　The current study examined subjective fatigue and sports performance while consuming a supplement with antioxidant action for 30 d. A questionnaire to gauge fatigue was administered prior to the study, 1 wk after its start, 2 wk after its start, 3 wk after its start, and upon conclusion of the study. One group of participants included 6 male college triathletes who routinely exercised by swimming for 2 hr 5 times a wk, biking for 4 hr once a wk, and running for about 3 hr 3 times a wk. Results indicated statistical improvement in fatigue, the legs, the torso, physical recovery, the lower back, the knees, the hips, the back, and the shoulders. In addition, participants completed a 400-m swim before and after the study. Results indicated that performance on the swim improved significantly (p<0.01)．Moreover, the total score for fatigue was 47.7 points after the study versus 35.6 beforehand, so fatigue improved significantly (p<0.01)．A second group of participants included 5 track and field athletes who routinely exercised 2 to 3 hr 5 times a wk. Their fatigue improved significantly (p<0.05)， as indicated by values before and after the study. These findings indicate that the “antioxidant action” of astaxanthin may actually involve antioxidant action, anti-fatigue action, antiinflammatory action, enhanced immunity, and enhanced endurance. Moreover, the supplement’s 2 actions, “production of energy” by reduced coenzyme Q10 and “antioxidant action” that inhibited physical deterioration, may have led to improved performance. Furthermore, leucine may have augmented muscle protein synthesis. Two amino acids, leucine and arginine, efficiently produce energy through the citric acid cycle (a system for energy metabolism) and hasten recovery from fatigue. Thus, the supplement may have helped athletes engaged in strenuous training like that in this study to recover from fatigue. Citrulline is a vasodilator that improves sports performance, and citrulline presumably helped participants improve their time on the 400-m swim. An essential fatty acid (an ω 3 polyunsaturated fatty acid)， DHA in phospholipid form is taken up by the cell membrane. DHA enhances cell and tissue function in the body by prompting cells to take up nutrients and quickly eliminate waste products, and DHA presumably helps the body to recover from fatigue., application/pdf},
