Abstract

Tensiomyography (TMG) reliability and external validity using maximal voluntary isometric contraction (MVIC) following different strength training protocols (STP) were analysed. Twenty healthy male were tested two times over one week and TMG reliability was analysed in the muscles Rectus Femoris (RF), Biceps Femoris (BF), and Gastrocnemius Lateralis (GL), after an individual maximal and submaximal electrical stimulation. Moreover, TMG external validity was assessed through Pearson correlation between changes in TMG muscle mechanical properties in RF and changes in MVIC in squat exercise after five different lower-limb STPs. Maximal electrical stimulation showed the highest ICC scores for TMG muscle properties reliability in all muscles investigated. Significant Pearson correlation coefficients were found between changes in TMG mechanical properties and changes in MVIC after STPs characterized by high intensity, time under tension and eccentric overload. TMG is a valid and reliable method to assess muscle mechanical properties especially under maximal condition.
