Type 2 Diabetes (T2D) is a condition characterized by acelerated aging and is associated to multiple comorbidities, and physical fragility and disabilitiy, all of which reduce life expectancy and quality of life. Physical exercise has been demonstrated to have metabolic and cardiovascular benefits in T2D. Also, lack of exercise and sedentary behavior are major predictors of cardiovascular morbidity and mortality and all-cause mortality. Some evidence suggests that individuals with T2D have a reduced exercise capacity and exercise tollerance compared to non-diabetic individuals.The reasons behind such difference are not thoroughly explored, but may be connected to acute and chronic effects of hyperglycemia. Reduced trainability might be a marker of early aging and physical disalbility. This study aims to define respiratory, cardiovascular, neuromuscular, inflammatory, hormonal and metabolic determinants of trainability in persons with T2D. Results will help to answer the question whether it is the low trainability that reduces exercise capacity or it is the low exercise participation that determines a low exercise capacity.
The goal of this study is to find out if doing a 16-week volleyball program integrated in physical education classes at school can make primary school students stronger, faster, and have better endurance. The study also wants to see whether the program can lead to changes in the students' body weight, body fat, and muscle mass.
The goal of this randomized controlled trial is to determine the effect of an intervention program with physical activity for 12 weeks on depression, social and emotional well-being and quality of life and health in adults with mild and moderate depression. The main questions it aims to answer are: 1. - To determine the association of physical activity levels, sedentary behavior, sleep patterns, physical condition, diet, and general health status with mental and social well-being, and quality of life in a large sample of adult patients diagnosed with mild or moderate depression. 2. - To examine the predictive capacity of physical activity, sedentary behaviors, and physical condition on mild and moderate depressive disorder. 3. - To study the effect of a period without an intervention program with physical activity (8 weeks without exercise intervention) on the variables studied. 4. - To examine the role of the endocannabinoid system on depression as well as its behavior after an intervention program of physical activity. Participants will be involved in a physical activity intervention program for 12 weeks. Researchers will compare intervention group and control group to see if an intervention program with physical activity for 12 weeks improve depression, social and emotional well-being and quality of life and health in adults with mild and moderate depression.
Workplaces rely on upper heat stress limits provided by the American Conference of Governmental Industrial Hygienists (ACGIH) to manage the health and safety of workers in hot environments. This is primarily achieved by interspersing work with rest periods, the length of which is dictated by environmental conditions and work intensity, to maintain core temperature at or below 38.0°C (equivalent to a 1°C increase in body core temperature above resting levels). However, these guidelines employ a "one size fits all" approach to exposure limits that does not consider individual variation between workers. Moreover, they fail to provide direction on the safe, initial stay times before these heat-mitigation controls should be employed (i.e., rest breaks) in conditions exceeding upper heat stress limits. While recent work has generated estimates of the initial stay times for young to older men before heat-mitigation controls are required for moderate-intensity work, this information is limited to a single work bout and does not consider a second work bout preceded by an extended rest period (e.g., lunch) or next day effects. This is a key consideration, as prolonged work in the heat has been shown to cause next-day impairments in heat dissipation in older men. Further, it remains unclear if the application of the prescribed ACGIH work-rest allocations thereafter would alleviate increases in core temperature for the duration of the work period (e.g., start of shift versus post-lunch period). This project will address these knowledge gaps by determining if refinements in initial stay times for moderate-intensity work (represents the average work effort of physically demanding occupations) in the heat (26°C wet-bulb globe temperature) may be required for young and older adults for i) a second work bout that is preceded by an extended rest period such as a lunch break, and ii) a work bout performed on the next day. This includes assessing the efficacy of the prescribed ACGIH work-rest allocations to mitigate increases in core temperature beyond safe limits (>38.0°C, equivalent to a >1°C increase in body core temperature above resting levels) during these work periods. Given the known sex-differences in heat loss that can modulate core temperature regulation during an exercise-heat stress, the investigators will conduct separate analysis to identify modulating effects of biological sex on the initial stay times and effectiveness of the work-rest allocation as a heat-alleviation control.
