Water-based continuous and interval training in older women: Cardiorespiratory and neuromuscular outcomes (WATER study)

The purpose of this study was to investigate the effects of two water-based aerobic programs on cardiorespiratory and neuromuscular outcomes in older women. Forty-one women (60 to 75 years old) volunteered to participate in the study. Participants were randomized into a water-based continuous (CTG; n = 21; 63.9 ± 2.5 years) or an interval (ITG; n = 20; 64.8 ± 3.6 years) aerobic training group. Both training programs were performed for 12 weeks (45-min sessions twice a week), with exercise intensity based on rating of perceived exertion (Borg's RPE 6-20 Scale). Pre and post training assessments of cardiorespiratory and neuromuscular outcomes were performed. Data analyses were conducted using Generalized Estimating Equations and Bonferroni post-hoc test (α = 0.05). After the intervention, the CTG and the ITG displayed similar improvements in time to exhaustion (8% vs. 11%), peak oxygen uptake (9% vs. 7%), maximal dynamic knee extension strength (5% vs. 6%), dynamic muscular endurance of knee extensors (10% vs. 11%), maximal vastus lateralis electromyographic signal amplitude (13% vs. 35%), as well as an increase in muscle thickness (5% vs. 6%) and decrease in muscle echo intensity (-2% vs. -3%) of the quadriceps femoris. In conclusion, older women benefited from water-based exercise training prescribed based on participants' RPE, with both the interval and the continuous training programs resulting in similar increases in the cardiorespiratory and neuromuscular parameters

Influence of aerobic and strength training in the gestational diabetes treatment : a systematic review

O diabetes mellitus gestacional (DMG) é uma complicação comum cuja prevalência tem crescido constantemente. Evidências sugerem que intervenções em gestantes com DMG podem reduzir a ocorrência de desfechos adversos. Apesar de o exercício físico ser bem aceito como uma terapia complementar no manejo do diabetes tipo 2 fora da gestação, no DMG ainda não se sabe qual a melhor prescrição para obter os melhores resultados. Portanto, este estudo teve como objetivo revisar as evidências científicas sobre o efeito de diferentes tipos de treinamento físico no tratamento do DMG. Foram consultadas as bases de dados, Scopus, Pubmed e Scielo. Foram excluídos os estudos de revisão sistemática, editoriais, cartas ao editor, relatos de caso, estudos laboratoriais e artigos que não avaliassem dos efeitos de intervenção através de exercício aeróbico ou de força, em mulheres diagnosticadas com DMG. Foram identificados 661 estudos e incluídos 6 na análise final. Foram encontrados estudos que utilizaram o treinamento físico como parte do tratamento do DMG, a maioria demonstrou efeito benéfico, como melhora do controle glicêmico e diminuição das necessidades de insulina. O tipo de exercício escolhido pela maioria dos pesquisadores foi o aeróbico, entretanto os estudos que utilizaram o exercício de força também demonstraram melhor controle glicêmico. Considerando os achados desses estudos, o treinamento físico tanto aeróbico como de força, apresentou efeitos benéficos para mulheres com DMG, uma vez que ajudou a controlar a glicemia e reduzir as necessidades de insulina.The gestational diabetes mellitus (GDM) is a common complication whose prevalence has steadily grown. Evidence suggests that interventions in pregnant women with GDM may reduce the occurrence of adverse outcomes. Although exercise is well accepted as a complementary therapy in type 2 diabetes in non-pregnant women, but is still unclear what is the best prescription for best results in the management of GDM. Therefore, this study aimed to review the scientific evidence on the effect of different types of exercise training in the treatment of GDM. Databases such as Scopus, Pubmed e Scielo were consulted. Systematic reviews, editorials, letters to the editor, case reports, laboratory studies and articles that do not evaluated the effects of intervention through aerobic or strength exercise in women diagnosed with GDM were excluded. 661 studies were first identified and 6 were included in the final analysis. Studies using exercise as part of GDM treatment demonstrated beneficial effects, such as improved glycemic control and decreased insulin requirements. The type of exercise chosen by most researchers was aerobic, however studies using strength exercise also demonstrated to improve glycemic control. The studies founded in the present systematic review, showed beneficial effects of aerobic and strength training for women with GDM, once helped to control blood sugar and to reduce insulin requirements

The effects of the Pilates method in the elderly: a systematic review

ABSTRACT Several studies show the benefits of including muscle strength and aerobic physical activity in the routine of elderly people. Among the various possibilities of physical activity, the Pilates method has become a popular modality in recent years, through a system of exercises enabling to work the whole body and that corrects posture and realigns the muscles, developing the body stability needed for a healthier life. The aim of this study was to review the current evidence on the effects of the practice of the Pilates method in the elderly. A systematic literature review was conducted in the following electronic databases: Pubmed, Scielo, Lilacs/Bireme, Scopus, Pedro and Isi of Knowledge, from descriptors pilates, elderly, old adults, aging. In the selection of studies the following inclusion criteria were used: original articles in English, Portuguese and Spanish languages. All selection and evaluation processes of the articles were performed by peers and the quality was verified by the Downs and Black scale. Twenty-one studies were included. The year of publication ranged from 2003 to 2014 and the size of the sample varied from 8 to 311 elderly subjects, aged at least 60 years old. The intervention period was from 4 weeks to 12 months of Pilates exercise practice. It was concluded that despite the studies pointing to physical and motor benefits of the Pilates method in the elderly, we cannot state whether or not the method is effective, in view of the poor methodological quality of the studies included in this review
