Morales, et al. have recently published an article in which they investigate the efficacy of tensiomyography (TMG) in assessing muscle contractile function at acute moderate altitude. Biceps femoris (BF) and vastus lateralis (VL) muscles of 18 athletes were assessed at sea level and moderate altitude by using electrically evoked contractions on two consecutive days. Maximum radial displacement (Dm), time of contraction (Tc), reaction time (Td), sustained contraction time (Ts), and relaxation time (Tr) were recorded at 40, 60, 80, and 100 mA. At altitude, VL showed lower Dm values at 40 mA (p = 0.008; ES = -0.237). Biceps femoris showed Dm decrements in all electrical stimulations (p < 0.001, ES > 0.61). In VL, Tc was longer at altitude at 40 (p = 0.031, ES = 0.56), and 100 mA (p = 0.03, ES = 0.51). Regarding Td, VL showed significant increases in all electrical intensities under hypoxia (p ≤ 0.03, ES ≥ 0.33). They conclude that TMG appears effective at detecting slight changes in muscle contractile properties at moderate altitude.

In the recent article published in the BJSM, professor Ekstrand and his colleagues have evaluated the Munich consensus on muscle injury classification. They conclude the study with the words that even though the Munich muscle classification demonstrates a positive prognostic validity for the return to play after a thigh muscle injury in professional male football players, there are still many opportunities for improvement, especially in the field of functional muscle disorders. Unlike with the structural muscle disorders, functional disorders cannot be diagnosed and monitored with an MRI or other widely used methods. They do not provide useful information in later stages when the muscle structure recovers, yet the muscle function stays impaired. Only methods such as tensiomyography evaluate muscle function. With the implementation of such methods, functional muscle disorders can be detected and treated in an efficient manner, which leads to a faster RTP and lower re-injury rates.

Our recently developed M-wave module is now available. The M-wave module measures the electrical activity of muscles after electrostimulation. In combination with the TMG system, it provides additional information on muscle status and ratio between the quality of the stimulated muscle fibers (M-wave) and their ability to contract (TMG). This enables us to monitor the progression of muscle disorders, physical fitness, etc. The first module has already been sent to the Kokushikan University in Japan where it will be used in combination with TMG and ‪MC.‬‬ Contact us for more information.

Juan Manuel García-Manso and his associates have recently published a study on the effect of different types of stretching on muscle response using tensiomyography. More specifically, tensiomyography was used to examine the changes observed in the response of the biceps femoris muscle of the dominant leg of ten young female gymnasts after performing two different stretching protocols: contract-relax (CR) and static-stretching (SS). The results revealed a change of muscle response immediately after warm-up: increased velocity of deformation, stiffness, holding time and reduced relaxation time. The changes were most evident in the first three minutes after applying the two stretching protocols, being more evident in CR than in SS. The results suggest that athletes who include stretching in their warm-up will find the post warm-up mechanical response less impaired after the first three minutes and more so when using the techniques based on working with static-stretching, compared to techniques based in contract-relax.
