Amaç: Bioelektrik impedans analizi (BIA) yönteminin geçerliği ve güvenirliği için testten önceki 12-48 saat egzersiz yapılmaması tavsiye edilmektedir. Bu çalışmanın amacı bisiklet ergometresinde tekrarlı sprint egzersizinin ayaktan ayağa (BIAA-A) ve elden ayağa (BIAE-A) BIA yöntemi ile belirlenen vücut kompozisyonu üzerine etkisini incelemektir. Gereç ve Yöntem: Yirmibeş genç aktif erkeğe (23.7±6.3 yaş) bisiklet ergometresinde 5x6 saniye tekrarlı sprint egzersizi yaptırılmıştır. Test öncesinde, testten hemen sonra (1-3 dakika) ve test bitiminin 10. ve 20. dakikalarında katılımcıların vücut ağırlığı (VA), sırasıyla BIAA-A ve BIAE-A yöntemleri ile vücut yağ yüzdesi (VYY), ve yağsız vücut kitlesi (YVK), impedans, rezistans ve reaktans değerleri ölçülmüştür. Egzersizin vücut kompozisyonu ve BIA çıktıları üzerine etkisi tekrarlı ölçümlerde varyans analizi ile belirlenmiştir. Bulgular: Egzersiz öncesiyle karşılaştırıldığında 10. dakikadan itibaren VA’da anlamlı düşüş saptanmıştır (p
Objective: It is recommended not to exercise for 12-48 hours prior to test to secure validity and reliability of bioelectrical impedance analysis (BIA) method. The aim of this study was to examine the effect of repeated cycling sprint exercise on body composition using foot-to-foot and hand-to-foot BIA (BIAF-F and BIAH-F). Material and Method: Twenty five young recreationally active men (23.7±6.3 years) completed a repeated cycling sprint test (5x6-s max sprints with 30 s rest). Body mass (BM), fat-free mass (FFM), body fat percentage (BFP), BIAF-F and BIAH-F, impedance, resistance and reactant values were measured prior to repeated cycling sprint test, immediately after (1-3 minutes) and following 10th and 20th minutes of the test. The effects of exercise on body composition and BIA values were determined by repeated measures variance analysis. Results: When compared to values prior to exercise, significant decrease in BM was found beginning from the 10th minute following the exercise (p
