Learning effects of triple continuous jumping snatch intervention on the second pull of the snatch for novice lifters

This study aimed to compare the effects of triple continuous jumping snatch (TCJS) intervention training on the technique and performance of novice lifters. Males (n = 22; age = 19.7 +/- 0.9 years; height = 173.7 +/- 6.1 cm; body mass = 76.3 +/- 11.8 kg) who had no training experience in weightlifting were randomly assigned to a control (CG; n = 11) or an experimental (EG; n = 11) group, and trained three times a week for 8 weeks. The CG was trained in the snatch, and EG intervened with TCJS. In the initial state, t-tests and Hedges' effect sizes revealed significant and very large-to-nearly perfect differences (p < 0.001, g = 6.39) for barbell velocity while the barbell made contact with the body and the maximal barbell acceleration after contact (p < 0.001, g = 3.79) between CG and EG. Moreover, differences in the angle between the barbell and the shoulder prior to the turnover phase exhibited significant and moderate decreases in weeks 2, 6, and 8 (all p < 0.05, g = 0.63-0.98) by performing the snatch with the TCJS intervention. The TCJS not only impacts barbell velocity and acceleration immediately, but also reduces horizontal movement between the barbell and body. The results of this study demonstrated that the TCJS constitutes a superior training method for novice lifters to enhance the stability of techniques when compared with snatch.
