Mental chronometry is the scientific study of processing speed or reaction time on cognitive tasks to infer the content, duration, and temporal sequencing of mental operations. Reaction time (RT; also referred to as " response time ") is measured by the elapsed time between stimulus onset and an individual's response on elementary cognitive ...
Hemodynamics or haemodynamics are the dynamics of blood flow. The circulatory system is controlled by homeostatic mechanisms of autoregulation, just as hydraulic circuits are controlled by control systems. The hemodynamic response continuously monitors and adjusts to conditions in the body and its environment.
In neuroscience, nerve conduction velocity ( CV) is the speed at which an electrochemical impulse propagates down a neural pathway. Conduction velocities are affected by a wide array of factors, which include age, sex, and various medical conditions. Studies allow for better diagnoses of various neuropathies, especially demyelinating diseases ...
Records 1912–1976. The first manual time of 9.9 seconds was recorded for Bob Hayes in the final of the 100 metres at the 1964 Olympics. Hayes' official time of 10.0 seconds was determined by rounding down the electronic time of 10.06 to the nearest tenth of a second, giving the appearance of a manual time.
Heart rate is the frequency of the heartbeat measured by the number of contractions of the heart per minute ( beats per minute, or bpm). The heart rate varies according to the body's physical needs, including the need to absorb oxygen and excrete carbon dioxide. It is also modulated by numerous factors, including (but not limited to) genetics ...
For a performance to be ratified as a world record by World Athletics, the marathon course on which the performance occurred must be 42.195 km (26.219 mi) long, [34] measured in a defined manner using the calibrated bicycle method [35] (the distance in kilometers being the official distance; the distance in miles is an approximation) and meet other criteria that rule out artificially fast ...
Mile run world record progression. The world record in the mile run is the fastest time set by a runner in the middle-distance track and field event. World Athletics is the official body which oversees the records. Hicham El Guerrouj is the current men's record holder with his time of 3:43.13, [ 1] while Faith Kipyegon has the women's record of ...
Overall speed record is the record for the highest average speed regardless of any criteria, categories or classes that all the more specific records belong to, provided that the route was completed. [1]
