Filter by:Nutritional interventions witch stimulate the rate of muscle protein synthesis are relevant for the development of therapeutic strategies aimed at attenuating the loss of mass and muscle strength related to aging (sarcopenia). To aim of the study is to investigate the effect of protein supplementation on body composition, muscle activity, muscle strength and plasma concentration of inflammatory biomarkers of elderly with type II diabetic, submitted to 12 weeks of resistance training. This is an interventional, controlled, randomized, double-blind study. The population of the present study will be composed of 40 men with type 2 diabetes aged between 70 and 74 years, whose body mass index (BMI) should be between 22 and 32 kg / m2. It will be composed of patients from the Diabetes Outpatient Clinic of the Endocrinology Department at the Medical School of the University of São Paulo. Elderly subjects will be randomized into two groups (n = 20) who will undergo resistance training for 12 weeks, twice a week, and receive protein or placebo supplementation. Exercises will be performed for the large muscle groups: pectoral press, paddling, leg-press, extensor chair, gastrocnemius plantar flexions and abdominal crunches. Protein supplementation will be performed immediately after strength training by ingestion of 20 g of whey protein diluted in water. Also, immediately after training the placebo group will receive 20 g of maltodextrin diluted in water. All participants will be instructed to ingest 1.0 to 1.2 g of protein / kg of body weight per day. 24-hour food recall and food frequency questionnaires will be performed throughout the study. The following evaluations (before and after 12 weeks training) will be applied: Anthropometric: body mass, height, BMI and hip waist ratio. Functional evaluation through isokinetic dynamometry of knee extensors and flexors and a maximal repetition (1RM). Evaluation of body composition through Bioimpedance balance. Evaluation of food intake will be obtained by means of a 24-hour recall and food frequency questionnaire. All the evaluations will performed after 6 months. The training sessions will have a frequency of twice a week for 12 weeks. Eight exercises will be performed for the main muscle groups. In each exercise, 3 sets will be performed between 8 and 12 repetitions. The intensity should be between 7 - 8 and will be monitored according to Subjective Effort Perception using a scale of 0 to 10.
Background: - Diesel fuel is the most commonly used fuel to power cars and trucks worldwide. However, diesel exhaust fumes can have harmful effects on the body. Researchers are interested in studying how diesel exhaust exposure can affect lung health. To study these effects, researchers will look at employees of a diesel truck engine testing facility in China. Some workers at this facility are exposed to high levels of diesel exhaust. This study will compare tests and monitoring information from a group of highly exposed workers and a similar group of unexposed comparable controls. Objectives: - To study the effects of diesel exhaust on lung health. Eligibility: - Participants will be drawn from a diesel truck engine testing facility and other workplaces in China. - Individuals at least 18 years of age who work in workshops with diesel fuel. - Individuals at least 18 years of age who work in workshops that do not use diesel fuel. Design: - Depending on what type of factory study subjects work in, participants will wear personal air pumps and small badges on their clothing on one or more days. This equipment will measure particles, chemicals, and other compounds in the air. This information plus other information collected in the study including workplace practices will be used to estimate exposure to diesel exhaust among study subjects. - Participants will provide a number of study samples. These samples include blood, urine, and sputum. To collect other samples, participants will also have a mouth rinse, cheek cell scrapes, and nasal cell scrapes. They will also have a physical exam. - Treatment will not be provided as part of this study. Participants will receive financial compensation for participation in the study.
