Exercise Science Basics

The amount of sleep and athlete gets appears to have a large impact on sports performance.

The notion of a surge in endorphin levels resulting in a "runner's high" has been talked about for decades, but only in 2008 did the myth become fact.

Exercise may improve your immunity, but too much may make you sick. Have you gotten sick after intense endurance exercise?

In 2008 did researchers found evidence showing that exercise causes endorphins to be released in the brain. They believe it's this flood of endorphins that results in mood changes, such as euphoria and the famed "runner's high." But not all athlete's experience this sense of well-being. Have you? Share your story.

Energy balance is a complicated process that is made up of many factors. Whether we gain, lose or maintain body weight is largely depended upon our metabolism, the amount of exercise we do and the number of calories we consume. So what exactly is metabolism and how does it affect my body weight?

Learn the difference between acute and chronic pain.

Moderate exercise may boost the immune system function, but intense exercise can have the the opposite effect.

Is there a best time to exercise? Many athletes debate the pros and cons of morning, afternoon or evening exercise and athletic performance. But what does the research say? The simple answer is that the "best" time to exercise might be the time that is most convenient for you.

Endurance training in sport refers to an athlete’s ability to sustain prolonged exercise for minutes to hours. Endurance training improves the circulatory and respiratory system's ability to supply energy to the working muscles in order to support sustained physical activity.

Deconditioning, or losing fitness, when you stop training is unavoidable. However, how quickly you lose fitness depends on several factors, including how fit you are, how long you have been exercising, and on how long you stop.

Fast and slow twitch muscle fibers (or Type I and Type II fiber types). Does muscle fiber type determine an athlete's strength, power, speed and endurance or athletes respond to training?

Athletes and mitral valve prolapse - any cause for concern?

Learn why your muscles fatigue during high intensity exercise and why you can go longer at a slower pace.

It is estimated that four to seven percent of the population lives with mitral valve prolapse. Most live their whole lives without complications, and can enjoy aerobic exercise by taking a few precautions

A clear explanation of the affect or exericse, weight training and long term training on resting metabolism and calorie burning.

In most people blood pressure isn't cause for concern unless it causes symptoms such as lightheadedness or fainting.

What is an Exercise Stress Test

How important are genetics in athletic success?

Sudden death in young athletes, while rare, is often the result of underlying heart disease.

Experts who study exercise science have developed some fundamental principles that tend to apply across the board to the way the human body responds and adapts to physical activity. These rules are often referred to as the principles of conditioning.

A study looks at the effect of exercise close to bedtime and sleep.

Sleep deprivation may impair endurance performance and recovery.
