Effect of physical training in obese patients with low back pain: a systematic review / Efeito do treinamento físico em obesos com lombalgia: revisão sistemática / Efecto del entrenamiento físico en pacientes obesos con dolor de la región lumbar: revisión sistemática

ABSTRACT Objective: To understand the hypoalgesic effect of exercises in obese patients with low back pain. Methods: From the methodological point of view, this is a systematic review study supported by the PRISMA guidelines (2020). Only clinical trials with defined eligibility criteria were included and the methodological evaluation was carried out using the Risk of Bias 2.0 (RoB 2.0) tool. Results: Four clinical trials were found, which underwent an assessment of risk of bias and were mostly categorized as moderate risk of bias or with some concerns. Conclusions: Moderate-intensity interval training (MIIT), high-intensity interval training (HIIT), and total resistance or lumbar spine extension exercises were shown to be effective for pain control, quality of life, and functional performance in obese individuals. On the other hand, the exercises alone did not produce a decrease in body composition. Level of evidence I; Systematic review.

RESUMO Objetivo: Conhecer o efeito hipoalgésico dos exercícios em pessoas obesas com lombalgia. Métodos: Do ponto de vista metodológico, é um estudo de revisão sistemática amparado pelas diretrizes do PRISMA (2020). Foram incluídos apenas estudos clínicos com critérios de elegibilidade definidos e a avaliação metodológica foi realizada com a ferramenta Risk of Bias 2.0 (RoB 2.0). Resultados: Foram encontrados quatro estudos clínicos que passaram por avaliação de risco de viés, sendo a maior parte dos estudos categorizada como risco moderado de viés ou some concerns. Conclusões: Os exercícios do tipo moderate-intensity interval training (MIIT), high-intensity interval training (HIIT) e resistência total ou extensão de coluna lombar mostram eficácia no controle da dor, na qualidade de vida e no desempenho funcional de indivíduos obesos. Por outro lado, os exercícios de forma isolada não apresentaram diminuição da composição corporal. Nível de evidência I; Revisão sistemática.

Reproducibility of an endurance test for master swimmers

Abstract Aim: This study aimed to verify the reproducibility of an endurance test for master swimmers. Methods: Seventeen male swimmers, aged from 30 to 50 years (35.06 ± 5.36), weight (78.71 ± 13.06 kg), height (174.35 ± 0.07 cm), participated in this study. The participants underwent the Progressive Swim Test (PSwT), which corresponds to swimming progressively to exhaustion in a 25-meter pool, guided by the recording of sound signals indicating the swimming rhythm. We verified the following variables: heart rate before the test (BHR) and right after the end of the test (AHR), followed by the rate of perceived exertion (RPE) and a total of laps performed (SN - swimming number). For comparison between the three days of tests, the one-way repeated measures ANOVA with Tukey's Post-Hoc was performed. Relative reproducibility was performed by the r test and the intraclass correlation coefficient (ICC). Absolute reproducibility was determined using the coefficient of variation (CV) and the confidence interval (CI). Results: The results showed high reproducibility in (PSwT) in master swimmers in the analyzed variables of intergroup and intragroup with relative reproducibility of r > 0.60 and ICC > 0.70 and absolute reproducibility with CI 95% (lower −1.10 and upper 0.99) and CV < 10%. Most of the cases were within the limits of agreement of the Bland-Altman tests, all variables were considered a level of significance with (p <0.05). Conclusion: The Progressive Swim Test (PSwT) is a reproducible instrument in the assessment of endurance in master swimmers.

Influence of menopause on body fat induced by aerobic training

AIMS :to compare the influence of menopause on body fat, induced by a physical training program. METHODS: Twenty-one sedentary women, 10 postmenopausal (MN; 54.6 ± 5.1 years, 42.9 ± 4.1 % body fat) and 11 in the ovulatory state (OS; 35.1 ± 5.4 years, 44.1 ± 5.5 % body fat), performed a training program with aerobic exercise (12 weeks, five times / week, 60 minutes per session). Before and after this program, the following measurements were taken: sum of skin fold (∑D), body fat percentage (%F), waist-hip ratio (WHR) and abdominal circumference (AC). RESULTS: MN and OS significantly reduced ΣD (38.5 ± 25.1 mm and 27.7 ± 19.4 mm, respectively), but without differences between the groups. MN group women obtained relative reduction in the suprailiac fold, significantly greater than OS (25 ± 10 vs. 11.5 ± 12 mm), and also a greater reduction in the %F (13.5 ± 8% vs. 6.6 ± 6%). There were very slight reductions in WHR in both groups (0.009 ± 0.02 and 0.005 ± 0.03 in MN and OS, respectively), as well as AC (reduction of 3.5 ± 3 cm and 3.9 ± 2.9 cm for MN and OS), with no differences between groups. CONCLUSION: The postmenopausal women responded to a training program with a greater reduction of body fat, but in only one of four evaluated body composition variables.(AU)

