<br/><br/> Background: During the Menstrual cycle (MC), women are exposed to <br/>continuous variations in serum concentrations of several female sex <br/>steroid hormones estrogen, progesterone, follicle stimulating hormone <br/>(FSH), and luteinizing hormone (LH) which are essential to regulate the <br/>patterns of the ovulatory cycle. Purpose: to investigate the impact of the <br/>menstrual luteal phase on an instantaneous muscle torque. <br/>Design: observational cross-sectional study. Subjects: Thirty females <br/>with regular menstrual cycle were recruited from the Egyptian Chinese <br/>University students to participate in this study. <br/> Methods: Females were assigned to one group, and they were all <br/>assessed by isokinetic device to detect the strength and instantaneous <br/>muscular torques of knee extensor firstly during luteal phase (LP) within <br/>19th-20th days of menstrual cycle and then evaluated within 7th-10th days <br/>of their successive menstrual cycle. <br/>Results: There was significant decrease in right and left knee extensor <br/>strength and peak muscle torque during luteal phase compared with that <br/>at 7th-10th days of their successive menstrual cycle. Conclusion: Physical <br/>performance is affected by the different phases of menstrual cycle in the <br/>defined group.   شارك فى هذه الدراسة 30 أنثى فى مجموعة دراسة واحدة بعد الحيض الأخير باربعة عشر يوما وأثناء الحيض وتم تقييمهن جميعا بواسطه جهاز مستوى الحركة للكشف عن القوة وعزم الدوران العضلى اللحظى للعضلة الباسطة للركبة أثناء الطور الأصفرى للحيض ، أظهرت النتائج وجود انخفاض ملحوظ فى القوة والعزم لدى العضلات  الباسطة للركبة فى الطور الأصفرى مقارنة بمرحلة الحيض  ومما سبق يستنتج أن الأداء البدنى يتأثر بمراحل الدورة الشهرية المختلفة فى المجموعة الواحدة ولكنهن قد تختلف حسب الحالة الفسيولوجية والنفسية لكل مشارك <br/>
