不同階高對三分鐘登階測驗體能指數之影響
Physical Efficiency Index of Different Step Height in Three Minutes Step Test
摘要
本研究探討階高對登階測驗之體能指數的差異情形。將受試者依身高分為三組(159-168公分、169-178公分、179-188公分)，每組各10人，所有受試者均進行35公分階高與調整階高(脛骨粗隆高度)之三分鐘登階測驗。以新華電腦公司所產之i-FITT-HRM2儀器監測心率變化並將資料以平均值等式穩健測試以及成對樣本t檢定進行統計處理以探討其差異情形。研究結果為一、不同身高在35公分階高之體能指數未達顯著差異(p＞.01)。二、不同身高在調整階高之體能指數未達顯著差異(p＞.01)。三、不同身高在調整階高之體能指數表現均低於35公分階高之體能指數表現，其中以169-178公分及179-188公分具有顯著差異(p＜.01)。本研究認為身高介於159-168公分之組別以35公分階高以及以脛骨粗隆高度調整之階高進行三分鐘登階測驗均無顯著差異，因此目前標準三分鐘登階測試35公分之階高對於身高介於159-168公分之受試者可以體能指數測得其心肺適能。但對於其他兩組研究結果顯示以脛骨粗隆高度調整之階高與35公分之階高比較具有顯著差異，且體能指數均有下降之情形，其合適之登階高度有待進一步之探討。

The primary objective of this study was to investigate the effects of step height on the Physical Efficiency Index (PEI) of a three-minute step test. The subjects were divided into three groups according to their heights (159-168 cm, 169-178 cm, and 179-188 cm), with 10 subjects in each group. All the subjects performed the three-minute step test with two different step heights (a 35 cm step height and a step height adjusted to the height of the tibial tuberosity). The i-FITT-HRM2 instrument developed by Microtime Computer Inc. was used to monitor the subject’s heart rate variation. Data were analyzed using Welch/ Brown Forsythe test and paired sample t-tests to investigate the effects caused by the difference in step height. The results were followed: (1) There was no significant difference in the PEI in the three-minute step test performed at the 35 cm step height (p＞.01). (2) There was also no significant difference in the PEI in the three-minute step test performed at the adjusted step height (p＞.01). (3) Subjects in all three groups exhibited lower PEIs when undergoing the three-minute step test performed at the adjusted step height compared to that at the 35 cm step height, where the 169-178 cm group and the 179-188 cm group exhibited significant differences in this respect (p ＜.01). The conclusion of this study were that the group of subjects with body heights between 159 cm and 168 cm demonstrated no significant difference after undergoing the three-minute step test at a step height of 35 cm and a step height adjusted to the height of the tibial tuberosity. Hence, it is believed that the test performed at a 35 cm step height is suitable for subjects with body heights between 159 cm and 168 cm. The other two groups exhibited significant differences between the three-minute step tests performed at the 35 cm step height and the adjusted step height, i.e., a decline in PEI after step height adjustment. Therefore, the appropriate step height for these two groups of subjects requires further investigation.
