3 iii ACKNOWLEDGEMENT I would like to express my heartfelt gratitude to all those who have given me help to complete my master degree study. First of all, I would like to express my sincerest appreciation to Associate Professor Dr. Pratoom Muongmee, my principal advisor, for his support, encouragement, kindness, helping me make my dream come true and providing professional advising, teaching me as a student. I had a difficult time to professional using English but when I approached Dr. Pratoom he was very receptive although he already had a busy schedule. His advising and mentoring was not only through my study process, but also was through the whole graduate years, which was a significant contribution to my academic and professional development. I also greatly appreciate my co-advisor, Associate Professor Dr. Wantana Promsuay for providing excellent suggestions and feedback for the improvement of this study. Secondly, I wish to extend my thanks to Dr. Sukanya Charoenwattana and Dr. Somporn Songtrakul, who were patient to teach me and encourage me for my study. Especially, Dr. Sukanya Charoenwattana not only taught me the knowledge, but also guided me how to be a good graduate student when I couldn t speak English fluently in the first semester. She used to spend a lot of time explaining the details to me again and again. The most important was that she accepted me with her great love. Finally, I should express my gratitude to my family members, my father Li Dingguo and aunty Chen Xiuqin who were supporting me to study and lived in Thailand around three years. Especially, I would like to express my love to my boyfriend, Mr. Fengqin Liu who always teaches me English which help me to improve my English quickly. He taught me how to study and live well as a foreign student. He always stays with me and takes care of me, so that I never feel alone. I love him as he loves me. Li Jia

4 iv : MAJOR: EXERCISE AND SPORT SCIENCE; M.Sc. (EXERCISE AND SPORT SCIENCE) KEYWORDS: VO 2 MAX/ ASTRAND-RHYMING TEST/ YMCA CYCLE ERGOMETER TEST/ COOPER 12 MIN. RUN - WALK TEST/ ROCKPORT FITNESS WALKING TEST/ STEP TEST LI JIA: COMPARISON OF RESULTS OF AEROBIC POWER VALUE DERIVED FROM DIFFERENT MAXIMUM OXYGEN CONSUMPTION TESTING METHODS. ADVISORY COMMITTEE: PRATOOM MUONGMEE, Ph. D., WANTANA PROMSUAY, Ph.D. 83 P This study was conducted to compare the Astrand-Rhyming Test result of VO 2 max value with the test results of YMCA Cycle Ergometer Test, Cooper 12 min. Run-Walk Test, Rockport Fitness Walking Test and Step Test. A total of 20 subjects were purposely selected from volunteer athletes of Burapha University teams in academic year 2011 with average age of ± 0.69 yrs, weight of ± kg and average height of ± 10.01cm. All participants were required to participate in all five tests with 72 hours apart. The data was analyzed paired samples t-test to compare the VO 2 max value of Astrand-Rhyming Test with VO 2 max value obtained from other 4 tests. Results showed that average VO 2 max value (ml/kg/min.) for men and women of YMCA Cycle Ergometer Test (men = ± 8.41, women = ± 6.36), Rockport Fitness Walking Test (men = ± 2.92, women = ± 6.54), Cooper 12 min. Run-Walk Test (men = ± 3.13) and Step Test (men = ± 7.95, women = ± 1.71) were not significantly different from the value obtained from Astrand-Rhyming Test (men = ± 6.90, women = ± 6.14). However, only the VO 2 max value for women from the Cooper 12 min. Run-Walk Test results (women = ± 4.40) was significantly different from Astrand-Rhyming Test (p 0.05). Results suggested that the YMCA Cycle Ergometer Test, Rockport Fitness Walking Test and Step Test, yielding nearest results to the Astrand-Rhyming Test, could be used for field test when the Astrand-Rhyming Test is not suitable.
