Abstract：
BACKGROUND: This study aimed to ascertain the influence of somatotype structures on athletic performance among professional athletes.
METHODS: Twenty-eight professional athletes, comprising 14 handball players and 14 volleyball players, were enlisted as participants for this study. As per the methodology, evaluations encompassing explosive power, strength, flexibility, horizontal jump, agility, sprint, and hand-foot reaction tests were conducted. Following physiological assessments, parameters including body mass index, body fat percentage, and somatotype were computed. The impact of athletes\' somatotype structures on their athletic performance was investigated employing linear regression analysis.
RESULTS: The endomorphy value serves as a negative predictor (r2=0.159) for explosive power, whereas the mesomorphy (r2=0.204) and ectomorphy (r2=0.379) values act as positive predictors of explosive power. Ectomorphy value negatively predicts grip strength (r2=0.399) and back strength (r2=0.214), while mesomorphy value positively predicts grip strength (r2=0.233) and back strength (r=0.338; r2=0.114). Mesomorphy value negatively predicts flexibility (r2=0.247), long jump (r2=0.311), sprint (r2=0.256), and reaction (r2=0.133), whereas ectomorphy value positively predicts flexibility (r2=0.225), long jump (r2=0.463), sprint (r2=0.393), and reaction (r2=0.208).
CONCLUSIONS: This study showed a correlation between various somatotype structures and indicators of athletic performance. Within this framework, it can be inferred that mesomorphy and ectomorphy values serve as reliable predictors of athletes\' performance. Furthermore, individuals with elevated mesomorphy values may exhibit enhanced strength performance, while those with higher ectomorphy values may demonstrate superior flexibility performance. Hence, when designing training programs aimed at enhancing athletes\' performance attributes, it is imperative to account for the influence of body type on such performances.

摘要：
背景：本研究旨在确定职业运动员体型结构对运动表现的影响。
方法：28名专业运动员，包括14名手球运动员和14名排球运动员，被列为这项研究的参与者。根据方法，包括爆炸力的评估，力量,灵活性,水平跳跃,敏捷性,sprint,并进行了手脚反应测试。在生理评估之后，包括体重指数在内的参数，身体脂肪百分比，并计算体型。采用线性回归分析研究了运动员体型结构对其运动表现的影响。
结果：内形态值用作爆炸能力的负预测因子（r2=0.159），而介晶（r2=0.204）和外晶（r2=0.379）值是爆炸力的正预测因子。外形态值负预测握力(r2=0.399)和背强度(r2=0.214)，而中胚值正预测握力（r2=0.233）和背强度（r=0.338；r2=0.114）。中形值负预测柔性(r2=0.247)，跳远（r2=0.311），sprint（r2=0.256），和反应（R2=0.133），而变形值正向预测灵活性(R2=0.225)，跳远（r2=0.463），sprint（r2=0.393），和反应(r2=0.208)。
结论：本研究显示了各种体型结构与运动表现指标之间的相关性。在这个框架内,可以推断，中胚态和外胚态值是运动员表现的可靠预测因子。此外，介晶值升高的个体可能表现出增强的强度性能，而那些具有较高的变形值的人可能表现出优异的柔韧性能。因此，在设计旨在提高运动员表现属性的训练计划时，必须考虑身体类型对这种表现的影响。
