Impact of deep water running in interval training (DWR-IT) on body composition, functional capacity, and quality of life in overweight adults: study protocol for a randomized controlled trial.

BACKGROUND: Interval training in deep water running (DWR-IT) is a training method to improve cardiovascular fitness, functional health, and quality of life and to help control body weight. Its main advantages are the reduction of joint overload and a low risk of musculoskeletal injuries. The aim of the study is to investigate the influence of DWR-IT on functional capacity, body composition, and quality of life of overweight middle-aged adults. METHODS: This is a randomized controlled, two-arm, open, parallel clinical trial with overweight adults. Volunteers will be allocated to a water group (WG), which will be submitted to the intervention, or a control group, which will not be subjected to any kind of intervention. The evaluation will be composed of anamnesis, electrical bioimpedance, six-minute walk test (6MWT), questionnaire on the Impact of Weight on Quality of Life-lite (IWQOL-LITE), Pittsburgh Sleep Quality Index, Epworth Sleepiness Scale, chair stand test, arm curl test, and food frequency questionnaire. The DWR-IT will last for 12 weeks, systematically increasing the intensity and training volume. DISCUSSION: The objective of this clinical trial is to evaluate the effect of DWR-IT on overweight adults. The study is guided through practice based on scientific evidence for the use of training and aquatic rehabilitation. It is expected that after 12 weeks of aquatic intervention there will be a decrease in body fat by about 10%, evaluated by electrical bioimpedance, an increase of about 25% of cardiorespiratory endurance, evaluated by 6MWT, and an improvement of about 25% of physical function domains, self-esteem, distress in public places, and work, analyzed by IWQOL-LITE in the WG. TRIAL REGISTRATION: The study protocol was published in the Brazilian Registry of Clinical Trials (ReBEC) on June 16, 2016. Registration number: RBR-6dmh7d.

Deep Water Running na redução da gordura corporal e aumento da força muscular em mulheres obesas: estudo piloto / Deep water running on body fat reduction and increased muscle strength in obese women: pilot study

Introdução: DWR-IT é um método de treinamento que visa melhorar a capacidade funcional, aptidão física e qualidade de vida, além de contribuir para controle da obesidade. Objetivo: investigar a influência do DWR-IT na composição corporal, circunferência abdominal, qualidade de vida, capacidade funcional, força e resistência muscular em mulheres obesas de meia idade. Método: trata-se de um estudo piloto de ensaio clínico não controlado, do tipo antes e depois. Foi avaliada a circunferência abdominal, a composição corporal e aplicados 6MWT, CST, ACT e IWQOL-LITE pré e pós-intervenção em sete mulheres obesas de meia idade. O período da intervenção foi de 10 semanas com frequência de três dias por semanas. Resultados e Discussão: houve redução da circunferência abdominal (de 94,71 ± 8,32 cm para 88,43 ± 6,29cm) e da massa gorda (29,50 ± 4,35 kg para 26,47 ± 4,85 kg),aumento da força e resistência muscular dos membros superiores (de 12,86 ±3,44 para 22,71 ±5,71 repetições) e inferiores (de10, 43 ± 2,30 para 14,14±2,67 repetições) e melhora nos domíniosfunção física (de 38,0; 37,0 - 45,0 para 47,00; 46,0 -49,50) e autoestima (de 27,00; 26,50-27,50 para 30,00; 28,0-33,00) do questionário IWQOL-LITE. Conclusão: 10 semanas de DWR-IT foramefetivas em promover melhora da composição corporal, da força eresistência muscular, da função física, da autoestima e melhoras em relação ao sobrepeso e obesidade.

Introduction: DWR-IT is a training method that aims to improve functional capacity, physical fitness and quality of life, in addition to contribute to the control of obesity. Objective: the objective was to investigate the influence of DWR-IT on body composition, abdominal circumference, quality of life, functional capacity, strength and muscular endurance in obese middle-aged women. Methods: this is a pilot study of an uncontrolled clinical trial, before and after. Abdominal circumference, body composition, and the application of 6MWT, CST, ACT and IWQOL-LITE were evaluated before and after intervention in seven obese middle-aged women. The intervention period lasted 10 weeks with a frequency of three days per week. Results and Discussion: there was a reduction in abdominal circumference (94.71 ± 8.32 cm for 88.43 ± 6.29 cm) and fat mass (29.50 ± 4.35 kg for 26.47 ± 4.85 kg), increase of muscle strength and endurance of the upper limbs (from 12.86 ± 3.44 to 22.71 ± 5.71 repetitions) and lower limbs (from 10.43 ± 2.30 to 14.14 ± 2.67 repetitions) and improvement in the physical function domains (from 38.0; 37.0 - 45.0 to 47.00; 46.0 - 49.50) and self-esteem (from 27.00 to 26.50-27.50 for 30.00; 28.0-33.00) in the IWQOL-LITE questionnaire. Conclusion: ten weeks of DWR-IT were effective to promote the improvement of body composition, strength and muscular endurance, physical function and self-esteem, and the improvement in overweight and obesity.

Effect of aquatic physical therapy on pain perception, functional capacity and quality of life in older people with knee osteoarthritis: study protocol for a randomized controlled trial.

BACKGROUND: Aquatic therapy promotes short-term benefits for patients with knee osteoarthritis (OA), and it may be the first therapeutic option for this pathological condition. The objective of this study was to investigate the effects of an aquatic therapy program on pain intensity, functional ability, and quality of life in older people with knee OA. METHODS/DESIGN: This is a parallel, two-arm, open, randomized controlled clinical trial with older people with knee OA. Volunteers will be allocated to an aquatic intervention group (WG), subjected to the intervention, or to a control group, not be subjected to any kind of intervention. Data collection pre- and postintervention will be composed of the evaluation of the perception of pain by visual analogue scale with application of nociceptive stimuli in four anatomical points of the knee, functional fitness tests, and application of the World Health Organization Quality of Life Scale abbreviated version and Western Ontario and McMaster Universities Osteoarthritis Index. The program will last 12 weeks, consisting of aerobic and functional exercises in the form of circuit training. DISCUSSION: The objective of this clinical trial is to evaluate the effect of aquatic therapy in elderly patients with knee OA. The study is guided by practice-based scientific evidence for the use of aquatic rehabilitation exercises. It is expected that the WG volunteers will show reduced pain intensity, increased flexibility, and improved functional capacity and quality of life. It is believed that the desired results can be attributed to physical and physiological effects of immersion in warm water associated with the exercise protocol proposed. The data will be published after completion of the study. TRIAL REGISTRATION: Brazilian Registry of Clinical Trials (ReBEC) registration number: RBR-78h48d . Registered on 19 August 2015.
