【摘要】：目的:探討應(yīng)用年齡預(yù)測我國大學(xué)生最大心率(HRmax)的有關(guān)公式及其有效性。方法:研究招募了101名(20.9±1.52歲)大學(xué)生作為測試對象,在運動跑臺上完成逐級遞增負(fù)荷測試(GXT),并獲得實測的最大心率值,另以"220-年齡"、"206.9-0.67×年齡"、"205.8-0.685×年齡"、"210-0.66×年齡"等4個常用公式的計算結(jié)果為預(yù)測值。對測試結(jié)果進(jìn)行統(tǒng)計學(xué)分析。結(jié)果:配對t檢驗與單因素方差分析結(jié)果顯示,"210-0.66×年齡"與實測值沒有顯著性差異(P0.05);Bland-Altman點圖顯示,"210-0.66×年齡"與實測結(jié)果的一致性水平較好。結(jié)論:"210-0.66×年齡"具有可接受的預(yù)測誤差水平,在4個公式當(dāng)中預(yù)測大學(xué)生人群的HRmax準(zhǔn)確性較好。
[Abstract]:Objective: to explore the formula and effectiveness of age prediction of maximum heart rate (HRmax) in Chinese college students. Methods: 101 college students (20.9 鹵1.52 years old) were recruited as subjects. The incremental load test (GXT), was completed on the treadmill and the measured maximum heart rate was obtained, in addition to "220-age". The calculation results of "206.9 鈮，
