Movement Specificity: What does it mean? (2012)
Journal Article
Graham-Smith, P., Comfort, P., Jones, P., & Matthews, M. (2012). Movement Specificity: What does it mean?. Professional strength & conditioning,

When an exercise is described as ‘specific’, there is an assumption that the exercise is ‘functional’ and is therefore transferable to a sports skill. Often the main criteria for ‘specificity’ is that the exercise must follow the same movement patter... Read More about Movement Specificity: What does it mean?.
