To document the relation between serum creatinine concentration and body mass index in elite athletes from five different sports, and to study potential differences among athletes performing different sports with different features and requirements.
Before the start of the competitive season, serum creatinine was measured in 151 elite athletes from five different sports: rugby (n = 44), soccer (n = 27), alpine skiing (n = 34), sailing (n = 22), cycling (n = 24). Pearson's correlation analysis was used to evaluate the relation between serum creatinine and body mass index (BMI). Analysis of variance and unpaired Student's t test were used to compare creatinine concentration and BMI in different sport disciplines.
In the whole group of athletes, a positive correlation between serum creatinine and BMI was found (r = 0.48, p<0.001). Significant differences in creatinine concentration and BMI were found between athletes competing in different sports: their mean (SD) values were respectively 1.31 (0.12) mg/dl and 28.83 (2.41) for rugby players, 1.27 mg/dl (0.10) and 23.10 (1.01) for soccer players, 1.15 (0.11) mg/dl and 25.8 (1.50) for skiers, 1.08 (0.11) mg/dl and 26.93 (2.36) for sailors, and 0.91 (0.07)mg/dl and 21.33 (1.21) for cyclists.
There is a correlation between creatinine concentration and BMI in elite athletes competing in different sports characterised by different kinds of training, competitive season, and involvement of aerobic and anaerobic metabolism. Interpretation of creatinine concentrations in male athletes should consider professional status as well as the specific sport performed. All athletes should be monitored with consecutive creatinine assessments, using as the baseline the concentration determined before the start of training and the competitive season, but taking into consideration the specific sport performed and the BMI until equations that include creatinine and factors that affect its concentration are used.
记录来自五项不同运动项目的精英运动员血清肌酐浓度与体重指数之间的关系，并研究从事具有不同特点和要求的不同运动项目的运动员之间的潜在差异。
在竞技赛季开始前，对来自五项不同运动项目的151名精英运动员进行血清肌酐测量，这些项目包括橄榄球（n = 44）、足球（n = 27）、高山滑雪（n = 34）、帆船（n = 22）、自行车（n = 24）。采用Pearson相关分析评估血清肌酐与体重指数（BMI）之间的关系。使用方差分析和非配对学生t检验比较不同运动项目中的肌酐浓度和BMI。
在全体运动员中，发现血清肌酐与BMI之间存在正相关（r = 0.48，p<0.001）。在参加不同运动项目的运动员之间，肌酐浓度和BMI存在显著差异：橄榄球运动员的平均值（标准差）分别为1.31（0.12）mg/dl和28.83（2.41），足球运动员为1.27 mg/dl（0.10）和23.10（1.01），滑雪运动员为1.15（0.11）mg/dl和25.8（1.50），帆船运动员为1.08（0.11）mg/dl和26.93（2.36），自行车运动员为0.91（0.07）mg/dl和21.33（1.21）。
在以不同类型的训练、竞技赛季以及有氧和无氧代谢参与为特征的不同运动项目中参赛的精英运动员，其肌酐浓度与BMI之间存在相关性。对男性运动员肌酐浓度的解读应考虑职业状况以及所从事的具体运动项目。所有运动员都应通过连续的肌酐评估进行监测，以训练和竞技赛季开始前测定的浓度作为基线，但要考虑所从事的具体运动项目和BMI，直到使用包含肌酐和影响其浓度的因素的公式。
