What is Exercise-Induced Tachycardia?

Introduction Tachycardia, also called tachyarrhythmia, is a heart rate that exceeds the normal resting rate. In general, a resting heart rate over 100 beats per minute is accepted as tachycardia in adults. Heart rates above the resting rate may be normal (such as with exercise) or abnormal (such as with electrical problems within the heart).… Read More

What is Athletic Heart Syndrome?

Introduction Athletic heart syndrome (AHS) is a non-pathological condition commonly seen in sports medicine in which the human heart is enlarged, and the resting heart rate is lower than normal. The athlete’s heart is associated with physiological cardiac remodelling as a consequence of repetitive cardiac loading. Athlete’s heart is common in athletes who routinely exercise… Read More

What is the Effect of Cold Water Immersion on Heart Rate Variability in Navy Divers?

Research Paper Title Diving in the Arctic: Cold Water Immersion’s Effects on Heart Rate Variability in Navy Divers. Background Diving close to the Arctic circle means diving in cold water regardless of the time of year. The human body reacts to cold through autonomous nervous system (ANS)-mediated thermoregulatory mechanisms. Diving also induces ANS responses as… Read More

Why the Human Heart needs Exercise

Out of all the organs of the human body, nothing is more fascinating and remarkable than the human heart. It is small, just as the same size as the fist, in proportion to the human body. But as small as it is, it is also a quite formidable organ. It is powerful enough to pump… Read More

Murder: Fitbit Data Used to Charge Suspect

After examining a Fitbit Alta device that Karen Navarra was wearing at the time of her death, police investigators discovered that her heart rate dramatically increased before slowing decreasing and stopping all together – all during a visit with her stepfather, Anthony Aiello. Police investigators in San Jose, California, have recently used a woman’s Fitbit… Read More

Cardiovascular Conditioning: Is Faster Better?

The first step in any conditioning programme is to build an aerobic base. This requires two to four sessions per week of continuous aerobic activity (e.g. jogging or brisk walking) for 15 to 30 minutes at a moderate intensity. The target heart rate for many people during this form of exercise is approximately 130 to… Read More

Physical Activity: Linking Emotion & Metabolic Heart Rate

Research Paper Title Improving Real-Life Estimates of Emotion Based on Heart Rate: A Perspective on Taking Metabolic Heart Rate Into Account. Background Extracting information about emotion from heart rate in real life is challenged by the concurrent effect of physical activity on heart rate caused by metabolic need. “Non-metabolic heart rate,” which refers to the… Read More
