NEUROMUSCULAR CHARACTERISTICS OF THE BICEPS FEMORIS MUSCLE IN THE TOP SERBIAN SOCCER PLAYERS MEASURED BY THE TENSIOMYOGRAPHY METHOD: A QUANTITATIVE MODEL.

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/cm². 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 Tc - 32.19 ± 7.64 and 33.21 ± 8.88 ms, Td - 25.56 ± 3.58 and 25.44 ± 3.20 ms, and Dm - 7.39 ± 1.87 and 7.52 ± 2.50 mm, for the dominant and non-dominant leg, 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. Ƞ² = 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.

Glavni cilj ove studije bio je definisanje kvantitativnih neuromišićnih karakteristika mišića Biceps Femorisa (BF) kao pregibača zgloba kolena, odnosno glavnog sinergiste kaudalnog dela tela u svim specifičnim kretnim zadacima fudbalera, utvrđenim primenom tenziometrijske (TMG) metode. Sekundarni cilj studije predstavljao je uporedjivanje svih TMG-BF karakteristika prema bilateralnom dimorfizmu, kao i uporedjivanje dominantne i nedominantne noge. Istraživanje je sprovedeno na 54 profesionalna igrača starosti 23.0 ± 4.4 godina; visine: 182.6 ± 15.1 cm; mase: 81.2 ± 15.1 kg; BMI: 23.3 ± 1.2 kg/cm². TMG varijable su merene na BF mišiću tokom prelazne faze (polusezona i kraj sezone) treninga. Rezultati su pokazali da je prosečno Tc - 32.19 ± 7.64 i 33.21 ± 8.88 ms, Td - 25.56 ± 3.58 i 25.44 ± 3.20 ms, i Dm - 7.39 ± 1.87 i 7.52 ± 2.50 mm, za dominantnu i nedominantnu nogu, respektivno. Rezultati su pokazali da ne postoji statistički značajna razlika između ispitivanih TMG varijabli dominantne i nedominantne noge (Wilks' lambda Value = 0.979, F=0.300, p=0.952, Part. Ƞ² = 0.021). Kod zdravih vrhunskih fudbalera nema nikakvih razlika ispoljavanja neuromišićnih karakteristika BF bez obzira na dominantnost noge. Vrhunska utreniranost u fudbalu u sadejstvu sa potpuno zdravim statusom organizma i lokomotornog aparata uslovljava i potpunu neuromišićno kontraktilnu simetričnost BF obe noge.
