Introduction:
To evaluate the acute effect of resistance exercise performed at different intensities (moderate and vigorous) on urine loss in older women with mixed and stress urinary incontinence.

Methods:
The total of 16 older women with urinary incontinence underwent 2 sessions of resistance exercises involving different muscle groups. In a balanced crossover design, 1 of the 2 exercise intensities (12 or 6 repetitions maximum, RM) was applied in each session. The pad test was used to assess urine loss in the 2 sessions, with a weight increase of 2 g as the criterion. Differences in the pad test results between the sessions were compared with the use of the Wilcoxon test.

Results:
The mean pad weight was 0.69 ± 0.94 g at the intensity of 12RM and 0.50 ± 0.53 g at 6RM. In accordance with the cut-off adopted (2 g), only 2 of the 16 women lost urine. No significant difference in the pad test results (p = 0.975) was observed between the 2 resistance exercise intensities.

Conclusions:
Resistance exercise performed at different intensities (moderate and vigorous) did not cause urine loss in older women with urinary incontinence.
