1) What does it mean?
Firstly, it can be understood from the mental aspect when the defence focuses on the job at hand. Being alert and giving exclusive attention towards task or object is key. Secondly, the spatial property of being crowded together in a given space[1] can be used. This means that the players position themselves in a way which reduces space and applies pressure on the offensive side, thus making it difficult for them to score. However, both aspects go hand in hand for an effective defence to work. Placing focus and alertness when it comes to positioning as players need to constantly communicate with one another, readjust their positions on court and keeping eye on their given task. Also, regardless of the type of defence being deployed, every player has to fulfill their individual task for the whole system to work. If one player loses concentration, the whole system can be easily broken down by the offensive team.
2) How can it be taught?
Firstly, we specify the sport and the abilities of the students/players. Concentration as a principle of defence is considered part of a defence strategy. When comes to teaching strategy and further on tactic in a team, basic technical skills from the players is the minimum requirement. Also, commitment and many training sessions are needed to hone on this principle as repetitive practice is essential if the team were to perfect the skills and coordination required.
Teaching this principle, a sequence of plays which uses the tactical approach model of student emphasis that leads up to the concentration concept would be designed for basketball. It will be a build up from the individual approach to team approach.
3) Two other defensive principles that are important to the principle of “concentration”
The principles of balance and covering are aligned with the principle of concentration as they complement each other to produce efficient display of defensive play....
