Abstract: The allometric theory which describes the relationship between organisms’ structure and their inner function has important implications for comparing different properties of some organisms and has been widely accepted in biology. In recent years, much research has been done on applying the allometric theory to sports sciences in some countries. As a result, the concept of “Normalized Strength”, which is based on the allometric theory, has been developed and used for assessing the muscle strength of individuals of various sizes. This paper analyzed the relevant documents, which were collected from CNKI、PubMed、EBSCO through inputing such keywords as “异速生长”(allometric),“肌力评价”(muscle strength assessment),“allometric scaling”, and “normalized strength”, and concluded that “normalized strength”is a method of converting strength calculations, and has high level of feasibility and validity in that it can rule out the influence of body size on the assessment results. However, the allometric indexes are influenced by many factors, making its application limited. Sports scientific researchers need to resolve this problem in their future work.

Key words: Allometric Scaling, Muscle Strength, Normalized Strength, Assessment Methods
