Technical Analysis and Training Approaches for Group A Difficulty in Artistic Aerobics——Sharp Angle Support Rotation 720 Degrees(A249)
A249 is a difficulty commonly employed by female athletes in artistic aerobics-the sharp angle support rotation 720 degrees,falling under the static strength category within the A group difficulty,demanding elevated physical fitness from participants.This study utilizes diverse research methods such as literature review,video observation,mathematical statistics,and logical analysis to scrutinize completion standards,technical nuances,athlete utilization,competitive performance,common errors,and training methods associated with this difficulty.The objective is to aid Chinese female athletes in swiftly grasping the technical essentials of this maneuver and offer a reference for experts and scholars exploring the intricacies and training methods of this highly challenging movement.Our findings reveal:(1)The prerequisites for accomplishing the A249 difficulty include:throughout the rotation process,the body,excluding the arms,must avoid contact with the ground,legs should achieve at least a vertical angle to the ground,and no more than 8 hand exchanges.(2)The A Group difficulty,Sharp Angle Support Rotation 720 Degrees,currently stands as a frequently employed high-difficulty maneuver among female athletes in both domestic and international artistic aerobics competitions.It ranks as the highest-scoring difficulty movement in the static strength category for female solo athletes in the A group difficulty,commonly integrated into routines by outstanding female athletes domestically and internationally.(3)The prevalence of the A249 difficulty in international competitions surpasses that in domestic artistic aerobics contests.In international competitions,female solo athletes execute this difficulty with superior quality,while the quality of execution by Chinese female athletes requires enhancement.(4)Chinese female athletes often encounter challenges in synchronizing hand exchanges or experience excessively large hand exchange amplitudes during the rotation process,leading to frequent failures in executing the movement.
