Norwegian Danish Spontaneous Coronary Artery Dissection Exercise Study

The goal of this randomized clinical trial is to determine whether a supervised high-intensity interval training (HIIT) program can safely improve cardiorespiratory fitness and overall health in adults who have previously had spontaneous coronary artery dissection (SCAD), a non-atherosclerotic cause of heart attack that often affects younger women. Participants are women and men aged 18 years or older, with a confirmed SCAD at least 12 weeks before enrollment, who are medically stable, cleared for exercise testing, and able to attend supervised sessions. The main questions the study aims to answer are: * Does a 12-week supervised HIIT program lead to a greater improvement in cardiorespiratory fitness (measured as peak oxygen uptake (VO2peak, ml/kg/min)) compared with usual care, without increasing the occurrence of major adverse cardiovascular events (MACE)? * Is a 12-week HIIT program safe for people with prior SCAD, assessed by the occurrence of MACE? Researchers will compare two randomized groups (1:1): * Group A (HIIT): Participants take part in a supervised treadmill-based high-intensity interval training program twice per week for 12 weeks, with continuous heart rate monitoring and clear rules for stopping in case of symptoms. * Group B (usual care): Participants continue with the exercise advice they have already received after SCAD, without a structured supervised program and with a recommendation to avoid high-intensity exercise (above 85% of maximum heart rate). Participants in both groups will: * Undergo cardiopulmonary exercise testing (CPET) at baseline and after 12 weeks to measure VO2peak and blood pressure response during exercise. * Have blood tests (for example cholesterol and cardiac biomarkers), blood pressure, heart rate and weight measured. * Complete validated questionnaires on quality of life (World Health Organization Quality of Life-BREF (WHOQOL-BREF)), anxiety (Generalized Anxiety Disorder 7-item scale (GAD-7)), and depression (Patient Health Questionnaire-9 (PHQ-9)). * Have activity data recorded using the MIA activity-tracking app and heart rate data will be uploaded simultaneously from portable devices. Safety will be monitored continuously. Major adverse cardiovascular events (MACE), including death, recurrent heart attack (SCAD or non-SCAD), heart failure, stroke or transient ischemic attack, extracoronary arterial dissection, cardioversion or implantable cardioverter-defibrillator (ICD) therapy, will be recorded during the 12-week intervention and a 25-week follow-up period (total study duration per participant: 37 weeks).

Effect of High Intensity Interval Training on Strength, Endurance and Flexibility

Strength and endurance are essential components for physical fitness of any individual. High intensity interval training provides time efficient benefits for strength and endurance training. Physical Therapy professionals and students need physical fitness for effective clinical performance of patients. There is limited research regarding physical performance of physical therapists itself

The Feasibility of LVHIIT on Inpatient Stroke Rehab

The objective of this study is to explore the safety and feasibility of conducting low-volume, high-intensity interval training (HIIT) on a total body recumbent stepper (TBRS) in persons with stroke in an inpatient rehabilitation setting.

Investigation of the Effects of High-Intensity Interval Exercise and Moderate-Intensity Continuous Exercise on Limb Volume, Functional Capacity, and Quality of Life in Patients With Lipedema

