Abstract

Testosterone boosters (TB) are multi-ingredient dietary supplements that have gained popularity among athletes and the general population. However, certain ingredients in TB are associated with adverse events. The aim of the present study was to analyze dietary TB supplements available for sale online on shop.bodybuilding.com and amazon.com in ten distribution area markets. We evaluated the top five best-selling TB and the most frequently used ingredients of 50 selected TB and the evidence for their efficacy and safety, as well as legislation, statements in the European Union (EU) and sports organizations such as International Olympic Committee (IOC), International Society of Sports Nutrition (ISSN), Australian Institute of Sport (AIS) and World Anti- Doping Agency (WADA). Among 50 TB, 361 components and 98 ingredients were identified. The following ingredients were included in the final review: fenugreek, D- aspartic acid (DAA), 3,3′-diindolylmethane (DIM) or indole-3-carbinol (I3C), Eurycoma longifolia, Cordyceps spp., and ecdysteroids. In EU an authorized health claims refer to few ingredients in TB, mainly minerals, vitamins. Some ingredients were recognized by international sports organizations such as the ISSN, AIS, and WADA and some were identified as unauthorized ingredients/novel food in the EU. Selected ingredients can possibly increase the risk of endocrine system dysregulation. [ABSTRACT FROM AUTHOR]

Abstract

Evaluating anti-doping measures is essential to optimise their effectiveness. Comparing sporting results that have a higher doping prevalence, such as weightlifting, before and after the implementation of anti-doping measures may serve as an effectiveness indicator. The results of the most successful weightlifters of both sexes in two time periods, 2009–2015 and 2016–2022 were analysed. The Sinclair Total (ST) to compare the relative strength of weightlifters from different weight categories was calculated. A significant decrease in the ST during 2016–2022 (p < 0.001) in athletes of all ages and both sexes overall was reported. When analysed by age, there was a decrease in ST in juniors and seniors of both sexes (p = 0.010 and p < 0.001, respectively), but not in youth. There was a decrease in the ST in senior men (p < 0.001), junior women (p < 0.001) and senior women (p < 0.001). In elite weightlifting, adult athletic results declined during 2016–2022, which may partly be explained by the implementation of new methods to detect long-term anabolic androgenic steroid metabolites as well as other policies. This may highlight the effectiveness of these methods both in the prevention and detection of anti-doping rule violations. [ABSTRACT FROM AUTHOR]

Abstract

Injuries of the metatarsal bones in football are relatively rare and in most cases are localized in the fifth metatarsal. The gold standard of the diagnosis of fractures in this area can be X-rays, which in most cases allows verifying the diagnosis. The treatment tactics depend on the localization of the fracture according to Lawrence and Botte's classification: 3 zones of localization are distinguished. Fractures located in zones 2 and 3 belong to a high-risk group due to delayed consolidation and nonunion and therefore athletes are most often treated with osteosynthesis using intramedullary screws. The minimal recovery time for this type of treatment is at least 8 weeks. This report describes 7 cases of the fifth metatarsal bone fractures, located in zones 2 and 3 in professional football players who were treated with an immobilization boot, cryotherapy, nutritional supplements of calcium and vitamin D, and local injections of platelet-rich plasma, which contains numerous growth factors. The deadline for returning to regular training activities was 43 to 50 days, and there was no relapse of damage within 6 months of follow-up.
