我们通过比较新手和有经验的青少年射箭运动员在射箭比赛中心率变异性的变化以及射箭表现来评估自主神经系统的调节。7名新手（年龄14.0 ± 8.5岁，身体质量指数22.9 ± 4.3kg中心点m-2，训练经验0.4 ± 0.3年）和10名有经验的弓箭手（年龄16.5 ± 10.3岁，身体质量指数22.4 ± 3.1kg中心点m-2，训练经验4.1 ± 0.9年）自愿参加。在两轮比赛中，使用逐搏心率监测，在每次射箭前20 s测量心率变异性。我们发现，与新手相比，有经验的青少年射箭运动员：（i）每次射击花费更多的时间;（ii）具有更高的低频带，连续R-R间期之间的平方差的平方根（即心电图中两个连续R波之间经过的时间），以及连续正常到正常间期大于50 ms的百分比;和（iii）与赛前值相比，显示出副交感神经系统活动的增加。我们建议，这些特点的经验丰富的弓箭手是适当的最佳性能在比赛中。
We assessed autonomic nervous system modulation through changes in heart rate variability during an archery competition as well as archery performance by comparing novice and experienced adolescent archers. Seven novice (age 14.0 +/- 8.5 years, body mass index 22.9 +/- 4.3kg center dot m-2, training experience 0.4 +/- 0.3 years) and ten experienced archers (age 16.5 +/- 10.3 years, body mass index 22.4 +/- 3.1kg center dot m-2, training experience 4.1 +/- 0.9 years) volunteered. Using beat-by-beat heart rate monitoring, heart rate variability was measured for 20s before each arrow shot during two rounds of competition. We found that, compared with novices, experienced adolescent archers: (i) take more time per shot; (ii) have a higher low frequency band, square root of the mean of squared differences between successive R-R intervals (i.e. the time elapsing between two consecutive R waves in the electrocardiogram), and percentage of successive normal-to-normal intervals greater than 50ms; and (iii) demonstrate an increase in parasympathetic nervous system activity compared with pre-competition values. We propose that these characteristics of experienced archers are appropriate for optimal performance during competition.
