A compulsion loop, reward loop or core loop is a habitual chain of activities that a user may feel compelled to repeat. Typically, this loop is designed to create a neurochemical reward in the user such as the release of dopamine.
Snap, [6] or jounce, [2] is the fourth derivative of the position vector with respect to time, or the rate of change of the jerk with respect to time. [4] Equivalently, it is the second derivative of acceleration or the third derivative of velocity, and is defined by any of the following equivalent expressions: = ȷ = = =.
Jumping with weights or throwing weights are two examples of power training exercises. Regular weight training exercises such as the clean and jerk and power clean may also be considered as being power training exercises due to the explosive speed required to complete the lifts. Power training may also involve contrasting exercises such as ...
In the power jerk or push jerk, the lifter performs the same dip and jump movement, but unlike the split jerk, the lifter catches the barbell in a partial squat position. Power jerk may be used synonymously with push jerk, but a distinction may be made with push jerk being a type of power jerk where the feet stayed connected to the platform ...

The Jendrassik maneuver to reinforce knee-jerk. The Jendrassik maneuver is a medical maneuver wherein the patient clenches the teeth, flexes both sets of fingers into a hook-like form, and interlocks those sets of fingers together. The tendon below the patient's knee is then hit with a reflex hammer to elicit the patellar reflex. The elicited ...
Mechanisms that would explain the power law were popularized by Fitts and Posner (1967), [4] Newell and Rosenbloom (1981), [5] and Anderson (1982). [6] However, subsequent research by Heathcote, Brown, and Mewhort suggests that the power function observed in learning curves that are averaged across participants is an artifact of aggregation. [7]
Neuroplasticity is the process by which neurons adapt to a disturbance over time, and most often occurs in response to repeated exposure to stimuli. [27] Aerobic exercise increases the production of neurotrophic factors [note 1] (e.g., BDNF, IGF-1, VEGF) which mediate improvements in cognitive functions and various forms of memory by promoting blood vessel formation in the brain, adult ...
