20.500.12556/RUL-185116 Primerjava akutnih vplivov valjčkanja in statičnega raztezanja na gibljivost sprednje stegenske mišice Comparison of acute effects of foam rolling and static stretching on the flexibiltiy of the hip flexors Namen raziskave je bil primerjati akutne učinke statičnega raztezanja in valjčkanja na gibljivost sprednje stegenske mišice ter ugotoviti morebitne razlike v učinkovitosti navedenih metod. V raziskavi je sodelovalo 15 zmerno aktivnih mladih odraslih, ki so v dveh ločenih obiskih izvedli obe intervenciji. Obseg gibljivosti smo ocenili z merjenjem pasivnega upogiba kolena in aktivnega iztega kolka z uporabo digitalnega inklinometra. Obe intervenciji sta povzročili statistično značilno povečanje obsega gibanja v obeh sklepih (p < 0,001), z zmernim učinkom pri upogibu kolena (d = 0,47–0,61) in velikim učinkom pri iztegu kolka (d = 0,85–0,92), pri čemer med metodama ni bilo razlik v učinkovitosti (p < 0,05). Statično raztezanje domnevno poveča gibljivost predvsem prek izboljšane tolerance na razteg, medtem ko valjčkanje deluje z zmanjšanjem mišične napetosti in vplivom na fascialne strukture. Rezultati podpirajo uporabo obeh tehnik kot enakovrednih orodij za akutno izboljšanje gibljivosti sprednje stegenske mišice. Nadaljnje raziskave bi morale vključevati večje in raznolike vzorce ter primerjati kratkoročne in dolgoročne učinke teh metod, posamično in v kombinaciji. The aim of this study was to compare the acute effects of static stretching and foam rolling on the mobility of hip flexors (m. quadriceps) and to determine any differences in the effectiveness of the two methods. Fifteen moderately active young adults participated in the study and completed both interventions in two separate sessions. Range of motion was assessed using a digital inclinometer to measure passive knee flexion and active hip extension. Both interventions led to statistically significant increases in joint range of motion (p < 0.001), with moderate effect sizes for knee flexion (d = 0.47–0.61) and large effect sizes for hip extension (d = 0.85–0.92). No significant differences in effectiveness were observed between the methods (p > 0.05). Static stretching is presumed to enhance flexibility primarily by increasing stretch tolerance, whereas foam rolling likely exerts its effect by reducing muscle tension and influencing fascial structures. These findings support the use of both techniques as equally effective tools for the acute improvement of anterior thigh muscle flexibility. Future research should include larger and more diverse samples and evaluate both the short- and long-term effects of these methods, individually and in combination. šport raztezanje valjčkanje obseg giba sprednja stegenska mišica gibljivost akutni učinki sport stretching foam rolling range of motion anterior thigh muscle mobility acute effects true false true Slovenski jezik Angleški jezik Članek v reviji 2026-07-23 11:27:40 2026-07-23 11:27:42 2026-08-07 09:48:12 0000-00-00 00:00:00 2025 0 0 Str. 170-176 št. 3/4 Letn. 73 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 796.01 3024-0603 10.52165/sport.73.3-4.170-176 265286403 SPORT+3-4-25_170-176_Pletikos.pdf SPORT+3-4-25_170-176_Pletikos.pdf 1 98FBCF9D4D975C20B54AFBCEA13B37C8 b87b90254bafe25ccc87e94307f1431a0a8c577b722749c688ce4105924daa73 05642a96-867a-11f1-9b0d-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=243326 https://journals.uni-lj.si/sport/article/view/23249 1 84446bb3-8678-11f1-9b0d-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=243325 Fakulteta za šport Šport 0 0 0
