In humans, hyperthermic episodes can be triggered by halogenated anesthetics [malignant hyperthermia (MH) susceptibility] and by high temperature [environmental heat stroke (HS)]. Correlation between MH susceptibility and HS is supported by extensive work in mouse models that carry a mutation in ryanodine receptor type-1 (RYR1(Y522S/WT)) and knockout of calsequestrin-1 (CASQ1-null), 2 proteins that control Ca(2+) release in skeletal muscle. As overheating episodes in humans have also been described during exertion, here we subjected RYR1(Y522S/WT) and CASQ1-null mice to an exertional-stress protocol (incremental running on a treadmill at 34°C and 40% humidity)...

The purpose of this article is to present a discussion of a young adult patient with exertional rhabdomyolysis. Rhabdomyolysis is the process of muscle tissue destruction and damage to the cell membrane, with subsequent release of the intracellular myocyte contents into the systemic circulation. This leads to the potential for the life-threatening systemic complications of electrolyte abnormalities, cardiac dysrhythmias, acute kidney injury, compartment syndrome, and disseminated intravascular coagulopathy...

CONTEXT:   Recent case reports on malignant hyperthermia (MH)-like syndrome in physically active populations indicate potential associations among MH, exertional heat stroke (EHS), and exertional rhabdomyolysis (ER). However, an expert consensus for clinicians working with these populations is lacking. OBJECTIVE:   To provide current expert consensus on the (1) definition of MH; (2) history, etiology, and pathophysiology of MH; (3) epidemiology of MH; (4) association of MH with EHS and ER; (5) identification of an MH-like syndrome; (6) recommendations for acute management of an MH-like syndrome; (7) special considerations for physically active populations; and (8) future directions for research...

Erythropoietin (EPO) is a well-known hormone that is clinically used for the treatment of anemia. Very recently, an increasing body of evidence showed that EPO could still regulate bioactivities of macrophages. However, the details about the immunomodulatory effect of EPO on macrophages are not fully delineated, particularly in the setting of renal damages. Therefore, in the present study, we determined whether EPO could exert an impact on the dynamics of macrophages in a well-established model of rhabdomyolysis-induced acute kidney injury and explored the potential mechanisms...

Among active component service members in 2016, there were 525 incident diagnoses of rhabdomyolysis likely due to physical exertion and/or heat stress ("exertional rhabdomyolysis"). The crude incidence rate in 2016 was 40.7 cases per 100,000 person-years. Annual rates of incident diagnoses of exertional rhabdomyolysis increased 46.2% between 2013 and 2016, with the greatest percentage change occurring between 2014 and 2015. In 2016, relative to their respective counterparts, the highest incidence rates of exertional rhabdomyolysis affected service members who were male; younger than 20 years of age; and black, non-Hispanic...

Exertional (exercise-induced) rhabdomyolysis is a potentially life threatening condition that has been the subject of research, intense discussion, and media attention. The causes of rhabdomyolysis are numerous and can include direct muscle injury, unaccustomed exercise, ischemia, extreme temperatures, electrolyte abnormalities, endocrinologic conditions, genetic disorders, autoimmune disorders, infections, drugs, toxins, and venoms. The objective of this article is to review the literature on exertional rhabdomyolysis, identify precipitating factors, and examine the role of the dietary supplement creatine monohydrate...

INTRODUCTION: Two potentially fatal syndromes, malignant hyperthermia (MH), an adverse reaction to general anesthesia, and exertional rhabdomyolysis (ER) share some clinical features, including hyperthermia, muscle rigidity, tachycardia, and elevated serum creatine kinase. Some patients with ER have experienced an MH event and/or have been diagnosed as MH susceptible (MHS). In order to assess the relationship between ER and MH further, we conducted a retrospective cohort study summarizing clinical and genetic information on Canadian patients with ER who were diagnosed as MHS...

PURPOSE: Exertional rhabdomyolysis can occur in individuals performing various types of exercise but it is unclear why some individuals develop this condition while others do not. Previous investigations have determined the role of several single nucleotide polymorphisms (SNPs) to explain inter-individual variability of serum creatine kinase (CK) concentrations after exertional muscle damage. However, there has been no research about the interrelationship among these SNPs. The purpose of this investigation was to analyze seven SNPs that are candidates for explaining individual variations of CK response after a marathon competition (ACE = 287bp Ins/Del, ACTN3 = p...

