SU ALTI YAĞ YÜZDESİ ÖLÇÜMÜ VE DERİ KIVRIM YÖNTEMLERİ İLE BELİRLENEN VÜCUT YAĞ ORANLARINDA FARKLI GÖZLEMCİ RAPORLARININ TUTARLILIĞI

Bu çalışmanın amacı, sualtı vücut yağ yuzdesine karsilik BF% için deri kıvrımı SK antropometri hassasiyetini araştırmak ve deri kıvrımı değerlendirmelerde cinsiyet farklılıkların ve grupici gozlemciler ve gözlemciler arası tutarlılık in olup olmadigini incelemktir. On erkek ve on kadın denek 5 ayrı deri kıvrım ölçümleri aldı, 5 ayrı gözlemcinin aldigi degerler değişkenliği bulmak için değerlendirildi. Pearson testi erkek ve kadın denek geçerliliğini değerlendirmek üzere bagimsiz olarak deri kıvrım ölçümleri ve sualtı tartım teknikleri arasındaki korelasyon test etmek için kullanıldı. Erkekler kadınlara göre grupici ve gözlemciler arasindaki tutarsızlık daha fazla miktarda olma eğiliminde olsa da, bu fark anlamlı değildi. Geçerlilik dikkate alındığında, deri kıvrım ölçümleri ve erkek ve kadınlar arasındaki sualtı arasında anlamlı bir fark yoktu. Değişkenlik gözlenen farklılıklar kadın ve erkek arasındaki deri kıvrımı sıkıştırılabilirliğinden kaynaklanan bir fark olduğu gerçeği ile açıklanabilir.

DETERMINATION OF İNTRAOBSERVER AND İNTEROBSERVER VARİABİLİTY WITH THE ASSESSMENT OF UNDERWATER WEIGHING AND SKINFOLD MEASUREMENT METHODS12

The purpose of this study was to investigate the precision of skinfold SK anthropometry to evaluate percentage body fat BF % against underwater weighing UW and find out if sex differences in skinfold assessments would be apparent in intraobserver and interobserver consistency as well as validity when compared with underwater weighing UW measurements. Ten male and ten female subjects were assessed to find out intraobserver and interobserver variability by 5 separate observers who each took 5 separate skinfold measurements. Pearson test were used to test correlations between skinfold measurements and underwater weighing techniques for male and female subjects were plotted independently to assess validity. Although men tended to have greater amounts of intraobserver and interobserver inconsistency when compared with women, these differences were not significant. In consideration to validity, there was no significant difference between skinfold measurements and underwater weighing between man and women. The differences observed in variability could be explained by the fact that there is a difference in skinfold compressibility between men and women
