Pētījuma nosaukums. 8-11 gadus vecu futbolistu kāju muskuļu garums un skriešanas ātrums.
Pētījuma mērķis. Noskaidrot kāju atsevišķu muskuļu grupu garumu, 8-11 gadus veciem puišiem, un to saistību ar skriešanas ātrumu.
Pētījuma dizains. Kvantitatīvs šķērsgriezuma pētījums.
Pētījuma metodes. Pētījumā piedalījās 32 dalībnieki, visi bija puiši, 8-11 gadus veci (vidējais vecums bija 9,56 (SD 1,29) gadi), kuri ar futbolu nodarbojas vismaz piecus gadus, un ir treniņi 3 reizes nedēļā. Visiem dalībniekiem tika novērtēts konkrētu muskuļu grupu- Hamstringu, quadriceps femoris un gastrocnemius garums pēc Kendall, locītavu leņķi tika mērīti grādos, un skriešanas ātrums izmantojot 30 metru sprinta skrējienu uz laiku sekundēs.
Datu apstrādes matemātiskās statistikas metodes. Dati tika apkopoti un analizēti SPSS Statistics Data Editor 22.0. Datu analīzei tika izmantota aprakstošā statistika (vidējie lielumi un standarta novirze) un analītiskā statistika (Pīrsona korelācijas koeficients un regresija).
Rezultāti. Vidējā vērtība m.gastrocnemius garumam labajai kājai bija 9,78° (SD 3,54) un kreisajai kājai bija 9,69° (SD 3,08). Abi rezultāti bija statistiski nozīmīgi, labajai kājai rezultāti bija statistiski nozīmīgi 99% līmenī (p = 0,000874) un kreisajai kājai tie bija nozīmīgi 95% līmenī (p = 0,0106). Vidējā vērtība m.quadriceps garums labajai kājai 73.03° (SD 8.06) un kreisajai kājai 72.28° (SD 7.48). Abi rezultāti bija statistiski nozīmīgi – statistisko nozīmīgumu labajai kājai varēja pieņemt 95% līmenī (p= 0,0166) un kreisajai 99% līmenī (p=0,00284). Vidējā vērtība mm.hamstringi garums labajai kājai bija 68.19° (SD 6.22) un kreisajai kājai bija 67.28° (SD 6.39). Abi statistiskās analīzes rezultāti nav statistiski nozīmīgi, labajai (p = 0,642) un kreisajā pusē p vērtība bija ļoti tuvu 1 (p = 0,968).
Secinājumi. Futbolistiem jauniešu vecumā, bija vērojams visu muskuļu- mm.hamstringi, m.gastrocnemius un m.quadriceps saīsinājums. Visvairāk saīsinātais muskulis futbolistiem jauniešu vecumā bija mm. Hamstringi. Gastrocnemius un quadriceps muskuļu garums ir saistīts ar skriešanas ātrumu futbolistiem vecumā no astoņiem līdz vienpadsmit gadiem. Neliels m. gastrocnemius saīsinājums ir saistīts ar labākiem sprinta skriešanas rezultātiem. Normāls quadriceps muskuļa garums norāda uz augstākiem sprinta skrējiena rezultātiem. Hamstringu muskuļu garumam nav saistība ar skriešanas ātrumu futbolistiem vecumā no astoņiem līdz vienpadsmit gadiem.
Research subject. 8 - 11 year old football player leg muscle length and running speed. Goal of the research. Discover the length of different leg muscle groups for 8 to 11 year old boys and their relationship with running speed. Research Design. Quantitative cross section analysis Research methods. There were 32 participants in the research, all of which were male aged 8 to 11 years old (Mean age was 9.56 (SD 1.29) years old). All of the participants had been in football practice for at least five years and had practice 3 times per week. The muscles groups - Hamstring, quadriceps femoris un gastrocnemius muscle length were measured after Kendall, the joint angles were measured in degrees, and the running speed was measured by the time spent running a 30 meter sprint. Data analysis statistical inference methods. The gathered data was analyzed with SPSS Statistics Data Editor 22.0 statistical software. For data inference, summary statistics (Mean and Standard Deviation values) and statistical analysis were used (Pearson Correlation Coefficient and Simple Linear Regression) Results. Mean value for the length of m.gastrocnemius was 9.78° (SD 3.54°) for the right leg and 9.69° (SD 3.08°) for the left leg. Both results were statistically significant, for the right leg the results were significant at the 99% confidence interval (p=0,000874) and for the left leg they were significant at the 95% confidence interval (p = 0,0106). Mean value for the length of m.quadriceps for the right leg was 73.03° (SD 8.06°) and for the left leg it was 72.28° (SD 7.48°). Both results were statistically significant – the significance could be accepted at the 95% confidence interval (p=0,0166) and for the left at the 99% level (p=0,00284). Mean value for the length of mm.hamstring for the right leg was 68.19° (SD 6.22°) and for the left leg it was 67.28° (SD 6.39°). The results were not statistically significant neither for the right leg (p = 0,642) nor for the left leg which had a p-value close to 1 (p = 0,968) Conclusions. Football players which were all at a young age, had noticeably shortened muscles – mm.hamstrings, m.gastrocnemius and m.quadriceps. The most shortened muscle for the young football players was the mm. Hamstring. The gastrocnemius and quadriceps muscle length is correlated with the running speed of football players aged 8 to 11. A slight m. gastrocnemius shortening is correlated with better sprint performance results. Hamstring muscle length has no relationship with running speed for football players aged 8 to 11.
