Blocked vs Random Practice

When coaching a sport there is a certain way you should structure your practices.  When dealing with a novice athlete you should use more of a blocked practice schedule.  Blocked practice is when a learner performs a single skill over and over, with repetition being the key.  Variance in training is minimized or nonexistent.  The learner then moves on to practice another discrete skill in the same way.1  Random practice is more for athletes that have expertise in the skill and can adjust to changes without much brain interference. In random practice, motor learners work on a number of different skills in combination with each other, randomly working trials and patterns of one and then the next and the next, with each trial interleaved on the previous one.  The random element means the learner is forced to be on his or her toes, not falling into a repetitive routine.1

Blocked Practice
An example of blocked practice in football would be to have your quarterback complete 7 fade routes in a row, then 7 slant routes, and so on.  When training novice athletes you want low contextual interference.  Contextual interference is the impediment in the brain when learning various skills in a limited practice session.  More specifically, low variability is produced when subjects complete all the trials corresponding to one variation of a movement before performing another variation, allowing the athlete to become more comfortable.  This style is more effective with youth sports because it aids in the initial retaining of the skill.  Your quarterback in pee wee football is going to have a one hundred play playbook he has to learn, so you want to make sure he exceeds at the smaller details to get the job done.

Random Practice    
An example of random practice would be a quarterback in a drill reading the defense and deciding where to throw the ball.  In simple terms, random practice setups challenge the learner’s cognitive and motor systems to deal with the interference of each task on the next—an element that keeps him/her on his/her toes and allows for greater retention and skill transfer.1  With an expert like Peyton Manning, the ideal practice is to create a challenge, so that on game day he is ready for what the defenses are going to do.  When an athlete has grasps the skills of the game random practice will help in the advanced areas such as quick movements and brain activity.

Blocked practice is important in the beginning stages of sports, but I think random practice becomes more important the more advanced the game gets.  Most coaches use a combination of the two when practicing.  Start practice with an everyday routine of the basic fundamentals of the sport and then use random practice to make sure the team is prepared for game day.
