Abstract Purpose: The purpose of this study was to compare the acute effects of resistance training (RT) and power training (PT) on the hemodynamic parameters and nitric oxide (NO) bioavailability of older women. Materials and methods: A randomized experimental design was used in this study. Twentyone older women (age: 67.1 +/- 4.6 years

body mass index: 28.03 +/- 4.9 kg/m2

systolic blood pressure: 135.1 +/- 21.1 mmHg) were recruited to participate in this study. Volunteers were randomly allocated into PT, RT, and control session (CS) groups. The PT and RT groups underwent a single session of physical exercise equalized by training volume, characterized by 3 sets of 8-10 repetitions in 8 different exercises. However, RT group performed exercise at a higher intensity (difficult) than PT (moderate) group. On the other hand, concentric contractions were faster in PT group than in RT group. Hemodynamic parameters and saliva samples (for NO quantification) were collected before and during an hour after exercise completion. Results: Results demonstrated post-exercise hypotension during 35 minutes in the PT when compared to rest period (P= 0.001). In turn, RT showed decreased heart rate and double product (P, 0.001) during the whole evaluation period after exercise completion compared with the rest period. NO levels increased in the PT and RT during the whole evaluation period in relation to rest period. However, there were no differences between PT, RT, and CS regarding hemodynamic and NO evaluations. Conclusion: Data indicate that an acute session of power and resistance exercise can be effective to cause beneficial changes on hemodynamic parameters and NO levels in older women.
