Filter by:This is an intersectional and interdisciplinary screening program in Viborg Municipality, including 67 years old citizens. This observational study will estimate the cost-effectiveness of a combined screening program for the following conditions: Abdominal aortic aneurysm, peripheral arterial disease, carotid plaque, hypertension, arrhythmia, and type-2-diabetes. Furthermore, the incidence of the outlined conditions will be described and so will the result of the intervention initiated (secondary medical prophylaxis, smoking cessation, introduction to nutritionally deficient diet etc.)
Tendons are essential structures for transmitting muscle forces to skeletal structures. A stiffer tendon will transmit muscle force faster, and then allow faster movement. Moreover, tendons are a living tissue and respond to mechanical forces by changing their metabolism as well as their structural and mechanical properties. The aim of the present study is to answer essential questions remaining unanswered that are necessary in order to optimize physical activity with ageing in humans, and thus improve quality of life in elderly. The main questions are: What is the minimal training intensity leading to tendon adaptations? What is the time-course of tendon adaptations? Does the same loading protocol lead to similar tendon adaptations for different tendons (Achilles vs Patellar) and does the same training program lead to identical tendon adaptations with age (25yrs vs 75yrs)? To answer these questions, tendon architecture and mechanical properties will be investigated in humans of different age and applying different training intensities. The kinematic of the tendon adaptations due to these different training characteristics will also be investigated. The training protocol will be applied on plantar flexors and knee extensors. MRI and ultrasound techniques as well as the use of ankle and knee ergometers will allow the quantification of possible modifications in tendon architecture and mechanical properties (tendon stiffness and Young's Modulus). This will be assessed in vivo, using ultrasound images to assess tendon displacement during an incremental maximal contraction.
This study is a randomized clinical trial that has as objective to evaluate the effects of training with a vibratory platform on body composition, muscular strength functional capacity, flexibility and biochemical profile on elderly women. It will be done in the city of Santa Cruz do Sul, Rio Grande do Sul, with elderly women between the ages of 60 and 80 years-old, within the municipal limits and nearby areas selected randomly by a brown envelope in which a note will be stating if they belong to the control or vibratory platform group, in which the participant will be receiving whole body vibrations on the platform. The recruiting will be done by the institution through e-mail or by public call. Women will be evaluated through anamesis. On the evaluation, a questionaire will be applied, in order to evaluate if they don´t have counterindications for the vibratory platform. They will be evaluated in their general health, socio-economical status, and history of physical activity. Participants will have their doubts cleared about the study, and a written consent will be signed. Before the intervention with whole body vibrations, nutritional and physical activity aspects will be evaluated. The treatment period on the vibratory platform will be of 8 weeks, before and after it, anthropometrical, biochemical, strength, flexibility, palmar prehension strength, metabolic basal load, and functional capacity measurements will be taken. Before and after every session on the vibratory platform, heart rate, respiratory rate, arterial pressure, and peripheric oxygen saturation will be evaluated. The interventional procedure will be done with a vibratory platform (Power Plate®, model my7™, UK) with a frequency of 30 - 40 Hz, with low (2mm) or high (4mm) amplitude. Training will last 8 weeks with 3 sessions per week, lasting between 30 seconds and 1 minute of training, and 30 seconds to 1 minute of rest, with the subject positioned in orthosis with a knee flexion of 15° and a feet width distance of 20 cm. The frequency will be of 35 Hz and the amplitude of 2 mm. The study aims to contribute with reducing the body mass index and body fat percentage, to improve the lean mass, palmar prehension strength, muscular strength on the lower limbs and flexibility, also obtaining better biochemical profiles after the training period.
The goal of this research study is to collect clinical data, comprehensive geriatric assessment, risk factors, biological data and blood samples from inpatients aged 65 and older at the INRCA research hospitals (Italy). All data will be stored in a research bank and used to better clarify the mechanisms underlying the condition of "frailty" in aged patients. The database will be created on the INRCA server platform by establishing a safe HTTPS protocol.
