Relationship between kinetic variables of weightlifters to lift the barbell to its maximum height in the snatch lift and kinetic variables in the stage of dropping the barbell

Abstract

The objective of the present research was to study the relationship between kinetic variables of weightlifters to lift the barbell to its maximum height in the snatch lift and kinetic variables in the stage of dropping the barbell. The research sample consisted of 6 Iraqi national team weightlifters. The instruments used in this study were weightlifting tools, 1-meter-long drawing scale, Rustameter device to measure the height, two Canon video cameras, a scale to measure the weight of weightlifters, an attempt scoreboard, and a portable personal computer. Regarding the attempts for the snatch lift, three attempts were given to each weightlifter according to international weightlifting regulations, and the best successful attempt was analysed. The statistical analyses were carried out with the Statistical Package for the Social Sciences (SPSS), version 23. There were three significant correlations between the work done dropping the barbell and the momentum, energy and power lifting the barbell (p<0.05). In conclusion, the increase of the momentum, kinetic energy, work done, and power has a positive role in the process of lifting the barbell to its maximum height in the snatch lift and dropping the barbell.
