: The authors hypothesized that variants within genes, such as COL5A1, COL3A1, COL6A1, and COL12A1, that code for connective tissue components of the musculoskeletal system may modulate susceptibility to exercise-associated muscle cramping (EAMC). Specifically, the aim of this study was to investigate if the COL5A1 rs12722 (C/T), COL3A1 rs1800255 (G/A), COL6A1 rs35796750 (T/C), and COL12A1 rs970547 (A/G) polymorphisms are associated with a history of EAMC.

: Dietary supplements containing 1,3-dimethylamylamine (DMAA) have been determined to be illegal by the Food and Drug Administration (FDA); although banned, the products are still widely available for purchase. Adverse effects reported include cardiac arrest, hemorrhagic stroke, and death. Nonetheless, such products remain popular among young people because of advertised claims of exercise performance enhancement and fat burning. We describe a case of a young man who took such a supplement and suffered a cardiac arrest. Notably, the product consumed was not on the FDA list of substances containing DMAA. This case highlights the importance for clinicians to be aware of the potential harm of the DMAA-containing products by maintaining a high index of suspicion in otherwise healthy individuals presenting with cardiac arrest. It is of particular importance to sports medicine physicians who are most involved in education and counseling of patients potentially at risk of taking such products.

Commotio cordis, sudden death with chest impact, occurs clinically despite chest wall protectors worn in sports. In an experimental model of commotio cordis, commercially available chest wall protectors failed to prevent ventricular fibrillation (VF). The goal of the current investigation was to develop a chest wall protector effective in the prevention of commotio cordis.

This study aimed to compare the immediate analgesic effects of 2 resistance programs in in-season athletes with patellar tendinopathy (PT). Resistance training is noninvasive, a principle stimulus for corticospinal and neuromuscular adaptation, and may be analgesic.
