threshold

[′thresh‚hōld]
(building construction)
A piece of stone, wood, or metal that lies under an outside door.
(electronics)
In a modulation system, the smallest value of carrier-to-noise ratio at the input to the demodulator for all values above which a small percentage change in the input carrier-to-noise ratio produces a substantially equal or smaller percentage change in the output signal-to-noise ratio.
(engineering)
The least value of a current, voltage, or other quantity that produces the minimum detectable response in an instrument or system.
(geology)
riegel
(mathematics)
A logic operator such that, if P, Q, R, S, … are statements, then the threshold will be true if at least N statements are true, false otherwise.
(physics)
The minimum level of some input quantity needed for some process to take place, such as a threshold energy for a reaction, or the minimum level of pumping at which a laser can go into self-excited oscillation.
(physiology)
The minimum level of a stimulus that will evoke a response in an irritable tissue.

threshold

1. A strip fastened to the floor beneath a door, usually required to cover the joint where two types of floor material meet; may provide weather protection at exterior doors. Also See doorsill.
2. In illumination engineering, the value of physical stimulus which permits an object to be seen a specified percentage of the time with specified accuracy.

The beginning of that portion of the runway usable for landing (ICAO). On instrument runways, it is indicated by long stripes followed by the runway designation marking. The number of stripes is dependent on the width of the runway.

The Role of Moderate Aerobic Exercise as Determined by Cardiopulmonary Exercise Testing in ALS
Since soccer is a relatively high intensive physical activity so it is not surprising that the reduction in aerobic power, anaerobic power, percentage of maximum oxygen consumption at anaerobic threshold, fat percentage, agility, speed, flexibility, weight and height can cause dysfunction in neurological-muscular and support systems and undermine the performance of the athletes.

In a recent study which retrospectively examined the prognostic value of CPET in 63 patients with IPF, results showed that increased ventilation at anaerobic threshold (AT) as reflected by higher VE/V[O.sub.2] at AT was a major prognostic factor of death [24].

Traditionally, the point of anaerobic threshold was determined by noting an increase in the blood lactate level of the exercising patient, and the term lactate threshold was often used in place of anaerobic threshold.

The concept of the 'anaerobic threshold', although still popular today among certain coaches and exercise scientists, was disproved less than a decade after its inception by George Brooks and his colleagues at the University of California (see review paper (5)).

Effect of exercise at the AT point for children with cerebral palsy
Trained athletes accumulate less lactic acid at a given level of intensity than unfit people do because they've raised their anaerobic threshold. That is, they've enhanced the capacity of the heart and blood vessels to deliver oxygen to the muscles and remove carbon dioxide.

--Aerobic Training in Water Group (ATW, n=7): The animals were submitted to the critical load test to determine the training load, and then performed aerobic training in the aquatic environment for 30 minutes, three times a week, with an intensity corresponding to 70% of the anaerobic threshold with a water temperature of 30[degrees] C ([+ or -] 1).
