The aim of this study was to analyse whether the modification of training tasks, specifically spatial orientation, had consequences on the different parameters that identify training load in women's football. Eighteen female football players participated (M = 21.89; SD = 6.20) completing two sessions of four tasks each. The tasks were counterbalanced within each session to prevent the effect of order. GPS Polar Team Pro was used to measure physical load and questionnaires were applied to assess mental load. A repeated-measures T-test was conducted to compare the results of each session. The results showed that physical load was higher in tasks with no orientation, and the same occurred with mental load. Therefore, the space in which training tasks are performed is determining in perceived mental load in women's football.
