Filter by:This research was designed with partners to determine differences in temperature exposures in urban and rural communities in Alabama. The investigators hypothesized that significant differences in temperature exposure exist between urban and rural settings. Time spent outdoors has been previously positively associated with greater physical activity. Built environment components in urban versus rural environments and ambient temperatures experienced during the summer may pose barriers to time spent outdoors. Persons with Type II Diabetes Mellitus may find it more difficult to overcome temperature barriers due to reduced thermoregulation capacity. This analysis will result in a more precise picture of temperature exposure as well as behavioral factors that may mediate exposure.
Robotic devices may be used to help the gait and balance of individuals with Spinal Cord Injury (SCI). However, as such devices may allow individuals to engage in physical activity in an upright position, there may be significant benefit on the vascular health of patients with SCI. This study will assess the effect of a robotic-assisted gait-training (exoskeleton) program on central and peripheral hemodynamic markers in people with SCI.
Three arms of experimental design were used: Pedometer walking training (PWT), positive education and pedometer walking training (PEPWT), and pedometer walking (PW). Trained walking exercise was provided by a physical education expert three times per week, 45 minutes per session. Positive education was designed and led by a licensed psychologist. Six sessions of activities targeted participants' self-strength, competence and self-efficacy in walking exercise; positive relations with others; and positive emotions about life and healthy lifestyle. Of 150 participants, 60, 60 and 30 were randomly assigned to PWT, PEPWT, and PW, respectively. Demographic information, Chinese Happiness Inventory (CHI), regular walking exercise and six-minute walking distance were assessed before and after the intervention.
Introduction: studies on resistance training of low intensity associated with blood flow restriction in recent years, although there are still gaps that can be explored in relation to their physiological phenomena when associated with eccentric training. In this way, from there the exploration becomes relevant the investigation of eccentric training associated to an RFS. Objective: To analyze and compare the effects of a high intensity and low intensity intensive resistance training associated with an RFS (TREAI-RFS and TREBI-RFS) with a high intensity eccentric resistance training without RFS (TREAI) in knee extensors. Method: The study will consist of 45 male participants, allocated from a stratified randomization into three groups: TREAI (n = 15), TREAI-RFS (n = 15) and TREBI-RFS (n = 15). Participants underwent a training program with a minimum of 40% without RFS, 80% with RFS and 40% with CVS of CVIM, 3 times a week, and the outcomes of muscle strength, muscle structure, power test and Endothelial growth will be assessed one week before, the fourth week and one week after the end of the training program. In addition, clinical markers of perception and recovery effort are investigated before and after a session. The graph used is descriptive and descriptive, as it is used as a model of analysis of variance for the analysis of replications without a two-factor scheme, which provides detailed information on how the measures are repeated, neither. A whole statistical analysis can reach the level of significance of 5%.
In clinics, many scales have been developed to examine daily living activities and function in children with idiopatic toe walking. "The Idiopatic Toe Walking (ITW)" was developed in 2010 by Cylie M.Williams, contains 21 items which measure medical, birth & developmental history and assessment. The aim of the investigator's study was to investigate translating the ITW scale and using it in clinics reliably and valiably with a Turkish version of ITW in children with idiopatic toe walking.
Today's children have become increasingly inactive and unfit, with >50% of children not meeting the recommended 60 min of moderate-to-vigorous physical activity. Previous research has suggested that acute aerobic exercise of moderate intensity was associated with improved cognition manifested by improved performance and increased P3 amplitude, a neuroelectric indicator that reflects the amount of attentional allocation, in tasks requiring cognitive control. While minimal evidence exists to support potential mechanisms underlying the transient effects of exercise on brain and cognition, research suggests that phasic changes in the locus coeruleus-norepinephrine (LC-NE) (as measured by salivary alpha amylase (sAA)) system are a potential mechanism for explaining the acute effect of exercise on brain and cognition. Accordingly, the aim of this study is to examine the mechanisms linking acute aerobic exercise to improved cognitive control as well as the underlying neuroelectrical activities in children, using electroencephalography (EEG) and event-related potentials (ERPs). We hope to gain a better understanding of the role of acute exercise and cognitive and brain health. The results from this study will help identify mechanisms linking acute exercise to enhanced cognitive performance in children. Our hypothesis is that exercise-induced phasic increases in sympathetic nervous system activity will mediate the effect of a single bout of exercise on brain function, cognition, and standardized achievement test performance.
