Metrological assessment of training and competitive exercises for weightlifters

Aim. The paper aims to reveal features of movement kinematics in training and competitive exercises for weightlifters. Material and methods. The research involved female weightlifters aged 17-20 years (First Adult Category Athletes and Masters of Sport of the Russian Federation). Metrological assessment was applied to 11 push training routines. In total, 374 measurements were performed. Anthropometric methods were used to measure acromial height, leg length, hip length, tibia length, arm length, shoulder length, and forearm length. The Physics Toolbox Accelerometer sensor app was used to carry out kinematic measurements. Results. The majority of positive correlations of barbell acceleration time was connected with the acromial height, being the height an athlete should reach with his barbell, which can be associated with greater or lesser effort. It was established that athletes with higher skills demonstrated better exercise duration. This may be an effect of height parameters as a result of a high correlation between acromial height and sports excellence (r = 0.8, р function show_eabstract() { $('#eabstract1').hide(); $('#eabstract2').show(); $('#eabstract_expand').hide(); }
