Maximum number of repetitions performed by resistance-trained men: Effect of maximum load intensity and exercise selection

The purpose of this study was to compare the number of maximum repetitions (RMs) performed at 80% of one-repetition maximum (1RM) and 80% of one-repetition maximum eccentric (1RMecc) test for the preacher-curl (PC) and the bench-press (BP) exercises. Fifteen resistance-trained men participated in this counterbalanced-crossover study. There was no significant difference in the number of RMs performed at 80%-1RM (PC: 7.0±1.2 RMs and BP: 5.8±1.3 RMs) and 80%-1RMecc (PC: 6.0±1.1 RMs and BP: 5.4±1.1 RMs) for both exercises. No significant difference in the numbers of RMs was detected between the PC (80%-1RM: 7.0±1.2 RMs and 80%-1RMecc: 6.0±1.1 RMs) and BP exercises (80%-1RM: 5.8±1.3 RMs and 80%-1RMecc: 5.4±1.1 RMs) for both intensities. In conclusion, the number of RMs performed by resistance-trained men was not affected by the maximum load intensity based on muscle action and the exercise selection

First-ever stroke and transient ischemic attack incidence and 30-day case-fatality rates in a population-based study in Argentina

Background and Purpose - Epidemiological data about stroke are scarce in low- and middle-income Latin-American countries. We investigated annual incidence of first-ever stroke and transient ischemic attack (TIA) and 30-day case-fatality rates in a population-based setting in Tandil, Argentina. Methods - We prospectively identified all first-ever stroke and TIA cases from overlapping sources between January 5, 2013, and April 30, 2015, in Tandil, Argentina. We calculated crude and standardized incidence rates. We estimated 30-day case-fatality rates. Results - We identified 334 first-ever strokes and 108 TIAs. Age-standardized incidence rate per 100 000 for Segi's World population was 76.5 (95% confidence interval [CI], 67.8-85.9) for first-ever stroke and 25.1 (95% CI, 20.2-30.7) for first-ever TIA, 56.1 (95% CI, 48.8-64.2) for ischemic stroke, 13.5 (95% CI, 9.9-17.9) for intracerebral hemorrhage, and 4.9 (95% CI, 2.7-8.1) for subarachnoid hemorrhage. Stroke incidence was slightly higher for men (87.8; 95% CI, 74.6-102.6) than for women (73.2; 95% CI, 61.7-86.1) when standardized for the Argentinean population. Thirty-day case-fatality rate was 14.7% (95% CI, 10.8-19.5) for ischemic stroke, 24.1% (95% CI, 14.2-36.6) for intracerebral hemorrhage, and 1.9% (95% CI, 0.4-5.8) for TIA. Conclusions - This study provides the first prospective population-based stroke and TIA incidence and case-fatality estimate in Argentina. First-ever stroke incidence was lower than that reported in previous Latin-American studies, but first-ever TIA incidence was higher. Thirty-day case-fatality rates were similar to those of other population-based Latin-American studies.Fil: Bahit, M. Cecilia. Ineco Neurociencias Oroño; ArgentinaFil: Coppola, Mariano L..
