The purpose of this study was to determine the response of selected pulmonary index during the early follicular and luteal phases of the menstrual cycle of active and inactive females during two incremental exercises. The active group included 20 basketball players who were students of Islamic Azad University Central Branch and the inactive group included twenty healthy inactive women who hadnʹt taken part in any regular physical activities and freely volunteered to participate in the study. Each group of participants were randomly classified in two equal groups (Treadmill; T and Cycle Ergometer; CE). The age, weight and height of participants were respectively 22±3 yrs, 52.31±2.44 kg and 165 ±4.50 cm in T: active group and 22±3 yrs, 53.43±4.19 kg and 165±3.77 cm in C: active group. The age, weight and height of participants were 22±3 yrs, 55.32±4.16 kg and 163±5.51 cm in T: inactive group and 22±3 yrs, 56.56±5.78 kg and 162±4.30 cm in C: inactive group. The participants performed an incremental exercise on T and CE during their early follicular and luteal phases until they were exhausted. The luteal phase was determined by the level of Progesterone, Prolactin, FSH and LH hormones in blood samples. In the four groups of participants, the pulmonary gas analyzer (K4B2) was applied to measure the, minute ventilation (VE) in two phases. Paired samples T-tests were performed to detect baseline differences across two menstrual phases in two modes of exercise. Significance was set as 0.05. The results indicated no significant difference of VE in the luteal and early follicular phases of menstrual cycle of active and inactive females in none of the two modes of exercise. Additionally, the differences between average of VE in two modes of exercise were significant in both groups of particiants and, it was more in T than CE (P<0.05). It seems that because of the physical depression during menstrual cycle, which is due to the female inactivity, the replacement of running with cycling, with the aim of making physical activity simpler and encouraging female to continue their activity during this time, is not recommendable.