Sleep deprivation has long been thought to modulate thermoregulatory function. Seminal work on sleep deprivation and thermoregulation has demonstrated that sleep-deprived individuals experience greater elevations in core temperature during exercise-heat stress due to reductions in the activation of local heat loss responses of cutaneous vasodilation and sweating. However, it remains unclear 1) if reductions in local heat loss responses would compromise whole-body heat loss (evaporative + dry heat exchange) and 2) if differences exist, are they dependent on the heat load generated by exercise (increases in metabolic rate augments the rate that heat must be dissipated by the body). Further, much of the understanding of the effects of sleep deprivation on thermoregulation has been limited to assessments in young adults. Studies show that aging is associated with reduction in cutaneous vasodilation and sweating that compromise whole-body heat loss exacerbating body heat storage during moderate- and especially more vigorous-intensity exercise in the heat. However, it remains unclear if sleep deprivation may worsen this response in older adults. The purpose of this study is therefore to evaluate the effects of sleep-deprivation on whole-body total heat loss during light, moderate, and vigorous exercise-heat stress and to assess if aging may mediate this response. To achieve this objective, direct calorimetry will be employed to measure whole-body total heat loss in young (18-30 years) and older (50-65 years) men during exercise at increasing, fixed rates of metabolic heat production of 150 (light), 200 (moderate), and 250 W/m2 (vigorous) in dry heat (40°C, ~15% relative humidity) with and without 24 hours of sleep deprivation.
People with severe mental disorders have a mortality rate 2 to 3 times higher than that of the general population, largely due to the presence of comorbidities, with a predominance of cardiovascular disease. This population has a higher risk of developing metabolic syndrome compared to the healthy population. Several factors are involved. The usual pharmacological treatment in people with severe mental disorder is a risk factor for the development of metabolic syndrome and deterioration of physical condition. This is generally compounded by poor health care, high-calorie diets, a sedentary lifestyle, difficulties in coping with life situations that generate emotional states (anxiety and/or depression) that result in unhealthy lifestyle habits related to food, activity, interpersonal relationships, sleep, consumption habits (tobacco, alcohol and drugs) and other environmental factors. Physical exercise has been proposed as one of the most effective treatments to reverse the negative consequences of low levels of physical activity in this population. However, the mechanism of action of exercise on health status and the optimal "dose" and intensity of exercise to achieve the greatest number of benefits with respect to cardiometabolic health in patients with severe mental disorder are unknown.The study will be carried out at the Mental Health Rehabilitation Unit of Navarra, a center under the Mental Health Management of Osasunbidea, where people between 18 and 65 years of age with a diagnosis of severe mental illness in a situation of clinical stability receive treatment.The sample will be composed of 100 participants from consecutive admissions to the Rehabilitation Unit. The subjects will be randomized into 2 groups; a control group that will receive the usual specialized care and an intervention group, which in addition to receiving the usual rehabilitation treatment, will undergo a 6-week multicomponent physical exercise program performed 2 days per week. The effects of exercise on the inflammatory profile, metabolic parameters, physical condition, cognitive function, vascular function, muscle strength, health-related quality of life, lifestyle habits (diet, activation, sleep, substance use) and mood will be evaluated.
A problem often observed during exercise training is oxygen desaturation exclusively during exercise in some patients. In the case of exercise-induced desaturation, it may be suggested to train these patients in interval training to limit exercise-induced desaturation. Interval training consists of alternating active phases of short duration (often 30 seconds to 1 minute) followed by a short active or passive recovery phase of equivalent duration to the previous phase. Investigators therefore hypothesise that interval training on a cycloergometer or treadmill can limit exercise-induced desaturation in COPD patients. The aim of the study is to observe the evolution of pulsed oxygen saturation between a continuous training session and a interval training session.
The "TakeCare!" study addresses the problem that vocational students of nursing care cope with great physical and psychological demands during their daily routines. To meet these demands, the Bavarian curriculum for generalist nurses has adopted the promotion of physical activity-related health competence (PAHCO) for vocational students. However, it must be assumed that the concept has not yet been adopted comprehensively across the Bavarian nursing landscape. Therefore, the "TakeCare!" study tackles the question of how PAHCO can be implemented most appropriately in Bavarian nursing schools. Drawing on experiences from the project PArC-AVE, three different dissemination approaches will being tested and compared with a control group. A total of 16 nursing schools from different regions of Bavaria will be assigned to four different study arms (cluster-randomized design). In the long term, the project aims to derive recommendations for all nursing schools in Bavaria.
