Exercise could influence energy and macronutrient intake, which could have an important role on body composition changes in response to exercise. The present study aimed to investigate the effects of different training modalities in energy and macronutrient intake, and whether changes in energy and macronutrient intake influences changes in body composition in response to different training modalities.
A 12-week randomised controlled trial was conducted. Eighty middle-aged sedentary adults were randomised to: (i) a control group; (ii) physical activity recommendation from the World Health Organization; (iii) high-intensity interval training; and (iv) whole-body electromyostimulation training. Dietary intake was assessed using the average of three 24-h recalls.
High-intensity interval training and whole-body electromyostimulation training groups showed lower fibre intake and higher dietary energy density. Our results showed a negative association was found between changes in energy intake and changes in lean mass index. No association was found between changes in protein intake and changes in lean mass index.
In conclusion, we observed a higher dietary energy density and lower fibre intake in high-intensity training groups.
运动可影响能量和常量营养素的摄入，这可能在运动引起的身体成分变化中发挥重要作用。本研究旨在调查不同训练方式对能量和常量营养素摄入的影响，以及能量和常量营养素摄入的变化是否会影响不同训练方式下身体成分的变化。
进行了一项为期12周的随机对照试验。80名中年久坐不动的成年人被随机分为：（i）对照组；（ii）世界卫生组织的身体活动建议组；（iii）高强度间歇训练组；（iv）全身肌电刺激训练组。使用三次24小时回忆的平均值评估饮食摄入量。
高强度间歇训练组和全身肌电刺激训练组的纤维摄入量较低，饮食能量密度较高。我们的结果表明，能量摄入变化与瘦体重指数变化之间存在负相关。蛋白质摄入变化与瘦体重指数变化之间未发现相关性。
总之，我们观察到高强度训练组的饮食能量密度较高，纤维摄入量较低。