In view of the enormous popularity of mass sporting events such as half-marathons, the number of patients with exertional rhabdomyolysis or exercise-induced heat stroke admitted to intensive care units (ICUs) has increased over the last decade. Because these patients have been reported to be at risk for malignant hyperthermia during general anesthesia, the intensive care community should bear in mind that the same risk of life-threatening rhabdomyolysis is present when these patients are admitted to an ICU, and volatile anesthetic sedation is chosen as the sedative technique...

BACKGROUND: Exertional heatstroke is a life-threatening condition with high mortality because of the rapid progress of multiple organ dysfunction syndrome even if aggressive treatments are initiated rapidly. Mild to moderate hepatic injury is common in exertional heatstroke, while fulminant liver failure is rare. Extrapyramidal symptoms and pulmonary aspergillosis secondary to liver failure induced by exertional heatstroke have never been reported in prior cases. CASE PRESENTATION: A 25-year-old Han Chinese man presented with exertional heatstroke with fulminant liver failure, subsequent pulmonary aspergillosis, and extrapyramidal symptoms...

J Strength Cond Res 31(5): 1403-1410, 2017-The optimal resistance training program to elicit muscle hypertrophy has been recently debated and researched. Although 3 sets of 10 repetitions at 70-80% of the 1 repetition maximum (1RM) are widely recommended, recent studies have shown that low-load (∼30% 1RM) high-repetition (3 sets of 30-40 repetitions) resistance training can elicit similar muscular hypertrophy...

BACKGROUND & AIMS: In the United States, nearly 1000 annual cases of heat stroke are reported but the frequency and outcome of severe liver injury in such patients is not well described. The aim of this study was to describe cases of acute liver injury (ALI) or failure (ALF) caused by heat stroke in a large ALF registry. METHODS: Amongst 2675 consecutive subjects enrolled in a prospective observational cohort of patients with ALI or ALF between January 1998 and April 2015, there were eight subjects with heat stroke...

Rhabdomyolysis is a clinical syndrome resulting from the disintegration of muscle cell and spillage of toxic intracellular contents into circulation. Strenuous, unaccustomed exercise leads to exertional rhabdomyolysis and cause AKI. We report a 26-year-old female who developed white collar rhabdomyolysis with AKI after performing sit-ups (Super Yoga Brain) for 108 times in temple. She was managed with hemodialysis and supporting therapy. She made a full recovery after 4 weeks. Awareness of this condition and early diagnosis is highlighted...

BACKGROUND: Rhabdomyolysis is a pathologic condition in which intracellular muscle constituents leak into the blood circulation. It is usually caused by muscle trauma. "Spinning" is an indoor form of cycling where participants use a special stationary exercise bicycle with a weighted flywheel and undergo high-intensity cycling classes focusing on endurance. There have been several case reports in the literature of exertional rhabdomyolysis following spin class. METHODS: Our nephrology practices have diagnosed a number of cases of symptomatic patients presenting to our emergency departments following their first spin classes, with histories and creatinine phosphokinase levels diagnostic of exertional rhabdomyolysis...

Exertional rhabdomyolysis is characterised by muscle breakdown associated with strenuous exercise or normal exercise under extreme circumstances. Key features are severe muscle pain and sudden transient elevation of serum creatine kinase (CK) levels with or without associated myoglobinuria. Mild cases may remain unnoticed or undiagnosed. Exertional rhabdomyolysis is well described among athletes and military personnel, but may occur in anybody exposed to unaccustomed exercise. In contrast, exertional rhabdomyolysis may be the first manifestation of a genetic muscle disease that lowers the exercise threshold for developing muscle breakdown...

Any strenuous muscular exercise may trigger rhabdomyolysis. We report an episode of clinically manifested exertional rhabdomyolysis due to stationary cycling, commonly known as spinning. Reports of spinning-related rhabdomyolysis are rare in the English literature, and the current case appears to be the first such case reported in South Korea. A previously healthy 21-year-old Asian woman presented with severe thigh pain and reddish-brown urinary discoloration 24-48 hours after attending a spinning class at a local gymnasium...

Exertional rhabdomyolysis (ER) is a medical condition whereby damage to skeletal muscle is induced by excessive physical activity in otherwise healthy individuals. The individual performs so much activity that he/ she presumably depletes local muscle energy stores and muscle cells are unable to maintain cellular integrity, resulting in cell damage and the release of cellular contents, with resultant secondary complications. In the military services, the incidence of ER appeared to increase in the period 2004 to 2015...
