Adrenaline is a neurohormone that increases metabolic rate, alertness and the ability for muscles to contract, making it a valuable hormone to increase for athletes and office workers alike. A single exercise session can acutely increase...
All exercise increases your heart rate. It is a basic physiological function that, as you exercise, your heart rate will increase to provide adequate oxygen and blood circulation to your body. However, understanding the specifics of how your heart...
All exercises and activities burn some amount of fat and increase your fat-burning potential, whether they are aerobic or anaerobic, according to exercise physiologist William McArdle, author of "Exercise Physiology." The best way to increase the...
Every type of exercise increases your heart rate to some extent. The moment you begin to engage in aerobic or anaerobic activity, your heart begins to work harder to effectively pump the blood and oxygen your body needs to perform the activity....
It has been well established that exercise is good for your self-esteem, especially when associated with rewards, such as feelings of accomplishment and social acceptance. However, in order to determine the underlying causes of these positive...
The term "range of motion" refers to the distance at which your joints allow flexion, extension and rotation in various planes of movement. Range of motion exercises enhance athletic performance and facilitate pain-free movement during daily...
When you exercise intensely, you may experience a euphoric feeling due to an increase in the production of neurotransmitters. There are several neurotransmitters that influence mood, including serotonin, adrenaline and dopamine. Exercise may have...
Exercise increases venous return by forcing your body to add and enlarge blood vessels. In addition to circulatory improvements, exercise helps muscles and tissues become conditioned to allow them to overcome the stresses of working out. During...
Exercise increases heart rate, but the degree of increase depends on the duration and intensity of the exercise. The heart rate increases because the demand for oxygenated blood in your muscles and organs increases as the level of physical...
Exercise has a number of benefits, but one that you might not often consider is its ability to improve your skin. Regular exercise stimulates collagen production and increases the amount of human growth hormone released by your body. Both of these...
At room temperature, nitric oxide is a toxic gas, so it might seem surprising that this poisonous compound could play any part in normal human physiology. Remarkably enough, however, your body actually uses nitric oxide in several different...
Cardiovascular or aerobic exercise increases the heart rate, which delivers oxygenated blood to the lunges and muscles. Cardio provides several health benefits like increased stamina, improved immune system function, a stronger heart and fat loss,...
The sacroiliac joint, or SI joint, connects your sacrum to the pelvis to provide stability in both parts. Although this joint has limited mobility, its function is to allow some twisting motion of the sacrum and hip joints when you move your legs....
The SI joint, or sacroiliac joint, connects your sacrum to ilium of your pelvis. Its functions are to stabilize your spine and pelvis and to absorb shock when you move. Although there is limited movement of the SI joint, there should be some...
Your heart rate is a measure of how hard your heart works to pump blood through your body. In fitness terms, your heart rate is also a measure of how many calories you burn during your exercise session. To understand how exercise increases your...
IQ stands for intelligence quotient, and IQ tests aim to measure a person's intelligence. It consists of different areas including but not limited to reasoning, induction, spatial visualization and verbal comprehension. Its earliest uses were...
The human skeletal system is composed of several important vitamins and minerals that help to keep it strong and rigid. According to John JB Anderson in the American "Journal of Clinical Nutrition," calcium is the most concentrated mineral found...
The rate at which your body burns or uses oxygen and fuels is called metabolism. Metabolism is a necessary part of the life and of the strength and endurance of muscles and organ and tissues in the body. Stronger, larger muscles are able to...
Common acne triggers include sweat, humidity and friction from snug-fitting clothes. For many people, exercise leads to exposure to some or all of those triggers, and in these cases, exercise can increase acne. Fortunately, all of these triggers...
Your thyroid gland, located in your throat, is an important regulator of metabolism that affects how your body responds to exercise. Exercise acutely raises thyroid hormone levels. While the longer term effects of exercise training are less clear,...
High blood pressure, or hypertension, affects about 74.5 million Americans, according to the American Heart Association. As much as one-third of all cases go undetected. The Centers for Disease Control estimate the cost of hypertension in this...
