目的:探讨不同最大摄氧量人群对定量运动后心率恢复的影响。方法:选取体育学院23名本科生为受试对象,平均年龄为19.17±0.83岁。Astrand-Ryhming列线图法测试个体最大摄氧量(VO2max),并根据VO2max不同分为两组:低VO2max组(A组)和高VO2max组(B组),使两组间个体VO2max具有明显差异(P<0.01)。之后所有受试者进行5min台阶测试,分别测试运动后即刻、30s、1min、2min、3min、4min心率。结果:(1)A、B两组安静心率无明显差异(P>0.05);(2)运动后即刻和运动后30s,A组心率均明显高于B组(P<0.01,P<0.05);运动后1min、2min、3min、4min不同摄氧量水平之间心率均无明显差异(P>0.05);(3)运动后1min,A、B两组间心率恢复无明显差异(P>0.05)。结论:(1)体育专业本科生个体VO2max水平越高,其心率储备能力越强;(2)定量运动负荷后,心率恢复与个体VO2max水平无关。
Objective: To investigate the effect of different maximal oxygen uptake population on heart rate recovery after quantitative exercise. Methods: Twenty-three college undergraduates of Physical Education Institute were chosen as subjects, with an average age of 19.17 ± 0.83 years. Astrand-Ryhming collinear method was used to test the maximal oxygen uptake (VO2max) of subjects and divided into two groups according to VO2max: low VO2max group (group A) and high VO2max group (group B) Difference (P <0.01). Afterwards, all the subjects were tested for 5min steps, and were tested immediately after exercise, 30s, 1min, 2min, 3min, 4min heart rate. Results: (1) There was no significant difference in resting heart rate between groups A and B (P> 0.05). (2) The heart rate of group A was significantly higher than that of group B immediately after exercise and 30s after exercise (P <0.01, P < (P> 0.05); (1) There was no significant difference in heart rate recovery between groups A and B at 1 min after exercise (P> 0.05) ). Conclusions: (1) The higher the VO2max level of undergraduates, the stronger their heart rate reserve ability. (2) The recovery of heart rate has nothing to do with the level of VO2max after the quantitative exercise load.
