Filter by:B-alanine supplementation is highly efficient in increasing intramuscular carnosine content, leading to improved physical performance, especially in high-intensity exercises (HIIE). It seems that exercise per se can modulate carnosine content; however, it remains uncertain whether physical training or training status can influence B-alanine supplementation responses. Thus, this work aims to assess whether HIIE can increase B-alanine uptake by peripheral tissues and, more specifically, skeletal muscle and increase intramuscular carnosine synthesis. The volunteers will be evaluated in two conditions: intake of B-alanine + exercise (B-EX) and B-alanine intake only (B-Ala). This process will be divided into two blocks of six days (Thursday to Thursday - without the weekend) with a 4-6 weeks washout. In the B-EX block, a 20-minute HIIE session will be held. In the B-Ala block, the same procedures will be adopted for the B-EX block, with the replacement of the HIIE for 20 minutes of rest sitting on the cycle ergometer. We will evaluate the determination of muscle B-alanine, plasma, and urine, the gene expression of carnosine-related enzymes and transporters, the enzymes Carnosine Synthase 1 (CARNS1), carnosine dipeptidase 2 (CN2), taurine transporter (TauT), PAT1, and phosphorylated Na + / K + / ATPase. The hypotheses are: 1) acute physical exercise increases the uptake of B-alanine by the skeletal muscle; 2) this effect is mediated by the increased activity of the Na + / K + / ATPase pump; 3) this effect, when repeated over five training sessions, results in observable increases in β-alanine → carnosine conversion in skeletal muscle.
The purpose of this study aimed to evaluate the effect of the three-month Chan-Chung qigong program in improving physical functional performance and quality of life in patients with mild to moderate cognitive impairments.A quasi-experimental design was adopted. Subjects were recruited from cognitive impairments outpatients these subjects,41were assigned to the control group and 41 to the experimental group in which Chan-Chuang qigong was administered.
Hypoxic exposure increases right ventricular (RV) afterload by triggering pulmonary hypertension, with consequent effects on the structure and function of the RV. Improved myocardial contractility is a critical circulatory adaptation to exercise training. However, the types of exercise that enhance right cardiac mechanics during hypoxic stress have not yet been identified. This study investigated how high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) influence right cardiac mechanics during hypoxic exercise (HE).
Cardiovascular disease, and especially myocardial infarction, is the most common cause of death globally, and is particularly common in older individuals. Practical measures that can reduce both the prevalence and incidence of cardiovascular disease are of great value. It is well known that regular physical activity has a protective effect against the development of cardiovascular diseases such as acute myocardial infarction. It has been shown that physical activity can improve the function of the heart and blood vessels, but it is less well known how physical activity can affect the risk of formation of dangerous blood clots, and thus the risk of heart attack and stroke. In a cross-sectional study it has been shown that a physically active lifestyle can reduce the risk of blood clot formation, but experimental evidence for the importance of a period of physical activity for the risk of blood clot formation is lacking. New methods have been set up for measuring the coagulation profile. The analyzes are performed on a blood sample and allow a thorough determination of platelet reactivity as well as an innovative measure of how the microstructure of a possible blood clot would develop. In this project, these methods is used to examine how physical activity, in the form of team sports, affects the coagulation profile of elderly men and women. The increasing age-related risk of cardiovascular disease is associated with endothelial dysfunction and decrease in capillary density, and it has been shown that initiation of capillary growth is a successful method to treat cardiovascular disease. Therefore, this project will also investigate how a longer period of physical activity, in the form of team sports, affects capillary density and endothelial function in men and women aged 60-70 years. Both men and women will be recruited, as it is still unknown whether men and women respond differently to physical activity in relation to coagulation profile, susceptibility to blood clots and capillary density.
At menopausal transition, the risk of cardiovascular diseases increases. This is partly due to aging, but largely also the loss of estrogen, which has many positive effects on the circulation and protects against cardiovascular diseases. It has been suggested that the loss of estrogen may have a negative impact on the otherwise well-documented health promoting effects of exercise training, and that the time after menopause may be crucial for the effect of exercise training on the vascular function, and therefore also for the risk of thrombosis. Literature regarding the effect of exercise training on the risk of thrombosis is limited, and especially in women. The purpose of the present study is to investigate whether the same effects of exercise training in relation to thrombosis is achieved if the exercise is initiated early compared to late after menopause. The aim is to provide knowledge-based recommendations regarding exercise. Teams sports will be used as the training intervention, because team sports benefits physical health and also includes a social element.
To analyze the effects of altering the time of ingestion of participants' habitual medication (i.e., metformin, statins, ARAII/IACE) and meals around the time of exercise training (exercise fasted or fed) on the improvement of metabolic syndrome factors (hypertension, insulin sensitivity, dyslipidemia, and obesity). There will be a preliminary study of the effects of training "time-of-day" on the primary study outcomes.
The primary aim of this proposal is to identify changes in the volume of highly metabolic organs (liver, kidneys, and brain) that occur as a physiological adaptation to exercise training and lower the resting energy expenditure. Secondary aims are to identify changes in the metabolic efficiency of muscle in low levels of physical activity and evaluate the effects on components of total daily energy expenditure including the sleeping metabolic rate (SMR) and diet induced thermogenesis (DIT).
Exercise training is beneficial for both health and performance. Histamine has been shown to be involved in the acute exercise response. The current study addresses the role of histamine H1/H2 receptor signaling in the chronic training-induced adaptations. Results from this study will yield more insights into the molecular mechanisms of adaptations to exercise training.
The purpose of this study is to determine if a virtual reality training of foot placement with or without visual cues about the location of the foot in the environment would improve locomotion-related function in persons in the chronic stage of stroke. Participants were randomly assigned to receive twice per week, for a total of 2 weeks' training with visual cues (control group) or without (experimental group). It was hypothesized that the experimental group would be able to place the foot closer to the target when stepping and have more symmetrical gait. So far, 22 stroke patients completed the experiment. Preliminary results support the hypothesis. This project is still ongoing.
This randomized controlled trial will determine the effects of 12-weeks of wheelchair user-modified upper-body rowing on both traditional cardiometabolic risk factors in SCI manual wheelchair users.
