熱環境中運動員訓練後脫水情形與實際的液體補充會影響其運動表現與生理恢復速度。為了解運動員在熱環境中參與足球訓練時，接受特定液體攝取方案對其身體水分變化之影響，乃針對18位優秀男子足球運動員（年齡：21.70±1.20歲；身高：175.70±6.50公分；體重：70.00±4.60公斤），令其在熱環境中（溫度：31.28±1.63℃；相對濕度：71.00±4.85%）完成20分鐘的熱身及90分鐘的足球訓練。訓練期間接受設定之液體攝取方案「訓練前、中場休息及訓練後，攝取10至15°C的運動飲料(1300 ml)與飲用水(500 ml)」。監測受試者的體重、心跳率(n=4)以及排尿量，並於訓練後立即填寫腸胃感覺狀態表。結果發現：訓練過程中受試者均未排尿，心跳率為152±12 bpm。訓練後體重減少0.98±0.42 kg(0.34-1.68 kg)，經計算脫水程度1.40±0.62% (0.50-2.49%)、流汗量2.78±0.42升（2.14-3.48升）、流汗率1.39±0.21 l/h (1.07-1.74 l/h)，亦無腸胃不適報告。綜合上述結果，本研究所設定之水分攝取方案可減輕足球運動員在熱環境下運動所導致的脫水程度。

Dehydration level and fluid ingestion can highly affect the physical recovery rate and sport performance of athletes worked in hot environment. The present study was conducted to clarify the rehydration effect of a fluid ingestion protocol on soccer players trained in a hot and humid environment (31.28±1.63℃; relative humidity, 71.00±4.85%). Eighteen elite male soccer players were recruited in this study (21.70±1.20 years-old, 175.70±6.50 cm, 70.00±4.60 kg). The training course included a 20-min warm-up and 90-min soccer training, besides, the strength was set as high as a formal game. According with the training program, a fluid prescription, including tapping water (500 ml, 15℃) and sport drink (1300 ml, 15℃) was conducted. The weight, pulse rate (n=4), and urine discharge amount are monitored, and the form for the feelings of stomach and intestines is filled at once. The results are: the subjects do not discharge the urine and the pulse rate is 152±12 bpm during training; 0.98±0.42 kg (0.34-1.68 kg) of weight is reduced after training; the dehydration is 1.40±0.62% (0.50-2.49%); the sweat amount is 2.78±0.421l (2.14-3.481); the sweat rate is 1.39±0.21l/h (1.07-1.74l/h); and no uncomfortable stomach and intestines is reported after training. In summary, the proposed fluid ingestion protocol can protect soccer players trained in hot environment from severe dehydration.