Treinamento aeróbio não altera pressão arterial de mulheres menopausadas e com síndrome metabólica / Aerobic training does not alter blood pressure in menopausal women with metabolic syndrome

FUNDAMENTO: A Hipertensão arterial (HA) é uma condição tanto agravante quanto agravada pela Síndrome Metabólica (SM). A menopausa pode tornar o tratamento da hipertensão mais difícil porque é uma condição que favorece a piora nos componentes da SM. Embora existam evidências de que o treinamento com exercícios físicos reduza a pressão arterial, se as condições da menopausa e da SM afetam os benefícios induzidos pelo exercício é algo ainda não evidenciado. OBJETIVO: Comparar os efeitos do treinamento aeróbio na pressão arterial entre mulheres com SM não menopausadas e menopausadas. MÉTODOS: Foram recrutadas 44 mulheres divididas em quatro grupos experimentais: controle não menopausada (CNM: 39,5 ± 1,1 anos, n = 11); controle menopausada (CM: 54,9 ± 1,7 anos, n = 12); aeróbio não menopausada (ANM: 43,1 ± 2,1 anos, n = 11) e aeróbio menopausada (AM: 52,1 ± 1,6 anos, n = 10). Os grupos de exercício realizaram treinamento aeróbio durante três meses, cinco vezes por semana, com intensidade entre 60% e 70% da frequência cardíaca de reserva. A pressão arterial de repouso e a resposta pressórica clínica após 60 minutos de exercício foram medidas antes e após o período treinamento. O teste de ANOVA de dois fatores foi usado, considerando p < 0,05. RESULTADOS: O programa de treinamento resultou em redução da gordura abdominal, glicemia e melhora do VO2 máx. Em comparação aos valores pré-intervenção, Pressão Arterial Sistólica (PAS) e Pressão Arterial Diastólica (PAD) não se alteraram após o treinamento nos grupos CNM, CM, ANM e AM (p > 0,05). CONCLUSÃO: Três meses de treinamento aeróbio melhora componentes da SM, mas não altera a pressão arterial de repouso, nem a resposta pressórica aguda após uma sessão de exercício aeróbio em mulheres com SM.

BACKGROUND: Arterial Hypertension (AH) is an aggravating condition for Metabolic Syndrome (MS), as well as being aggravated by it. Menopause can make hypertension treatment more difficult, as it favors the worsening of MS components. Although there is evidence that exercise training reduces blood pressure, whether menopause and SM affect the exercise-induced benefits is yet to be elucidated. OBJECTIVE: To compare the effects of aerobic training on blood pressure in non-menopausal and menopausal women with MS METHODS: A total of 44 women were recruited and divided into four groups: non-menopausal control (NMC: 39.5 ± 3.6 years, n = 11); menopausal control (MC: 54.9 ± 5.9 years, n = 12), non-menopausal aerobics (NMA: 43.1 ± 6.8 years, n = 11) and menopausal aerobics (MA: 52.1 ± 5 years, n = 10). The exercise groups performed aerobic training for three months, five times a week, at an intensity between 60% and 70% of heart rate reserve. The resting blood pressure and blood pressure response after 60 minutes of exercise were measured before and after the training period. The two-way ANOVA test was used, considering a p value < 0.05. RESULTS: The training program resulted in a decrease in abdominal fat, blood glucose and improved VO2 max. Compared to pre-intervention values, Systolic Blood Pressure (SBP) and Diastolic Blood Pressure (DBP) did not change after training in NMC, MC, MA and NMA groups (p > 0.05). CONCLUSION: Three months of aerobic training improved MS components, but did not alter resting blood pressure or the BP response after an acute exercise session in women with MS.
