TRIAL DESCRIPTION
Public title Boosting Judo Skills: How Self-Controlled Learning Enhances Uchi-mata in Secondary School Students
Official scientific title Empowering Skill Acquisition: Unleashing the Potential of Self-Controlled Strategies in Technology-Mediated Motor Learning for Enhanced Uchi-mata Technique in Secondary School Judo Practitioners
Brief summary describing the background and objectives of the trial Motor learning in sports pedagogy is increasingly integrating technology to enhance skill acquisition. This study explores the effectiveness of technology-mediated instructional strategies in improving the Uchi-mata technique among secondary school judo practitioners. The research is grounded in the need to identify optimal teaching methods that leverage video demonstrations and feedback to boost learners' technical proficiency. By examining self-controlled and imposed schedules, the study aims to provide insights into how these different approaches impact motor skill development in a judo context.

STUDY DESIGN
Intervention assignment Allocation to intervention If randomised, describe how the allocation sequence was generated Describe how the allocation sequence/code was concealed from the person allocating the participants to the intervention arms Masking If masking / blinding was used
Parallel: different groups receive different interventions at same time during study Randomised Simple randomization using by using procedures such as coin-tossing or dice-rolling Sealed opaque envelopes Open-label(Masking Not Used)
INTERVENTIONS
Intervention type Intervention name Dose Duration Intervention description Group size Nature of control
Experimental Group SC twice a week for 2 weeks Each SC intervention session lasted 45 minutes For the SC group, each participant was informed that they could access either the video feedback of their Uchi-mata or a video demonstration. Moreover, he has the right to move on to the next test without seeing any techno-pedagogical tool. The group (SC) sessions are scheduled before the group (YK) sessions. The number and type of video watched was recorded in each session learning for all participants. 12
Control Group YK twice a week for 2 weeks Each YK intervention session lasted 45 minutes For the YK group, participants had no control over the schedule of their techno-pedagogical tool. Students were told they would receive either a video demonstration or video feedback after some trials, but not others. Their timing of viewing the techno-pedagogical tools depended solely on when their height- and weight-matched counterpart in the SC group chose to view the videos. For example, if a student in group SC chose to watch a video demonstration after trials 2 and 5, and video feedback after trial 8, their counterpart in the other group must undergo a video demonstration immediately after trials 2 and 5, followed by a video feedback after trial 8 in an imposed manner. 12 Active-Treatment of Control Group

OUTCOMES
Type of outcome Outcome Timepoint(s) at which outcome measured
Primary Outcome Uchi-mata technical performance A mixed-design [2 groups (SC; YK) × 3 Time (T0; T1; T2)] ANOVA (Figure 1) with repeated measure on the second factor showed (i) a significant Time effect for Technical performance of Uchi-mata exercise ( F(2, 44) = 27.14, p < 0.001, ղp2 = .55), (ii) a no significant group effect ( F(1, 22) = 5.36, p = 0.07, ղp2 = .14), and (iii) a significant effect of a group-by-Time interaction ( F(2, 44) = 5.42, p = .008, ղp2 = .20). February 6, 2024: pre-test February 20, 2024: post-test February 27, 2024: retention test
Secondary Outcome For SC group, compared with pre-test (T0), the post-hoc test showed higher scores at (i) posttest (T1) for the technical performance (p<0.001, Δ 99 ± 54%, Hedges’g = 2.02), and at (ii) retention test (T2) (p<0.001, Δ 113 ± 87%, Hedges’g = 2.15). For YK group, a significant difference was detected only between posttest versus pretest (p<0.05, Δ 44 ± 35%, Hedges’g = 1.06) with increased scores at posttest. In addition, the post hoc test revealed that the SC group presented significantly higher retention test scores compared to (YK) group for the technical performance (p < 0.05).
