Introduction: Because of the fact that detailed data on the physiological characteristics of Pencak Silat are still limited. The primary purpose of this study to assess the physiological responses of Pencak Silat athletes and a secondary aim is to compare the physiological responses of Pencak Silat athletes with physiological responses of Taekwondo athletes. Material and Methods: This study has included 17 male junior martial art athletes (aged 15–16 years). This study requires all participants to completed one familiarization session and two experimental sessions. During the first session (laboratory condition), anthropometry was measured in the laboratory, and during the second session (on-court condition), the participants completed tests for anaerobic capacity (sprint test 60-m, vertical jump, push-ups, and sit-ups) and VO2max test. Results: The statistical analysis revealed no significant differences in anthropometry, vertical-jump, sit-ups, push-ups, and 60-m sprint results among TKD and PKS groups. Furthermore, the TKD group had significantly higher VO2max (p=0.015), when compared with the PKS group. Conclusion: The present investigation describes similar physiological characterizes, such as weight, height, BMI, BMR, body fat and also performances of vertical jump, sit-ups, push-ups, and 60-m sprint tests among Taekwondo and Pencak Silat athletes. However, in comparison with junior Pencak Silat athletes, the junior Taekwondo athletes have better VO2max.

Aktivitas fisik dan gaya hidup sangat penting untuk kesehatan, karena kebiasaan aktivitas fisik dan gaya hidup yang sehat akan berdampak kepada perkembangan fisik anak. Aktivitas fisik dan gaya hidup anak harus diperhatikan sejak dini. Tujuan penelitian ini adalah untuk melihat tingkat aktivitas fisik siswa. Metode penelitian menggunakan metode deskriptif kualitatif, dengan melibatkan 48 siswa Sekolah Dasar kelas 5, dengan rata-rata usia 11 tahun. Tingkat aktivitas fisik didapatkan dari hasil pengolahan kuesioner IPAQ (International Physical Activity Quessionare). Sebelum melakukan pengisian kuesioner, para responden mendapatkan penjelasan mengenai pertanyaan yang ada dalam kuesioner tersebut. Hasil penelitian ini menunjukan rata-rata responden berusia 11.2 (± 1.01) tahun, tinggi badan 155.1cm (± 3.1), berat badan 38.5kg (± 6.5). Tingkat aktivitas fisik dirata-ratakan masuk dalam kategori rendah, atau dengan angka 502.2(±24.3) METs.

Purpose. Foam rolling (Fr) is a known recovery method based on self-myofascial release. Detailed data on Fr to reduce muscle fatigue and enhance performance in futsal athletes are still limited. The study aimed to assess whether Fr was a suitable recovery method for futsal athletes to enhance performance and reduce their lactic acid concentration. Methods. A total of 30 male futsal athletes participated in this study. They were randomly divided into 2 groups: 15 subjects assigned to the experimental (Fr) group practised foam roller exercises, while 15 individuals assigned to the control group were given slow jogging recovery. Both groups completed pre-and post-recovery tests for anaerobic capacity and agility. Blood lactate was measured before the experiment, immediately after the tests, and immediately after recovery. A 2 × 2 repeated measures analysis of variance (ANOVA) was used to calculate each parameter results. Results. In the post-recovery lactate concentration, the independent t-test revealed a significant decrease between pre-and post-test values in the Fr group (p = 0.033). conversely, an increase in lactate between pre-and post-test measurements occurred in the control group (p = 0.058). Furthermore, ANOVA revealed significant time × group interactions (p = 0.002) and a significant main effect for group (p = 0.001). Conclusions. Fr after exercise-induced muscle fatigue had an effect on the recovery of elite futsal players by increasing the rate of blood lactate clearance. There was no increase in performance in 20-m sprint or agility (t-test).

Kebiasaan untuk beraktivitas fisik sejak dini berperan penting dalam membangun gaya hidup yang sehat serta derajat kebugaran di kemudian hari. Riset ini berupaya untuk mengetahui sebarapa besar tingkat aktivitas fisik siswa SMA di Jawa Barat, yang pada akhirnya dijadikan acuan dan tolak ukur dalam pembuatan kebijakan dilingkungan olahraga. Metode yang digunakan dalam penelitian ini merupana random sampling, tersebar di 5 kota/kab yang ada di Jawa Barat. Metode penelitian ini menggunakan metode penelitian deskriptif kuantitatif. Data tingkat aktivitas fisik didapatkan dari kuesnioner IPAQ (International Physical Activity Questionnaire). Hasil dari kuesioner tersebut rata-rata tingkat aktivitas fisik dalam kategori tinggi, dengan nilai metabolic equivalent (METs) 3520.2 (±2774.3). Paling tinggi tingkat aktivitas fisik di Kota Tasikmalaya, sedangkan paling rendah ada di Kabupaten Kuningan. Namun dari kelima kota tersebut tidak ada perbedaan yang signifikan. Kesimpulannya kategori tingkat aktivitas fisik siswa SMA Jawa Barat tinggi, namun ada beberapa catatan karena mereka memiliki durasi duduk yang cukup tinggi serta kebiasaan bermain permainan daring yang terlalu sering.
