The present study aimed to determine the link between low-carbohydrate diet score (LCDS), anthropometric indices, and functional capacity in semi-professional soccer players.
One hundred nine semi-professional male adult soccer players in Tehran were studied. Anthropometric measures, body composition, serum creatine kinase (CK), and lactate dehydrogenase (LDH) were evaluated. Functional capacity was determined using countermovement jump and Queen's College step tests. LCDS was estimated using a validated 168-item food frequency questionnaire for each soccer player.
Mean body mass index (BMI) and fat mass (FM) were 21.86 ± 1.79 kg/m and 10.40 ± 4.11%, respectively, while mean LCDS was found 7.43 ± 2.64. Results of functional performance revealed that mean jump height and maximum oxygen consumption were 37.09 ± 4.92 cm and 59.28 ± 42.8 ml/kg/min, respectively. No significant differences in age or BMI were found among LCDS quartiles. Although mean FM in the lowest quartile of the LCDS was lower compared with other quartiles, the differences in FM and fat-free mass were not significant among LCDS quartiles (p > 0.05). Moreover, we failed to observe any associations between LCDS and body composition or functional performance.
Our results revealed that LCDS was not associated with either body composition or functional capacity in semi-professional male soccer players.

本研究旨在确定半职业足球运动员的低碳水化合物饮食评分（LCDS）、人体测量指标与功能能力之间的联系。
对德黑兰的109名半职业成年男性足球运动员进行了研究。评估了人体测量指标、身体成分、血清肌酸激酶（CK）和乳酸脱氢酶（LDH）。使用反向纵跳和皇后学院台阶试验来确定功能能力。通过一份经过验证的包含168个条目的食物频率问卷对每位足球运动员的LCDS进行评估。
平均体重指数（BMI）和脂肪量（FM）分别为21.86±1.79kg/m²和10.40±4.11%，而平均LCDS为7.43±2.64。功能表现结果显示，平均跳跃高度和最大耗氧量分别为37.09±4.92cm和59.28±42.8ml/kg/min。在LCDS四分位数之间，年龄或BMI没有显著差异。虽然LCDS最低四分位数的平均FM低于其他四分位数，但LCDS四分位数之间的FM和去脂体重差异不显著（p>0.05）。此外，我们未观察到LCDS与身体成分或功能表现之间存在任何关联。
我们的结果表明，LCDS与半职业男性足球运动员的身体成分或功能能力均无关联。
