Functional Food Application of Okara Protein Hydrolysate (OPH)- for Anti-exercise-fatigue

Study Overview
=================
Brief Summary
-----------------
The aim of this study is to investigate the anti-exercise-fatigue effects of okara protein hydrolysate (OPH) in men

Detailed Description
-----------------
Each subject must undergo a cardiopulmonary capacity test to assess the maximum oxygen uptake 1 week before the intervention (day 1), and then eat the test food for 4 weeks (day 8 to day 35). Before and after the intervention (the 8th and 35th day), posture measurement, diet questionnaire survey and endurance exercise ability test were carried out. The trial period was 35 days. The subjects will take blood samples before, during, after, and 30 minutes and 60 minutes after the end of the two endurance exercise tests. During the whole period of participating in the program, blood will be collected 10 times, each with a blood volume of 15 mL. Gas is collected during the period and within 1 hour after exercise. Gas is collected every 15 minutes and 1 minute at a time. Analyze his exercise time, oxygen intake and blood biochemical value.
