Abstract

BackgroundHeart rate value during different phases of archery shooting has been correlated with performance scores.ObjectivesThis study was done to ascertain this and with an aim of real-time objective field assessment of training and performance among Elite Indian archers.MethodsThe study was conducted in Indoor archery hall as per World Archery Association rules with Cross-sectional study design. Seven volunteered male elite archers (mean age: 23.9 ± 3.00 years, mean experience: 8.5 ± 2.35 years) shot 30 arrows each (n = 210) with simultaneous recording of heart rate, score and shooting action. Release frames were identified by slow motion analysis. Heart rate values during release (0 s), every second for 5 seconds before and after the release of arrow were noted and analyzed. One-way ANOVA test was employed. Level of significance was set at P < 0.05.ResultsOne-way ANOVA of heart rate values at all 11 time-points between the three scores 8, 9 and 10 showed significant differences from -5 s to -1 s with heart rate values at score 8 being significantly higher (P < 0.05). Heart rate decreased significantly from -5 s to +1 s and increased further.ConclusionsHeart rate deceleration was found in aiming and release phases of shooting. The elicited change in trend of the heart rate values can be used as a field-tool for training archers. Future studies on novice archers would help us understand the change in trend with training and experience in the sports.

射击时的心率值是射箭场上的表现分析工具——对印度优秀射手的研究

研究背景:射箭运动中不同阶段的心率值与运动成绩之间存在相关性。本研究是为了确定这一点，目的是对印度优秀弓箭手的训练和表现进行实时客观的实地评估。方法按照世界射箭协会规定，采用横断面研究设计，在室内射箭馆进行研究。7名志愿男性优秀弓箭手(平均年龄23.9±3.00岁，平均经验8.5±2.35岁)每人射箭30支(n = 210)，同时记录心率、得分和射击动作。通过慢动作分析确定释放帧。记录并分析释放期间(0秒)、释放前后5秒内每秒钟的心率值。采用单因素方差分析检验。P < 0.05为显著性水平。结果8、9、10分11个时间点心率值的单因素方差分析显示，-5 s与-1 s之间存在显著差异，8分心率值显著高于-1 s (P < 0.05)。心率从-5秒明显下降到+1秒，并进一步增加。结论在射击的瞄准和释放阶段均存在心率减慢现象。由此得出的心率值变化趋势可以作为训练射箭运动员的野外工具。未来对新手射箭运动员的研究将有助于我们了解随着训练和运动经验的变化趋势。
