Filter by:Patients with newly diagnosed gestational diabetes will be recruited. The control group with get routine diet and exercise counseling. The intervention group will be instructed to get moderate-to-vigorous intensity exercise; they will walk on a treadmill one time with supervision in order to be instructed how hard to work. All participants will keep an exercise log for 3 weeks and will wear an accelerometer for 1 week. The primary outcome is glucose control, specifically the need for medication in treatment of their diabetes. The hypothesis is that moderate or greater intensity exercise will better control glucose and lead to less need for medication management.
Beta-alanine, as a method to increase muscle carnosine, has been shown to enhance muscle buffering capacity and delay fatigue. Various fatigue tests have been utilized to examine the effectiveness of beta-alanine supplementation. The physical working capacity test has been used to show significant increases in physical working capacities following supplementation. The physical working capacity tests were originally developed by Moritani et al. 1981 and Devries et al. 1982 to measure the point of onset of muscular fatigue. It is hypothesized that beta-alanine will increase physical working capacity at heart rate threshold, thereby signifying a delay in fatigue.
Androgen Deprivation Therapy (ADT) is standard treatment for locally advanced or advanced Prostate Cancer (PC). The musculoskeletal toxicity associated with ADT is well established, leading to a decrease in muscle mass, increased fat percentage, weight gain, sexual dysfunction and increased risk of depression, fatigue, diabetes, cardiovascular disease and reduced quality of life. Numerous studies have shown an association between physical activity, physical capacity and quality of life in cancer patients and recent epidemiological research suggest that regular, moderate-intensity physical activity may have a positive effect on survival in men with prostate cancer. Within exercise physiology there is new evidence pointing to recreational soccer as a unique form of intermittent exercise that effectively stimulates aerobic and anaerobic energy delivery systems, leading to beneficial musculoskeletal, metabolic and cardiovascular adaptations of importance for health. It is our overall hypothesis that 12 weeks of recreational soccer training 2-3 times per week will improve the health profile of PC patients receiving ADT treatment.
This study evaluated the efficacy of a 12-week Internet intervention to help sedentary older adults adopt and maintain an exercise regimen. A total of 368 men and women over 55 years of age (x = 60.3; SD 4.9 ) were recruited and screened on line. They randomized into treatment and control groups and assessed at pre-test, 12 weeks, and at six months. The multivariate model was significant at posttest (p = .001; large effect size) and at six months (p = .001; medium effect size). At posttest, intervention participation showed significant improvement on 13 of 14 outcome measures compared to the control group. At six months, treatment group participants were found to maintain large gains compared to the Ctrl participants on all 14 measures.
Rationale: Proteins released from muscle during and shortly after exercise, often referred to as myokines, may be central to our understanding of the cross-talk during and after exercise between skeletal muscles and other organs, in particular the liver. So far only a few myokines are identified (e.g. IL-6, IL-8, IL-15, TNF-alpha). Taking into account the role of these several known myokines in developing insulin resistance, revealing new putative myokines might provide valuable information and a direction for future research on the pathogenesis and treatment of type 2 diabetes mellitus. Objective: The objective of the present study is to identify novel myokines, expression of which is altered in skeletal muscle after a single bout of exercise. Study design: experimental study. Study population: Ten healthy, male subjects between 40 and 60 years of age and BMI < 30 kg/m2, will participate in this study. Intervention: A single exercise bout that consists of one hour one-legged cycling on a adapted recumbent cycle ergometer at a submaximal rate. The non-exercising leg will serve as control for the exercising leg. Main study outcomes: Main study outcomes include upregulation of genes in skeletal muscle after exercise (with a focus on genes encoding myokines) and changes of blood plasma levels of selected proteins after exercise.
The purpose of this pilot study is to estimate the effect size of a contingency management procedure that reinforces walking at rates consistent with the American College of Sports Medicine recommendations of 10,000 or more steps per day in older adults. We expect that participants randomized to the contingency management intervention will increase walking to a greater degree than those assigned to a standard care condition.
Background: - Many people who have traumatic brain injury (TBI) have low levels of physical fitness. Low physical fitness causes severe fatigue that reduces the ability to perform routine daily activities, and may also cause increased depression, anxiety, or sadness. Aerobic exercise, such as treadmill walking or running, improves physical fitness in most people and may also decrease fatigue and improve mood. However, more information is needed to determine if exercise improves these conditions in people who have TBI. Objectives: - To examine the effect of an aerobic treadmill walking exercise program on physical fitness, fatigue, and mood in people with TBI. Eligibility: - Individuals between 21 and 45 years of age who had a nonpenetrating traumatic brain injury at least 6 months before participating; able to understand oral and written English language, give informed consent and sign a consent form; are physically inactive (including activities related to both job and recreation); and are able to stand and walk on a treadmill safely without help. Design: - This study requires 4 testing visits and 36 exercise visits over 14 weeks. - The first and third testing visits will last about 4 hours and the second and final testing visits will take about 2 hours. - Testing visits will consist of a medical history and physical examination, completion of questionnaires (about fatigue, daily physical activity, sleep quality, mood, and overall quality of life), tests of thinking and a treadmill exercise test. - Participants will have treadmill exercise training 3 days per week for 12 weeks. Each session includes a check-in, warm-up, treadmill walking at the training heart rate, and cool-down. Thirty-two of the sessions will last for about 1 hour, and four of the sessions will include questionnaires to fill out and will last about one-and-a-half hours. - After completing the exercise training program, participants will have a final testing visit to complete the questionnaires (about fatigue, daily physical activity, sleep quality, mood, and overall quality of life), tests of thinking and a treadmill exercise test....
About 32 healthy subjects are subjected to 4 weeks of exercise, 4 weeks of washout and 4 weeks of sedentary life style, randomization decides whether they start with exercise or with being "couch potatoes". All participants are also randomized to also consume 150 g of blueberries on exercise days or not. The exercise is constituted of 5 km running 5 days a week during the 4 week period. The exercise period and the "couch" period are started and ended with a 5 km run at maximal speed and the fasting blood samples for cardiovascular risk factors are measured before and after this run, ie 8 times in total.
This study will compare the effect of two doses of exercise on energy intake and body weight. The comparison will be between three groups; two exercise groups and a control group. The exercise groups will not be provided with a dietary intervention and the study design also includes a non-exercise control group. E-Mechanic trial can make important contributions to understanding of the role of exercise dose in weight management. While it is accepted that regular exercise plays an important role in general health, the exact role of exercise in prevention of weight gain, weight loss and prevention of weight regain remains poorly understood despite exercise being widely prescribed for these purposes. The idea that current weight management exercise recommendations may produce increased energy intake (or other forms on compensation) resulting in disappointing weight loss is an important public health issue. The finding of this study could help shape future exercise and weight loss recommendations and treatment plans.
Preeclampsia and other high blood pressure disorders of pregnancy are a significant cause of both maternal and fetal complications of pregnancy. To date, there is no known "cure" for preeclampsia, but studies have shown that exercise may lower the risk of preeclampsia and high blood pressure disorders in pregnancy. Resistance training also lowers blood pressure, and may be easier to perform in a pregnant population, leading to higher compliance. The investigators propose to perform a novel prospective study of a resistance training regimen on blood pressure in pregnant patients at high risk for developing preeclampsia or high blood pressure.
