This study aims to compare the effects of aerobic exercise with or without addition of resistance exercise to usual care in individuals treated with anthracyclines for lymphomas and to compare exercise effects to age- and sex-matched individuals with no prior history of malignant diseases.
Patients with post-Covid-19 syndrome are at high risk of developing cardiovascular diseases 12 months after acute infection of COVID-19. We recently revealed that these patients have elevated muscular sympathetic nerve activity (MSNA), vascular dysfunction, impaired cardiac diastolic function, and reduced functional capacity. Considering that these outcomes are independent predictors of cardiovascular mortality, it is urgent to restore the cardiovascular health of these patients. High resistance inspiratory muscle strength training (IMST) at 75% of pressure inspiratory (PImax) performed at home (5 min/session, 5-7 times/week per 6 weeks) reduces the MSNA, improves the endothelial function and lowers blood pressure in different populations. Based on these findings, IMST (75% PImax) is an excellent therapeutic option for patients with post-COVID-19 syndrome. Therefore, the aim of the present proposal is to test whether IMST (75% PImax) reduces sympathetic activity, improves vascular function, and restores cardiac function, evoking an increase in functional capacity in patients with post-COVID-19 syndrome. To test these hypotheses we will conduct a randomized, double-blind, sham-controlled clinical trial to test these hypotheses.
Motor learning is crucial for human daily routine, involving the acquisition of new movements. It consists of an online acquisition phase followed by offline consolidation, where motor memory is organized into stable representations. Acquisition can be achieved through physical practice (PP, overt repetition of movement) or mental rehearsal using motor imagery (MI). Recent studies suggest that high-intensity interval physical exercise (HIIE) enhances motor learning, particularly during consolidation, by promoting neural plasticity mediated by brain-derived neurotrophic factor (BDNF). However, the impact of HIIE on sequential motor consolidation with PP or MI remains poorly understood. In contrast, sleep deprivation (SD) reduces BDNF release and neural plasticity. Limited research has explored the effects of SD on motor acquisition, especially sequential motor learning. Considering the opposing effects of HIIE and SD, performing HIIE after SD may protect motor consolidation processes. This study aims to examine the influence of HIIE on sequential motor learning using PP or MI under both sleep-deprived and normal sleep conditions. Six groups, each comprising 12 participants, will learn an 8-item bimanual sequence. - MI group: acquired the motor sequence mentally during training - MI+HIIE group: acquired the motor sequence mentally and achieve a HIIE before the consolidation - PP: acquired the motor sequence physically - PP+HIIE group: acquired the motor sequence physically and achieve a HIIE before the consolidation - SD+PP group: one night of sleep deprivation prior physical motor acquisition with PP and consolidation - SD+PP+HIIE group: one night of sleep deprivation prior physical motor acquisition and HIIE before consolidation. All groups will be tested on the sequence at the beginning and the end of the acquisition phase (pre- and post-acquisition), and after the physical exercise (i.e. HIIE) or the rest period (post-exercise). Hypothesis of this study are : - Acute physical exercise (HIIE) would enhance the consolidation of motor memory (post-exercise) after physical and mental acquisition (PP,MI) compared to conditions without exercise. - One night of sleep deprivation would affect the acquisition and consolidation of motor learning. Physical exercise would compensate for the detrimental effects of sleep deprivation on the consolidation of motor learning.
Background: Heart failure (HF) is a chronic disease with a very important and increasingly severe social and health impact with a prevalence of 6.8% in Spain. HF with preserved ejection fraction (HFpEF) represents approximately 50% of all patients with HF. In the absence of pharmacological treatments that have succeeded in reducing mortality or morbidity in this pathology, it is recommended that interventions be directed at prevention, symptomatic treatment of HF and treatment of comorbidities to avoid exacerbations, thus physical exercise is recognized as an important adjunct in the treatment of HF and is recommended by the guidelines of the American College of Cardiology (ACC)/American Heart Association (AHA) and the European Society of Cardiology (ESC). Currently, aerobic exercise is the most studied physical exercise in this population, but in recent years high-intensity interval training (HIIT) and the combination of aerobic exercise with strength training (combined exercise) have emerged. Objectives: The overall objective of this study is to compare the effectiveness of combined training and HIIT on exercise capacity, diastolic function, endothelial function, and arterial stiffness in patients with HFpEF. The specific objectives of this study are: a) to compare the effectiveness of combined training and HIIT on quality of life in patients with HFpEF and b) to analyze the cost-effectiveness of combined training and HIIT versus conventional treatment in patients with HFpEF. Methodology: The ExIC-FEp study will be a single-blind randomized clinical trial with 3 arms (combined exercise, HIIT and a control group), conducted at the Health and Social Research Center of the University of Castilla-La Mancha, to analyze two types of supervised physical exercise in patients with HFpEF for 6 months. Patients with HFpEF will be randomly assigned (1:1:1) to the combined exercise, HIIT or control group. All participants will be examined, at baseline (prior to randomization), at three months (mid-intervention) and at six months (at the end of the intervention). Participants will undergo physical examination, echocardiography, maximal cardiopulmonary stress test, and measurement of endothelial function and arterial stiffness. In addition, sociodemographic variables, quality of life, physical activity, adherence to the Mediterranean diet, strength, spirometry and blood sampling will be measured. Expected scientific contributions: this randomized clinical trial will represent a a significant advance in the scientific evidence available on the efficacy of physical exercise in the treatment of HFpEF, through: (a) transfer of the results to physicians, nurses and patients; (b) dissemination of results through scientific articles, doctoral theses and participation in congresses; (c) press releases and press conferences with the aim of disseminating the research results to the population; (d) dissemination through social networks to improve the social impact; and (e) design and content development of a web page.
The intervention will be a physical exercise program for colorectal cancer patients during the adjuvant chemotherapy. The exercise program aims on reducing the side effects of the treatment and improving patients' quality of life. In addition, the investigators try to improve endurance and resistance training level, in order to achieve greater physical functionality, survival and general well-being. For this, the investigators will carry out an exercise program based mainly on muscular strength and cardiorespiratory condition. It will last 6 months, with a frequency of 3 days per week, including sessions of 60 minutes. Sessions will consist of three parts: warm-up, main part (endurance and resistance training), and cool down. An individualized and supervised progression of training will take place. The intensity levels will always be adjusted to the initial levels of the participants, always considering their preferences and comfort. Participants' preferences and exercise history will be considered through an initial interview. Motivational strategies based on self-determination theory will be applied, since it is one of the most used theories in the field of physical exercise. This theory proposes that all people need to feel competent, autonomous and socially related. If these three needs are satisfied, participants will develop more positive (autonomous) forms of motivation, which are related to better consequences such as vitality, enjoyment, quality of life and adherence to physical activity. In addition, motivational strategies will be applied for families and healthcare professionals. Before starting the program and at the end of it, each eligible patient will be evaluated through: - Physical activity: strength test of lower and upper limbs, agility test, stress test for cardiorespiratory fitness, physical activity levels, physical condition and body composition. - Psychological factors: autonomy support, basic psychological need satisfaction, motivation, quality of life, perceived barriers, depression, anxiety, hope, quality of life. - Clinical parameters: survival rate, side effects, biological factors, treatment delays and planned treatment completion.
