Fartlek is a Swedish word and roughly translated means 'speed play'. Fartlek training involves varying the intensity or speed of your run to improve your fitness and endurance. ... Fartlek sessions are usually performed for a minimum of 45 minutes and intensity can vary from walking, right up to sprinting.
An echocardiogram checks how your heart's chambers and valves are pumping blood through your heart. An echocardiogram uses electrodes to check your heart rhythm and ultrasound technology to see how blood moves through your heart. An echocardiogram can help your doctor diagnose heart conditions.
Ejection fraction is a measurement of the percentage of blood leaving your heart each time it contracts. The heart contracts and relaxes. When your heart contracts, it ejects blood from the two pumping chambers (ventricles). When your heart relaxes, the ventricles refill with blood. No matter how forceful the contraction, the heart can never pump all blood out of a ventricle. The term "ejection fraction" refers to the percentage of blood that's pumped out of a filled ventricle with each heartbeat. The ejection fraction is usually measured only in the left ventricle (LV). The left ventricle is the heart's main pumping chamber. It pumps oxygen-rich blood up into the upward (ascending) aorta to the rest of the body. An LV ejection fraction of 55 percent or higher is considered normal. An LV ejection fraction of 50 percent or lower is considered reduced. An LV ejection fraction between 50 and 55 percent is usually considered "borderline." Ejection fraction is just one of many tests your doctor may use to determine how your heart works. But even with a normal ejection fraction, your overall heart function may not be normal. Talk with your doctor if you have concerns about your heart. Some things that may cause a reduced ejection fraction are: Weakness of the heart muscle, such as cardiomyopathy Heart attack that damaged the heart muscle Heart valve problems Long-term, uncontrolled high blood pressure
