A randomized controlled trial on the effects of combined aerobic-resistance exercise on muscle strength and fatigue, glycemic control and health-related quality of life of type 2 diabetes patients

Aim: to evaluate the effects of a 12-weeks combined aerobic-resistance exercise therapy on fatigue and isokinetic muscle strength, glycemic control and health-related quality of life (HRQoL) in moderately affected type 2 diabetes (T2DM) patients. Methods: a randomized controlled trial design was employed. Forty-three T2DM patients were assigned to an exercise group (n = 22), performing 3 weekly sessions of 60 minutes of combined aerobic-resistance exercise for 12-weeks; or a no exercise control group (n = 21). Both groups were evaluated at a baseline and after 12-weeks of exercise therapy for: 1) muscle strength and fatigue by isokinetic dynamometry; 2) plasma glycated hemoglobin A1C (HbA1C); and 3) HRQoL utilizing the SF-36 questionnaire. Results: the exercise therapy led to improvements in muscle fatigue in knee extensors (-55%) and increased muscle strength in knee flexors and extensors (+15 to +30%), while HbA1C decreased (-18%). In addition, the exercising patients showed sizeable improvements in HRQoL: physical function (+53%), vitality (+21%) and mental health (+40%). Conclusion: 12-weeks of combined aerobic-resistance exercise was highly effective to improve muscle strength and fatigue, glycemic control and several aspects of HRQoL in T2DM patients. These data encourage the use of aerobic and resistance exercise in the good clinical care of T2DM.

Crenças, atitudes e comportamentos de saúde e de risco de adictos em comunidades terapêuticas

Os comportamentos de saúde e de risco são comuns em toxicodependentes. Este trabalho foi conduzido no âmbito da análise descritiva da amostra, nomeadamente, caracterização sócio-demográfica e variáveis cognitivas, seguindo-se um segundo objectivo que consistiu na descrição dos comportamentos, crenças e atitudes face à saúde que os adictos apresentam. A amostra é constituída por 75 sujeitos, do sexo masculino, com uma média de idade de 34,07 anos. A metodologia utilizada caracteriza o estudo de quantitativo-correlacionai, uma vez que se pretende efectuar a descrição das características da amostra e os comportamentos de saúde e de risco que apresentam. Os resultados revelam que os adictos apresentam comportamentos de risco, logo, são menores os comportamentos de saúde adoptados durante os consumos. É necessário intervir nas várias áreas de saúde do adicto, nomeadamente, nas práticas sexuais, na prevenção de doenças, nos cuidados alimentares, na conduta rodoviária e na preocupação com o exercício físico-desportivo. /ABSTRACT: Health behaviors and risk factors are common in drug addicts. This work was conducted under the descriptive analysis, including socio-demographic and cognitive variables, followed by a second objective was to describe the altitudes, beliefs and altitudes towards health that addicts have. The sample consists of 75 subjects were mala, with a mean age of 34.07 years. The methodology characterizes the quantitative and correlational study, since we intend to perform the description of sample characteristics and health behaviors and risk they present. The results show that addicts exhibit risky behavior, so they are smaller health behaviors adopted during the intake. lt is necessary to intervene in several areas of health of the addict, including sexual practices, disease prevention, care food, conduct road and the concern that physical exercise I sports.

Impacto da prática de exercício físico em adolescentes: bem-estar, autoestima e rendimento escolar

O presente estudo partiu de uma amostra de 472 estudantes, do 7º ao 9º ano de três escolas e duas entidades desportivas de Évora, e seis escolas de Lisboa. Procurou-se compreender qual o impacto que a prática de exercício físico tem na adolescência ao nível do bem-estar, autoestima e rendimento escolar através da aplicação da EBEPA e da Escala de Autoestima Global de Rosenberg. Objetivou-se também perceberquais as atitudes dos/as jovens face à educação física e ao exercício físico, através da aplicação do QAAEF e QAEFFCE. Os resultados obtidos sugerem que a prática de exercício físico extracurricular potencia os níveis de bem-estar, autoestima e rendimento escolar dos/as adolescentes. Ao praticarem exercício físico para além do proporcionado pelas aulas de educação física, estes jovens apresentam atitudes mais positivas no que diz respeito ao gosto e importância atribuídos à disciplina e à prática de exercício físico. Os rapazes apresentam resultados mais elevados do que as raparigas, no que diz respeito ao bem-estar e autoestima; Impact of physical exercise in adolescents: well-being, self-esteem and school performance Abstract: This study came from a sample of 472 students, from the 7th to the 9th grade of three schools and two sports entities of Évora, and six schools of Lisbon. We tried to understand the impact that the practice of physical exercise has in adolescence in terms of well-being, self-esteem and school performance through the application of the EBEPA and the Rosenberg Self-esteem Scale. The goal was also to understand the attitudes of young people in the face of physical education and physical exercise, through the application of QAAEF and QAEFFCE. The results suggest that the practice of extracurricular physical exercise increases levels of well-being, self-esteem and academic achievement of adolescents. By practice physical exercise,not counting physical education classes, these young people exhibit more positive attitudes giving more credit to the discipline and practice of physical exercise. This study confirmed that the boys have higher results than girls, with regard to the well-being and self-esteem.

Increased physical activity and fitness above the 50th percentile prevents the institutionalization of elderly people: a cross-sectional pilot study.

Introduction Institutionalization in a nursing home restricts autonomy, most notably free will, free choice, and free action. Decreased physical activity and fitness are predictive of disability and dependence (Rikli & Jones, 2013; Tak, Kuiper, Chorus, & Hopman-Rock, 2014); however little is known about the impact of these factors on institutionalization. Thus, this study aimed to analyze the impact of physical activity and fitness and on the risk of elderly people without cognitive impairment become institutionalized. Methods This cross-sectional study involved 195 non-institutionalized (80.14.4yrs) and 186 institutionalized (83.85.2yrs) participants. Cognitive impairment was assessed using Mini-Mental State Examination, physical activity was assessed using the International Physical Activity Questionnaire, and measures of physical fitness were determined by the Senior Fitness Test. Results: Multivariate binary logistic analysis selected 4 main predictors of institutionalization in both genders. The likelihood of becoming institutionalized increased by +18.6% for each additional year of age, while it decreased by -24.8% by each fewer kg/m2 in BMI, by -0.9% for each additional meter performed in the aerobic endurance test and by -2.0% for each additional 100MET-min/wk of physical activity expenditure (p<0.05). Values ≤50th percentile (age ≥81yrs, BMI≥26.7kg/m2, aerobic endurance ≤367.6m, and physical activity ≤693MET-min/wk) were computed using Receiver Operating Characteristics analysis as cut-offs discriminating institutionalized from non-institutionalized elderly people. Conclusion The performance of physical activity, allied to an improvement in physical fitness (mainly BMI and aerobic endurance) may prevent the institutionalization of elderly people without cognitive impairment only if they are above the 50th percentile; the following is highly recommend: expending ≥693MET-min/wk on physical activity, being ≤26.7kg/m2 on BMI, and being able to walk ≥367.6m in the aerobic endurance test, especially above the age of 80 years. The discovery of this trigger justifies the development of physical activity programs targeting the pointed cut-offs in old, and very old people. References Rikli, R., & Jones, C. (2013).
