The Effects of Fasting Program using Rezen on Improvemnet of Fatigue of Freedivers

Objectives We conducted a survey to investigate the fasting program using Rezen is effective for freediving. Methods A survey was conducted before and after the freediving fasting program for 15 participants. Participants were athletes who participated in a freediving competition held in Cebu Mactan, Philippines. A structured questionnaire of freediving fasting program was distributed to responders and all data were statistically analyzed. Results All respondents were freediving intermediate or higher, and 9 out of 15 were instructors. There was no significant difference in the results of the subjective symptom questionnaire to check the side effects of the fasting program. As a result of revised Chalder’s fatigue scale, there was a significant improvement in 6 items of alertness, motivation, energy, muscle strength, physical strength, and concentration among 11 items, and the total score was improved from 24.60±4.42 to 18.87±5.17, which was significantly improved by 5.73±5.34 points. As a result of the taste evaluation of Rezen, 6 people responded ‘Excellent’, 4 people responded ‘good’, 3 people responded ‘average’, and 2 people responded ‘Below average’. When asked whether the fasting program was helpful to freediving, 1 people responded ‘Extremely helpful’, 7 people responded ‘Very helpful’, 4 people responded ‘Somewhat helpful’, 1 people responded ‘Not so helpful’, and 1 people responded ‘Not at all’. Conclusions The possibility that the fasting program using Rezen could be effective for freediving by improving fatigue was confirmed, and the potential of Rezen as a sports drink was improved.
