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

Primary Care Considerations for the Adolescent Wrestler

PURPOSE OF REVIEW

Adolescent wrestlers undergo intense physical combat. While guidelines are effective in keeping the sport safer, concerns specific to the adolescent wrestler may be missed at primary care visits without knowledge of the unique challenges faced by these athletes. The following review highlights important characteristics of the adolescent wrestler which are of interest to primary care providers.

RECENT FINDINGS

Recommendations for concussion management are evolving to gradual return-to-sport after physician clearance rather than total sport removal. Prolonged skin-to-skin contact also places athletes at greater risk of dermatologic infections, which often require removal from competition, treatment, and/or coverage. Finally, adolescent nutritional literature recommends limiting pre-match weight loss to 3-5% body weight due to noted kidney damage that may result from larger deficits. Adolescent wrestlers are more prone to acute injuries than chronic overuse injuries, with most injuries occurring above the trunk. Primary care providers should consider obtaining imaging to rule out severe injuries or referring to specialist providers. Current guidelines for skin infections require frequent pre-match skin checks and mandatory waiting periods when certain infections are identified. However, the primary care provider is well-equipped for more in-depth skin examination, discussion of skin hygiene, and appropriate treatment of skin infections. Athletes attempting to meet lower weight classes may put themselves at risk of acute kidney damage, under-fueling, and eating disorders. Current guidelines attempt to mitigate excessive weight changes in the adolescent wrestler during competition season, but primary care providers should emphasize healthier methods of weight fluctuation and look for indicators of physiological or psychological effects.

Prevalence of metabolic syndrome and its association with rapid weight loss among former elite combat sports athletes in Serbia

BACKGROUND

In terms of the potential influence of rapid weight loss (RWL) on the metabolic health of former combat sports athletes (CSA), the scientific literature is quite scarce. Therefore, the objective of the presented research was to determine the differences in metabolic syndrome (MetS) parameters and the prevalence of MetS between former athletes who performed RWL and athletes who did not.

METHODS

The sample of the presented study comprised 150 participants from Serbia, equally divided into two groups: 75 former athletes who had practiced combat sports and 75 ex-athletes of various other sports who did not practice RWL during their careers. The following parameters related to the MetS were evaluated: waist circumference, high-density lipoprotein cholesterol, systolic blood pressure, diastolic blood pressure, fasting glucose, and triglycerides. The oral glucose tolerance test (OGTT) was used to assess the participant's body response to sugar.

RESULTS

The RWL group had significantly higher both systolic (p < 0.001) and diastolic blood pressure (p < 0.001) compared to the group of athletes who did not practice weight reduction during their careers. Additionally, a tendency toward statistically significant differences between groups was recorded in the variable triglycerides (p = 0.069). Regarding OGTT, increased values of fasting blood glucose at the final measurement were revealed only in the RWL group (p = 0.003). The prevalence of MetS was substantially higher in CSA than in the control group (39.5% vs. 16.2%, respectively p = 0.002).

CONCLUSIONS

This study suggests that former elite CSA who used RWL during their sports career are susceptible to negative metabolic alterations at the end of their competitive period.
