Comparison of Weekly Training Loads in Division I Lacrosse Athletes Using Hormonal Contraceptives Versus Nonusers.

Coleman, E, Honeycutt, S, Humphries, H, Gao, D, and Bunn, JA. Comparison of weekly training loads in Division I lacrosse athletes using hormonal contraceptives versus nonusers. J Strength Cond Res 40(9): 1143-1146, 2026-Approximately half of female collegiate athletes use hormone contraceptives (HC), but little attention has been paid to see if there are effects of HC use on performance. This study explored workload differences among Division I, female lacrosse players' objective performance during the competitive season for those using HC ( n = 16) and those not ( n = 8). Data were collected on all training days and game days during the 16-week competitive season via global positioning system units. The workload variables used included total distance (m), maximum speed (km·h -1 ), number of accelerations and decelerations completed at >3 m·s -2 , metabolic equivalent distance (m), and meters sprinted at >90% maximum sprint speed (zone 5 distance). Weekly sums for each variable were tabulated for each athlete and used for comparisons. A Bayesian hierarchical linear regression model was used to determine group differences. The results showed no group differences in weekly summed workload across any of the weeks assessed (all p > 0.05). These data suggest that workload differences are not solely related to the use of an HC or not. These results differ from previous literature, warranting more exploration in the role of HC use with athlete performance. An individualized approach to understanding performance differences with HC use is warranted.
