Nine resistance-trained eumenorrheic women (age: 28.7 {$\pm$} 3.6 years) were tested in 3 different phases across the MC: menstrual or early follicular phase (i.e., testing between days 1?3), follicular or late follicular phase (i.e., testing between days 7?10), and luteal or mid-luteal phase (i.e., testing between days 19?21). Each testing trial consisted of an incremental loading protocol against 4 loading conditions ({$\approx$}50-70-80-90\% 1RM) in the concentric-only BP exercise. A smartphone application (MyLift) was used to collect the mean velocity (MV) of all repetitions. The 1RM was estimated from the individual load-velocity relationship by applying a linear regression model as the load associated with an MV of 0.17 m?s?1. In addition, the MV obtained at each \%1RM (i.e., from 20\% 1RM to 80\% 1RM in 20\% increments), the load-velocity slope (i.e., the decrease in MV per each 1\% of increment in the \%1RM), and the y-intercept (i.e., the estimate of MV at 0\% 1RM) were computed from the individual load-velocity relationships. No significant differences were observed between the 3 phases of the MC for any of the measured load-velocity relationship parameters (corrected p-value ?0.495; effect size {$\leq$}0.24). The results suggest that the estimation of the BP 1RM from the load-velocity relationship seems not to vary over the 3 different phases of the MC (i.e., menstrual, follicular, and luteal phases).}, keywords = {Female athlete , Ovarian cycle , Training , Velocity-based Resistance training} }
