Abstract

Bu çalışmanın amacı, atletizm ulusal takımının çeşitli branşlarında yarışan sporcularda plazma 25-hidroksi D [25(OH)D] düzeyleri, antropometrik ve biyokimyasal parametreleri arasında bir ilişki olup olmadığını değerlendirmektir. Çalışmaya 19 kadın (18,63±3,06 yıl) ve 29 erkek (18,90±2,69 yıl) olmak üzere toplam 48 sporcu katılmıştır. Vücut yağ̆ oranının tayini için kaliper yardımıyla deri kıvrım kalınlığı ölçülmüş ve Jackson-Pollock 7 yöntemi ile hesaplanmıştır. Biyokimyasal değerlendirme için plazma 25(OH)D, testosteron, insülin, kortizol, TSH, tiroksin, glukoz, total kolesterol, HDL, LDL ve trigliserid düzeyleri ölçülmüştür. Tüm veriler SPSS18.0. programı ile analiz edilmiş ve p değeri <0,05 olarak kabul edilmiştir. Araştırmamızın sonuçlarına göre ortalama 25(OH)D düzeyi erkek sporcularda 28,37±9,39 ng/ml, kadın sporcularda ise 22,58±8,03 ng/ml olup her iki cinsiyet için de yetersizlik saptanmıştır. Erkek sporcuların vücut yağ oranı %4,42±1,00, kadın sporcuların vücut yağ oranı ise %13,73±3,17 olup 25(OH)D düzeyi ile vücut yağ oranı ve yağsız vücut ağırlığı arasında anlamlı bir ilişkiye rastlanmamıştır. Plazma 25(OH)D düzeyinin kan lipidleriyle ilişkisine bakıldığında, kadın sporcularda total kolesterol düzeyi (p=0,012) ve LDL düzeyi (p=0,013) ile negatif korelasyon göstermiştir. Erkeklerde plazma 25(OH)D düzeyi ile TSH düzeyi ile pozitif korelasyon tespit edilmiştir (p=0,049). Çalışmamızın sonuçları, ulusal takım düzeyinde yarışan sporcularda D vitamini yetersizliği olduğunu ortaya koymuştur. Ayrıca, 25(OH)D düzeyleri ile plazma lipidleri ve bazı hormonlar arasında ilişkinin gözlenmesi D vitamininin enerji metabolizması üzerinde önemli etkilerinin olabileceği görüşünü desteklemektedir.

EVALUATION OF VITAMIN D LEVELS, ANTHROPOMETRIC CHARACTERISTICS AND SOME BIOCHEMICAL PARAMETERS IN NATIONAL ATHLETES

Abstract

The aim of the present study was to evaluate whether there is a relationship between the plasma 25-hydroxyvitamin D [25(OH)D] levels, anthropometric and biochemical parameters of the Turkish national team athletes. A total of 48 athletes, 19 women (18,63 ± 3,06 years) and 29 men (18,90 ± 2,69 years) were included in the study. For body fat ratio, the skinfold thickness was measured by caliper and calculated according to Jackson-Pollock 7 method. Plasma 25(OH)D, testosterone, insulin, cortisol, TSH, thyroxin, glucose, lipids (total cholesterol, HDL, LDL and triglyceride) were measured for the biochemical evaluation. All statistical analyses were performed using SPSS v.18.0. A p value ≤0,05 was considered statistically significant. The mean plasma 25(OH)D levels were 28,37±9,39 ng/ml in males and 22,58±8,03 ng/ml in females. The mean body fat ratio was calculated as 4,42±1% in males and 13,73±3,17% in females. No significant correlation was found between the body fat ratio and 25(OH)D levels. However, a negative correlation was found between the 25(OH)D levels and total cholesterol (p<0,05) and LDL cholesterol (p<0,05) levels in females. There was a positive correlation between the 25(OH)D levels and TSH levels (p<0.05) in males. The results of our study showed a significant 25(OH)D insufficiency in national athletes. In addition, relationships between 25(OH)D levels and plasma lipids and some hormones suggested that 25(OH)D may have significant roles on energy metabolism.
