Farklı yaş gruplarındaki sporcuların denge ve kuvvet performanslarının karşılaştırılması

Abstract

Bu araştırmada farklı yaş gruplarındaki sporcuların kuvvet ve denge performans ilişkilerinin değerlendirilmesi amaçlanmıştır. Araştırmaya minikler ve yıldızlar kategorisinde, farklı spor branşlarıyla ilgilenen toplam 155 sporcu gönüllü olarak katılmıştır. Çalışmaya katılan deneklerin dinamik dengeleri (Y-denge testi), statik dengeleri (Flamingo denge testi) ve kuvvet (kavrama/sırt/bacak) değerleri belirlenmiştir. Katılımcıların tanımlayıcı istatistiklerine ait verilerin ortalama ve standart sapma değerleri hesaplanmıştır. Normal dağılıma uygun olan veriler için ikili gruplar arasındaki farkların incelenmesinde bağımsız örneklem t testi, ikili korelasyonların incelenmesi için ise Pearson korelasyon katsayısı (r) kullanılmıştır. Normal dağılım varsayımını karşılamayan verilerde nonparametrik testler kullanılmış ve ikili grup karşılaştırmaları için Mann-Whitney U testi, ikili ilişkilerin incelenmesi için de Spearman korelasyon katsayısı (ρ) kullanılmıştır. Araştırmada anlamlılık düzeyi 0,01 ve 0,05 olarak kabul edilmiştir. Yapılan analizler sonucunda, kavrama kuvveti (sağ ve sol), bacak kuvveti, sırt kuvveti ve Y denge testi değişkenlerinden kompozit skor (sağ ve sol) değerlerinde yaş grupları arasında yıldızlar kategorisi lehine istatistiksel olarak anlamlı fark bulunmuştur (p<0,01). Flamingo (sağ-sol) test skorlarında ise kategoriye göre anlamlı fark gözlenmemiştir (p>0,01). Kavrama kuvveti (sağ ve sol) ile anterior (sağ ve sol) ve flamingo (sağ ve sol) değişkenleri arasında negatif yönde çok zayıf düzeyde ilişki tespit edilirken, kompozit skor (sağ ve sol) değişkenleri ile pozitif yönde yüksek düzeyde ilişki saptanmıştır. Bacak kuvveti ile posteromedial (sağ) ve posterolateral (sol) arasında pozitif yönde çok zayıf, kompozit skor (sağ ve sol) arasında ise pozitif yönde orta düzeyde ilişki bulunmuştur. Sırt kuvveti ile posteromedial (sağ ve sol) ve posterolateral (sol) arasında pozitif yönde çok zayıf, kompozit skor (sağ ve sol) arasında ise pozitif yönde orta düzeyde ilişki bulunmuştur. Sonuç olarak bu sporcu örneğinde kuvvet performansı ile statik ve dinamik denge değerleri arasında korelasyon saptanmıştır.

Comparıson of balance and strength performances of athletes ın dıfferent age groups

Abstract

The aim of this study was to evaluate the strength and balance performance relationships of athletes in different age groups. A total of 155 athletes from different sports branches in the junior and star categories participated in the study voluntarily. Dynamic balance (Y-balance test), static balance (Flamingo balance test) and strength (grip/back/leg) values of the subjects participating in the study were determined. Mean and standard deviation values of the data belonging to the descriptive statistics of the participants were calculated. For data suitable for normal distribution, independent sample t-test was used to examine the differences between paired groups, and Pearson correlation coefficient (r) was used to examine paired correlations. Nonparametric tests were used for data that did not meet the normal distribution assumption, and Mann-Whitney U test was used for paired group comparisons, and Spearman correlation coefficient (ρ) was used to examine paired relationships. The significance level in the study was accepted as 0.01 and 0.05. As a result of the analyses, a statistically significant difference was found in favor of the star category between the age groups in terms of grip strength (right and left), leg strength, back strength and composite score (right and left) values of Y balance test variables (p<0.01). No significant difference was observed in flamingo (right-left) test scores according to category (p>0.01). While a very weak negative correlation was found between grip strength (right and left) and anterior (right and left) and flamingo (right and left) variables, a high positive correlation was found with composite score (right and left) variables. A very weak positive correlation was found between leg strength and posteromedial (right) and posterolateral (left), and a moderate positive correlation was found between composite score (right and left). A very weak positive correlation was found between back strength and posteromedial (right and left) and posterolateral (left), and a moderate positive correlation was found between composite score (right and left). As a result, a correlation was found between strength performance and static and dynamic balance values in this athlete sample.
