Pengaruh Perekaman Diri Berbasis Video dengan dan Tanpa Pengawasan Pelatih terhadap Keterampilan Dasar Tenis Pemula: Mengontrol Efikasi Diri Dasar

Abstrak

Study purpose. This study analyzed and compared the effects of three training models on beginner tennis players’ fundamental skills and self-efficacy.

Materials and methods. An experimental pretest–posttest control group design involved 24 first-semester students (12 male, 12 female) from the Siliwangi University Tennis Club with no formal tennis training. Participants were randomly assigned to: (1) video-based self-recording monitored by a coach via online supervision, (2) video-based self-recording without monitoring, and (3) unsupervised free-practice control. The intervention lasted 12 weeks (3 sessions/week; 36 sessions). This training session lasted 120 minutes, including a 15-minute warm-up, 90 minutes of main training, and a 15-minute cool-down. The intensity of the training was controlled at a low to moderate level (60%–75% of HRmax). Forehand accuracy (FA) and backhand accuracy (BA) were measured using the Dyer Tennis Test, service accuracy (SA) using the Hewitt Tennis Achievement Test, and self-efficacy (SE) using the Endurance Sport Self-Efficacy Scale (ESSES). Paired -tests assessed within-group changes, and MANCOVA tested posttest skill differences while controlling for pretest SE.

Results. Only Group 3 showed no significant improvement in BA (p = 0.109); Groups 1 and 2 significantly improved FA, BA, SA, and SE (p < 0.005). Group had a significant multivariate effect on posttest tennis skills after controlling for pretest SE (p < 0.001; ). Pretest SE significantly influenced FA, BA, and SA (p = 0.021; ), predicting posttest FA (p = 0.027) and SA (p = 0.036), but not BA (p = 0.221).

Conclusions. Video-based self-recording improves beginner tennis skills and self-efficacy beyond unsupervised free practice. Baseline self-efficacy should be considered in training design because it relates to post-intervention performance, particularly forehand and service accuracy. Future research should involve larger, diverse samples, include retention tests, and explore equipment modifications reported to enhance technical control and self-efficacy in beginners.
