Abstract
BackgroundThere is an increasing concern on cardiometabolic health in young professional athletes at heavy-weight class.ObjectiveOur cross-sectional survey aimed to evaluate the prevalence of metabolic syndrome and clustering of metabolic risk factors in a population of young and active professional athletes of strength sports in China.MethodsFrom July 2006 to December 2008, a total of 131 male and 130 female athletes of strength sports were enrolled. We used two criteria provided by the Chinese Diabetes Society (2004) and the National Cholesterol Education Program's Adult Treatment Panel III (2002) to define the metabolic syndrome and its individual components, respectively.ResultsRegardless of their similar ages (mean: 21 years) and exercise levels, athletes in the heaviest-weight-class with unlimited maximum body weight (UBW) boundaries (mean weight and BMI: 130 kg and 38 kg/m2 for men, 110 kg and 37 kg/m2 for women) had significantly higher prevalence of metabolic syndrome than did those in all other body-weight-class with limited body weight (LBW) boundaries (mean weight and BMI: 105 kg and 32 kg/m2 for men, 70 kg and 26 kg/m2 for women). Prevalence of metabolic syndrome using CDS criteria (UBW vs. LBW: 89% vs. 18% for men, 47% vs. 0% for women) and its individual components, including central obesity, hypertension, hypertriglyceridemia, low high-density lipoprotein-cholesterol levels, and impaired fasting glucose, were all significantly higher in athletes at the heaviest weight group with UBW than all other weight groups with LBW.ConclusionsOur study suggests that professional athletes of strength sports at the heaviest-weight-class are at a significant increased risk of cardiometabolic disease compared with those at all other weight categories. The findings support the importance of developing and implementing the strategy of early screening, awareness, and interventions for weight-related health among young athletes.
Highlights
In recent decades, epidemic proportions of cardiometabolic disorders, such as diabetes, hyperlipidemia, non-alcoholic fatty liver disease (NAFLD), cardiovascular and cerebrovascular diseases, become an increasing threat to public health in the general population

Athletes in some of athletic disciplines, such as weightlifting and judo, are divided into several subclasses according to their body weights, of which there are no limits in the maximum body weight
Summary
Epidemic proportions of cardiometabolic disorders, such as diabetes, hyperlipidemia, non-alcoholic fatty liver disease (NAFLD), cardiovascular and cerebrovascular diseases, become an increasing threat to public health in the general population. There is evidence for strength athletes with a higher risk for diabetes and metabolic syndrome after their retirement than those of other sports disciplines [5,6,7]. Body size has played a key role in successful performance for athletes of strength sports and American football linemen [8]. At the recent 11th China national game, the average weights of weightlifting athletes at the top 3 heaviest-weight-class were 152 kg in men and 140 kg in women. Most of these athletes with large body sizes appear to be overweight or obese; Characteristics*.
