- Abstract
This study aimed at comparing the efficiency of two viewing control strategies, total control versus partial control, in correcting the snatch technique in school-aged boys (10–12 years old). Thirty-nine participants, with 2 months of weightlifting training experience, were divided into three groups: total control, partial control, or a control group. The Kinovea version 0.8.15 software was used to measure the kinematic parameters of the snatch technique before (T0) and after six learning sessions (T1). Following the learning sessions, total control group showed greater improvements for all kinematic parameters compared with the partial control and control group (e.g., the horizontal displacement (i) in the first pull (Δ Dx2: 18.17 ± 26.75%, p < 0.01, d = 0.83), (ii) between the first and the second pulls (Δ DxV: 25.97 ± 18.02%, p < 0.001, d = 1.52) and from the most forward position to the catch position (Δ DxL: 19.98 ± 21.60%, p < 0.01, d = 1.36), while the partial group improved only on the Dx2 (Δ Dx2 = 21.53 ± 20.40%, p < 0.01, d = 0.86). The present results indicate that the intensive use of the interactive features (e.g. pause, play, forward, and backward) and the asked questions during the first learning phase were essential for the improvement of the snatch technique. These findings have potential practical implications for coaching and physical education teaching.
