A well-balanced diet is one of the main factors that may play a supportive role in enhancing acute training stimuli in optimal training adaptation. The aim of the present study was to examine the energy and macro- and micronutrient intake including and excluding supplements among top-level Polish football players during one week of the general preparatory period. In addition, the study looked at whether athletes consume carbohydrates in recommended amounts, depending on the completed training sessions. A total of 26 professional football players were included in the study. The preseason dietary intake was assessed using a 7-day estimated food record. The energy value of the diet and the amounts of the dietary ingredients were assessed using the software Dieta 6.0. The average consumption of energy, vitamin B, vitamin C, vitamin E, folate, and calcium was lower than recommendations, and average intake of sodium and potassium was higher than the norm in the diets of the athletes. The results of this study do not confirm the justification for adding protein preparations to diets of the studied players. Furthermore, football players dietary carbohydrate intake was relatively low in comparison to requirements based on training loads. Based on our results we conclude that further work is necessary to reinforce education about nutritional habits and adjust nutritional strategies to individual needs to enhance athletic performance.
均衡的饮食是支持增强急性训练刺激以达到最佳训练适应的主要因素之一。本研究的目的是在一般准备期的一周内检查顶级波兰足球运动员的能量和宏量及微量营养素摄入,包括和不包括补充剂。此外,研究还观察了运动员是否根据完成的训练量摄入推荐量的碳水化合物。共有 26 名职业足球运动员参与了这项研究。使用 7 天估计食物记录来评估赛前饮食摄入。使用软件 Dieta 6.0 评估饮食的能量值和饮食成分的量。运动员饮食中维生素 B、维生素 C、维生素 E、叶酸和钙的平均消耗量低于建议量,而钠和钾的平均摄入量高于正常水平。这项研究的结果并不能证明在研究对象的饮食中添加蛋白质制剂是合理的。此外,与基于训练负荷的需求相比,足球运动员的饮食碳水化合物摄入相对较低。基于我们的结果,我们得出结论,需要进一步加强关于营养习惯的教育,并根据个人需求调整营养策略,以提高运动表现。
