| Summary: | The majority of the research to date on weightlifting has focused on two senior female 2004 and 2008 Olympic gold medal weightlifters. The performances of 6 women weightlifters were Thai Youth National Team and performing in the final selected for the representative of Thailand national weightlifter in the Youth Olympic Games 2010 competition in Singapore. The kinematics data of the barbell were recorded and analyzed using Peak Motion Analysis. 2-D Motion Analysis system from the snatch lift including barbell resultant trajectory, vertical and horizontal displacement, peak height, velocity, and acceleration. The performance of the athletes competing in 69-kg class and 48-kg class and the average age 15.8 years old the snatch attempts only once performance with the maximum lifting. The results showed that the average of barbell peak height were 1.29±0.1m, vertical barbell displacement 0.144±0.03m, horizontal barbell displacement 0.180±0.28 m, maximum vertical barbell velocity 2.84±0.26 m/s at 31±4 time % snatch, and maximum vertical barbell acceleration 23.59±4.34m/s2 at 29±6 time % snatch, respectively. The results of this study suggest that the appearance of the second pull in maximum vertical velocity and acceleration with time % snatch of weightlifters could be used as a criterion of lifting skill and a measure of performance. |
