Brief Summary

The aim of this study is to investigate the anti-exercise-fatigue effects of rice protein RP-80NY in men

Detailed Description

Each subject must undergo a maximum oxygen consumption test 1 week before the intervention (day 1), eat the test food for 28 days (day 1 to day 28), following 14 days of wash-out (day 29 to day 42), and undergo second maximum oxygen consumption test (day 43) and another test food intervention (day 43 to day 70). The assays of anthropometric measurement, diet questionnaire survey, grip strength test and fecal collection were carried out before and after the intervention (the 1st ,28th ,43th and 35th day). Each subject has to join the Wingate anaerobic test (day 21 and day 63), and the endurance exercise test (day 28 and day 70) during the intervention. All of the trial period was 70 days, and the blood samples of the subject will be collected at the times of exercise beginning, 15 min after exercise, the end of exercise, 1 hour after rest, 2 hour after rest ,and 3 hour after rest. During the whole period of participating in the program, blood will be collected 14 times, the blood volume of each times is 10 mL. Gas is collected before the period and within 1 hour, 2 hour and 3 hour after exercise (5 minute at a time). After intervention, the exercise time, oxygen intake, blood biochemical value and gut microbiota will be analyzed.
