The research aims to find out if there is a influence on the traditional sport activity of 40 meters in class V students of elementary school 029 Loa Janan. This type of research is field experimentation by involving two free variables i.e. traditional sports police vs. theft and traditional sports clasd and variable bound i.e. running 40 meters population in this study are all students/I SD State 029 Loa Janan which amounted to 13 people data analysis techniques used are descriptive statistics and statistic inferential by using T-test test techniques. Based on the analysis of data obtained results: (1) T-count value > T-table value, 9,354 > 1,943 or there is a influence of traditional sport activity of police vs. theft to the running speed of 40 meters to the running speed of 40 meters in grade V students of SD State 029 Loa Janan. (2) T-count value > T-table value, 7,348 > 2,015 or there is an influence of traditional sporting activity in the event of a running speed of 40 meters in class V student elementary School 029 Loa Janan.

Senam aerobik merupakan salah satu bentuk olahraga yang banyak diminati oleh sebagian masyarakat dari golongan bawah sampai golongan atas, khususnya wanita. Baik pria maupun wanita bersama-sama melakukan senam aerobik demi memperoleh kebugaran dan kegembiraan. Pengertian senam aerobik adalah serangkaian gerak yang dipilih secara sengaja dengan cara mengikuti irama musik yang juga dipilih sehingga melahirkan ketentuan ritmis, kontinuitas dan durasi tertentu. Oleh karena itu olahraga senam aerobik juga harus dilatih kondisi fisiknya untuk meningkatkan daya tahan otot jantung, daya tahan otot lengan, daya tahan otot perut, dan kelentukan. Hal ini merupakan beberapa komponen kondisi fisik yang harus dimiliki dengan baik oleh setiap member senam aerobik.  Tujuan dari penelitian ini adalah untuk mengetahui tingkat kondisi fisik anggota unik kegiatan mahasiswa  senam aerobik putri Unusa. Subjek penelitian ini adalah anggota unik kegiatan mahasiswa  senam aerobik putri Unusa  yang diambil 20 orang. Metode dalam analisa ini menggunakan metode statistik kuantitatif deskriptif, sedangkan teknik pengumpulan data dilakukan dengan melakukan tes yang meliputi: daya tahan otot jantung, daya tahan otot lengan, daya tahan otot perut, dan kelentukan. Kesimpulan hasil penelitian. (1) Mayoritas daya tahan otot jantung anggota unik kegiatan mahasiswa senam aerobik putri Unusa adalah sangat tidak bugar. Tingkat prosentasi daya tahan otot jantung adalah 0% sangat bugar, 0% bugar, 0% di atas rata-rata 0% rata-rata, 0% di bawah rata-rata, 10% tidak bugar, dan 90% sangat tidak bugar. (2) Mayoritas daya tahan otot lengan anggota Unik kegiatan mahasiswa  senam aerobik putri Unusa adalah kurang. Tingkat prosentasi adalah 0% baik sekali, 10% baik, 10% sedang, 70% kurang. Dan 10% kurang sekali. (3) Mayoritas daya tahan otot perut anggota unik kegiatan mahasiswa senam aerobik putri Unusa adalah kurang. Tingkat prosentase adalah 0% baik sekali, 0% baik, 10% cukup, dan 90% kurang. (4) Mayoritas kelentukan anggota unik kegiatan mahasiswa senam aerobik putri Unusa adalah kurang sekali tingkat prosentase adalah 0% baik sekali, 0% baik, 10% cukup, 20% kurang, dan 70% kurang sekali.

The purpose of this study was to determine the interaction between the training method and the explosive power of the leg muscles on the learning outcomes of the 100 meter run. This research was conducted at the Teaching and Education Faculty of Mulawarman University with an experimental method, with a 2 x 2 factorial design. The sample in this study was 120 students, divided into 4 groups, each group consisting of 30 students. Analysis of the data used is a two-way Analysis of Variance (ANOVA). The results of the study stated that: (1) The acceleration sprint training method and the sprint training method did not have different effects on improving learning outcomes in running 100 meters, Fo = 5.452 > Ft5% db (1;116) = 3.84, (2) Without paying attention to the use of the two forms of training methods (acceleration sprint training method and the sprint training method), the explosive power of the strong leg muscles has a different effect when compared to the explosive power of the weak leg muscles on the learning outcomes of running 100 meters, Fo = 0.237 ? Ft5% db (1;116) = 3.84, (3). There is an interaction between the training method and the explosive power of the leg muscles on the learning outcomes of the 100 meter run, Fo = 13.044 > Ft5% db (1;116) = 3.84.

Based on the background above, the researchers wanted to find out how the motor skills of elementary school children after online learning during the COVID-19 pandemic. This is useful in knowing the motor skills of students after the online learning of the COVID-19 pandemic, so that the teacher can then adjust the PJOK teaching given and the appropriate method so that the motor skills of students, if previously lacking, can improve better. In addition, if students know the category of their motor skills, they can then be improved so that development and growth can be monitored properly and correctly.
