Retention findings revealed an advantage of random practice
. On the contrary, Lin et al.
Compared with blocked practice, in which a skill is learned by repetitive drilling, random practice
, with its frequently modified routine, results in better retention of the skill after training is completed.
Order Several different desired behaviors practiced intermixed in a nonsequential fashion.
Where two groups of subjects practiced three tasks of arm movement, fast and sequenced, under conditions of random practice
and / or by blocks.
When the CI effect was tested in more complex, "real-life" skills, the benefit of random practice
has also been found in several skills, such as badminton serves [10-12], kayaking , rifle shooting , table tennis serves  volleyball skills , baseball batting , and bimanual limb movements .
2011 Abbreviazioni: B = blocked practice; C = gruppo contrallo; F = functional ractice; R = random practice
; S = serial practice.
Furthermore, practicing sports skills according to the game-based training protocol representing a random practice
schedule in an unpredictable environment would be superior to the blocked and random group because of their exposure to the demands of a game and practicing in a similar environment.
The average marginal effect of the stroke QOF score in the third panel data model (random practice
effects with baseline practice mortality) is -0.0000153 and, with a population of 51.1 million with the same characteristics as the sample, this implies that a one unit (1 percent point) increase in the stroke QOF achievement rate would be associated with 782 fewer deaths per year (95 percent CI: 423-1,140).
It can't be just random practice
; it has to be purposeful practice built around a process that can be taught, repeated and coached.
