我們將藉由回顧歷來研究以審視。一次反覆最大肌力（One-repetition maximum，簡稱1RM）且利用於不同人群的預測公式的發展。已知，1RM的測量百分比（%1RM）和預測1RM，在不同人群之間有不同的預測公式。例如，1RM的訓練與自覺量表（RPE）未經訓練的受測者與受過訓練者有所不同。且由於RM減小，重複會減少；而比較男、女的1RM與%1RM所測得的力量在男性比女性更大。1RM的不同的強度測試也可以觀察到不同的預測公式：不只在不同的運動類型的測試可以觀察到不同的預估公式，也可運用於不同年齡層之肌力發展。例如：健力運動員、足球運動員、籃球運動員、男性與女性甚至一般人。綜合上述，一個多RM預測公式的發展取決於性別、年齡、運動的類型和肌力活動水準。在未來，我們將發展更具體的預測公式，運用在不同的的運動類型與各種不同的族群。

The purpose of the article was to review the studies of predictive equations of One Repetition Maximum (1RM) in various populations. It is well known that the prediction of 1RM from multiple RM varies among different populations. For example, the relationship between Rating of Perceived Exertion (RPE) and 1RM is quite different in trained population and untrained population. As the 1RM decreases, the repetition decreases. Comparing male and female, strength testing through 1RM and %1RM are greater in male. Different predictive equations also exist when testing 1RM from different intensities. Different predictive equations also exist among athletes from different sports such as power lifting, football, basketball, male, female and even general population and different age groups. In summary, the development of predictive equations of One Repetition Maximum depends on the gender, age, types of sport and level of physical activity. In the future, specific predictive equations for different sport and different population should be developed.
