The fastest reflex recorded in humans happens within the masseter muscle or jaw muscle. The reflex was measured by electromyography which records the electrical activity during movement of the muscles. This also showed the response latency, or the delay between the stimulus and the response recorded, was found to be about 14 milliseconds.
A list of reflexes in humans. Abdominal reflex; Accommodation reflex — coordinated changes in the vergence, lens shape and pupil size when looking at a distant object after a near object. Acoustic reflex or attenuation reflex — contraction of the stapedius and tensor tympani muscles in the middle ear in response to high sound intensities.
In sports, agility is often defined in terms of an individual sport, due to it being an integration of many components each used differently (specific to all sorts of different sports). Sheppard and Young (2006) defined agility as a "rapid whole body movement with change of direction or velocity in response to a stimulus".
In the late 19th century, tumbling and other acrobatic and gymnastic activities became competitive sport in Europe. Acrobatics has often served as a subject for fine art. Examples of this are paintings such as Acrobats at the Cirque Fernando (Francisca and Angelina Wartenberg) by Impressionist Pierre-Auguste Renoir , which depicts two German ...
Electrical synapses are often found in neural systems that require the fastest possible response, such as defensive reflexes. An important characteristic of electrical synapses is that they are mostly bidirectional, allowing impulse transmission in either direction. [9] [10]
Originally for men only, the 1928 Olympics saw the introduction of women's events in the athletics programme. Athletics is part of the Paralympic Games since the inaugural Games in 1960. Athletics has a very high-profile during major championships, especially the Olympics, even among casual sports fans, but otherwise is less popular though it ...
An ostrich, the co-fastest extant biped [1] along with the red kangaroo, at 70 km/h (43 mph) [2] [note 1]. Bipedalism is a form of terrestrial locomotion where an animal moves by means of its two rear (or lower) limbs or legs.
Sprinting is a sport that requires development of footspeed.. Footspeed, or sprint speed, is the maximum speed at which a human can run. It is affected by many factors, varies greatly throughout the population, and is important in athletics and many sports, such as association football, Australian rules football, American football, track and field, field hockey, tennis, baseball, and basketball.
