“…In light of the results for the H-M group, this indicates that in spite of the moderate-to-high ground reaction force, the stimulus for beneficial geometric adaptation seems to be diminished by the lower rate of loading. Differing from power-lifting (squat, bench press, and deadlift), weightlifting movements such as the snatch, clean, and jerk are explosive and involve more impact: peak vertical ground reaction forces are 2.5-4 times BW and estimated impact loading rates vary from about 10-50 BWs -1 [53][54][55][56]. This warrants further investigation of femoral neck strength among weightlifters.…”

“…Thus, after maximum power applied to the bar was estimated by using a simple method where the barbell weight was multiplied by Vmax (Hori et al, 2006), the WC group was found to output 35% higher maximum power per unit body weight (31.3Ϯ3.5 W/kg) than the JP group (23.1Ϯ3.0 W/kg) (pϽ0.05). Since the lifted weights in weightlifting correlated highly with the lean body mass (Okada & Funato, 1993), those findings may be attributed mainly to differences in capability to exert force and power such as muscle volume, its distribution, and muscle strength per muscular crosssectional area.During the snatch, it may be suggested that the moment of the hip joint corresponds to 2-4 times that of the knee joint and load on the hip joint is increased with increasing barbell weight (Baumann, 1988). Therefore, the extension movement of the hip joint is positioned as the most contributing joint movement during the snatch.…”

The purpose of the present study was to compare the snatch techniques of Japanese and international female weightlifters using kinematic analysis. Motion analysis of the snatch techniques conducted using videos recorded at the 2006 Women's Junior World Weightlifting Championship. The results indicated no significant differences between the snatch techniques of Japanese and international weightlifters in terms of the kinematic parameters expressed by the barbell trajectory and joint angles. However, the interval of time between the peak velocity of the hip joint and peak vertical velocity of the barbell was longer for Japanese weightlifters, while the power applied to the barbell was 35% greater for international weightlifters. These findings indicate that differences in strength and power production affected the performances of Japanese and international weightlifters. Material : Coaching and Training weightlifting squad (Gourgoulis et al., 2004). Hoover et al. made a 2-dimensional kinematic analysis on weightlifters in the U.S. National Weightlifting Championships and then suggested that the drop distance during the catch phase was long in comparison with existing reports on male weightlifters (Figure 1). Further, a study on international level weightlifters reported that male weightlifters had slower maximum velocities of the barbell being lifted than female weightlifters had (Garhammer, 1991). Thus, the previous studies on female weightlifters have shown several differences from male weightlifters. To be more competitive, it may be important to accumulate information about not only such gender differences but also various factors, e.g., Japanese domestic competitors vs. international competitors, competitive level, and age.The purpose of the present study was to clarify the technical characteristics of international and Japanese weightlifters, by analyzing kinematic movements during the snatch of female weightlifters who appeared in the Junior World Weightlifting Championships. Junior weightlifters refer to competitors 20 years old and younger, but some of them have established world or national records, outperforming senior weightlifters. By evaluating the techniques of those elite weightlifters, the present study was also intended to describe the snatch techniques of current female weightlifters and obtain information that contributes to competition improvement for Japanese competitors participating in international competitions. Methods Material and subjectsIn the 12th Women's Junior World Weightlifting Championships, held in Hangzhou, China from May 28 to June 3, 2006, the attempts of Japanese representative weightlifters and higher-ranking winners in each class were recorded by a video camera. The recordings were done as part of a research project of the Japan Weightlifting Association Sports Medicine Committee.Of the recorded attempts, the best performed attempts of the World champion (WC) and Japanese representative (JP) weightlifters were analyzed. Table 1 shows the final result and body weight of the...

“…Alongside with it searching of more effective trajectories (the most wide spread among weight-lifters) is remaining the permanent subject of their discussions. In some works trajectory (А) [16] is offered; in other -trajectory of B type [14,25]. In his turn Hiskia G. [18] came to conclusion that type C is the most wide-spread.…”

Abstract. Purpose: to determine trajectories of elite female weight-lifters' movements. Material: 137 elite sportswomen were tested. Analysis of sportswomen's bio-kinematic actions was fulfilled with the help of Weight lifting analyzer 3.0 apparatus, Germany. Results: we found correlation of barbell snatch trajectory in respect to different weight categories of sportswomen. General characteristics of barbell trajectory are equal both for men and women. We determined indicators of barbell grip deviation from vertical axis. Optimal barbell trajectory depends on relative length values of body segments and other important factors. Conclusions: it was proved that execution of 2 nd type trajectory of barbell horizontal movement is the most wide spread and effective. Such type of trajectory is the most often for high sport results off light weight categories (48-58 kg).
