Abstract

This study investigates the effect of racket grip strength and motion anticipation on the effectiveness of spin serves among junior tennis athletes in Makassar. Using a quantitative correlational design, 20 athletes aged 14–18 years participated. Grip strength was measured with a handgrip dynamometer, motion anticipation with a visual reaction test, and spin serve effectiveness through video analysis of accuracy, direction, and bounce. Multiple regression analysis (α = 0.05) showed that both variables significantly affected spin serve effectiveness (R² = 0.551; p < 0.05). Grip strength had a greater contribution (β = 0.46; p = 0.008) than motion anticipation (β = 0.39; p = 0.018). The findings highlight the importance of integrating physical and cognitive training to enhance spin serve performance in junior tennis athletes. Strength and anticipation training should be combined to optimize serve outcomes

Abstract

This study investigated the effect of aerobic dance frequency and duration on cardiorespiratory fitness in adolescent girls in Makassar. Using a quasi-experimental pre-test and post-test control design, 40 girls aged 17–22 were divided into experimental and control groups (n=20 each). The experimental group performed aerobic dance three times per week for 45–60 minutes over eight weeks, while the control group continued routine activities. Cardiorespiratory fitness was measured using the 12-minute Cooper Test. Data analysis included normality, homogeneity, paired t-tests, and independent t-tests. Results indicated a significant VO₂max improvement in the experimental group (Δ mean = +4.70; p < 0.001) compared to no significant change in the control group (Δ mean = -0.35; p > 0.05). The post-test difference between groups was also significant (t = -3.756; p < 0.001). Regular aerobic dance effectively enhances cardiorespiratory fitness in adolescent girls.

Abstract

Program Gerakan Sehat Bersama merupakan kegiatan pengabdian masyarakat yang bertujuan untuk meningkatkan kebugaran jasmani dan kesadaran hidup sehat pada remajajen. Kegiatan ini dilaksanakan dengan pendekatan partisipatif, edukatif, dan berkelanjutan melalui beberapa tahapan, yaitu sosialisasi, pelatihan olahraga, pemanfaatan teknologi, pendampingan, serta evaluasi. Pelatihan olahraga dasar seperti senam, lari, dan peregangan dilakukan secara rutin dengan melibatkan tenaga pelatih dan kader lokal. Hasil kegiatan menunjukkan peningkatan pengetahuan peserta mengenai pentingnya olahraga dan gizi seimbang, serta peningkatan kemampuan fisik seperti daya tahan, fleksibilitas, dan kekuatan otot. Selain itu, terbentuk enam kader olahraga yang berperan aktif dalam menggerakkan masyarakat untuk terus berolahraga. Dukungan sekolah dan pemerintah desa turut memperkuat keberlanjutan program. Secara keseluruhan, program ini berhasil meningkatkan kesadaran, partisipasi, dan perilaku hidup sehat remaja serta membentuk budaya olahraga berkelanjutan di masyarakat.
