Liemens raumenų fizinio pajėgumo ir funkcinių judesių sąsajos rankos judesių greičio ir liemens raumenų ištvermės) ir funkcinių judesių stereotipo vertinimas (naudojant FMS sistemą -septyni funkciniai judesiai). Pusiausvyra vertinta flamingo testu, kuris atliekamas kaire ir dešine kojomis. Kairės ir dešinės rankos judesių greitis nustatytas tepingo testu. Lankstumas vertintas testu "Sėstis ir siekti" bei inklinometru, kai vertintas Th12-L1 ir L4-L5 segmentų mobilumas. Liemens raumenų ištvermė vertinta šiais testais: Kraus-Weber testu -pilvo viršutinės dalies raumenų ištvermė, ITO testu -nugaros tiesiamųjų raumenų ištvermė, šoninio tiltelio testu -šoninių liemens raumenų (kairės ir dešinės pusės) ištvermė. Funkciniai judesiai vertinti šiais testais

The aim of this study was to investigate whether torso endurance scores were linked with anthropometric variables in children and to develop a normative scale of anthropometric measures in children in both genders for clinical assessment, rehabilitation, physical education targets and young athletic training purposes. It was hypothesized that changes in anthropometric measures through ages 7 to 14 influence endurance scores in both subsets. It was also hypothesized that boys and girls differ in the relationships between torso muscle endurance and anthropometric measures. Reduced torso muscle endurance has been identified as a potential personal risk factor for developing low back pain and decreased athletic performance. However, torso muscle endurance data in children is lacking. Further, given that endurance tests require postures where the body is supported horizontally, it makes sense that anthropometric variables would influence endurance. Isometric torso muscle endurance scores established through four tests were performed in random order by healthy children. These were correlated with anthropometric dimensions. Seven hundred and fifty-three children from one elementary school (394 boys and 359 girls) were grouped into 8 age strata (7 to 14). Each age stratum had different number of participants for boys and girls. Four tests established isometric torso muscle endurance: Biering-Sorensen test for extensor endurance, flexor endurance test and right and left side bridge tests. The mean, standard deviation of the endurance tests and anthropometric measures were determined for each gender/age strata. The Pearson product-moment correlation coefficients were determined between the anthropometric dimensions and isometric torso endurance scores for each gender/age strata. Variance in endurance scores were not well explained by anthropometric measures. Variables other than segment length and circumference influence torso endurance as children grow and develop. Given links to future back pain and athletic performance, more investigation would be justified.

“…While the etiology and classification of back pain is multifactorial and heterogeneous, there has been research that suggests that it is linked to poor low back muscle endurance (Alaranta, Luoto, Heliovaara, & Hurri, 1995;Biering-Sørensen, 1984;Hultman, Nordin, Saraste, & Ohlsen, 1993;McGill et al, 2003). Modulators of low back muscle endurance include age (Dejanovic, Harvey, & McGill, 2012;Johnson, Mbada, Akosile, & Agbeja, 2009), sex (Mannion & Dolan, 1994;McGill, Childs, & Liebenson, 1999), population, and pathology (Biering-Sørensen, 1984;Sjolie & Ljunggren, 2001). Within individuals, low back muscle endurance can be influenced by biceps femoris involvement (Moffroid, 1997), coactivity of the hip extensors (Kankaanpaa, Taimela, Laaksonen, Hanninen, & Airaksinen, 1998), and postural variance (Dejanovic, Cambridge, & McGill, 2014).…”

“…Part of its wide use is that it is considered a safe, rapid, simple, and reproducible clinical tool for both healthy subjects and patient populations alike. In our previous study (Dejanovic et al, 2012) we noticed that changed neck and head postures may influence the endurance scores. The purpose of this study was to assess low back extensor endurance in children aged 11, as measured by the BST, under a flexed, extended, and neutral head and neck posture.…”

Poor low back muscle endurance has been shown to be a predictor of chronic low back pain. While posture is a modulator of low back muscle endurance, it is unclear whether the phenomenon is neural or mechanical. This study examined low back muscle endurance with changing head and neck posture in a sample of 117 children using the Biering-Sørensen test. Each subject performed the test in a neutral posture followed by randomly selected flexed and extended head and neck positions. Head posture was found to significantly influence low back muscle endurance within subjects (p < .001), with extension yielding the highest endurance scores (boys = 186.6 ± 66.2 s; girls = 192.1 ± 59 s), followed by a neutral posture (boys = 171.3 ± 56.5 s; girls = 181.7 ± 57.3 s), and flexion (boys = 146.2 ± 63.8 s; girls = 159.8 ± 49.3 s). Given the minimal influence of changing moment from head and neck posture, it appears other mechanisms influence endurance score.
