Abstract
Pētījuma tēma: Muguras lejas daļas aktīvā stabilitāte trenažieru zāles apmeklētājiem.
Pētījuma mērķis: Izpētīt muguras lejas daļas aktīvo stabilitāti trenažieru zāles apmeklētājiem pēc brīvo svaru vingrinājumu pielietošanas.
Metodes: Pētījuma dalībnieki bija 26 fitnesa kluba “People fitness center” trenažieru zāles apmeklētāji, kas atbilda pētījuma iekļaušanas kritērijiem. Dalībnieki pēc nejaušības principa tika iedalīti kontroles un pētāmajā grupā. Pētījuma dalībnieki tika novērtēti, pielietojot muguras lejas daļas aktīvās stabilitātes novērtēšanas testus: aktīvu taisnas kājas pacelšanas testu un m.transversus abdominis iesaistes testu. Dalībnieku novērtēšana tika veikta pētījuma sākumā un atkārtoti pēc četrām nedēļām, pētījuma dalībniekiem apmeklējot trenažieru zāli divas līdz trīs reizes nedēļā. Kontroles grupas dalībnieki veica sevis ierasto treniņu programmu, bet pētāmās grupas dalībnieki veica pētījuma intervenci ar brīvo svaru vingrinājumiem. Pētījuma intervence bija brīvo svaru vingrinājumu programma. Iegūtie dati tika apkopoti protokolā, apstrādāti un analizēti, pielietojot aprakstošās un salīdzinošās statistikas metodes.
Pētījuma rezultāti un secinājumi: Aktīva taisnas kājas pacelšanas testā pēc četrām nedēļām, statistisku nozīmīgu izmaiņu testa rezultāta izmaiņā nenovēro ne kontroles (p= 0,103), ne pētāmajā grupā (p= 0,718). Statistiski nozīmīgu atšķirību aktīva taisnas kājas pacelšanas testā nenovēro arī starp abām pētījuma grupām (p= 0,668). Statistiski ticamu atšķirību m.transversus abdominis iesaistes izmaiņā starp pētāmo un kontroles grupu nenovēro (p=0,123). Tāpat netiek novērota statistiski nozīmīga atšķirība m.transversus abdominis iesaistes izmaiņā kontroles grupas ietvaros pirms un pēc četrām nedēļām (p=0,655), taču novēro statistiski nozīmīgu m.transversus abdominis iesaistes uzlabojumu pētāmās grupas dalībniekiem pēc četrām nedēļām (p=0,008). Pētītajiem trenažieru zāles apmeklētājiem ir raksturīgi muguras lejas daļas aktīvās stabilitātes traucējumi, kas ir samazināta lokālā stabilitātes muskuļa m.transversus abdominis iesaiste un samazināta iegurņa spēja pārnest slodzi no muguras lejas daļas uz kājām. Brīvo svaru vingrinājumi (pētījuma intervence) nedeva statistiski ticamu muguras lejas daļas aktīvās stabilitātes uzlabojumu, taču tika iegūti statistiski nozīmīga m.transverus abdominis iesaistes uzlabošanās petāmās grupas dalībniekiem.
The title: Dynamic stability of lower back for gym attendees. The aim of the study: The aim of this study was to examine the effect of free weight exercises on dynamic lower back stability for gym attendees. Methods: The subjects of the study were 26 fitness club “People fitness center” gym members who met the criteria for inclusion into the study. Participants were randomly assigned to be in the control group and the study group. Participants were evaluated by using lower back dynamic stability tests: active straight leg raise test and m.transversus abdominis involvement test. The evaluation of participants was done before and after four weeks. Participants of the study were attending the gym two to three times per week. Control group went to the gym and did their own training routine while the study group had intervention with free weight exercises. Evaluation data was recorded in protocol, compiled and analyzed by using descriptive and comparative stastistics methods. Results and conclusion: There was no statistically significant difference in Active Straight Leg Raise test after four weeks in control (p=0,103) and study group (p=0,718). There was no statistically significant difference in Active Straight Leg Raise tests results between both groups either(p=0,668). There was no statistically signifficant difference in m.transversus abdominis involvement test between both groups (p=0,123). Also there was no statistically significant difference in m.transversus abdominis involvement test after four weeks in control group(p=0,655), but there was statistically signifficant improvement in activation of m.transversus abdominis in study group subjects (p=0,008). The gym attendees that were subjects of the study had an impaired dynamic stability of lower back, which is decreased activation of local stability muscle m.transversus abdominis and decreased pelvic ability to transfer force from lower back to participants legs. Free weight exercises (intervention of the study) did not provide statistically significant improvement of dynamic stability of lower back but there was statistically significant improvement in activation of transverse abdominal muscle in study group subjects.
