Metabolic myopathies are a diverse group of inherited genetic disorders that disrupt carbohydrate and fatty acid metabolism, leading to impaired production of adenosine triphosphate and consequently, compromised muscle function. In many of these conditions, regardless of the specific metabolic defect, physical exercise (PE) can induce rhabdomyolysis (RML), posing a significant health risk to patients. Except for Glycogen Stora...

Purpose Fat free mass (FFM) is considered the metabolically active component of human body and is positively associated with maximal oxygen uptake ( $${\text{VO}}_{2} {\text{max}}$$ VO 2 max ). However, FFM is composed of metabolically active and inactive subcomponents whose proportion can vary depending on body composition and clinical condition, possibly affecting such association. Although it is known that in facioscapulohu...

Purpose Work ability indicates an individual’s capacity to match job demands according to his/her physical and mental conditions and work circumstances. Occupational physicians should take into consideration the global health status of a worker in order to correctly assess if he/she is fit for the job. The aim of this study was to verify the association between fitness for work evaluation and Work Ability Index scores, as well...

Purposes In kettlebell sport (KS) half marathon, the lift of the kettlebell is required for the highest number of repetitions in 30 min. No data are available on cardiorespiratory and metabolic responses during this exercise routine. The aim of the study was to evaluate cardiopulmonary and metabolic responses to KS half marathon compared to 30 min treadmill running, chosen as a reference paradigm of aerobic exercise, at the sa...

Purpose In facioscapulohumeral muscular dystrophy (FSHD) fatigue is a major complaint. We aimed to investigate whether during isometric sustained elbow flexions, performance fatigability indexes differ in patients with FSHD with respect to healthy controls. Methods Seventeen patients with FSHD and seventeen healthy controls performed two isometric flexions of the dominant biceps brachii at 20% of their maximal voluntary contra...
