This sutdy was attempted to investigate the effect of amount and ingestion time of citric acid recovery rate of heart rate before and mid-exercise. Citric acid ingested 0g, 3.5g, 5g, 7.5g, and 10g before exercise(90min, 75min, and 60min) and mid-exerc...
This sutdy was attempted to investigate the effect of amount and ingestion time of citric acid recovery rate of heart rate before and mid-exercise. Citric acid ingested 0g, 3.5g, 5g, 7.5g, and 10g before exercise(90min, 75min, and 60min) and mid-exercise(0min, 5min, 10min, 15min, and 20min). The subjects were 9 high school students.
The rate of heart rate was recovered fast when 5g and 3.5g of citric acid was ingested at 75 min 60min before exercise, respectively. However, the recovery of heart rate was best when 5g of cifacid was added at 15min and 20min during exercise. The effect of citric acid was better when ingested before rather than during.
