This study analyzed publicly available autopsy reports of male bodybuilders under the age of 50 who reportedly died from cardiovascular-related events. A general Google search with the terms “dead bodybuilders” was performed on 10 February 2022. Six reports were available for review and analysis. Bodybuilders had the following means: age (±SD) = 36...
Background:
The purpose of this case study was to implement an evidence-based dietary approach to peaking for a bodybuilding competition and monitor its impact on body composition, muscle thickness (MT), intra-to-extra-cellular fluid shifts, subcutaneous thickness (ST), and hydration status. Secondarily, to document any adverse events of this peak...
Bodybuilding is a competitive endeavor where a combination of muscle size, symmetry, “conditioning” (low body fat levels), and stage presentation are judged. Success in bodybuilding requires that competitors achieve their peak physique during the day of competition. To this end, competitors have been reported to employ various peaking interventions...
The assessment of bone mineral density (BMD) is essential to skeletal health, and dual-energy x-ray absorptiometry (DXA) is a type of bone densitometer that is extensively used in both clinical and research settings. When changing a DXA system during longitudinal monitoring or multicenter studies, it is important to conduct cross-calibration betwee...
Dual-energy X-ray absorptiometry (DXA), bioimpedance spectroscopy (BIS), and ultrasound (US) are commonly used to estimate body composition, but each method has limitations. This study compared the body composition estimations of the three devices in college students. Ten males (23.7 ± 1.9 years; 171.9 ± 6.7 cm; 81.8 ± 11.4 kg) and twenty females (...

Abstract Background Energy drinks are often consumed by the general population, as well as by active individuals seeking to enhance exercise performance and augment training adaptations. However, limited information is available regarding the efficacy of these products. Thus, the purpose of this study was to determine the effects of a commercially...
Despite the lack of standardized terminology, building muscle and losing fat concomitantly has been referred to as body recomposition by practitioners. Although many suggest that this only occurs in untrained/novice and overweight/obese populations, there is a substantial amount of literature demonstrating this body recomposition phenomenon in resi...
Physique athletes often incorporate aerobic exercise as part of their exercise program to increase caloric expenditure for the purposes of improving their body composition. One method used by some physique competitors is to perform aerobic exercise in the fasted state under the assumption that low glycogen levels after an overnight fast allow for g...
Nontraumatic shoulder disorders are prevalent among weight-training participants as a result of training patterns as well as adaptive shoulder joint and muscle characteristics. This article presents a progressive approach to exercises designed to mitigate well known joint and muscle characteristics that have been associated with shoulder disorders....
Physique competitors focus on optimizing body composition through maximizing muscle mass and loss of body fat. Competitors frequently experiment with various methodologies purported to improve body composition, but often, there is a lack of evidence on their efficacy. Emerging evidence suggests that intermittent energy restriction (IER) methodologi...
