Menstrual Döngünün Koşu Ekonomisine Etkisi: Kalorik Değerlendirme

Abstract

The purpose of this study was to investigate effecst of menstrual cycle on running economy(RE). Eleven healty female athletes (age: 21.18 3.65 year, height:170.2 6.6 cm, VO2max: 49.25 9.15 ml.kgˉ¹.dkˉ¹, menstrual cycle: 29.8 0.98) with a regular menstrual cycle were tested anthropometric variables(Body mass, 7 sum of skinfold, body fat percentage, lean body mass), resting VO2, lactate (LA), heart rate (HR), minute ventilation(VE), respiratory Exchange ratio (RER) and RE was determined at %75 %85 and % 95 of speed at 3.5mmol lactate threshold on running treadmill at midfoliküler(MF) (7-9.days) and luteal phase(LF) (21-23.days) of their menstrual cycle. MF and LF were confirmed by hormonal analyzes(Progesterone MF = 1.79 1.09 nmol.L-1, LF = 37.78 15.08 nmol.L-1; p 0.05, Estradiol MF = 292.68 188.09 pmol.L-1, LF = 589.70 262.25 pmol. L-1; p 0.05).
