Abstract des Autors
The aim of this study was to analyze the snatch lift techniques used by six international weightlifters. The variations in vertical force Fz(t) were examined using loads of 70%, 80% and 90% of their maximum performance. With a force platform and a 2-D video analysis system the different critical points on these pull-snatch curves Fz(t) can be identified: two maximums (Tz1, Fz1) and (Tz3, Fz3), separated by a minimum (Tz2, Fz2). These technical phases were translated kinetically and dynamically from the technical phase transitions. The high correlations (r>0.80, P<0.05) of the critical points (Tz1, Fz1; Tz2, Fz2; Tz3, Fz3), and its effect on the kinetic variables of the bar should be noted. The reduction in the force ratio Fz1/Fz2, and the increase in Fz3/Fz1 give an indication of the technical potential of the weightlifter. Verf.-Referat
