摘要

划船技术是决定运动成绩好坏的主要因素之一。在赛艇运动中,许多不同的因素结合在一起,但只有理解了有效的技术,掌握了关键因素,赛艇运动员才能从训练中获得充分的好处。当前研究的主要目的是确定BioRow技术系统用于训练大学生-新手赛艇运动员后对某些技术指标的影响。实验方法包括三个变量的测量:手柄、座椅和躯干的位置(肩关节水平)。腿、躯干和手臂的速度由测量点得出并用于分析。BioRow技术系统产生三个即时显示的指标,供桨手查看:捕捉因素,划船风格因素和完成因素。桨手每次划桨后都会收到实时反馈。收到的结果表明,在所调查的学生群体中,上述所有指标都有所增加。结果表明,在不同强度划船时,Catch因子增加,平均d%=75.17, P(t) = 86.6;赛艇风格因子d%=23.25, P(t) = 95.7,终点因子d%=33.86, P(t) = 68.3。分析结果表明,对提高赛艇划桨技术指标有积极作用。在测力计上使用BioRow技术系统可以减少新手划船运动员通常需要提高划船技术的时间。

STUDY ON THE EFFECT OF USING BIOROW TECH SYSTEM FOR IMPROVING SOME TECHNICAL INDICATORS OF THE ROWING STROKE WITH NOVICE ROWERS
ABSTRACT The rowing technique is one of the main factors determining good sports results. Many different factors are combined in rowing, but only if the effective technique is understood and its key factors are mastered the rowers would be able to realize the full benefit from training. The primary purpose of the current research was to determine the effect on some technical indicators after the BioRow Tech system for ergometers was used in training university students – novice rowers. Methods of the experiment include measuring three variables: the positions of the handle, seat and trunk (at the level of the shoulder joint). The velocities of the legs, trunk, and arms were derived from measured points and used for analyses. BioRow Tech system produces three indicators displayed instantly for the rower to see: Catch Factor, Rowing Style Factor, and Finish Factor. Rowers receive real-time feedback after each stroke. The received results demonstrate an increase in all the above indicators within the groups of investigated students. It was determined that when rowing with different intensities, the Catch factor increased with an average of d%=75.17, P(t) = 86.6; the Rowing Style Factor with d%=23.25, P(t) = 95.7, and the Finish Factor with d%=33.86, P(t) = 68.3. The analysis of the results reveals a positive effect on improving the rowing stroke technical indicators. Using the BioRow Tech system on an ergometer could cut down the time novice rowers typically need to improve their rowing technique.
