[The effect of a rapid decrease in body weight and enriching rations with microelements on various functions of the...

Area of Science:

• Sports Medicine
• Biochemistry
• Human Physiology

Context:

• High-skill athletes often undergo rapid weight loss for competition.
• Physiological changes during extreme weight reduction are not fully understood.
• The impact of dehydration and nutrient restriction on athletic performance and health is a concern.

Purpose:

• To investigate the effects of a 5-percent body weight reduction on specific blood serum markers and immune responses in athletes.
• To evaluate the impact of sauna use for weight reduction on physiological parameters.
• To determine the efficacy of nutritional and pharmacological interventions in mitigating negative physiological changes during weight loss.

Summary:

• Rapid weight loss (5% body weight over 5 days) via restricted water, fat, and carbohydrate intake reduced ceruloplasmin and lysozyme activity in athletes.
• Sauna-induced weight loss led to decreased peroxidase activity and lower iron and copper content in blood cells, alongside trace element loss in sweat.
• Supplementation with trace elements, vitamins, and bendasole hydrochloride during sauna-induced weight loss prevented adverse effects and improved system functions.

Impact:

• Highlights the physiological costs of rapid weight loss methods in athletes.
• Suggests that trace element and vitamin supplementation can counteract negative impacts of weight reduction.
• Provides evidence for the beneficial role of bendasole hydrochloride in conjunction with nutritional support for athletes undergoing weight management.
