Heart rate response to prolonged standing after head-up tilt was either accentuated or attenuated in the overtrained athletes as compared to the normal training state. We conclude that heavy training could increase cardiac sympathetic modulation during supine rest and attenuated biphasic baroreflex-...
A. Standing heart rate 1. Stand upright for 2 minutes. When the 2 minutes have passed, record your heart rate in Table 6. 2. Locate your heart rate in Table 1 and record the corresponding fitness point value in Table 6. Table 1 ...
If your heart rate doesn’t go down though or your rate increases regularly, speak with your doctor as soon as you can. Some medications cause a rapid pulse, so be sure to tell your doctor about all medications, prescription and over-the-counter (OTC), that you take. Don’t forget ...

The results of the present and other studies [13,15] suggest, that sympathetic heart rate modulation continuously increases during resting position and doing nothing, possibly due to fatigue and/or restlessness. Consequently, the first part of NN interval recording may be significantly different from...
Changes in heart rate asymmetry between high-performance athletes and non-athletes were found under an autonomic function test. Specifically, high-performance athletes manifested a higher number and magnitude of cardiac decelerations than non-athletes after an orthostatic challenge (indicated by GI% and...
Your heart rate generally decreases while you sleep. If you notice that it increases during sleep, it can signalsleep apneaor another underlying cause. If a problem like a dangerous arrhythmia is causing a high heart rate, it can be fatal—and possibly occur without warning. ...
Other factors that can affect your heart rate include: Air temperature. When temperatures or humidity increases, the heart pumps more blood, so your pulse or heart rate may increase. Body position. Sometimes, when going from sitting to standing, your pulse may go up a little. After a few ...
Bradycardia (pronounced bray-duh-kaar-dee-uh) is a slow heart rate. Adults usually have a heart rate between 60 and 100 beats per minute, but if you have bradycardia, your heart beats fewer than 60 beats per minute. EKG readings are the most important test your doctor will use to diagno...
During exercise, your heart rate also increases, as does the delivery of oxygen to the body. Because they're related, VO2 max and heart rate are both valuable tools used to assess a person's level of cardiovascular fitness. Video of the Day ...
