MENSTRUAL DÖNGÜ FAZLARININ TEKRARLI SPRİNT PERFORMANSI VE AKTİF TOPARLANMA ESNASINDA KANDAN LAKTİK ASİTİN UZAKLAŞTIRILMA HIZINA ETKİSİ.

Öz

Bu çalışmanın amacı, menstrual döngünün tekrarlı sprint performansına ve sonrasında aktif toparlanma esnasında laktik asidin kandan uzaklaştırılma hızı üzerine etkisini araştırmaktır. Düzenli menstrual active recovery following to the repeated sprint test. döngüye sahip (menstruasyon gün sayısı = 29.5 r 3.0 gün) 11 sağlıklı kadın sporcuya (yaş = 21.3 r 1.9 yıl, boy = 167.4 r 9.11 cm) menstrual döngünün mid-foliküler (MF) ve luteal fazarında (LF) antropometrik ölçümlerden sonra mekanik bisiklet ergometresinde vücut at the external load corresponding to 10% of the body ağırlıklarının % 10’una karşılık gelen dış dirence karşı weight during mid-follicular (MF) and mid-luteal phases 5 x 6 sn sprint uygulanmıştır. Sprint testini takiben reserv kalp atım hızının %40’ında uygulanan aktif toparlanma esnasında laktik asitin kandan eliminasyon hızı ölçülmüştür. Menstrual döngünün fazlarında vücut ağırlığı (MF = 62.27 r 8.36 kg, LF = 62.26 r 8.42 kg ), vücut yağ yüzdesi (MF = % 21.43 r 3.19, LF = % 21.05 r 3.29), yağsız vücut kitlesi (MF = 48.83 r 6.31 kg, 49.10 r 6.50 kg) benzer bulunmuştur (p>0.05). Ayrıca, MF ve LF’de ölçülen 5 x 6 saniye tekrarlı sprint zirve güç (sırasıyla 13.44 r 1.86 W/kg ve 13.55 r 2.00 W/kg), toplam güç (sırasıyla 62.77 r 8.03 W/kg ve 62.14 r 8.41 W/kg) ve güç kaybı (sırasıyla % 5.53 r 2.22 ve % 6.56 r 2.69) değerleri arasında anlamlı fark saptanmamıştır (p>0.05). MF ve LF’de aktif toparlanma esnasında laktik asitin kandan uzaklaştırılma eğrilerinin eğimleri (MF = -0.19 r 0.05, LF= -0.19 r 0.06) farklı değildir (p>0.05). Aynı şekilde her iki fazda ölçülen zirve laktik asit konsantrasyonlarının yarıya inme süreleri de benzer bulunmuştur (MF = 14.19 r 3.79 dk, LF = 14.39 r 2.36 dk) (p>0.05). Bu araştırmanın sonuçları, menstrual döngü fazlarının tekrarlı sprint performansı ve sonrasında aktif toparlanma esnasında laktik asidin kandan uzaklaştırılma hızı üzerine olumsuz bir etkisi olmadığını göstermiştir
