This study examined differences between high intensity, intermittent work in two phases of the menstrual cycle. Six physically active young women (age 19-29) performed 10 6-s sprints on a cycle ergometer in both the mid-follicular (FP) (days 6-10) and late-luteal phases (LP) (days 20-24) of the menstrual cycle. Work, power, oxygen intake $$ {\left( {\ifmmode\expandafter\dot\else\expandafter\.\fi{V}{\text{O}}_{2} } \right)} $$ parameters, and capillarized blood lactate were measured. Data are analyzed using the Friedman and Wilcoxon matched pairs tests. There was no difference between menstrual phases in peak 6-s power (6.8(0.6) Wkg−1 in FP, 6.9(0.6) Wkg−1 in LP), the drop off in work (1.2(3.5) Jkg−1 in FP and 1.0(2.7) Jkg−1 in LP), or in the sprint $$ \ifmmode\expandafter\dot\else\expandafter\.\fi{V}{\text{O}}_{2} $$ (23.7 (1.5) mLkg−1min−1 in LP and 24.3(2.4) mLkg−1min−1 in FP). Capillarized blood lactate was also similar in both phases of the menstrual cycle both at 1min (9.2 (2.7) mmolL−1 in FP, 9.2 (3.1) mmolL−1) and at 3min(9.0 (2.2) mmolL−1 in FP, 9.2 (2.2) mmolL−1 in LP). However, the average 6-s work was greater in the LP (39.3 (3.4) Jkg−1) than during the FP (38.3 (3.1) Jkg−1) (P=0.023). The recovery $$ \ifmmode\expandafter\dot\else\expandafter\.\fi{V}{\text{O}}_{2} $$ was also greater in the LP than the FP (26.3 (2.4) mLkg−1min−1 in LP, 25.0 (2.6) mLkg−1min−1 in FP, P=0.023). Average work over a series of sprints and the $$ \ifmmode\expandafter\dot\else\expandafter\.\fi{V}{\text{O}}_{2} $$ consumed between sprints may be slightly greater during the LP than the FP of the menstrual cycle.
