“…It suggests that differently physically active individuals generally have similar levels of muscle stiffness and muscle Vc; at the same time, their levels of twitch force generation speed, muscle responsiveness, and muscle fiber composition are different. These results are in accordance with several previous studies that emphasized the differences in some TMG parameters between differently trained subjects (30,31).…”

Toskić, LD, Dopsaj, MJ, Marković, MR, Toskić, DR, Ignjatović, AM. Mechanical and contractile properties of knee joint muscles measured by the method of tensiomyography in differently trained men and women. J Strength Cond Res 36(6): 1532–1539, 2022—The aim of this study was to investigate the differences in mechanical and contractile properties of knee joint flexor and extensor muscles between differently trained men and women, using tensiomyography (TMG). The sample consisted of 159 subjects (84 men and 75 women), who were assigned to one of 5 groups according to the following levels and types of their physical activity: physically inactive, physically active nonathletes, strength and power athletes, endurance athletes, and team sports athletes. Measurements were performed on the following knee flexor and extensor muscles of the dominant leg: rectus femoris, vastus medialis, vastus lateralis, biceps femoris, and semitendinosus. The results showed significant differences in contraction time—Tc (F = 1.911, p = 0.010) and delay time—Td (F = 1.989, p = 0.007) parameters between differently trained men and women, whereas in other TMG parameters, there were no differences between groups. It is indicated that physical activities characteristic of strength and power sports (combat sports and sprint disciplines) could lead to an increased speed of twitch force generation and fast twitch muscle fibers, and that almost any regular, systematic, and planned physical activity leads to increased muscle responsiveness. Obtained results also indicated that TMG parameters do not have enough specific discriminatory power for detecting differences between differently trained young adults.

“…The findings from the present study show that male professional soccer players have shorter Tc values compared to a sample of the general population who had their RF rectus femoris muscle assessed using TMG. 43 This concurs with Toskic et al, (2016) 44 who reported lower Tc values in the vastus lateralis and the RF muscles of multi-sport athletes relative to aged matched in-active controls. When comparing our study findings to other sporting disciplines, professional soccer players had lower Dm and a lower Tc in the BF muscle relative to elite gymnasts 45 and male triathlon competitors.…”

This study aimed to characterise selected lower-limb muscle contractile properties in a sample of male professional soccer players, and to investigate if muscle contractile properties differed according to playing position or limb dominance. One hundred and ninety-three male professional soccer players (mean ± SD: age=21.6yrs±4.4; height=181.1cm±10.0; body mass=77.4kg±8.5) had bilateral measurements of muscle contractile properties taken during the pre-season period (June-July) of the 2016-17, 2017-18 and 2018-19 seasons using Tensiomyography. The following muscles were measured: Adductor Magnus (AM), Bicep Femoris (BF), Gastrocnemius Lateralis (GL), Gastrocnemius Medialis (GM), Gluteus Maximus (GT) and Rectus Femoris (RF). Participants were sub-categorised by playing position and limb dominance. Data were analysed using Kruskal Wallis H tests or Mann-Whitney U tests. The left GM muscle produced the shortest delay time (Td) (19.5 ms ± 1.9) and contraction time (Tc) (21.3 ms±14.3) whilst the right BF had the longest sustain time (Ts) (196.9ms±83.9). Relaxation time (Tr) was shortest in the right GL (39.3ms±22.7) and the right GT the largest maximal displacement (Dm) value (10.2mm±3.6). Small differences were present between the left AM Td in Forwards (p=0.005, η2=0.05) and Midfielders and in the left GM Ts between Forwards and Goalkeepers (p=0.04, η2=0.02). The right RF Tc measurement was lower in the right dominant participants (p=0.04, η2=0.35). No other differences were detected between playing positions or limb dominance (p>0.05). The findings from this study provide a profile of lower limb muscle contractile properties in a sample of male professional soccer players. The lack of consistent differences reported between sub-categories suggest that soccer players are homogeneous, regardless of playing position or limb dominance. The data generated from this study may be used to monitor soccer players following periods of inactivity, fixture congestion, long-term injury or acute changes in professional status.

“…Regarding the results obtained in non-athletes (Toskić, Dopsaj, Koropanovski, & Jeknić, 2016) it has been determined that their values were higher in Tc, and lower in the Dm variable in relation to our study. The results have indicated that there is a greater muscle stiffness determined in the recreational players, as well as a longer time required for the realization of the 90% complete muscle contractions.…”

The main aim of this study was to define the quantitative neuromuscular characteristics of the Biceps Femoris muscle (BF) as the knee joint flexor, i.e. the major synergist of the caudal body in all specific movement tasks of a football player, measured by the tensiomyography (TMG) method. The secondary aim of the study was to compare all TMG-BF characteristics in relation to bilateral dimorphism, as well as to compare dominant and non-dominant legs. The research was conducted on a sample which included 54 professional players aged 23.0 ± 4.4 years; body height: 182.6 ± 15.1 cm; body mass: 81.2 ± 15.1 kg; BMI: 23.3 ± 1.2 kg/cm 2 . TMG variables were measured on the muscles during a transition training phase (mid-season and end of the season). The results have shown that the average respectively. The results have indicated that there was no statistically significant difference between the examined TMG variables of the dominant and non-dominant leg (Wilks' lambda Value = 0.979, F=0.300, p=0.952, Part. Ƞ 2 = 0.021). It may be stated that there are no differences in the manifestation of neuromuscular characteristics in healthy elite football players regardless of their dominant leg. A high level of preparedness in football in addition to a completely healthy status of the body and locomotor system result in a complete neuromuscular contractile symmetry BF of both legs.
