The objectives of this study are The effect of volleyball on the physical fitness level of UPN "Veteran" Yogyakarta Industrial Engineering study program students, the influence of soccer on the physical fitness level of students of the Industrial Engineering study program UPN "Veteran" Yogyakarta, the difference in the influence of volleyball and soccer on the level of physical fitness of students of the industrial engineering study program UPN "Veteran" Yogyakarta. This research uses an experimental method. The subjects of this study consisted of students of the UPN "Veteran" Yogyakarta industrial engineering study program who took Sports II courses in volleyball and football. The sampling technique is a targeted random sample, with a sample of 25 participants in each group. This research data analysis method uses a t-test. The normality test (Kolmogurov-Smirnov, α = 0.05) and the variance homogeneity test (Levene test, α = 0.05) were used to test the data analysis requirements. The results of the research are as follows: Football has an influence on improving the physical fitness of industrial engineering students at UPN "Veteran" Yogyakarta, with an average pre-test result of 34,748 post-test results of 37,864 students, with an average increase in the number of students of 3,121 cases showing that physical fitness increases through football. 2) Volleyball has an effect on the physical fitness of industrial engineering students UPN "Veteran". Yogyakarta It can be seen from the average score, pre-test results of 27,160, and post-test results of 29,120, the average increased by 1.96. This means that physical strength increases through volleyball. 3) There is a significant difference in influence between volleyball and football, significance at a significance level of 5% of 0.036 and a T-count of -2.152.

Zaman dulu hingga sekarang, bulu tangkis merupakan salah satu olahraga paling populer di Indonesia. Hal ini dapat kita lihat dari banyaknya prestasi para pebulu tangkis kita, sehingga tidak jarang bulu tangkis disebut sebagai aktris unggulan Indonesia yang kerap disandingkan secara internasional dengan mengharumkan nama negara. Penelitian ini memuat masalah tentang peningkatan teknik servis bulutangkis jika dilakukan dengan metode latihan terus menerus, peningkatan teknik servis bulutangkis jika dilakukan dengan metode latihan interval. Sebelumnya penulis telah melakukan penelitian di Club PB Taruna, Bletuk, Sidorejo, Godean, Sleman Yogyakarta. Penelitian yang dilakukan dengan metode eksperimen pada seluruh populasi yang ada di PB Taruna dengan jumlah atlet 32 dan semuanya dijadikan sampel, maka penelitian ini menggunakan penelitian populasi. Kemudian dilakukan analisis data dengan menggunakan ANAVA, sebelum menguji dengan ANAVA dilakukan Uji Normalitas (Uji Lilliefors derajat kesahihannya α = 0,05) dan uji keragamannya atau Homogenitas (Uji Barlet dengan derajat kesahihannya α = 0,05). Penelitian yang di dapatkan adalah bahwa metode latihan terus menerus dan metode interval bisa memberi pengaruh pada peningkatan teknik servis bulutangkis, adapun hasil perhitungan yang didapat adalah lebih besar dari F tabel = 4,20 dengan hasil 6,468122271 maka dapat dinyatakan signifikan pada taraf signifikansi 5 %. Teknik servis bulutangkis dengan metode latihan terus menerus rata- rata nilai yang didapat 26,125 dan teknik servis bulutangkis dengan metode latihan interval rata-rata nilai yang didapat 23,25 jadi ada selisih rata-rata 2,875. Maka dapat disimpulkan bahwa ada perbedaan pengaruh latihan terus menerus dan latihan interval.

In general, the trainer's technical abilities must be mastered by the trainer. The reason is that those who become coaches are generally former athletes. They are also have training certificates from various training and coaching clinics. However, the ability to communicate in coaching is not necessarily fully mastered by most coaches. The purpose of this research was to add theoretical development about the study of sports coaching communication, especially in the process of athlete physical and mental training by using descriptive qualitative research approaches. The results showed that the coaching communication patterns developed in the training process and outside the training. The form of coaching communication during and outside training is generally face-to-face. The method used in coaching communication is to use lectures and demonstrations as well as to involve video media to further stimulate achievement motivation for each athlete. The approach taken in coaching communication is an open, family, and personal approach. The choice of coaching communication methods has been proven to be able to motivate and build athletes' self-confidence and athletes can accept and interpret the instructional messages conveyed and desired by the coaches. Suggestions and recommendations that can be given in this research are on the certification of trainers for each sports trainer.
