Resting energy expenditure (REE) is the number of calories burned in a day without strenuous activity. It is difficult to measure accurately, but formulas and methods like calorimeters and gas analysis can provide an estimate. Knowing REE can help maintain weight and guide daily caloric intake. Resting energy expenditure (REE) is a term that describes […]
Resting metabolic rate (RMR) is the energy used by the body at rest to maintain basic life functions. It varies based on weight, age, height, gender, physical activity, muscle mass, and normal caloric intake. RMR is important in designing a successful weight loss program, and can be increased through smaller, more frequent meals and exercise, […]
Rest pain is a constant burning, tearing, aching, or shooting sensation in the lower leg, toes, or feet caused by reduced blood flow. It could be a symptom of lower extremity arterial disease, and individuals experiencing rest pain should ensure that they check their feet often and thoroughly for signs of gangrene. Simple lifestyle changes […]
All cells have a resting membrane potential, which is the voltage difference between the fluids inside and outside the cell. This is important for transmitting electrical signals in nerve and muscle cells. The voltage difference is maintained by channels that control the flow of ions, such as potassium and sodium. When a cell receives a […]
Resting potential is the voltage difference across a cell membrane, maintained by protein ion channels and pumps. Neurons and muscle cells use it to effect changes. Sodium and potassium ions are involved in creating and maintaining the resting voltage. Calcium ions are important in maintaining the resting membrane potential in muscle cells. The resting potential […]
Resting heart rate is the number of times the heart beats when the body is at rest. The best time to measure it is before getting out of bed in the morning. The average resting heart rate for adults is between 60-80 bpm, and it’s important to calculate it to determine target heart rate during […]
Resting ECG measures the electrical activity of the heart using adhesive skin electrodes placed on specific points. It is used to determine heart health and diagnose problems. Exercise ECG is used to determine how much work a patient’s heart can handle. The electrocardiogram (ECG or EKG) is a test that measures the electrical activity of […]
