Our aim in this study was to examine, via technical performance analysis and speed of execution, whether information processing and technical knowledge help explain learning benefits of self-controlled video feedback in children’s weightlifting performance. We randomized 24 children (aged 10 to 12 years) into self-controlled (SC) and yoked (YK) feedback groups. Learners underwent test sessions one week before (pre-test) and one day after (post-test) six weightlifting training sessions. During each test session, we recorded kinematic parameters of snatch performance using Kinovea version 0.8.15 software. After the learning sessions, the SC group improved on most kinematic parameters (e.g., the horizontal displacement of the bar between the first and the second pulls [ MDXV = 25.42%, SD = 18.96, p = 0.003) and the maximum height reached by the bar ( MHMV = 5.51%, SD = 7.71, p < 0.05)], while the YK group improved only on the DxV ( MDXV = 19.08%, SD = 24.68, p < 0.05). In addition, the SC group showed a more advanced phase of cognitive processing compared to the YK group, and the SC group showed a superior improvement in their technical knowledge level ( p < 0.001) compared to the YK group ( p < 0.05). Thus, key elements to correcting motor errors in children’s weightlifting through self-controlled feedback were improvements in information processing and technical knowledge.

The purpose of the present study was to investigate which of two strategies, Video Feedback with Pedagogical Activity (VF-PA) or Video Feedback (VF), would be more beneficial for the remote error correction of the snatch weightlifting technique during the confinement period. Thirty-five school aged children with at least three months of weightlifting experience were randomized to one of three training conditions: VF-PA, VF or the Control group (CONT). Subjects underwent test sessions one week before (T0) and one day after (T1) a six-session training period and a retention test session a week later (T2). During each test session, the Kinovea version 0.8.15 software measured the kinematic parameters of the snatch performance. Following distance learning sessions (T1), the VF-PA improved various kinematic parameters (i.e., barbell horizontal displacements, maximum height, looping and symmetry) compared with T0 (p < 0.5; Cohen’s d = 0.58–1.1). Most of these improvements were maintained during the retention test (T2) (p < 0.01, Cohen’s d = 1.2–1.3) when compared withT0. However, the VF group improved only twoparameters (i.e., barbell symmetry and horizontal displacement) at T1 (p < 0.05; Cohen’s d = 0.9), which were not maintained at T2. Better horizontal displacement and looping values were registered during the retention test in the VF-PA group compared with the CONT group (p < 0.05, Cohen’s d = 1.49–1.52). The present findings suggest combining video feedback with pedagogical activity during the pandemic induced online coaching or physical education to improve movement learning in school aged children.

This study aimed at assessing the impact of video modeling examples (VMEs) on secondary school students’ self-regulated learning experiences in gymnastics in original physical education (PE) settings. A total of 56 students (28 males and 28 females), aged 16–17, took part in a seven-week gymnastics learning unit for the purpose of acquiring new motor skills and knowledge using VMEs, in the absence of teacher and peer assistance. Repeated measurements were collected through gymnastics floor routines and a custom-designed written test. Semi-structured interviews were administered to explore students’ self-regulated learning strategies. The analysis of quantitative data revealed significant improvements in males’ skill performance (pre: 4.54  ±  2.42, post: 10.97  ±  3.25 points; p <  0.001) and knowledge (pre: 6.43  ±  2.26, post: 13.19  ±  3.09 points; p < 0.001), as well as females’ skill performance (pre: 2.64  ±  2.09, post: 8.96  ±  4.12 points; p < 0.001) and knowledge (pre: 6.14  ±  2.48, post: 10.97  ±  3.25 points; p < 0.001) after taking part in the practical intervention. Sex-based differences, in favor of the males, were only observed in knowledge outcomes (males: Δ (Δ%) = 6.76 (105.1%), females: Δ (Δ%) = 4.25 (69.2%); p < 0.05). Qualitative data analysis yielded three major learning strategies: repeated viewing and interpretation of VMEs, self-talk and mental rehearsal. In conclusion, VMEs were able to empower the participating students to acquire motor skills and knowledge in PE classes through activating different metacognitive learning strategies, and even without resorting to teacher/peer assistance. Data from this study could prompt PE teachers to incorporate VME-mediated self-regulated learning methods into their teaching practices for better classroom management and for improving their students’ metacognition.
