Land- and water-based aerobic exercise program on health-related outcomes in breast cancer survivors (WaterMama): study protocol for a randomized clinical trial.

BACKGROUND: Breast cancer is a prevalent form of cancer among women worldwide, often accompanied by physical and psychological side effects due to the disease and the treatment's aggressiveness. Regular physical exercise has emerged as a non-pharmacological approach to improve the quality of life of breast cancer survivors. We herein report the protocol of the WaterMama Study, which aims to evaluate the effects of land- or water-based aerobic exercise programs, compared to a health education program, on cancer-related fatigue and other health-related outcomes in breast cancer survivors. METHODS: The WaterMama trial is a randomized, single-blinded, three-arm, parallel, superiority trial. We aim to recruit 48 women ≥ 18 years of age who have completed primary treatment for stage I-III breast cancer. Participants are randomly allocated in a 1:1:1 ratio to 12-week interventions of aerobic exercise training programs either in the aquatic or land environment (two weekly 45-min sessions) plus health education (a weekly 45-min session), or an active-control group receiving health education alone (a weekly 45-min session). The primary outcome is cancer-related fatigue, and the secondary outcomes include cardiorespiratory fitness, muscular performance, muscle morphology, functional capacity, mental health, cognitive function, pain, and quality of life. Outcomes assessments are conducted before and after the 12-week intervention period. The analysis plan will employ an intention-to-treat approach and per protocol criteria. DISCUSSION: Our conceptual hypothesis is that both aerobic exercise programs will positively impact primary and secondary outcomes compared to the health education group alone. Additionally, due to its multi-component nature, we expect the aquatic exercise program promote more significant effects than the land exercise program on cancer-related fatigue, muscular outcomes, and pain. TRIAL REGISTRATION: The study was prospectively registered at ClinicalTrials.gov NCT05520515. Registered on August 26, 2022. https://clinicaltrials.gov/ct2/show/NCT05520515.

Impact of Resistance Training Volume on Physical and Perceptual Outcomes of Breast Cancer Survivors Submitted to a Combined Training Program: A Randomized, Single-Blinded Study.

BACKGROUND: To determine the effect of resistance training volume on physical and perceptual outcomes of breast cancer survivors submitted to a combined training program. DESIGN: Randomized single-blinded study. METHODS: Nineteen breast cancer survivor women were randomized to a single-set (SS) or a multiple-set (MS) group. Both groups completed an 8-week combined training intervention in which the SS and MS groups performed 1 and 3 sets per resistance exercise, respectively. The following outcomes were assessed preintervention and postintervention: maximal knee extension dynamic strength (1-repetition maximum), quadriceps muscle thickness, peak oxygen uptake, time to exhaustion, cancer-related fatigue, and quality of life. RESULTS: Both interventions increased knee extension 1-repetition maximum (SS: 29.8% [37.5%]; MS: 19.3% [11.8%]), quadriceps muscle thickness (9.4% [4.1%]; 8.9% [5.9%]), and quality of life (4.3% [6.3%]; 7.9% [9.0%]), with no difference between the groups. However, only MS improved cancer-related fatigue (-2.1% [1.7%]) and time to exhaustion (21.3% [14.9%]), whereas peak oxygen uptake remained unchanged in both groups. CONCLUSIONS: Cancer-related fatigue and time to exhaustion, improved only in the MS group after the intervention. On the other hand, similar knee extension 1-repetition maximum, quadriceps muscle thickness, and quality of life improvements were observed in breast cancer survivors irrespective of the resistance training volume performed.

Exercício físico remoto e fadiga em sobreviventes do câncer de mama: uma intervenção em tempos da COVID-19 / Physical exercise using telehealth and fatigue in breast cancer survivors: an intervention in the days of COVID-19

O objetivo do presente estudo foi verificar os efeitos de um programa de exercício físico supervisionado remotamente sobre a percepção de fadiga de sobreviventes do câncer de mama durante a pandemia da COVID-19. Participaram do estudo dez mulheres (56,30 ± 14,00 anos) fisicamente ativas, participantes de um programa de extensão universitário e que foram diagnosticadas com câncer de mama entre os estágios I-III (5,65 ± 2,19 anos de diagnóstico). O programa de exercício físico foi realizado de forma supervisionada por meio de chamada de vídeo durante 12 semanas, com duas sessões semanais de 30 minutos, em dias não consecutivos. Os treinos foram compostos por exercícios de mobilidade articular, de força, aeróbios e de equilíbrio, sendo modificados a cada três semanas. A percepção de fadiga relacionada ao câncer foi medida pela Piper Fatigue Scale por meio de chamada telefônica, antes e após as 12 semanas de intervenção. Os dados foram analisados utilizando o teste não-paramétrico Wilcoxon. Os resultados demonstraram valores de todos os domínios da fadiga relacionada ao câncer (fadiga total: p = 0,463; comportamental: p = 0,655; afetiva: p = 0,593; sensorial: p = 0,223; cognitiva: p = 0,141) estatisticamente semelhantes entre os momentos pré e pós intervenção. Conclui-se que, após 12 semanas de um programa de exercício físico supervisionado remotamente por chamada de vídeo, durante o distanciamento social devido a pandemia da CO-VID-19, a percepção de fadiga de mulheres sobreviventes do câncer de mama permaneceu estável

