Filter by:The objectives of this study are to examine the usability and efficacy, for diverse older adults, of a new tablet-based dynamic system: the Fittle Senior System (FSS) that will provide: (1) personalized behavior-change programs for improved diet and increased physical activity and (2) online social interaction and support from small teams pursuing similar goals. The proposed study involves a two group randomized trial where participants will be randomized to the Fittle Senior System or to a paper-based psycho-educational control condition following a baseline assessment. The duration of the intervention phase will involve an active 12-week intervention phase followed by a 12-week maintenance phase. We will recruit and randomize 180 community dwelling adults aged 65+ years, who live alone and are at risk for social isolation. Participants will be assessed at baseline, 3 months post active intervention and 3 months post maintenance (6 months following active intervention) on measures of health and health behaviors, and indices of social support.
This study evaluates the effects of physical exercise through active videogame in the microcirculation, macrocirculation, cardiorespiratory function and physical fitness in overweight adolescents. For that, they will be randomized into two groups, one being a control group and the other intervention group. The randomization will be made by school. The intervention group will perform the physical exercise through the active video game, three times a week, for 50 minutes, during 8 weeks. Reassessments will be performed before and after the intervention to evaluate the outcome variables.
Background: Evaluating the use of a novel motorized ankle prosthesis during walking and under dual task circumstances is an important step in product development. Objective: To iteratively evaluate the effectiveness of a novel bionic foot, the Ankle Mimicking Prosthetic device 4+ (or AMPfoot 4+), during walking. Study design: Case study (crossover) research design. Methods: One male subject will conduct a baseline experimental trial with the current prosthetic device and several experimental trials with the AMPfoot 4+ to evaluate the effectiveness of the novel device and investigate the adaptation period. Prior to baseline experiments, a familiarization trial will be performed to determine intra-subject variability of the dual task. An experimental trial consists of 2 walking tasks, i.e. the 6-minute walk test (6MWT) and the 10-meter walk test. The 6MWT will be combined with a cognitive task, i.e. backwards counting, to create dual task circumstances. The outcome measurements for the dual task are the distance covered and the walking speed, heart rate (HR) (Polar), rating of perceived exertion (RPE), VO2 (Cosmed K5), electro-encephalography (EEG), electro-myography (EMG), electro-cardiography (ECG), electrodermal activity (/skin conductance),accuracy and total duration of the cognitive task, BodyMedia (physical activity) and the visual analogue scale (VAS) for fatigue and comfort. A 10-meter walk test will be evaluated on duration. Expected findings: In a first phase the novel device will probably reduce walking and cognitive performance, whereas fine-tuning the mechatronics (after several retests) should improve walking and cognitive performance during walking.
Elderly in residential care spend 97% of their time sedentary. Moreover, exercise therapy often takes place in a poorly stimulating environment which is less motivational for the elderly to undertake regularly. Exercise is however necessary to preserve their physical capabilities and to limit their care dependence. The aim of this study is to investigate the most motivating and stimulating exercise modality for prefrail and frail elderly in nursing homes with which they can reach sufficient training volume. To study this, elderly will exercise in 3 different ways on an ergometer or motomed (according to their physical capabilities): 1) in an environment without other visual stimuli 2) in front of a television with National Geographic images 3) with the interactive software program MemoRide with which participants can exercise in real life on a virtual manner. MemoRide (Activ84Health) uses Google Street View images. The starting point is a connection between an exercise bike and a tablet with a pedalling sensor. This way, pedal frequency is sent to the tablet and as a result, images continue when pedalling. The forth modality is the control modality, in which participants are instructed to rest (supine) during 30 minutes. Based on objective training parameters and metabolic parameters e.g. glucose, insulin, brain-derived neurotrophic factor (BDNF) and lactate, (via a blood sample with a venous catheter) the training modality which offers the best training results will be studied. Secondly, also subject experiences (motivation and emotions) will be evaluated by using questionnaires and observation scales.
Recent drug improvement (e.g. abiraterone or enzalutamide) for castration resistant prostate cancer (CRPC) patients has improved survival. As treatment strategies improve and patients live longer, patients must cope with their treatment-induced adverse effects. Improving levels of physical activity (PA) and less amounts of sitting time (e.g. sedentary behavior, SB) could have a positive impact on patient's health, non-cancer mortality, and quality of life and potentially improve survival. The role of PA has not yet been examined in CRPC patients, which is a clear unmet need. No specific PA guidelines exist for CRPC patients, but specific guidelines are warranted because of advanced disease stage, reduced performance score and comorbidity. It is to be expected that the PA level of CRPC patients is lower compared to non-CRPC patients receiving androgen deprivation therapy (ADT). This study aims to determine the optimal starting physical therapy prescription in CRPC patients receiving second line hormone treatment.
Body-weight based interval training (IT) performed 3 times per week will lead to reductions in abdominal adiposity and reduce overall body fat percentage in overweight and obese sedentary adults more effectively than moderate intensity continuous training (MICT). Body-weight interval training will improve exercise capacity (peak VO2) in overweight/obese adults.
The VFB Ecosystem capitalizes on digital technologies' ability to connect parents and children, allowing parents to actively support their child's physical activity, even when parents cannot be present. The VFB is a kiosk-based system that houses a virtual dog programmed to allow children to set self-determined physical activity goals. The children wear Fitbits while performing physical activity. Using the unique data embedded in the Fitbit, the kiosk is able to detect each individual child and automatically connect him or her to a unique, personalized virtual dog. Physical activity data is transmitted automatically from the Fitbit to the kiosk when the child approaches, and the virtual dog provides accurate evaluations of whether the child met the self-determined physical activity goal, offering words of encouragement and physical activity support. The virtual pet functions as a personalized fitness buddy to encourage children to set and meet physical activity goals, promote physical activity self-efficacy, and foster mutually supportive relationships among children, parents, and the virtual pet. This will be particularly helpful for children who receive insufficient amounts of social support in their current environment. Concurrently, the kiosk sends a text message to parents on the child's physical activity progress. Parents are then able to send words of encouragement and communicate with their children via the kiosk, using the text messaging feature of their mobile phones. Thus, even when the parent is not with the child, the virtual pet is designed to serve as a coordinating focus for facilitating parent-child communication. Parents will also receive text messages from the kiosk with a security code to access a website that provides detailed records of the child's physical activity over time.
This study explores the levels of daily physical activity and sedentary behaviour in Maastricht University's undergraduate first year students. Furthermore, this study explores the correlations between the students' demographical background information with their levels of physical activity and sedentary behaviour.
The main aim of this study is to describe differences in development of health and motor performance over time in relation to type of school and other background variables.
Normal aging is associated with balance, mobility and executive functions decline that increase fall risk and influence Activity of Daily Living (ADL) and Instrumental ADL (IADL) functions such as safe road-crossing, planning and organizing everyday activities. Changes in cerebellar functional plasticity may mediate between the decline in balance, mobility and executive functions during elderly. Fortunately, mounting evidence suggests that physical activity is beneficial for decreasing aging effects and optimize brain structure and function. According to the dynamic systems theory, the environment in which the physical activity occurs influences the results of the activity. We propose an aquatic physical intervention program as a tool to decrease aging effects that in turn might lower fall risk, increase safety of road-crossing and improve planning and organizing everyday activities among community-dwelling older individuals.
