The authors of this letter wanted to encourage researchers to further investigate measurement properties (validity, responsiveness, and reliability) and applicability of TMG in sports medicine, as this is an assessment tool that, in their experience, may have a great potential to improve the prevention and management of musculoskeletal injuries of athletes.

They pointed out the following:


  • Involuntary
  • Does not affect the performance in subsequent training sessions
  • Individual muscles assessment
  • Large groups (whole team squad) measured in a short period of time


  • Muscles are measured under a static state; no dynamic screening is possible yet
  • No direct assessment of muscular chains is possible
  • Evaluation of deep muscles with current devices is not possible
  • Previous training sessions or competition could affect the data