The purpose of the present study was to verify the effects of physical exercise using telehealth on the cancer-related fatigue in breast cancer survivors during the COVID-19 pandemic. Ten physically active women (56.30 ± 14.00 years) participating in a university extension program and diagnosed with breast cancer between stages I-III (5.65 ± 2.19 years of diagnosis) were included in the study. Physical exercise program was carried out with supervision through video call for 12 weeks with two 30-minutes sessions per week on non-consecutive days. The training sessions consisted of joint mobility, strength, aerobic and balance exercises, and were modified every three weeks. The cancer-related fatigue was measured pre and post 12 weeks of intervention by the Piper Fatigue Scale through a telephone call. The data were analyzed using the Wilcoxon non-parametric test. The results showed values of all domains of cancer-related fatigue (total fatigue: p = 0.463; behavioral: p = 0.655; affective: p = 0.593; sensory: p = 0.223; cognitive/mood: p = 0.141) statistically similar between pre and post intervention time points. It is concluded that after 12 weeks of a supervised physical exercise program using telehealth, during social distance due to the COVID-19 pandemic, the perception of fatigue in breast cancer survivors remained stable

Frequency of musculoskeletal symptoms among police officers: systematic review / Frequência de sintomas musculoesqueléticos entre policiais: revisão sistemática

ABSTRACT BACKGROUND AND OBJECTIVES: Musculoskeletal symptoms are considered one of the major health problems among police officers. However, no study has synthesized the frequency of these disorders in different parts of the body in this population. The study aimed to describe the frequency of musculoskeletal symptoms in different body regions of the police officers. CONTENTS: A search was conducted in the electronic databases Pubmed/Medline, Web of Science, LILACS, and Scielo, as well as a manual search in the references of the articles. Ten of the 4025 possible studies found were included, which reported different types of musculoskeletal symptoms frequency in different body regions and periods. The frequency of musculoskeletal symptoms within 12 months ranged from 42-52% for the lower back, 34-43% for the knees, 7-32% for the shoulders, 7-27% for the wrists/hands/fingers, 29-42% for the neck, 18-28% for ankle/foot, 8-10% for elbow, 22-45% for upper back and 12-18% for hip/thigh. CONCLUSION: The frequency of musculoskeletal symptoms in police officers was high, especially in the lumbar, dorsal, knee, neck, and shoulder regions. Preventive measures such as physical activity and ergonomic adaptations to reduce these symptoms in this population are necessary.

RESUMO JUSTIFICATIVA E OBJETIVOS: Os sintomas musculoesqueléticos são considerados um dos maiores problemas de saúde entre policiais, porém nenhum estudo sintetizou a frequência desses distúrbios em diferentes partes do corpo nessa população. O objetivo deste estudo foi descrever a frequência dos sintomas musculoesqueléticos nas diferentes regiões do corpo de policiais. CONTEÚDO: Foi conduzida uma busca nas bases eletrônicas Pubmed/Medline, Web of Science, LILACS e Scielo, bem como busca manual nas referências dos artigos. Foram incluídos 10 dos 4.025 possíveis estudos encontrados, os quais reportaram diversos tipos de frequência de sintomas musculoesqueléticos em diferentes regiões do corpo e períodos. A frequência de sintomas musculoesqueléticos no período de 12 meses variou entre 42-52% para região lombar, 34-43% para joelhos, 7-32% para ombros, 7-27% para punhos/mãos/dedos, 29-42% para pescoço, 18-28% para tornozelo/pé, 8-10% para cotovelo, 22-45% para parte superior das costas e 12-18% para quadril/coxa. CONCLUSÃO: A frequência de sintomas musculoesqueléticos em policiais foi alta, principalmente nas regiões lombares, dorsais, joelhos, pescoço e ombros. Devem ser realizadas medidas preventivas, tais como atividades físicas e adaptações ergonômicas, visando a redução desses sintomas nessa população.
