This study aimed to evaluate the postactivation potentiation (PAP) effects following eccentric overload (EOL) exercises on change of direction (COD) performance and muscle contractile function. Muscle contractile function was assessed by tensiomyography (TMG) such as muscle contraction time (Tc), time delay (Td) and displacement of the muscle belly (Dm) of vastus lateralis (VL), vastus medialis (VM), and rectus femoris (RF). Eccentric overload exercises were: (a) cross-cutting step with inertial conical pulley (INC = 11 subjects), (b) flywheel leg extension (EXT = 10 subjects), and flywheel yo-yo squat exercise (SQU = 10 subjects). Differences baseline-post were found on COD-5mD (p < 0.001) and on COD-5mND (p < 0.001), but not between groups (p > 0.05) following EOL exercises. This study reported a significant positive PAP response after 4 minutes of recovery after EOL exercises (INC, EXT and SQU) in soccer players. For the first time, it has been reported that EOL exercises acutely affect Tensiomyography TMG variables (e.g., Tc and Td) in lower limbs. Such results related to changes in muscular contractile functions may contribute to explain the physiological mechanisms (e.g., neuromuscular factors) associated with PAP effect.

Dr. Vernon William is a founding Director of Center for Sports Neurology and Pain Medicine at Cedars-Sinai Kerlan-Jobe Institute and they have published how Tensiomyography (TMG™) assessments gives them information on how muscles are working, inform how muscle function is affected and what possible limits may occur in performance.
It was a busy month. We completed testing of our National football teams from U15 to U19 and WU17 to WU19. Our Tensiomyography (TMG) technology was used to assess muscle performance of our young athletes. TMG adds a clear, objective comparison of a normal muscle’s actions and a likely muscle impairment. Since the information is objective and quantified, it’s a permanent record of how the muscles trend over a season.

An exhaustive review has been made to filter the studies that have analyzed muscle function though tensiomyography (TMG) with elite or well-trained athletes. The results of this review indicate that the several protocols used in athletes to find the displacement-time curve with greater maximum radial muscle displacement showed a good-excellent reliability.
Tensiomyography (TMG) had proven once again its usability when very repeatable and sensitive methodology is required to follow changes in muscle contractile properties.
Information about the speed of muscle contraction was very useful to detect effect of local muscle fatigue.
The tensiomyography (TMG) technique is increasingly used to determine muscle contractile properties in exercise and injury management. The present study investigated the informative value of TMG parameters in correlation with commonly used (creatine kinase, CK; myoglobin, Mb) and novel candidate biomarkers of muscle damage (heart-type fatty acid-binding protein, h-FABP; high-mobility group box 1, HMGB1).

New article was published in Journal of Applied Physiology and it’s about using Tensiomyography to detect changes in muscles as a consequence after lack of movement.
We are leaving in the world facing aging of the population and anti-aging research are gaining importance.
This article demonstrate how useful can be the information provided by Tensiomyography . Full article
