As coaches, when training with a focus on quantity, we emphasize very much quantitative aspects. This can be reflected in various ways, such as believing that training for longer periods is better than training for shorter periods (a common belief in many Asian countries), thinking that training with higher physiological effort indicators is better than training with lower indicators (a common belief in North America), or that training with more content and number of instructions is better than training with less (a common belief in some European countries).
Training with a focus on quality places great importance on qualitative aspects. To prioritize quality in training, we need to analyze the needs of our players from multiple perspectives: tactical, technical, physical, social, and emotional. Once these needs are identified, we must select the best content and concepts for the training and make physical and psychosocial adjustments. The evaluation of our tasks should not be done in numerical terms or quantity but in relation to the quality of the behavioral changes it generates in the players.
