An exercise mimetic is a drug that mimics some of the biological effects of physical exercise. Exercise is known to have an effect in preventing, treating, or ameliorating the effects of a variety of serious illnesses, including cancer , type 2 diabetes , cardiovascular disease , and psychiatric and neurological diseases such as Alzheimer's ...
In medicine, the pulse is the rhythmic throbbing of each artery in response to the cardiac cycle (heartbeat). [1] The pulse may be palpated in any place that allows an artery to be compressed near the surface of the body, such as at the neck (carotid artery), wrist (radial artery or ulnar artery), at the groin (femoral artery), behind the knee (popliteal artery), near the ankle joint ...
Monitoring of the heart rate can be performed as part of electrocardiography, but it can also be measured conveniently with specific heart rate monitors. Such heart rate monitors are largely used by performers of various types of physical exercise. A generic cardiac monitor has the following functions: A display of heart rate and heart rhythm

This enzyme is responsible for breaking down a molecule called cAMP, which is the key signalling molecule in our body. [31] When PDE3 is inhibited, the breakdown of cAMP is prevented, leading to increased levels of cAMP in our cells. [32] In our heart muscle cells, when the levels of cAMP rise, it activates a protein called protein kinase A ...
The resting heart rate of a newborn can be 120 beats per minute (bpm) and this gradually decreases until maturity and then gradually increases again with age. The adult resting heart rate ranges from 60 to 100 bpm. Exercise and fitness levels, age and basal metabolic rate can all affect the heart rate. An athlete's heart rate can be lower than ...
A cardiac stimulant is a drug which acts as a stimulant of the heart – e.g., via positive chronotropic action (increased heart rate) and/or inotropic action (increased myocardial contractility). They increase cardiac output (the amount of blood pumped by the heart over time).
Researchers hope an exercise-mimicking pill could treat muscle atrophy and improve the physical fitness of people with serious ailments such as cancer and heart failure.
