Comparative effects of high intensity interval training versus moderate intensity continuous training on quality of life in patients with heart failure: Study protocol for a randomized controlled trial

© 2015 The Authors. Published by Elsevier B.V. Purpose To compare the effect of high intensity interval training (HIIT) and moderate intensity continuous training (MICT) on physical fitness and quality of life (QoL) in patients with chronic heart failure (CHF). Methods Twenty-two male CHF patients (LVEF < 45%, mean age 53.8 ± 8 yr) were studied before and after 12 weeks of supervised aerobic training for 60 min, three times a week. Patients were randomly (1:1) to MICT (n = 10) and HIIT (n = 12). Both training programs involved treadmill exercise. The group MICT at 75% of peak heart rate (HR) and HIIT at ≈ 95% of peak HR. Outcome measurements included an assessment of QoL (Minnesota Living with Heart Failure Questionnaire (MLHFQ) and SF-36), measurements of 6-min walk test (6MWT) and peak oxygen consumption (VO2 peak). Results Exercise was associated with a significant increased of 6MWT in 19.4% and 23.1% from MCIT and HIIT, respectively (p < 0.001), but not between-group differences. It was observed an improvement in VO2 peak by 11.2% in the HIIT group and 8.3% in the MCIT group, with between-group differences (p < 0.01). Quality of life improved significantly and in all domains in both groups (p-value time-effect). All patients showed significant improvements in all domains from baseline, it was observed in both groups (p < 0.05), with between-group differences for functional capacity (SF-36). No changes were observed in pain (SF-36) for both groups. Conclusion Both training programs were equally effective in improving QoL and functional capacity in CHF patients.

Cirurgia bariátrica: repercussões na vida laboral do obeso

Pesquisa descritivo-exploratória que objetivou conhecer as repercussões da cirurgia bariátrica na vida laboral do obeso grau III, com pacientes submetidos à gastroplastia em Y de Roux. A coleta de dados foi realizada de junho a julho de 2011, por meio de entrevista individual, originando três Discursos do Sujeito Coletivo: “Mais disposição para o trabalho”, “A vida sem comorbidades” e “Outras repercussões da cirurgia bariátrica”. Foram incluídos 30 pacientes com média de idade 44±12 anos, sendo 24 (80%) do sexo feminino, 19 (63%) que trabalhavam, 10 (34%) que não trabalhavam, um (3,3%) estudante, 23 (96%) hipertensos e oito (33%) com diagnóstico de Diabetes Mellitus. Constatou-se, também, que 13 (43%) tinham dificuldades no aspecto físico e que 21 (70%) as tinham no aspecto emocional. A cirurgia bariátrica repercutiu favoravelmente na vida laboral do obeso, uma vez que houve redução das comorbidades e das dificuldades físicas e emocionais, favorecendo a reinserção social e profissional do indivíduo
