This study assessed voluntary dietary intake when different beverages were provided within a recovery area following recreational exercise. Participants completed two 10-km runs 1 week apart. Immediately after the first run, "beer drinkers" (n = 54; mean ± SD: age = 23.9 ± 5.8 years, body mass [BM] = 76 ± 13 kg) randomly received low-alcohol beer (Hahn Ultra® [Lion Co.], 0.9% alcohol by volume) or sports drink (SD; Gatorade® [PepsiCo]), whereas "nonbeer drinkers" (n = 78; age = 21.8 ± 2.2 years, BM = 71 ± 13 kg) received water or SD. Participants remained in a recovery area for 30-60 min with fluid consumption monitored. The following week, participants received the alternate beverage. Participants recorded all food/fluid consumed for the remainder of both trial days (diary and photographs). Fluid balance was assessed via BM change and urine specific gravity. Paired t tests were used to assess differences in hydration and dietary variables. No differences were observed in preexercise urine specific gravity (∼1.01) or BM loss (∼2%) between intervention groups (ps > .05). Water versus SD: No difference in acute fluid intake was noted (water = 751 ± 259 ml, SD = 805 ± 308 ml, p = .157). SD availability influenced total energy and carbohydrate intakes (water = 5.7 ± 2.5 MJ and 151 ± 77 g, SD = 6.5 ± 2.7 MJ and 187 ± 87 g, energy p = .002, carbohydrate p < .001). SD versus beer: SD availability resulted in greater acute fluid intake (SD = 1,047 ± 393 ml, beer = 850 ± 630 ml; p = .004), which remained evident at the end of trial days (SD = 3,337 ± 1,100 ml, beer = 2,982 ± 1,191 ml; p < .01). No differences in dietary variables were observed. Next day, urine specific gravity values were not different between water versus SD. However, a small difference was detected between SD versus beer (SD = 1.021 ± 0.009, beer = 1.016 ± 0.008, p = .002). Consuming calorie-containing drinks postexercise appears to increase daily energy and carbohydrate intake but has minimal impact on next-day hydration.

含卡路里的恢复饮料可以增加休闲跑步者的自愿能量和碳水化合物摄入量，并且对体液恢复的影响最小。

这项研究评估了休闲运动后在康复区内提供不同饮料时自愿饮食的摄入量。参与者相隔1周完成了两次10公里的跑步。首次跑步后，“喝啤酒的人”（n = 54；平均值±SD：年龄= 23.9±5.8岁，体重[BM] = 76±13 kg）随机接受低酒精啤酒（HahnUltra®[Lion Co 。]，酒精含量为0.9％的酒精）或运动饮料（SD；Gatorade®[PepsiCo]），而“非啤酒饮用者”（n = 78；年龄= 21.8±2.2岁，BM = 71±13 kg）接受水或SD 。参与者在恢复区停留30-60分钟，并监测液体消耗。接下来的一周，参与者收到了替代饮料。参与者记录了在两个试验日的剩余时间内消耗的所有食物/流体（日记和照片）。通过BM变化和尿比重评估体液平衡。配对的t检验用于评估水分和饮食变量的差异。干预组之间的运动前尿比重（〜1.01）或BM损失（〜2％）没有观察到差异（ps> .05）。水与SD：急性液体摄入量没有差异（水= 751±259 ml，SD = 805±308 ml，p = .157）。SD的可用性会影响总能量和碳水化合物的摄入量（水= 5.7±2.5 MJ和151±77 g，SD = 6.5±2.7 MJ和187±87 g，能量p = .002，碳水化合物p <.001）。SD与啤酒：SD的可获得性导致更多的急性体液摄入（SD = 1,047±393 ml，啤酒= 850±630 ml； p = .004），在试验结束时仍很明显（SD = 3,337±1,100 ml，啤酒= 2,982±1,191毫升； p <0.01）。没有观察到饮食变量的差异。第二天，水与标清之间的尿比重值没有差异。但是，在SD与啤酒之间检测到很小的差异（SD = 1.021±0.009，啤酒= 1.016±0.008，p = .002）。运动后食用含卡路里的饮料似乎可以增加每日的能量和碳水化合物的摄入量，但对第二天的水合作用影响最小。
