Introduction: Aging can promote physiological and functional changes that lead to declines in functional capacity, influencing autonomy, joint mobility and inspiratory muscle deficiency, which negatively interferes with postural stability and increases the risk of falling. Objectives: To analyze the effect of high inspiratory demand on balance and risk of falling in the elderly. Methodology: Thirteen elderly men (73 ± 7.25 years) were selected in whom the maximum inspiratory pressure (PImax) was evaluated. Then, the participants performed the Postural Stability Test (PST) and Modified Clinical Test of Sensory Interaction and Balance (m-CTSIB) on the Biodex Balance System (BBS) platform with increased respiratory demand and immediately after the tests. PST and m-CTSIB were performed under three conditions: baseline assessment with free breathing; with an increase in the inspiratory demand (the elderly person breathed through the POWER Breathe Plus HR® equipment with a resistance of 50% of their MIP obtained before the test was performed) and final assessment (immediately after the end of the test with an increase in the inspiratory demand). The conditions analyzed in the m-CTSIB were Eyes Open Firm Surface (EOFS), Eyes Closed Firm Surface (ECFM), Eyes Open Foam Surface (EOFOS) and Eyes Closed Foam Surface (ECFOS). For data analysis, the Shapiro-Wilk and Homogeneity tests were performed using the Levene test, and the One-way Analysis of Variance for repeated measures (ANOVA). All analyzes were performed using SPSS 21.0 adopting p<0.05. Results: In the PST, the values for the stability index were similar in all analyzed variables. In the CTSIB protocol, the pre and during comparison showed significant differences in the EOFS conditions (Pre: 1.03 ± 0.53 and During: 1.70 ± 0.57 with p=0.003), EOFOS (Pre: 1.73 ± 0.50 and During: 3.08 ± 0.80 with p=0.000) and in Fall Risk (Pre: 2.39 ± 0.57 and During: 3.09 ± 0.72 with p=0.001). When these conditions were compared during and after the tests, there were significant differences in all conditions analyzed, namely: EOFS (During: 1.70 ± 0.57 and After: 1.00 ± 0.33 with p=0.000 ), ECFS (During: 1.91 ± 0.75 and After: 1.48 ± 0.54 with p=0.001), EOFOS (During: 3.08 ± 0.80 and After: 2.08 ± 1.24 with p=0.007), ECFOS (During: 5.63 ± 1.80 and After: 4.43 ± 1.25 with p=0.004) and Fall Risk (During: 3.09 ± 0.72 and After: 2, 25 ± 0.57 with p=0.000). And finally, when pre and after were compared, only the ECFOS condition showed a significant difference (Pre: 5.09 ± 1.3 and After: 4.43 ± 1.3 with p=0.040). Conclusions: It is concluded that the overload in the inspiratory demand was able to 9 cause changes in the balance variables, especially when the volunteer is exposed to overload, causing a quick recovery in the period after. The risk of falling was increased with the use of inspiratory overload, which suggests attention to balance in the elderly when inspiratory exercises are prescribed.
