This study was aimed at investigating the effects of six-week Plyometric, Functional, and Interval training on body composition, power, and kicking speed. The study employed an experimental research design involving twenty male university students who were practitioners of Pencak Silat sports, following informed consent (average age 20.2 ± 1.32 years, height 168.9 ± 5.70 cm, body weight 63.74 ± 11.54 kg). The students were not isolated; their food intake and sleep patterns were not controlled, but they were advised not to stay up late and to avoid smoking and consuming alcoholic beverages. Participants engaged in Plyometric training once a week on Mondays, functional training once a week on Wednesdays, and interval training once a week on Fridays. Plyometric, Functional training and Interval training (PFIT) was performed for 70-80 minutes per session, for six weeks, with low intensity and moderate volume on 90 -120 contacts. There were significant improvements (p <0.05) in flexibility, force and pear power, jump height and left kick speed. Body fat, muscle mass, visceral fat and bone density also experienced significant changes (p 0.05).

Objectives: Construction workers are particularly vulnerable to musculoskeletal disorders, yet the number of studies conducted in developing nations—where these workers contribute significantly to the economy—remains insufficient. This study aims to explore the interaction between physical and psychosocial exposure and the onset of neck pain or symptoms among construction workers in a developing country. Methods: Using a cross-sectional study design, a total of 235 respondents from various construction projects participated in this study. Participants were assigned to one of 4 exposure groups: low physical and low psychosocial (which served as the reference group); low physical and high psychosocial; high physical and low psychosocial; and high physical and high psychosocial. To quantitatively assess the interaction, we calculated the relative excess risk due to interaction (RERI), attributable proportion (AP), and synergy index (SI). Results: Workers experiencing high levels of both physical and psychosocial risk factors had the highest odds ratio (OR) of neck symptoms (OR: 12.63; 95% CI: 3.39-46.99) compared with other groups. The AP (0.33; 95% CI: −0.24 to 0.90), RERI (0.40; 95% CI: −0.99 to 1.79), and SI (1.69; 95% CI: −1.77 to 5.15) revealed an interaction between physical and psychosocial factors that increases the OR of neck symptoms. Conclusions: This result suggests that physical risk factors at work become significantly more detrimental when paired with high psychosocial stress. Hence, ergonomic interventions in the construction industry aiming to reduce musculoskeletal disorders should consider both physical and psychosocial risk factors concurrently.

The goal of this instructional style is to help students become more proficient at the floor exercise roll by using a game-based approach and other forms of media. The purpose of this research is to provide evidence for the efficacy of a model for teaching the fundamentals of the floor exercise roll through the medium of a video game in junior high school. Three subject matter experts and three media specialists evaluated the research and validated the learning model using a set of established criteria. This study is occurring within the product development phase with ten stage. A questionnaire was utilised to obtain data for determining the model's accuracy. Descriptive percentages were used to assess the data. The average model validity ratings found in this research show that the material expert validator is 83.33 percent valid and the media expert validator is 89.4 percent valid. The validity score generated by the combination of the three validators is very high quality. Consequently, it is reasonable to infer that the floor exercise roll basic technique learning model based on a game is genuine and can be applied in the context of school-based sports education. Sports educators and curriculum designers can use the favourable feedback from material and media experts to inform the design of more effective learning models for students to become proficient in floor exercises and fundamental rolling technique.

Guru pendidikan jasmani menghadapi beberapa tantangan penulisan ilmiah yang dapat menghambat keefektifan mereka dalam mengkomunikasikan penelitian dan praktik pedagogi. Salah satu masalah yang signifikan adalah kurangnya pelatihan dalam penulisan akademis, yang sering kali mengakibatkan kesulitan dalam menyusun dan mengartikulasikan ide-ide mereka dengan jelas. Tujuan dari kegiatan ini adalah untuk membantu guru Pendidikan Jasmani, Olahraga dan Kesehatan (PJOK) dalam meningkatkan pengetahuan dan pemahaman penulisan karya ilmiah dengan bantuan kecerdasan buatan (Artificial Intelligence). Kegiatan ini diikuti oleh 25 Guru PJOK yang telah tergabung dalam Ikatan Guru Olahraga Nasional (IGORNAS) dari berbagai provinsi di Indonesia. Kegiatan ini terdiri dari 3 tahap, yaitu pra-kegiatan, kegiatan, dan pasca kegiatan. Luaran dari kegiatan ini selain peningkatan pengetahuan penulisan artikel ilmiah dengan bantuan kecerdasan buatan juga berupa artikel yang disubmit di Jurnal Olahraga Pendidikan Indonesia (JOPI). Untuk mengetahui ada tidaknya peningkatan maka dilakukan tes awal dan tes akhir. Instrumen yang digunakan untuk mengetahui pengetahuan awal dan akhir adalah kuesioner yang dimuat dalam Google Form. Para peserta mengakses dan mengisi kuesioner dalam satu ruangan secara bersamaan. Ada tidaknya peningkatan diketahui dari ada tidaknya peningkatan nilai rata-rata tes awal dan tes akhir. Hasil kegiatan pelatihan dan pendampingan menunjukkan bahwa pengalaman submit ke jurnal mengalami peningkatan sebesar 56% karena semua penulis wajib mengirimkan naskah yang telah disusun selama pelatihan ke JOPI, sedangkan persentase tertinggi kedua terjadi pada peningkatan pengetahuan aplikasi cek plagiasi (24%). Sementara itu, pemahaman tentang model penulisan daftar pustaka tidak terjadi peningkatan sama sekali. Secara keseluruhan, meskipun AI menjanjikan untuk mendukung guru dalam penulisan ilmiah, sangat penting untuk menyeimbangkan penggunaannya dengan evaluasi kritis dan standar etika.
