Penelitian ini didasarkan karena masih rendahnya kesegaran jasmani siswa Sekolah Dasar. Hal ini disebabkan berbagai faktor diantaranya gizi dan motorik. Penelitian ini bertujuan mengetahui: (1) kontribusi status gizi terhadap kesegaran jasmani Siswa Sekolah Dasar. (2) kontribusi kemampuan motorik terhadap kesegaran jasmani Siswa Sekolah Dasar, dan (3) kontribusi status gizi dan kemampuan motorik terhadap kesegaran jasmani Siswa Sekolah Dasar. Jenis penelitian adalah rancangan penelitian observasional dengan pendekatan korelasional. Populasi penelitian ini adalah seluruh siswa Sekolah Dasar Negeri 06 Pulai Anak Air Kota Bukittingi. Teknik pemgambilan sampel dalam penelitian ini digunakan teknik purposive sampling. Instrument yang digunakan adalah Tes Kesegaran Jasmani Indonesia untuk mengukur kesegaran jasmani siswa, Status gizi dengan Indeks Massa Tubuh berdasarkan Usia (IMT/U) dan Kemampuan Motorik dengan tes kemampuan motorik. Teknik analisis data yang digunakan adalah analisis korelasi dan regresi sederahana serta ganda. Hasil penelitian ini menunjukkan bahwa: (1) Status gizi memberikan kontribusi terhadap Kesegaran Jasmani Siswa Sekolah Dasar sebesar 14.08%. (2) Kemampuan motorik memberikan kontribusi terhadap Kesegaran Jasmani Siswa Sekolah Dasar sebesar 64.32%, dan (3) Status gizi dan kemampuan motorik memberikan kontribusi secara bersama-sama terhadap Kesegaran Jasmani Siswa Sekolah Dasar sebesar 69.38% The Contribution of Nutritional Status and Motor Skill on Physical Fitness of Student in Elementary School AbstractThis research is based on the low physical fitness of elementary school students. This is due to various factors such as nutrition and motoric. The Study aimed determine: (1) the contribution between nutritional status on Physical Fitness of The Students at Elementary School, (2) the contribution between motor skill on Physical Fitness of The Students at Elementary School, and (3) the contribution of Nutritional status and Motor skill on Physical Fitness of The Students at Elementary School. The research is analysis corelational design. The population of the research was students at Public Elementary school 06 Pulai Anak Air Bukittinggi. The samples were taken with purposive sampling technique. The data were collected Indonesian Physical fitness test for measuring physical fitness, Nutritional status as well as body mass index and motor skill by using motor skill test.  The data analysis technique used is correlation analysis and simple and double regression. The results of thi study indicate that:  (1) Nutritional status contributed toward physical fitness of students at Elementary school 06 Pulai Anak Air Bukittinggi about 14.08%. (2) motor skill contributed toward physical fitness about 64.32 %, and (3) nutritional status and motor skill contributed along toward physical fitness of students at Elementary school 06 Pulai Anak Air Bukittinggi about 69.38%.

Study Purpose. This study background is that the performance of the sickle kick in Pencak Silat learning is very important to improve the athlete’s performance during the match, both when attacking and defending. The objective is to analyze the performance of the Pencak Silat sickle kick in terms of the quality of physical conditions (such as leg muscle explosive power and flexibility), and psychological elements (such as achievement motivation). Materials and methods. This study involved Pencak Silat athletes of Tangan Mas College, Padang, Indonesia. The participants who became the study sample were 30 male athletes aged 14–17 (athletes in the adolescent category). The sample selection was based on the sample criteria providing that participants had participated in regional level competitions and had attended training for at least 2 years. Data were obtained from several tests and measurements: leg muscle explosive power was measured using the Vertical Jump Test and then processed by the Lewis formula (nomogram). Flexibility was measured using the Side Split Test, achievement motivation was assessed using a questionnaire validated by experts, and a sickle kick performance was tested. The data obtained were analyzed using simple regression analysis and multiple regression analysis, followed by path analysis to calculate the coefficient value of each variable. Results. The data obtained were analyzed using structural model path analysis. Results: (1) there is an effect of leg muscle explosive power on the sickle kick performance by 21.59%; (2) there is an effect of flexibility on the sickle kick performance by 6.94%; (3) there is an effect of achievement motivation on the sickle kick performance by 9.74%; (4) there is an effect of leg muscle explosive power through achievement motivation on the sickle kick performance by 38.14%; (5) there is an effect of flexibility through achievement motivation on the sickle kick performance by 13.51%; and (6) there is a simultaneous effect of these variables by 51,41%. Conclusions. Based on the analysis of the three factors above, it was concluded that leg muscle explosive power is the dominant factor and needs to be taught and trained seriously. However, the other factors are no less important. Future studies are urgently needed to include other variables that affect the results of this study, as well as a wider number of samples to validate the results of this study.

Pencak silat is a branch of martial arts that really requires good physical condition to be able to achieve maximum performance. One of the most needed physical conditions is speed endurance. However, at this time, there is no instrument to measure speed endurance specifically for the branch of pencak silat. In pencak silat matches, the dominant technique used by fighters to carry out attacks and get value is kicks. Therefore, in the implementation of this designed test, the kick technique is used. The target to be achieved in this study is the birth of a standard instrument to measure the speed endurance of pencak silat athletes. This research is a development research that aims to develop a special speed endurance instrument for athletes in pencak silat. The stages of this study began with an analysis of the needs of the physical condition in pencak silat. After that, the next stage is carried out, namely the making of speed endurance instrument designs for pencak silat athletes. Before conducting field trials, expert validation is first carried out by involving experts in the field of pencak silat, namely pencak silat trainers, sports test and measurement experts, and sports physiology experts. Field trials were carried out by direct testing of the research sample involving 100 male and 60 female pencak silat athletes. This trial is to determine the validity and reliability of field data and to determine test norms. The data analysis technique was done by using the percentage technique. The results showed that: the instrument of speed endurance developed is suitable for use as a measure of the speed endurance of pencak silat athletes with a validity of 0.95 and a reliability of 0.97.

Masalah dalam penelitian ini karena belum diketahuinya tingkat kebugaran jasmani antara siswa kelas unggul dengan sisw kelas reguler. Tujuan penelitian ini adalah untuk melihat perbedaan tingat kebugaran jasmani siswa kelas unggul dengan kelas reguler di SMP Negeri 4 Pariaman.Jenis penelitian ini adalah penelitian komparatif. Populasi dalam penelitian ini adalah seluruh siswa SMP Negeri 4 Pariaman sebanyak 611 siswa. Teknik penarikan sampel dalam penelitian ini menggunakan teknik purposive sampling. Sampel dalam penelitian ini adalah 29 siswa dari kelas unggul dan 26 siswa dari kelas regular. Instrumen dalam peneelitian ini menggunakan Tes Kesegara Jasmani Indonesia (TKJI) untuk usia 13-15 tahun. Analisis data menggunakan uji t independent sampel dengan jumlah sampel berbeda. Hasil dalam penelitian ini menunjukkan bahwa tidak terdapat perbedaan tingkat kesegaran jasmani siswa kelas unggul dengan kelas reguler. Diman thit (1,625) < ttab (1,676). Hal ini berarti bahwa tidak terdapat perbedaan tingkat kebugaran jasmani antara siswa kelas unggul dengan kelas reguler.