A 12 weeks technology enhanced home exercise (TEHE) program using mobile technologies that provide immediate feedback and send reminder messages to improve exercise motivation is developed. Investigators combine this TEHE program with techniques including auricular point pressure (APA) and brief mindfulness body scan (MBI). This study will examine the feasibility of the TEHE program and combined programs, and ascertain the effect of TEHE program alone, the combined programs on fatigue and biological markers among cancer survivors. Main Research Variable(s): The independent variables are the 12-week program of TEHE alone, APA alone, combined APA and TEHE (TEHEplus) and combined MBI and TEHE (TEHE-MBI). Outcome variables are fatigue, physical activity, contributing factors of fatigue and biomarkers. Design: Repeated measures randomized controlled trial. Setting: Participants will be recruited through the Comprehensive Cancer Center, Johns Hopkins University. Sample: Participants diagnosed with non-metastatic solid tumor cancer; who had completed all primary cancer treatment (surgery, chemotherapy, and radiation therapy )within at least 3 months OR non-metastatic prostate cancer completed all primary cancer treatment and have hormone therapy for at least 6 month, OR participants diagnosed with solid tumor cancer; who are receiving immunotherapy for at least 3 months before enrollment, aged 21 years or older, experiencing fatigue in the past 7 days on average of ≥ 3/10, able to participate in a moderate-intensity exercise training program, self-report ability to complete the 6 min walk test with a perceived exertion of 3 or below, and can communicate in English. Methods: Participants who meet the inclusion criteria will be randomly assigned to the TEHE only, APA only or TEHEplus or TEHE-MBI or control group. All exercise groups (TEHE) will be offered a 12-week exercise program through an online communication. In additional to the TEHE, the TEHEplus group will receive an instruction on how to apply the pressure on the ear points through online meeting/communication. The TEHE-MBI group will perform 5 min mindfulness body scan daily. The control (usual care) group will report participant's fatigue level daily. At the end of week 12, participants will answer open-ended questions about participant's opinions on the programs. Fatigue will be assessed and blood will be drawn before and after the program.
High intensity interval training (HIIT) has recently emerged as a time efficient alternative to conventional endurance exercise, conferring similar or superior benefits in terms of metabolic and performance adaptations in both athletic and non-athletic populations. Some of these physiological adaptations include augmented mitochondrial biogenesis and improved substrate metabolism in peripheral tissues such as skeletal muscle. However, nutritional strategies to optimise the adaptations to HIIT have yet to be established. Recent evidence suggests that acute nutritional status can affect the molecular regulation of genes mediating substrate metabolism and mitochondrial biogenesis. Moreover, preliminary evidence suggests that completion of exercise in fasted conditions augments some of these exercise-induced adaptations compared with the fed state. Given the fact that the transient molecular adaptations to acute exercise mediate long-term physiological adaptations, an investigation into the effects of different nutritional interventions on metabolic and performance responses to HIIT is warranted. The purpose of this study is to determine the effects of fasted vs. fed-state (Whey Protein) HIIT on metabolic and performance adaptations in the acute (single exercise session) and chronic (3 weeks, 9 exercise sessions) phases. The primary hypothesis is that different pre-exercise feeding conditions (e.g. fasted placebo vs. Whey protein fed) will result in divergent physiological adaptations in terms of skeletal muscle metabolism and performance, both in response to a single HIIT session and a chronic HIIT intervention.
The purpose of this study will be to determine if personalized moderate intensity exercise training combined with high intensity interval training is more effective at improving training responsiveness than moderate intensity exercise training alone? This question will be addressed holistically be creating a composite score to assess training responsiveness. Additionally, individualized biological variability will be calculated in order to quantify training responsiveness using a personalized criterion. It is hypothesized that personalized moderate intensity exercise training combined with high intensity interval training will be more effective at improving comprehensive training responsiveness when compared to moderate intensity exercise training alone?
The purpose of this study is to develop and test a brief program to help overweight people become more physically active. We plan to design a program that teaches people how to become more active by identifying how fitness enables them to live their lives better. Participants will be asked to complete questionnaires and wear a device that tracks their exercise for 1 week. If accepted into the study, they will receive a 1 day program designed to help them exercise more. Then they will receive phone calls and emails for support after the program. Finally, participants will come in 3 and 6 months after the program to complete the same questionnaires and wear the exercise tracker again. The study is primarily interested in increasing exercise levels, and so we hope to see participants exercising more after the program than they were before. We will also ask them questions (via the questionnaires) that tell us the degree to which they are exercising based on their one desires and values, as opposed to doing it because they were told to.
