Abstract

Background: This study aimed to compare the Athlete Diet Index (ADI) and body composition between professional and nonprofessional athletes to better understand how differences in training and nutrition impact athletic performance and health.

Method: A comparative cross-sectional design was used to analyze 183 athletes (99 professional, 84 nonprofessional) from various sports disciplines in Tehran. Data were collected on body composition parameters, including fat mass (FM) and fat free mass (FM) using bioelectrical impedance analysis (BIA) and the ADI, a validated tool for assessing diet quality.

Results: The results revealed that professional athletes had significantly lower FM percentages (16.2% ± 7.1%) and higher FFM percentages (80.8% ± 6.8%) compared to their nonprofessional counterparts (FM 18.8% ± 9.9%, FFM 78.0% ± 9.6%). Additionally, professional athletes exhibited higher ADI scores, indicating better adherence to sports nutrition guidelines.

Conclusions: These findings highlight the benefits of structured training and personalized nutrition in achieving favorable body composition. This study underscores the importance of personalized nutrition strategies for optimizing athletic health and performance, particularly for nonprofessional athletes who may not have access to professional dietary guidance. Further research is needed to explore the long-term effects of dietary and training interventions on body composition and athletic performance across various athlete populations.

职业和非职业运动员饮食指数和身体成分的比较：比较横断面研究。

背景：本研究旨在比较专业和非专业运动员的运动员饮食指数（ADI）和身体成分，以更好地了解训练和营养的差异如何影响运动成绩和健康。方法：采用比较横断面设计对来自德黑兰不同体育学科的183名运动员（99名专业运动员，84名非专业运动员）进行分析。采用生物电阻抗分析（BIA）和ADI（一种经过验证的饮食质量评估工具）收集体成分参数数据，包括脂肪质量（FM）和无脂肪质量（FM）。结果：与非职业运动员（FM 18.8%±9.9%,FFM 78.0%±9.6%）相比，职业运动员的FM比例（16.2%±7.1%）显著低于职业运动员（16.2%±7.1%），FFM比例（80.8%±6.8%）显著高于职业运动员（78.0%±9.6%）。此外，专业运动员表现出更高的ADI分数，表明更好地遵守运动营养指南。结论：这些发现强调了结构化训练和个性化营养在获得良好身体成分方面的益处。这项研究强调了个性化营养策略对于优化运动员健康和表现的重要性，特别是对于那些可能无法获得专业饮食指导的非专业运动员。需要进一步的研究来探索饮食和训练干预对不同运动员群体的身体成分和运动表现的长期影响。
