Düzenli Egzersiz Yapmayan Genç Kadınlarda Sekiz Haftalık Reformer Pilates Sürecinde Antropometrik Çevre Ölçümleri ve Biyoelektrik İmpedansa Dayalı Vücut Kompozisyonundaki Değişimler

Öz

Pilatesin vücut kompozisyonuna etkileri tutarsızdır; süreçteki değişimleri izleyen çalışma sayısı azdır. Amaç: Gözetimli Reformer Pilates boyunca vücut ağırlığı, biyoelektrik impedansla belirlenen vücut yağ yüzdesi ve kas kütlesi ile yedi çevre ölçümünü başlangıçta, 4. ve 8. haftalarda değerlendirmek amaçlanmıştır. Yöntem: Son altı ayda düzenli egzersiz yapmamış, 18–24 yaşlarındaki 22 kadın, haftada iki kez 50–60 dakika süren 8 haftalık programa katılmıştır. Sonuçlar Greenhouse–Geisser düzeltmeli tekrarlı ölçümler ANOVA ile analiz edilmiş; 10 sonuç için Holm, ikili karşılaştırmalar için Bonferroni düzeltmesi uygulanmıştır. Duyarlılık analizlerinde Friedman testi kullanılmıştır. Bulgular: Vücut ağırlığı, vücut yağ yüzdesi ve kas kütlesinde anlamlı zaman etkisi görülmemiştir (Holm-düzeltilmiş P=.952, 1.000 ve 1.000). Yedi çevre ölçümünün tamamında zaman etkisi anlamlıdır (Holm-düzeltilmiş P≤.041). Başlangıçtan 8. haftaya azalmalar kol çevresinde 0,95 cm, karın çevresinde 5,32 cm olmuştur. Karın çevresi 83,55±8,35 cm’den 78,23±6,23 cm’ye düşmüştür (düzeltilmiş P<.001; kısmi η²=.515). Düzeltme sonrası 4. ve 8. hafta karşılaştırmalarının hiçbiri anlamlı değildir. Sonuç: Kontrol grubu olmayan programda bazı çevre ölçümleri azalırken vücut ağırlığı ve biyoelektrik impedans tahminlerinde anlamlı zaman etkisi saptanmamıştır. Çevre ölçümlerindeki farklılıkların çoğu 4. haftada görülmüştür.

Temporal Changes in Anthropometric Circumferences and Bioimpedance-Derived Body Composition During Eight Weeks of Reformer Pilates in Young Women Without Regular Exercise Participation

Öz

Background: Evidence on Pilates-related body composition is inconsistent, and few studies track changes during programs. Objective: To assess body mass, bioimpedance-derived body-fat percentage and muscle mass, and seven circumferences at baseline, week 4, and week 8 of supervised Reformer Pilates. Methods: Twenty-two women aged 18–24 years who had not exercised regularly in the previous six months completed an 8-week program (two 50–60-min sessions weekly). Repeated-measures ANOVA with Greenhouse–Geisser correction was used; Holm adjustment covered 10 outcomes, with Bonferroni-adjusted pairwise comparisons and Friedman sensitivity tests. Results: Body mass, body-fat percentage, and muscle mass showed no significant time effects (Holm-adjusted P=.952, 1.000, and 1.000). All seven circumferences showed significant time effects (Holm-adjusted P≤.041). Baseline-to-week-8 reductions ranged from 0.95 cm (arm) to 5.32 cm (abdomen). Abdominal circumference decreased from 83.55±8.35 to 78.23±6.23 cm (adjusted P<.001; partial η²=.515). No week-4-to-week-8 comparison remained significant. Conclusions: During this uncontrolled program, several circumferences decreased, but body mass and bioimpedance-derived estimates showed no significant time effects. Most detectable circumference differences were evident by week 4.
