It is well established that physical activity reduces the physiological effects of ageing. Among them, the decrease of the autonomic nervous system activity (ANS) is associated with the increase of cardiovascular events and sleep disorders occurence. It has been shown that high intensity cycle training can enhance the ANS activity by 30% in people aged of 70 years old. However, such trainings were done by old athletes used to train at intensities that could not be handled by nursing home elderly. Thus, an adapted activity such as brisk walking shall be defined to make it practicable for the many in convalescent homes. The investigators hypothesize that long term brisk walking training could lead to reactivate ANS in people living in convalescent homes.
The study evaluates the effectiveness of the game-intervention in promotion of physical activity self-efficacy and physical activity behavior among early adolescents (10-13 year olds). Half of the study participants will receive the game-intervention and half of the study participants will receive a commercially available sport and fitness application for running, cycling and every-day training.
In this three-year project, investigators will target on sedentary middle-aged and older adults with cardiovascular risks, prescribe 24-week Tai Chi or aerobic exercises and examine: 1. Whether both exercises are effective to reduce cardiovascular risks, prevent leukoaraiosis and associated declines in physical and psychological functions at Week 12 and 24; 2. Will Tai Chi exercises be more effective on improving psychological health (cognition, psychological well-being, and exercise self-efficacy) than aerobic exercises at Week 12 and 24? If yes, are these effects mediated by specific brain structural and functional mechanisms? 3. Will aerobic exercises be more effective on improving physical health (motor functions, physical fitness, and heart rate variability) than Tai Chi exercises at Week 12 and 24? If yes, are these effects mediated by other specific brain structural and functional mechanisms? 4. After 12 and 24 weeks of Tai Chi and aerobic exercises, what are the relationships between reduction of cardiovascular risks and changes in brain structure and functions? An assessor-blind randomized controlled clinical trial will be used. Based on known effect size of Tai Chi exercises on cognitive function (please refer to CM03, pages 9-10), 120 sedentary middle-aged and older adults with cardiovascular risks will be recruited and randomly assigned to the Tai Chi, Aerobic, or Control (usual care) group. The Tai Chi and Aerobic groups will receive three one-hour exercise sessions weekly for 24 weeks, supervised for the first 12 weeks and unsupervised for the next 12 weeks. The Control group will maintain the original life style. Clinical measures of cardiovascular risks and blood markers, brain structures and functional images, psychological (cognitive, psychological well-being and exercise self-efficacy) and physical (motor functions, physical fitness, and heart rate variability) functions will be collected at baseline, Week 12, and Week 24 to compare differences among the three groups across the three time points. Investigators will also examine the interrelationships of changes in brain structural and functional organization with changes in other measures, in an effort to understand the neural mechanisms of exercise effects.
While people commonly understand that regular physical exercise conveys many health benefits, only 20% of U.S. adults take regular exercise and they have difficulty maintaining new healthy behaviors. The goal of this study is to use a planning intervention to help establish and maintain a daily step regimen in working midlife adults. The investigators will ask participants to plan when, where, and how to act on a daily walking goal in conjunction with a scheduling intervention to increase the chances that they will maintain this new regimen. The effectiveness of three different scheduling interventions will be compared.
The goal of this randomized controlled trial is to investigate the effects of a dance intervention on cardiovascular risk factors and functional capacity of older women, comparing dancing to a walking exercise intervention and to an active control condition (stretching). The participants will include women between 60 and 80 years old, with body mass index inferior to 35 Kg /m2. The main outcome of this study is the peak oxygen consumption (VO2peak). The secondary outcomes are cardiovascular risk associated factors (C-reactive protein, TNF-alpha, lipid profile, etc) and functional performance (muscle strength and power, balance, gate ability, etc). The experimental design will include 3 parts: 1) Pre-intervention assessments: medical evaluation, fasting blood exams, maximum exercise test, assessments of body composition, balance, gate ability, muscular strength and power. 2) Period of interventions: patients will be randomized to one of the three following groups: dance, walking or stretching. The duration of the interventions will be 8 weeks, including 3 sessions per week for dance and walking, and once a week for the stretching group. Each session will last 60 min. 3) Post-intervention assessments: the same protocols of testing as pre-intervention.
This study investigates the influence of acute exacerbation of chronic obstructive pulmonary disease (COPD) on retinal microcirculation, on functional status and also investigates the prognostic value of retinal vessel caliber assessment in terms of hospitalization and mortality during 2 years of follow-up.
Introduction. Multiple sclerosis (MS) is the most common neurological disease causing disability in young adults. Neurorehabilitation is a fundamental aspect in the treatment approach for MS, in which new technologies have gained popularity, especially the use of virtual reality (VR), thanks to the therapeutic possibilities offered for patients with MS presenting cognitive, sensitive and motor dysfunctions. Aim. To analyze and compare an occupational therapy intervention (OT) compared with OT + VR (OT+VR) on the manual dexterity of patients with MS. Material and methods. 26 patients will be recruited. The control group (n=8) will recieve 20 conventional OT sessions distributed in two sessions per week. The experimental group OT+VR (n=8) will recieve 20 sessions of VR interventions, twice weekly and lasting 30 minutes, consisting of VR games accessed via the online webpage motiongamingconsole.com, including Flip Out, Air Hockey, Partículas, Dunkit, Cuenta peces and Robo Maro, in addition to the conventional OT sessions. Pre and post-intervention assessments will be based on the Purdue Pegboard Test, the Jebsen Taylor Hand Function Test and the Grooved Pegboard Test.
This study aims to study differences in clinical and functional outcomes at 2 years based on hamstring graft size after single bundle anatomic ACL reconstruction using either 4-strand or 5-strand hamstring grafts. We also propose to study the characteristics of hamstring graft in our subset of patients in Asian population context.
This study will determine the effect of physical activity promotion based on Thai Physical Activity Guideline (TPAG) and break in workplace sitting on physical activity level, physical fitness, body compositions, cognitive functions and cardiometabolic biomarkers in office workers at Software Park Thailand under the Office of Science and Technology (NSTDA). There are two intervention including physical activity (PA) coaching based on TPAG and break in workplace sitting. The investigators will coach participants for promoting daily active life and participating to monthly exercise programs. The participants will be assign to break in sitting during daily work.
