INTRODUCTION: Although there is potential for the menstrual cycle to impact psychophysiological responses to exercise, there has been a paucity of studies investigating this aspect, specifically in the context of high-intensity interval training (HIIT). PURPOSE: This exploratory study aimed to examine the psychophysiological responses to HIIT over the menstrual cycle. METHODS: Twenty-three healthy and physically active young women were recruited...

BACKGROUND AND PURPOSE: Surgical removal of a vestibular schwannoma (vestibular schwannoma resection; VSR) results in a unilateral vestibular hypofunction with complaints of dizziness and imbalance. Although the anatomic lesion is permanent, recovery of balance and diminution of dizziness occurs through central neurophysiologic compensation. Compensation of the system is maintained through daily activity. Unfortunately, interruption of stimulus, such as decreased activities due to illness, can cause decompensation...

The methacholine challenge test (MCT) is a standard evaluation method of assessing airway hyperresponsiveness (AHR) and its severity, and has significant clinical value in the diagnosis and treatment of bronchial asthma. A consensus working group consisting of experts from the Pulmonary Function and Clinical Respiratory Physiology Committee of the Chinese Association of Chest Physicians, the Task Force for Pulmonary Function of the Chinese Thoracic Society, and the Pulmonary Function Group of Respiratory Branch of the Chinese Geriatric Society jointly developed this consensus...

After a mild traumatic brain injury (mTBI), dizziness and balance problems are frequently reported, affecting individuals' daily lives and functioning. Vestibular rehabilitation is a standard treatment approach for addressing these issues, but its efficacy in this population remains inconclusive. A potential reason for suboptimal outcomes is the lack of objective monitoring of exercise performance, which is crucial for therapeutic success. This study utilized wearable inertial measurement units (IMUs) to quantify exercise performance in individuals with mTBI during home-based vestibular rehabilitation exercises...

OBJECTIVE: People receiving peritoneal dialysis may receive health benefits from physical activity or exercise. However, on-going uncertainty and fear regarding safety may result in this population missing out on the health benefits of participation. The aim of this study was to explore the characteristics and frequency of physical activity and/or exercise-related side-effects (e.g., symptoms such as pain or shortness of breath) and negative health events (e.g., stroke or hyper/hypoglycemia) experienced by people receiving peritoneal dialysis...

INTRODUCTION: Vestibular hypofunction is associated with dizziness, imbalance, and blurred vision with head movement. Vestibular rehabilitation is the gold standard recommendation to decrease symptoms and improve postural stability. The Clinical Practice Guidelines for vestibular hypofunction suggest home exercises 3-5 times daily, but patient adherence is a problem, with compliance rates often below 50%. METHODS: An app was developed to increase engagement with home exercises by providing exercises as games...

KEY CLINICAL MESSAGE: Middle-aged male athletes, with or without underlying coronary artery disease, exhibiting exercise induced blood pressure (BP) variability and diabetes can have an increased risk of developing atrial fibrillation (AF). Assessment in athletes should include long-term arrhythmia monitoring. In addition, it is important to exert patients beyond their calculated target heart rate (HR) during an exercise stress test to detect exercise-induced AF. We suggest this strategy be specifically used for athletes with complaints of intermittent palpitation and chest pain...

The aim of the study was to investigate any indication of diminished orthostatic tolerance as a result of fatiguing intensive acute concentric exercise with a successive isometric wall-sit followed by an orthostatic stress test, with a special focus on any distinguishable alterations due to a delayed-onset muscle soreness effect. The exercise protocol was carried out among nineteen (10 female, 9 male) junior swimmers from the Hungarian National Swim Team. All athletes showed a positive orthostatic stress test right after our exercise protocol...

BACKGROUND: Cognitive dysfunction in people with relapsing-remitting multiple sclerosis can improve with cognitive rehabilitation or exercise. Similar effects have not been clearly shown in people with progressive multiple sclerosis. We aimed to investigate the individual and synergistic effects of cognitive rehabilitation and exercise in patients with progressive multiple sclerosis. METHODS: CogEx was a randomised, sham-controlled trial completed in 11 hospital clinics, universities, and rehabilitation centres in Belgium, Canada, Denmark, Italy, UK, and USA...

INTRODUCTION: Small gastrointestinal stromal tumors (GISTs) are often asymptomatic. However, large tumors can cause symptoms like abdominal pain and GI bleeding. We experienced a unique case where a giant GIST was incidentally found by CT scanning during emergency treatment for dizziness. PRESENTATION OF CASE: A 61-year-old man presented temporary dizziness after exercising three days ago before his admission. Enhanced CT scan of the abdomen and pelvis revealed a large circular mass in the right upper abdominal cavity, with a maximum cross-sectional size of approximately 132 mm × 155 mm...

Exercise-induced tachycardia-dependent atrioventricular block with a normal electrocardiogram at rest is rare. Herein, we present a case of a 65-year-old woman with exercise-related chest suppression and treadmill exercise test-induced second- and third-degree atrioventricular blocks with narrow QRS wave and normal resting electrocardiogram. High atrioventricular block leads to tissue and organ insufficiency, resulting in exercise intolerance, dyspnea, dizziness, and syncope. Ths diagnosis was exercise-induced high-degree atrioventricular block...

A 16-year-old boy reported an episode of dizziness related to intense training six months before an episode of aborted sudden death. The screening required for competitive sports practice was normal. There were no personal or familial antecedents of sudden death or heart disease. After winning a triathlon competition, he experienced a cardiac arrest episode. He received defibrillation with the return of spontaneous circulation. A medical evaluation that included electrocardiogram (ECG) and echocardiogram had normal results...

BACKGROUND: Worldwide, iron deficiency anemia is the most prevalent nutritional deficiency disorder and the leading cause of anemia in children, especially in developing countries.
