Acute effect of intensity and volume during strength training on sensation of pleasure, rating of perceived exertion, and pain in trained men
Purpose. The purposes of this study were: (a) to compare the sensation of pleasure, rating of perceived exertion (RPE), and pain in different volumes (volitional failure [VF] vs. fixed repetitions [FR]), equalizing the intensity; and (b) to compare the sensation of pleasure, RPE, and pain in different intensities (40%, 60%, and 80%) of one-repetition maximum (1RM), with equalization of training volume. Methods. A total of 12 trained men (aged 24.9 ± 4.3 years) performed 3 sets of seated row, leg press 180°, and chest press at 3 different intensities (40%, 60%, and 80% 1RM) for both training strategies (VF vs. FR). Results. There was a decrease in pleasure and an increase in RPE and pain in VF training sessions at intensities of 40% and 60% 1RM compared with FR. However, no difference was observed for the intensity of 80% 1RM for pleasure. A doseresponse effect was revealed in the comparison of intensities for pain and RPE. In turn, no effect was found for pleasure. Conclusions. VF training sessions decreased responses regarding pleasure, as well as increased RPE and perceived pain for the intensities of 40% and 60% 1RM when compared with the same intensity in FR among trained men. Different intensities were not able to change the sensation of pleasure
Kinetics of Hypotension during 50 Sessions of Resistance and Aerobic Training in Hypertensive Patients: a Randomized Clinical Trial
Abstract Background: Resistance and aerobic training are recommended as an adjunctive treatment for hypertension. However, the number of sessions required until the hypotensive effect of the exercise has stabilized has not been clearly established. Objective: To establish the adaptive kinetics of the blood pressure (BP) responses as a function of time and type of training in hypertensive patients. Methods: We recruited 69 patients with a mean age of 63.4 ± 2.1 years, randomized into one group of resistance training (n = 32) and another of aerobic training (n = 32). Anthropometric measurements were obtained, and one repetition maximum (1RM) testing was performed. BP was measured before each training session with a digital BP arm monitor. The 50 training sessions were categorized into quintiles. To compare the effect of BP reduction with both training methods, we used two-way analysis of covariance (ANCOVA) adjusted for the BP values obtained before the interventions. The differences between the moments were established by one-way analysis of variance (ANOVA). Results: The reductions in systolic (SBP) and diastolic BP (DBP) were 6.9 mmHg and 5.3 mmHg, respectively, with resistance training and 16.5 mmHg and 11.6 mmHg, respectively, with aerobic training. The kinetics of the hypotensive response of the SBP showed significant reductions until the 20th session in both groups. Stabilization of the DBP occurred in the 20th session of resistance training and in the 10th session of aerobic training. Conclusion: A total of 20 sessions of resistance or aerobic training are required to achieve the maximum benefits of BP reduction. The methods investigated yielded distinct adaptive kinetic patterns along the 50 sessions
