High achievment in sports requires behavior with certain qualities. Likewise, with successful athletes, they have superior qualities not only in terms of physical but also mentality. This study aims at examining psychological characteristic because it’s one of the important factors possessed by athletes, and can influence them in. The sample used in this study are 198 East Java athletes who participates in the training center from 21 sports. The instrument used for psychological characteristics in this study is the SKPA (Scale of Psychological Characteristics for Athletes) with a factor loading value > 0.5, so that each item is valid in measuring it’s dimensions, and it’s known that the conbrach’s alpha value for each dimension is 0.7. Of the eight psychological characteristics, the highest mean value for hard work is 16.31. And the lowest mean values for opennes is 12.02. Eight psychological characteristics indicate a good category, which means that the psycology of the East Java regional training center athletes are in good condition.

Tujuan dari penelitian ini untuk mengetahui gambaran Indeks Massa Tubuh, Pola Makan dan Aktivitas Fisik. Serta korelasi antara Indeks Massa Tubuh dan Pola makan dengan aktiviatis fisik peserta didik SMAN 1 Indralaya Selatan. Jenis penelitian ini adlah Deskripsi Kuantitatif dengan menggunakan metode survei menggunakan perhitunagan IMT, Internasional physical activity quetionnaire (IPAQ), dan Food Frequency. Populasi pada penelitian ini yaitu peserta didik SMA Negeri 1 Indralaya Selatan. Sampel yang dipakai yaitu siapa saja yang ditemui oleh peneliti bisa dijadikan sebagai sampel berdasarkan subjek penelitian (Accidental Sampling). Data yang dianalisis menggunakan korelasi dan uji Chi-Square. Untuk hasil Indeks Massa Tubuh (IMT) menunjukan bahwa 53 (48%) orang peserta didik dengan ketegori underweight. Untuk hasil pola makan menunjukan bahwa 53(48%) orang peserta didik dengan kategori kurang. Sedangkan untuk hasil aktivitas fisik 57(52%) orang peserta didik dalam kategori sedang. Kesimpulan pada penelitian ini adalah tidak ada hubungan antara indeks masa tubuh terhadap aktivitas fisik dengan nilai P valui 0,311>0,05. Tidak ada hubungan antara pola makan terhadap aktivitas fisik dengan nilai p valui 0,569>0,05. Dan tidak adanya korelasi antara indeks massa tubuh dan pola makan terhadap aktivitas fisik peserta didik SMA Negeri 1 Indralaya Selatan dengan nilai sig. f change 0,702> 0,05 dan nila rhitung sebesar 0,081 termasuk dalam korelasi rendah.

Tujuan penelitian ini adalah untuk menentukan instrumen pengukuran kebugaran jasmani pada anak usia 10-12 tahun. Usia tersebut rata-rata anak yang sekolah pada tingkat dasar kelas 4-6. Jenis penelitian yaitu metode survei dengan teknik analisis data deskriptif persentase. Purposive accidental sampling digunakan dalam penelitian ini. Responden yang terlibat pada penelitian ini adalah 128 responden yang terdiri dari 19 responden adalah dosen dalam bidang keolahragaan dan 109 responden adalah guru PJOK tingkat SD. Hasil penelitian bahwa alat ukur untuk kebugaran jasmani yang berkaitan dengan Kesehatan yang dapat diterapkan pada sebagian besar sekolah dasar dengan memperhatikan kondisi sarana dan prasarana adalah weight, height, and body mass index (komposisi tubuh), 20-meter multi-stage shuttle run (daya tahan kardiorespirasi), sit-and-reach test (kelentukan), push-ups (daya tahan otot), dan maximal handgrip strength test (kekuatan otot).

Learning, which focuses on higher-level thinking skills, can be applied in the physical education curriculum through games and sports, movement education, and outdoor education. This study aims to produce a learning model that effectively improves the physical fitness and critical thinking skills of students. Purposive sampling was used in selecting research sample members in which 308 (M: 153 and F: 155) fifth-grade students participated in this study. Two groups were selected as research subjects divided into small groups for the first stage test (N: 123; M: 56; F: 67; Average age: 10.82) and large groups for the second stage test (N: 185; M: 97; F: 88; Average age: 10.70). Five indicators of critical thinking skills were measured through a critical thinking skills instrument. Meanwhile, the indicators of physical fitness tests include BMI, Sit and Reach, Sit-Up, Trunk Lift, and PACER 20-M. The results showed that physical education, oriented towards peer observation carried out during the learning process, self-assessment carried out by students, and packed in the circuit learning method is proven to improve critical thinking skills and physical fitness.

This study aims to analyze the effects of augmented reality (AR) training in improving physical fitness and technical performance. An 11-week randomized controlled design was adopted in this study. This research involved sixty female athletes in Pencak Silat and Karate from Sriwijaya University (Indonesia). Participants were allocated into the experimental group, namely AR (Pencak silat: n=15, Karate: n=15) and control group (Pencak silat: n=15, Karate: n=15). Handgrip dynamometer, leg dynamometer test, medicine ball, standing long jump test, hexagon agility test, sit and reach test and multi stage test are used to measure physical fitness levels while the target punching test and target kick test are used to measure technical performance. The results of Student's t showed that there was a change in the mean value of AR (all, p < 0.05) and control only in MBT (p < 0.05) from baseline to final-test, ANOVA analysis we observed that there was an effect of Time on physical fitness (all, p < .001), there was a Group effect related to HDT (p < .001), MBT (p = 0.043), SART (p < .001), and MST (p < .001) and there was a Time * Group interaction related to HDT (p < .001), LDT ( p = 0.029), SLJT (p < .001), HAT ( p < .001), SART (p < .001), and MST (p < .001), there was an effect of Time on technical performance (all, p < .001), Group effect related to TPT (p = 0.004), and Time * Group interaction related to TPT (p = 0.001) and TKT (p < .001). Thus, we conclude that using AR for 11 weeks is an effective training method for improving the quality of physical fitness and technical performance of young athletes in combat sports.
