Rapid weight loss can increase the risk of acute kidney injury in wrestlers

Objective Restrictive diets, forced starvation or voluntary weight loss are attracting more and more attention from scientists. Overall trends show that about 80% of combat sports athletes use specific methods of reducing body mass. Rapid weight loss could be a risk factor for kidney-related adverse outcomes. This study aimed to examine the impact of high-intensity specific training combined with rapid weight loss in the first and without rapid weight loss in the second phases on body composition and biochemical markers of kidney function. Methods The study was conducted on 12 male wrestlers. Kidney function markers were measured, including blood urea nitrogen, serum creatinine, uric acid and serum Cystatin-C. Alterations in analysed markers were noted in both phases of the research. Results According to the data, a significant increase was noted in blood urea nitrogen (p=0.002), uric acid (p=0.000) and serum creatinine (p=0.006) during the first phase in comparison with the second phase. The levels of serum Cystatin-C were slightly elevated after both phases compared with the initial measurement. Conclusion It is evident that high-intensity specific training combined with rapid weight loss significantly affects the increase in kidney function markers compared with identical training without rapid weight loss. The findings in this study suggest that rapid body mass reduction is associated with an increased risk of acute kidney injury in wrestlers

The role of physical activity in workplace well-being: impacts on stress, productivity, and health: a narrative review

PurposeStress is a condition that can manifest itself as a distortion of the normal functioning of the body and mind. A fair amount can be positive for the achievement of work objectives, but when it is excessive, it can have repercussions in the workplace, worsening the quality of the work itself. Considering the well-known benefits of physical activity (PA), it can improve and prevent this and other negative conditions to which a worker is subjected. Therefore, this narrative review aims to investigate the current situation on workplace stress and the effects of PA on workers' health in both sedentary and non-sedentary jobs to raise awareness that PA can improve workers' quality of life.MethodsTo retrieve eligible articles on workplace stress and the effects of PA, a manual search was conducted on the following databases: PubMed, Google Scholar, and Web of Science. Articles published up to March 31, 2023 were included, with no limitation related to the start of the research period.ResultsPA appears to provide numerous benefits to workers in the workplace, from physical to mental improvements.ConclusionsPA is of considerable importance in improving the quality of life of workers, reducing stress, and improving productivity
