Filter by:There are experimental evidences of the importance of high intensity exercises in health outcomes improvement. However, there are limited knowledge about possibility to affect health outcomes in adolescents through exercises programs introduced into physical education (PE) lesson. Moreover, there is lack of the studies identifying people who do not respond to stimuli, as well as examining potential determinants of non-responsiveness. Thirdly, there are no studies examining the modification of exercise dose that should be reflected in the response in such individuals. Aim of this human experiment is to examine the effects of one cycle of 8-weeks high-intensity interval training (HIIT) implemented in physical education lesson on: (1) body composition (proportions of the body fat to the body muscles), (2) resting blood pressure, (3) physical efficiency. Study are conducted for two years (two cycles). Each year 300 students of two secondary schools, are involved in project: 15-16-year-olds in first year, 18-19-year-olds in second year. Students are divided in experimental groups -performing 8-weeks (twice a week) cycle of HIIT implemented into PE lesson, and the control groups - students following a typical PE programme. Each cycle consists of two parts. First part is related to the 8 weeks of HIIT training, while second part is related to the dose-expose study. All participants are examined during project before (Pre), after (Post) and Follow-Up intervention. Second part is planned after a break of several months. Persons who do not respond to the exercise stimulus in the first part will follow individually modified programmes. They will be measured before and after this additional training. To examine the assumed HIIT-induced changes in participants the investigators will apply: (1) anthropometric measurements: body height and weight, and BMI will be calculated, (2) body mass composition (fat and muscle mass), (3) resting blood pressure, (4) beep test which is field motor specific test to assess physical efficiency. The results of this project will help to answer the fundamental questions about HIIT induced morphological and physiological effects in adolescents, what is important from scientific and public health point of view. Particularly, in view of the growing pandemic of obesity, common elevated blood pressure and steadily declining physical fitness in children and adolescents.
The aim of this study is to investigate whether there are the additive effects when implementing both high-intensity interval training (HIIT) and probiotics simultaneously on improving cardiorespiratory endurance and metabolism in middle-aged women.
The goal of this study is to learn how the number of weekly exercise sessions affects improvements in fitness in healthy university aged students. The main question it aims to answer is how training frequency affects improvements in fitness. Participants will complete a pre-testing sessions to assess fitness level and sprint performance. Following this participants are assigned to one of four groups. A group that exercises 2 days a week, a group that trains 3 days a week, a group that trains 4 days a week, or a no-exercise control group. Participants in this group will not complete any training and allow the researchers to compare the exercise groups to a group that didn't train. Each participant will train for 4 weeks. During each training session participants will complete 4-6 30 second all-out sprints with 4 minutes of rest between each. Participants will complete the same tests they did during the pre-testing session following the 4 weeks of training to see how frequency affects improvements.
The primary objective of this proposal is to determine the effects of post-exercise peanut consumption on long-term aerobic and resistance exercise training adaptations in middle-aged men and women. We will determine the impact of peanuts on exercise training-induced improvements in muscle strength, gains in muscle mass, and improvements in cardiorespiratory fitness and metabolic capacity.
The aim of this observational study is to investigate the association between mid-life changes in cardiorespiratory fitness and the risk of breast cancer incidence and mortality among Swedish women. The main questions to answer are: - Are changes in cardiorespiratory fitness associated with the risk of being diagnosed or dying from/with breast cancer later in life? Participants performed at least two occupational health assessment tests, which consisted of a submaximal ergometer cycle test, measurement of body mass and height to calculate BMI, and a questionnaires on physical and life style habits.
Home-based exercise interventions were the only alternatives to attenuate physical deconditioning and ameliorate traditional and emergent cardiovascular risk factors progression during the COVID-19 outbreak. Benefits in physical and psychological health have only been reported in adults without intellectual and developmental disability (IDD). The purpose of this study is to compare home vs gym-based delivery exercise modes of two 8-week supervised aerobic training regimes on cardiorespiratory fitness and arterial structure and stiffness in adults with IDD. It is hypothesized that home- and gym- based exercise delivery modes will be equally effective in improving cardiorespiratory fitness and overall arterial heath, although in an intensity dependent manner. A secondary analysis examining changes in blood pressure and body composition will be performed.
Potential benefits of a nitrate juice supplement to improve skeletal muscle function and associated physical capacity will be studied in patients with Long COVID. Consenting patients with Long-COVID will be randomized to receive Beet-It nitrate beverage group versus a nitrate-depleted placebo beverage. Both groups will receive physical therapy at the long COVID Clinic at VAPHS with therapeutic goals to improve strength, balance, inspiratory, and aerobic capabilities. Physical therapy will last for 2 weeks and include 2 or 3 sessions with a physical therapist a week depending on each individual's exercise tolerance. These sessions can take place on-site or at home (or a hybrid combination) All participants will undergo functional assessments and tissue assessments before and after the 14-day study intervention.
To explore the safety and compliance of a wearable telemedicine device that can receive basic vital signs in real time, and its active supervision mode with real-time adjustment of exercise prescription for preoperative prehabilitation exercises in patients at home; and to evaluate the effectiveness of preoperative prehabilitation exercises in a telemedicine active supervision mode in patients undergoing thoracoscopic lung tumour resection, taking into account the patient's cardiopulmonary exercise test, postoperative complications and quality of life scores.
The aim of this study is to examine the effects of a kindergarten-based, parent-involved intervention during the upper kindergarten year (K3) on physical activity and physical fitness in preschool children.
In this proposal, the investigators challenge the assumption that following the physical activity guidelines implies benefit for ALL adults, and that if benefit is not achieved in response to first line therapy, it will be by simply exercising more. Thus, for improving cardiorespiratory fitness and cardiometabolic risk factors, unanswered questions include: 1) To what extent, regardless of increasing exercise intensity or amount, is exercise not associated with benefit? Demonstration of a resistance to benefit through exercise in a substantial number of adults would be a novel and important finding, would counter the assumptions of many if not most health care practitioners, and could have immediate and direct application in all health care settings. 2) To what extent will non-responders to first line therapy (150 min/wk) be required to increase exercise intensity or amount to achieve benefit? 3) To what extent will failure to improve CRF segregate (be associate with) with cardiometabolic risk factors? The investigators propose that adults who remain exercise resistant for improvement in CRF and cardiometabolic risk despite increasing amount or intensity are at high risk of metabolic disease and consequently, are candidates for alternative treatment strategies.
