The Limitations of Group-Based Models

Traditional research methods often rely on average results from a group of participants to draw conclusions about individual movement behaviors. This approach tends to overlook significant individual variability, as demonstrated by studies like the one on golfers where averages can mask substantial differences in shoulder rotation among individuals. The issue with averaging is that it may represent a mythical average performer, which doesn't accurately capture the distinct movement solutions utilized by individuals. As a result, using group-based models can lead to misleading recommendations that fail to consider the unique adaptations and strategies of each person.
