Objective: To evaluate the association between running distance and intensity during high-intensity (HI) and low-intensity (LI) training sessions and sweat loss in elite female soccer players.
Methods: Fifteen elite soccer players from a national team performed two 90-minute training sessions, one at high intensity (HI) and one at low intensity (LI), in a temperate environment. Sweat rate, sodium loss through sweat, and running patterns were measured.
Results: In HI, total distance covered (p<0.001), number of sprints (p<0.001), and total physical load (p<0.001) were higher than in LI. HI also generated a higher sweat rate (p=0.02) and sodium loss through sweat (p=0.03), with no differences in sodium concentration. The sweat rate during HI and LI was associated only with the total distance covered (p=0.02; r=0.47).
Conclusion: In elite female soccer players, high-intensity training induces greater sweat and sodium loss due to a higher sweat rate. Total distance covered appears to be the most influential factor. As a practical application, it is recommended to adjust the rehydration rate to the sweat rate in sessions with greater displacement.
