【摘要】：目的通過遞增負荷運動實驗(GXT),測試無鍛煉規(guī)律健康成年人的最大心率(HRmax)與無氧閾心率(ATHR),建立最大心率與無氧閾心率推算公式,為在大眾科學(xué)健身中應(yīng)用提供理論依據(jù)和參考。方法以身體健康、無鍛煉規(guī)律的健康成年人665名(年齡20~59歲,其中男性315名,女性350名)為測試對象,采用功率車GXT測試獲得其最大有氧能力測試結(jié)果,運用統(tǒng)計學(xué)方法建立最大心率與無氧閾心率與年齡之間關(guān)系的推算公式;并將GTX實測結(jié)果與目前普遍采用的國外同類的4個最大心率和靶心率推算公式進行對比分析。結(jié)果以最大心率為因變量,年齡為自變量,進行一元線性回歸分析,建立最大心率擬合公式為HRmax=196.86-0.74×年齡(P0.001)。從組內(nèi)相關(guān)系數(shù)來看,GTX最大心率測試值與Fox的最大心率公式計算值之間相關(guān)系數(shù)最高,與Astrand的最大心率公式計算值之間的相關(guān)系數(shù)次之,與Tanaka和Gelish的最大心率公式計算值之間的相關(guān)系數(shù)最低,4組相關(guān)系數(shù)分別為0.76、0.73、0.70、0.70,均介于0.61~0.80,屬于強相關(guān)。以無氧閾心率為因變量,年齡為自變量,進行一元線性回歸分析,建立無氧閾心率擬合公式為ATHR=155.78-0.60×年齡(P0.001);GTX測試無氧閾心率測試值與楊靜宜等的靶心率公式計算值其組內(nèi)相關(guān)系數(shù)為0.60,屬于中等程度相關(guān)。結(jié)論根據(jù)GXT測試結(jié)果擬合的最大心率公式為HRmax=196.86-0.74×年齡,與普遍使用的4個最大心率公式計算值之間存在顯著正相關(guān),但擬合公式最大心率推算結(jié)果均小于這4個推算公式所得到的結(jié)果。通過GXT測試結(jié)果擬合的無氧閾心率公式為ATHR=155.78-0.60×年齡,可以為鍛煉者有氧運動提供有效和可靠的參考依據(jù)。
[Abstract]:Objective to establish a formula for calculating maximal heart rate and anaerobic threshold heart rate (ATHR),) in healthy adults by means of incremental load exercise test (GXT),) to determine the maximum heart rate (HRmax) and anaerobic threshold heart rate (ATHR),). To provide a theoretical basis and reference for the application of mass scientific fitness. Methods 665 healthy adults (20 ~ 59 years old, 315 males and 350 females) were selected as subjects. The results of maximum aerobic capacity test were obtained by power vehicle GXT test. The relationship between maximum heart rate and anaerobic threshold heart rate and age was established by statistical method. The measured results of GTX are compared with the four formulas for calculating the maximum heart rate and the target heart rate of the same kind of foreign countries. Results with the maximum heart rate as the dependent variable and the age as the independent variable, the linear regression analysis was carried out, and the fitting formula of the maximum heart rate was established as HRmax=196.86-0.74 脳 age (P0. 001). From the point of view of intra-group correlation coefficient, the correlation coefficient between GTX maximum heart rate test value and Fox's maximum heart rate formula calculation value was the highest, and the correlation coefficient between Astrand's maximum heart rate formula calculation value and Astrand's maximum heart rate formula value was the second. The correlation coefficient with the maximum heart rate formula of Tanaka and Gelish was the lowest, and the correlation coefficients of the four groups were 0.76 ~ 0.73 ~ 0.70 ~ 0.70 ~ 0.70 respectively, which were between 0.61 and 0.80, which belonged to strong correlation. Taking anaerobic threshold heart rate as dependent variable and age as independent variable, univariate linear regression analysis was carried out, and the fitting formula of anaerobic threshold heart rate was established as ATHR=155.78-0.60 脳 age (P0. 001). The correlation coefficient between the GTX test and the target heart rate formula of Yang Jingyi et al was 0.60, which belongs to the moderate degree. Conclusion the maximum heart rate formula fitted according to the GXT test results is HRmax=196.86-0.74 脳 age, which has a significant positive correlation with the calculated values of the four commonly used maximum heart rate formulas. But the maximum heart rate of the fitting formula is smaller than that of the four formulas. The formula of anaerobic threshold heart rate fitted by GXT test results is ATHR=155.78-0.60 脳 age, which can provide an effective and reliable reference for aerobic exercise of exercisers.
