Effect of Different Interset Rest Intervals on Performance of Single and Multijoint Exercises With Near-Maximal Loads.

The aim of this study was to investigate the acute effects of different interset rest intervals on performance of single- and multijoint exercises with near-maximal loads. Fifteen trained men (26.40 ± 4.94 years, 79.00 ± 7.10 kg, 176.6 ± 6.06 cm, 11.80 ± 2.47% body fat, and bench press relative strength: 1.26 ± 0.19 kg·kg of body mass) performed eight sessions (2 exercises × 4 interset rest intervals); each consisting of 5 sets with a 3RM load. The exercises tested were the machine chest fly (MCF) for the single-joint exercise and the barbell bench press (BP) for the multi-joint exercise with 1, 2, 3, and 5 minutes of rest between sets. The results indicated that for the MCF, significantly higher total number of repetitions were completed for the 2- (12.60 ± 2.35 reps; p = 0.027), 3- (13.66 ± 1.84 reps; p = 0.001), and 5-minute (12.93 ± 2.25 reps; p = 0.001) vs. the 1-minute (10.33 ± 2.60 reps) protocol. For the BP, a significantly higher total number of repetitions were completed for 3- (11.66 ± 2.79 reps; p = 0.002) and 5-minute (12.93 ± 2.25 reps; p = 0.001) vs. the 1-minute protocol (7.60 ± 3.52 reps). In addition, subjects completed significantly higher total number of repetitions for the 5-minute (12.93 ± 2.25 reps; p = 0.016) vs. 2-minute (9.53 ± 3.11 reps) protocol. Both exercises presented similar and progressive reductions in repetition performance for all rest protocols along the 5 sets, starting as soon as the second set for the shorter 1-minute rest protocol. In conclusion, to maintain the best consistency in repetition performance, rest intervals of 2 minutes between sets are sufficient for the MCF and 3-5 minutes for the BP. Thus, it appears that longer acute recovery time is needed for a multijoint (core) exercise such as the BP vs. a single-joint (assistance) exercise such as the MCF.

Internações por condições sensíveis à atenção primária após a implantação da estratégia saúde da família no município de Petrópolis/RJ / Hospitalizaciones por enfermedades sensibles a la atención primaria después de la implementación del programa de salud de la familia enmunicípio de Petrópolis/RJ / Hospitalizations due to primary care sensitive conditions after family health strategy implementation on Petrópolis/RJ

Objective: To quantify and to compare the hospitalizations sensible to primary care (HSPC) with the brute rate of hospitalizations analyzing its frequency with the family health program (FHP) in Petrópolis/RJ. Methods: After analyzing the national health system data, we extracted the rate of HSPC between 1999-2013. Then we have established the ratio of the hospitalizations and city residents multiplied by a thousand. The Pearson correlation coefficient was applied to obtain the variables correlation. Results: The data presented a reduction of 54.4% in the number of HSPC for the investigated period. Total hospitalizations related to primary care conditions went from 19.9% to 16.5%. The rate of HSPC decreased as the coverage of the FHP increased its coverage. Conclusion: The changes observed are significant and stimulate further investigations regarding the FHP strategy and its potential as an effective way of reducing the HSPC in other regions.

Objetivo: Quantificar as internações por condições sensíveis à atenção primária (ICSAP), comparando-as com a taxa bruta de internações e analisar sua frequência junto à cobertura do Programa Saúde da Família (PSF) em Petrópolis/RJ. Métodos: Após consulta no SIH-SUS, obteve-se a taxa bruta de ICSAP entre 1999-2013. Foi estabelecida a razão entre a soma destas internações e o número de residentes no município, multiplicado por mil. O coeficiente de correlação de Pearson foi utilizado para a análise de correlação entre as variáveis. Resultados: Houve redução de 54,4% nas ICSAP no período estudado. Observamos uma redução das ICSAP sobre o total de internações de 19,9%, para 16,5%. A redução na taxa de ICSAP apresentou forte correlação com o aumento da cobertura do PSF. Conclusão: As mudanças ocorridas são significativas e estimulam o aprofundamento do estudo da eficácia das estratégias como o PSF sobre a redução das ICSAP em diferentes municípios.

Objetivo: Cuantificar hospitalizaciones por enfermedades sensibles a la atención primaria (HESAP), comparándolos con la tasa bruta de hospitalizaciones y analizar su frecuencia por la cobertura del Programa de Salud de la Familia (PSF) en Petrópolis/RJ. Métodos: Previa consulta al SIH-SUS, se obtuvo la tasa bruta de HESAP entre 1999-2013. Se estableció la relación de la suma de estas hospitalizaciones y el número de residentes multiplicado por mil. Se utilizó el coeficiente de correlación de Pearson para análisis de las variables. Resultados: Hubo una reducción del 54,4% en las HESAP. Se ha observado una reducción de la ESAP en el total de ingresos de 19,9% a 16,5%. La reducción de la tasa de HESAP mostró una fuerte correlación con el aumento de la cobertura del PSF. Conclusión: Los significativos resultados estimulan más estudios sobre la eficacia de las estrategias tales como el PSF en la reducción de HESAP en diferentes municipios.
