This study aimed to evaluate the effects of compact food bar (CFB) designed on cardiopulmonary function in men athletes who serve in military service.
In this randomized, single-blind, controlled clinical trial, 46 men of military staff were arranged into 2 groups and studied for 28 days; one branch used 3 packs daily, 700 kcal each, of CFB with Functional compounds (Caffeine and L-arginine) and the other group used regular food during training course. Maximal oxygen uptake (VO Max) with cardiopulmonary exercise test, body composition, and physical activity were assessed and recorded at baseline and end of the study period.
VO Max ( = 0.05) significantly increased in CFB group compared with baseline. Moreover, VO Max ( = 0.01), VO/HR ( = 0.04), oxygen uptake/heart rate (VO/HR) ( = 0.03), and ventilation per minute/oxygen uptake (VE/VO) ( = 0.03) significantly increased in CFB group compared with control group. In comparison, there was no significant difference in mean ventilation per minute/carbon dioxide production (VE/VCO) ( = 0.41), ventilation per minute (VE) ( = 0.69), and breathing frequency ( = 0.056). No significant effect of CFB was found on weight, body mass index ( = 0.23), lean body mass ( = 0.91), and body fat mass ( = 0.91).
Our results show that intervention with CFB is more effective than regular diet in improving cardiopulmonary function in men athletes who serve in military service.
本研究旨在评估专为服兵役的男性运动员设计的紧凑型食品棒（CFB）对心肺功能的影响。
在这项随机、单盲、对照临床试验中，46名军事人员被分为两组，研究为期28天；一组每天使用3包，每包700千卡，含有功能性化合物（咖啡因和L-精氨酸）的CFB，另一组在训练期间使用常规食物。在基线和研究期末评估并记录心肺运动试验中的最大摄氧量（VO₂max）、身体成分和身体活动情况。
与基线相比，CFB组的VO₂max（P = 0.05）显著增加。此外，与对照组相比，CFB组的VO₂max（P = 0.01）、VO₂/心率（VO₂/HR）（P = 0.04）、摄氧量/心率（VO₂/HR）（P = 0.03）和每分钟通气量/摄氧量（VE/VO₂）（P = 0.03）显著增加。相比之下，每分钟平均通气量/二氧化碳产生量（VE/VCO₂）（P = 0.41）、每分钟通气量（VE）（P = 0.69）和呼吸频率（P = 0.056）没有显著差异。未发现CFB对体重、体重指数（P = 0.23）、瘦体重（P = 0.91）和体脂肪量（P = 0.91）有显著影响。
我们的结果表明，对于服兵役的男性运动员，CFB干预在改善心肺功能方面比常规饮食更有效。
