Research On The Motion Characteristics Of Water Resistance Rowing Machine

In order to explore the movement characteristics of the body parts of the water resistance rowing machine during the paddle pulling stage,the kinematics characteristics and muscle force characteristics of the rowing stage of the water blocking rowing device are analyzed by motion capture.This paper selected 6 male adolescent rowing athletes and 6 ordinary students as the experimental object,the young men rowing athletes and ordinary athletes in the water resistance of rowing oars technique were analyzed from the perspective of three-dimensional boating,synchronous analysis method using 3D motion capture system and surface EMG acquisition system,rowing oars action of every part of the body kinematics parameters and original emg.This paper analyzes and discusses the influence of water resistance rowing device on the indexes of movement and posture and muscle force,and then compares the characteristics of different wind resistance rowing machines in the field of professional training.Research shows that in resistance characteristics,the joint angular velocity results indirectly verify the water resistance of rowing the oars from quickly kick to the upper limb force to the ribs before driving cycle is to maintain a constant resistance of this characteristic,and there are differences in resistance characteristics of drag rowing continued to increase steadily in the kinematic characteristics,angle;scope of activities in all joint professional group and the normal group had no significant difference(P > 0.05);there were significant differences in the peak angular velocity of the professional group of wrist and knee joint(P < 0.05),the peak value of angular velocity in all groups were no ordinary joint significant differences(P > 0.05);in the aspect of s EMG characteristics,in the driving process,the professional group part of the body muscle force manifested as femoral head four muscle,erector spinae,biceps brachii,deltoid muscle,The latissimus dorsi,tibialis anterior muscle,the main muscle force is the biceps brachii,deltoid muscle,latissimus dorsi muscle,and the wind resistance rowing device slightly different.Whether it is from the analysis of kinematic or EMG of major muscles professional group follow principles of muscle coordination force drives the small muscles of the lower limbs,upper limb movement and the hard way in order to not change,reasonable force.The ordinary group will not be explained here because of the obvious difference in movement.This study uses vicon 3D motion capture and surface EMG synchronization test methods of water resistance rowing oars technology movement kinematics and EMG analysis,we fully understand the rowing driving technology,provide a reference for improving the quality of training of rowing and rowing,strength has important significance to test new means and methods endurance training exploration.
