【摘要】：目的:本研究評估了不同力量訓(xùn)練方案對心臟自主神經(jīng)功能產(chǎn)生的影響。方法:研究采用隨機(jī)交互式的設(shè)計,20名健康男性受試者完成3次不同方案的力量訓(xùn)練,分別記錄R-R間期:包括安靜狀態(tài)5min(臥位),整個力量訓(xùn)練期間,訓(xùn)練后恢復(fù)期5min(臥位),進(jìn)行相應(yīng)心率變異(HRV)分析,并分別進(jìn)行血乳酸檢測。結(jié)果:三種力量訓(xùn)練方案運(yùn)動期及恢復(fù)期心臟的自主神經(jīng)功能發(fā)生不同的調(diào)整。肌肉耐力訓(xùn)練方案(ME)和肌肉肥大訓(xùn)練方案(MH)心臟自主應(yīng)答基本趨于一致,但肌肉最大力量訓(xùn)練方案(MM)在整個運(yùn)動期間心率(HR)指標(biāo)低于ME和MH(P0.05),運(yùn)動中全部NN間期的標(biāo)準(zhǔn)差(SDNN)和心率變異性系數(shù)(SDNN/HR)指標(biāo)略高于方案ME和MH,5min恢復(fù)期高低頻比值(LF/HF)指標(biāo)趨于安靜狀態(tài)。此外,運(yùn)動后即刻MM血乳酸的濃度顯著低于方案ME和MH(P0.05)。結(jié)論:方案MM在整個運(yùn)動中交感活性程度相對增加,恢復(fù)期交感活性回落較快,表明不同力量訓(xùn)練方案對心臟自主神經(jīng)功能產(chǎn)生影響存在差異,并可能對心臟的健康產(chǎn)生不同的影響。
[Abstract]:Objective: to evaluate the effects of different strength training programs on cardiac autonomic nervous function. Methods: a randomized and interactive design of 20 healthy male subjects was used to complete three different strength training sessions. R-R intervals were recorded for 5 mins, including rest status, during the whole strength training period. The HRV and blood lactic acid were measured at 5 mins after training. Results: the cardiac autonomic nervous function of the three kinds of strength training programs were adjusted differently during exercise and convalescence. The cardiac autonomic response of muscle endurance training program (MEM) and muscle hypertrophy training program (MH) was similar. However, during the whole exercise period, the HRI of the maximal muscle strength training regimen (MMM) was lower than that of ME and MHN P0.05G, and the standard deviation of all NN intervals and the heart rate variability coefficient (HRR) were slightly higher than those of the scheme ME and MHN 5min recovery phase LFP / HFR). Indicators tend to be quiet. In addition, immediately after exercise, the serum lactate concentration of MM was significantly lower than that of ME and MHG P 0.05. Conclusion: the degree of sympathetic activity of scheme MM increased relatively during the whole exercise, and the sympathetic activity decreased rapidly during the recovery period, which indicated that different strength training schemes had different effects on cardiac autonomic nervous function. And may have different effects on heart health.
