“…Additionally, Kolka and Stephenson (1997) measured forearm blood flow during leg exercise and demonstrated a higher steady-state blood flow in the luteal phase. Our finding of an unchanged D HHb response in the presence of an unchanged _ VO 2 response is not consistent with these findings but is in agreement with the recent results demonstrating no effect of menstrual cycle phase or estrogen and progesterone on resting calf blood flow (Cooper et al 2006). Thus, in combination, the lack of change in the D HHb-TD and s D HHb accompanying the similar _ VO 2 response in the follicular and luteal phases suggest that there is no effect of menstrual cycle phase on the adaptation of muscle blood flow or O 2 delivery during the transition to moderate-intensity exercise.…”

“…There is evidence that estrogen and progesterone supplementation and the menstrual cycle may alter blood flow control (Sudhir et al 1997;Ettinger et al 1998;Moreau et al 2003;Kirwan et al 2004). However, estrogen and progesterone or menstrual cycle phase has recently been reported to have no effect on resting blood flow (Cooper et al 2006) or on the post-exercise return of blood flow to resting levels (Cooper et al 2006). To date, we are not aware of any studies that have examined the adaptation of muscle blood flow during the transition to exercise in the different phases of the menstrual cycle.…”

O2 uptake and muscle deoxygenation kinetics during the transition to moderate-intensity exercise in different phases of the menstrual cycle in young adult females

O(2) uptake (VO2) kinetics were examined during the follicular (F) and luteal (L) phases of the menstrual cycle to determine if there was an effect of altered sex hormones on the (VO2) response to moderate-intensity exercise. Seven healthy women (age 21 +/- 2 years; mean +/- SD) performed six transitions from 20 W to moderate-intensity exercise (approximately 90% theta L) during the F and L phase. VO2 was measured breath-by-breath and deoxyhemoglobin/myoglobin (Delta HHb) was determined by near infrared spectroscopy. Progesterone and estrogen were significantly (P < 0.05) elevated during the L compared to F phase. VO2 kinetics (tau VO2) were not different in the two phases of the menstrual cycle (F, 22 +/- 5 s; L, 22 +/- 6 s; 95% confidence intervals +/-4 s) nor was the time course of the Delta HHb response (F, TD 11 +/- 2 s, tau 11 +/- 3 s; L, TD 12 +/- 2 s, tau 12 +/- 11 s; tau HHb 95% confidence intervals +/-3 s). Respiratory exchange ratio (RER) was not different between phases for baseline or steady-state exercise and the blood lactate response to exercise was not different. In conclusion, VO2 kinetics at the onset of moderate-intensity exercise are not affected by the phase of the menstrual cycle in young females suggesting either no change in, or no effect of metabolic activation on the on-transient kinetics of moderate-intensity exercise. Additionally, the similar adaptation of Delta HHb in combination with unchanged VO2 suggests that there were no differences in the adaptation of local muscle O(2) delivery.

“…Recent evidence also suggests that menstrual cycle phase has no effect on hemodynamics. For example, Cooper et al (2006) found that suppression of ovarian hormones associated with the menstrual cycle does not affect resting calf blood flow. Finally, although hormonal status was not tracked, all females reported normal cycles (28-30 days).…”

The response of calf muscle strength, resting (R (bf)) and post-occlusive (PO(bf)) blood flow were investigated following 4 weeks resistance training with and without blood flow restriction in a matched leg design. Sixteen untrained females performed unilateral plantar-flexion low-load resistance training (LLRT) at either 25% (n = 8) or 50% (n = 8) one-repetition maximum (1 RM). One limb was trained with unrestricted blood flow whilst in the other limb blood flow was restricted with the use of a pressure applied cuff above the knee (110 mmHg). Regardless of the training load, peak PO(bf), measured using venous occlusion plethysmography increased when LLRT was performed with blood flow restriction compared to no change following LLRT with unrestricted blood flow. A significant increase (P < 0.05) in the area under the blood time-flow curve was also observed following LLRT with blood flow restriction when compared LLRT with unrestricted blood flow. No changes were observed in R (bf) between groups following training. Maximal dynamic strength (1 RM), maximal voluntary contraction and isokinetic strength at 0.52 and 1.05 rad s(-1) also increased (P < 0.05) by a greater extent following resistance training with blood flow restriction. Moreover, 1 RM increased to a greater extent following training at 50% 1 RM compared to 25% 1 RM. These results suggest that 4 weeks LLRT with blood flow restriction provides a greater stimulus to increase peak PO(bf) as well as strength parameters than LLRT with unrestricted blood flow.

“…During the PA tracer study, blood samples for determining PA and CO 2 concentration and enrichment and breath samples for assessment of CO 2 enrichment were obtained at the following times after beginning isotope administration: 180, 240, 300, 360, 380, 400, and 420 min. During each PA tracer study, blood fl ow was measured by venous occlusion plethysmography (345, 365, 385, and 405 min) ( 23 ), and AC profi ling was carried out on blood samples collected at the end of each tracer study (in the fed state). Measurements (15 min) of oxygen consumption and CO 2 production ( V max SPECTRA 29; Sensor Medics Corp., Yorba Linda, CA) were performed at 245 min and 305 min, after the beginning of PA tracer administration.…”
