Rhabdomyolysis is the result of skeletal muscle tissue injury and is characterized by elevated creatine kinase levels, muscle pain, and myoglobinuria. It is caused by crush injuries, hyperthermia, drugs, toxins, and abnormal metabolic states. This is often difficult to diagnose perioperatively and can result in renal failure and compartment syndrome if not promptly treated. We report a rare case of inadvertent rhabdomyolysis and compartment syndrome in a bodybuilder undergoing minimally invasive cardiac surgery...

Ecdysteroids are secondary metabolites, widely distributed in the animal and plant kingdoms. They have a wide range of pharmacological effects in vertebrates, including mammals, most of which are beneficial for humans. Therefore, they have become compounds of interest for the pharmaceutical industry due to their adaptogenic, anabolic, hypoglycaemic, hypocholesterolaemic and antimicrobial activities, which are still being researched. Nowadays, ecdysteroids are present as active ingredients in bodybuilding supplements...

Children and adolescents may participate in sports that favor a particular body type. Some sports, such as gymnastics, dance, and distance running, emphasize a slim or lean physique for aesthetic or performance reasons. Participants in weight-class sports, such as wrestling and martial arts, may attempt weight loss so they can compete at a lower weight class. Other sports, such as football and bodybuilding, highlight a muscular physique; young athletes engaged in these sports may desire to gain weight and muscle mass...

Orthorexia nervosa (ON) describes a pathological obsession with healthy eating to avoid ill health. In the Swedish context, ON is also understood in terms of unhealthy exercise. Fitness gyms are popular health-promoting places, but exercise-related problems, disordered eating and ON-like behaviour are increasing. Personal trainers (PTs) play an important role in detecting unhealthy behaviours. The aim of the present study was to illuminate PTs' understandings of healthy and unhealthy exercise and eating behaviours in relation to orthorexia nervosa in a fitness gym context...

Anabolic androgenic steroids (AAS) are performance enhancing drugs commonly used by athletes and bodybuilders to improve appearance and athletic capability. Unfortunately, these testosterone derivatives can be associated with serious and potentially irreversible side effects, and can impact multiple organ systems. It is important that physicians be familiar with these adverse consequences so that they can appropriately counsel patients whom they suspect of AAS-abuse. In this chapter, we will review the negative effects of these compounds on various organ systems in men using AAS...

β-hydroxy-β-methylbutyrate (HMB) is a metabolite derived from leucine and its ketoacid alpha-ketoisocaproate. Leucine has a role in regulating protein synthesis in muscle cells, and HMB seems to be a key active metabolite in such regulation. HMB has been shown to modulate muscle protein degradation by inhibiting the ubiquitin-proteasome proteolytic pathway, to up-regulate protein synthesis via the mTOR pathway, and to stabilize cell membranes via the rate limiting enzyme to cholesterol synthesis HMG- coenzyme A reductase...
