The objective of this research is to find out different impacts of the teaching methods; practice style and command style. This research is conducted in the Faculty of Sports Science, State University of Padang during the academic year of 2010/2011. The applied research method is an experimental method. The sample consists of 40 (college) students who are divided into 4 groups of 10 persons. The data analysis technique is performed by a two-ways variance analysis followed by the tukey test at the significance level = 0, 05. The results of this research are: 1) in all aspects, the skill of butterfly stroke by the teaching method of command style is better than the practice style, 2) for the students with high motor skills, the skill of butterfly stroke by the teaching method of practice style is better than the command style, and 3) for the students with low motor skills, the skill of butterfly stroke by the teaching method of command style is better than the practice style. Keywords: teaching methods of practice style and command style; motoric abilities; the skill of butterfly stroke.

Abstract Introduction. The aim of the study was to ascertain the physiological effects of verbal feedback on changes in the movement efficiency of a dry-land swimming ergometry task (butterfly stroke). Material and methods. The study involved 100 healthy and physically active males (1st year university students majoring in physical education) that were untrained in swimming (19.56 ± 1.32 years of age, 181.23 ± 4.35 cm in height, and 70.54 ± 8.6 kg in weight). The sample was randomised into two groups (control and experimental). In the first trial, both groups executed the butterfly stroke on a Weba Sport swim ergometer with no augmented feedback. In a second trial, the experimental group was provided with verbal cues relating kinesthetic information on task execution. Trial duration was 10 min, with the first 5 min devoted to the swimming task and the remaining 5 min serving as a cool-down. Variables under consideration included physiological cost, rate of recovery, heart rate recovery, estimated recovery time, and work output. Results. No improvement in the variables related to the physiological cost was observed in the verbal feedback condition although a significant increase in work output was observed in the experimental group (p < 0.05). Conclusions. An improvement in work output without modulating the physiological cost of work suggests that appropriately prepared verbal cues may enhance performance in a swimming ergometry task.

The aim of this study is to looking the contribution of flexibility shoulder muscle as well as the muscular power of the hands in relation to the skill of butterfly stroke. The population or research subjects used are students of study Program PJKR FKIP Unsyiah 2015 number of 132 MHS. Sample or data source selected using Purposive Sampling technique with consideration of value for MK TP. Renang Lanjutan Category A is B a number of 25 people. Data collection is carried out using the Flexibility shoulder test and measurement approach, the leg muscle explosive power, and the butterfly swimming ability test. The collected data is processed using the mean statistical approach, deviation standard, regression analysis, as well as test F. Data processing results obtained score rx1y worth 0.91 contribution worth 82.81%, rx2y worth of 0.87 contributed worth 75.69%, and Rx1x2y Worth 0.86 But the value of Fcount is greater than that of Ftabel with significance worth. Abstrak Tujuan dari penelitian yang dilakukan ini adalah untuk mengetahui kontribusi flexibilitas otot bahu serta daya ledak otot tungkai dalam kaitannya dengan keterampilan berenang gaya kupu atau butterfly stroke. Populasi atau subjek penelitian yang digunakan yaitu Mahasiswa Program Studi PJKR FKIP Unsyiah angkatan 2015 sejumlah 132 Mhs. Sampel atau sumber data dipilih dengan menggunakan teknik Purposive Sampling dengan pertimbagan nilai untuk MK Renang Lanjutan kategori A samapi B sejumlah 25 orang. Pengumpulan data dilakukan menggunakan pendekatan tes dan pengukuran kelentukan bahu, daya ledak otot tungkai, serta tes kemampuan renang gaya kupu. Data yang terkumpul diolah mengunakan pendekatan statistik mean, standar deviasi, analisis regresi, serta uji F. Hasil pengolahan data diperoleh score rx1y senilai 0,91 berkontribusi senilai 82,81%, rx2y senilai 0,87 berkontribusi senilai 75,69%, dan Rx1x2y senilai 0,86 namun nilai Fhitung lebih besar dari pada Ftabel dengan signifikansi senilai 95% (db= n-k-1) yaitu= 25 – 2 – 1 = 22, oleh sebab itu didapati Ftabel=3.54, serta Fhitung=36. Sehubungan dengan itu dapat digambarkan bahwa kelentukan bahu dan daya ledak otot tungkai berkontribusi signifikan terhadap kemampuan renang gaya kupu-kupu. Kata Kunci:  Kelentukan, Power, Gaya Kupu-kupu
