This study aims to investigate the correlation between the 2.4 km Run-Walk Test and the Multi-stage Fitness Test (MST) in measuring aerobic fitness in the National Physical Fitness Award (NAPFA) of Secondary 2 students in Singapore. 187 Secondary 2 students (age 14 years) of a mixed gender secondary school were recruited for the study. Subjects performed the 2.4 km Run-Walk Test and the MST. The VO2 max level obtained from both tests were compared using the Pearson correlation coefficient analysis and Paired-sample t-test. Pearson correlation coefficient analysis shows that the predicted VO2 max from the two tests share a strong positive correlation with r=0.78. However, Paired-sample t-test shows that VO2 max predicted by the 2.4 km Run-Walk test is significantly (t = 13.82, p < 0.05) greater (mean = 36.70 L/min, SD = 4.32) than that predicted by MST (mean = 33.60 L/min, SD = 4.91). Results of the present study suggest that both the MST and 2.4 km Run-Walk test can measure aerobic fitness of 14-year old participants for NAPFA. In unfavourable weather, the MST can replace the 2.4 km Run-Walk Test. Further research can be done to enhance the test setting and environmental factors, as well as to include subjects of other age groups and ethnicities, to obtain a more holistic perspective on the interchangeability of the two tests for NAPFA assessment.

本文旨在探討2.4公里耐力跑與20米每分鐘遞增速度往返跑測驗(簡稱20米往返跑)在新加坡全國體能測驗中測試中二學生 心肺功能的關係。本研究對187名男女同校的中二學生(14歲)進行2.4公里耐力跑與20米往返跑。接著，從這兩項測驗中預測 學生最大吸氧量，採用積差相關係數與相依樣本T鑒定進行檢驗。積差相關係數顯示2.4 公里耐力跑與20米往返跑預測的最大 吸氧量正相關(r=0.78)。相依樣本T鑒定顯示2.4公里耐力跑預測的最大吸氧量顯然(t=13.82,p<0.05) 高於(mean=36.70 L/min, SD=4.32)20米往返跑預測的最大吸氧量 (mean=33.60 L/min, SD=4.91)。研究結果顯示，2.4公里耐力跑與20米往返跑可用於新 加坡全國體能測驗，是測試新加坡中二學生心肺功能的可靠方法。若天氣不佳，20米往返跑可取代2.4公里耐力跑。為了在現有 的基礎上加強實驗的整體設定，以及減少環境因素造成的影響，可以進行更深入調查。其外，也可以從不同年齡和種族背景方面 擴大研究物件，從一個更全面的角度研究並分析這兩種測驗在新加坡全國體能測驗的可替換性。
