我想請問.在體適能檢測中.柔軟度的測量項目.雙腳腳跟須對齊25公分的設限.是否有依據可尋.是如何得知的呢!? 煩請各位先進給小妹解答一下.謝謝!

可能沒有什麼依據吧!?
可有只是想得"正值"吧?!
如果整排數據正負參插
非常不方便
如果有依據
那就是測量結果或經驗得知
25公分差不多就不太會出現負之值
以上屬個人推測

很好的題材耶！我來找找資料。

Abstract ：This study compared the proposed modified sit and reach test (MSR) and the commonly administered sit and reach test (SR) to determine if the MSR can administratively control possible limb-length biases. Subjects (N=258) were administered two trials of each test. The MSR test incorporates a finger-to-box distance (FBD) to account for proportional differences between legs and arms. Individuals with high FBD measurements demonstrated a poorer performance on the SR test. An analysis of the subjects failing to meet the Physical Best standard (25 cm) indicated a higher probability of failure for those with larger FBD scores. The subjects were subsequently separated into three groups: high, medium, and low FBD. There were no significant difference was found on SR performance. The MSR test appears to eliminate the concern of disproportionate limb-length bias expressed by many practitioners.

柔軟度的測量項目
之前常常去幫人家測量體適能，其實我覺得測量坐肢體前彎這一個項目的變數太多了吧！
體前彎的變數有很多，比方說：腹部脂肪囤積、韌帶、肌肉、脊椎椎體的形狀、上臂的長度等。
另外坐肢體前彎測的其實是整個人體後側的整個延展性吧！包含了大腿後側、臀部、背部、肩部、上肢。這些因素都可能影響到測出來的數據，所以我絕得有點部大準。