This randomized controlled clinical study aims to investigate and compare the effects of high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT), when combined with intermittent pneumatic compression (IPC) therapy, on limb volume, functional capacity, pain, fatigue, anxiety, depression, sleep quality, and quality of life in women with lipedema. Lipedema is a chronic, progressive adipose tissue disorder primarily affecting women, characterized by abnormal and symmetrical fat accumulation in the lower extremities that does not improve with weight loss or limb elevation. It is often misdiagnosed as obesity or lymphedema, leading to delayed treatment. Lipedema causes pain, swelling, bruising, mobility limitation, and reduced quality of life. Conservative treatment options include compression therapy, manual lymphatic drainage, and exercise. IPC is a non-invasive treatment used to reduce limb volume and pain while improving function and quality of life. Exercise is also a cornerstone of conservative management, but the optimal exercise intensity for lipedema remains unclear. In this study, 69 female patients aged 18-65 years diagnosed with lipedema according to Halk and Damstra criteria will be randomly assigned into three groups: IPC + Home-based walking program IPC + High-Intensity Interval Training (HIIT) IPC + Moderate-Intensity Continuous Training (MICT) All participants will receive 15 IPC sessions (3 times per week for 5 weeks). The exercise programs (HIIT or MICT) will continue for 10 weeks, supervised by a physiotherapist. The home-based group will be encouraged to walk ≥10,000 steps daily using a pedometer application. Primary outcome: Change in limb volume measured by circumferential measurements and the truncated cone formula. Secondary outcomes: Pain (VAS), functional capacity (6-Minute Walk Test), muscle strength (dynamometry), pressure pain threshold (algometry), physical activity (IPAQ-SF), lower extremity function (LEFS), quality of life (SF-12), sleep quality (PSQI), fatigue (FSS), and anxiety/depression (HADS). Measurements will be taken at baseline (T0), after 15 IPC sessions (T1), and after 30 total sessions or 10 weeks (T2). The investigators hypothesize that both HIIT and MICT combined with IPC will provide superior improvements in physical and psychological outcomes compared to IPC with a home-based walking program alone.

Optimizing Aerobic Fitness in Older Adults

Hospitalization and treatment for cardiovascular disease is one of the main contributors to disability in older adults. Moderate intensity continuous aerobic and resistance training have been the cornerstone of cardiac rehabilitation (CR) for decades to remediate hospital-acquired functional deficits, but some groups receive less or minimal functional benefit from this training. The proposed studies seek to optimize recovery of aerobic fitness and physical function among older cardiac patients using a novel high intensity training regimen with the long-term goal of reducing subsequent disability and improving clinical outcomes.

Effects of Upper Extremity Low Volume HIIT in Heart Failure

This study was planned to investigate the effects of upper extremity low-volume high-intensity interval training (LV-HIIT) on physical and cognitive function in patients with heart failure with preserved ejection fraction(HFpEF).The research was planned as a randomized controlled trial. Patients with clinically stable HFpEF at cardiology clinic will be included in the study. These cases will be randomly divided into two groups: intervention group and control grup. After 8 weeks intervention physical functions before and after treatment; functional exercise capacity, arm exercise capacities , peripheral muscle strength , fatigue cognitive functions; anxiety and depression and fear of movement will be evaluated.

"HIIT Med Kiloene".

In Denmark, 15% of children are overweight and 5% obese. Obese children and adolescents have several metabolic complications, such as pre-diabetes, hypertension, dyslipidaemia, and excess fat deposition in liver, already at a young age. In addition, obese children suffer from psychological issues such as low quality of life and anxiety. These findings underline the need for effective treatment strategies to eliminate the development of obesity-related complications. We will conduct a two-study project in order to investigate the effect of high-intensity interval training (HIIT) and lifestyle intervention in obese children and adolescents on several metabolic risk factors and psychological problems. Study 1 is a randomized controlled study including 150 obese children and adolescents recruited from the municipal obesity clinics in Northern Jutland. Study 1 will examine the value of a group based HIIT intervention in the children's local environment and investigate the association between HIIT and psychosocial wellbeing. Study 2 is a randomized controlled study including 60 severe obese children and adolescents recruited from Videnscenter for Børn og Unge med Overvægt (VIBUO) at Aalborg University Hospital. Study 2 investigates the effect of HIIT and lifestyle intervention on metabolic and cardiovascular risk factors. In both studies, the children and adolescents are 9-16 years old and will be randomized to lifestyle guidance or a combination of HIIT and lifestyle guidance for 3 months, both followed by 9 months of lifestyle guidance only. Our primary goal is to show the efficacy of HIIT and facilitate the establishment of permanent targeted training propositions for obese children and adolescents with local anchoring in the municipalities.
