Abstract

Ada kepercayaan umum bahwa minuman istonik berpotensi meningkatkan daya tahan dan aldosterone pada saat latihan dan pemulihan.Namun kepercayaan itu perlu dikaji ulang karena masih bisa untuk diperdebatkan dan lebih banyak lagi bukti empiris. Penelitian ini bertujuan untuk menguji minuma isotonik, air dan kontrol pada respon fisiologis, termasuk kapasitas daya tahan dan aldosterone pada saat latihan dan pemulihan pada saat cuaca panas. Dua belas atlet sepakbola prosseional dari Khon Kaen FC, Thailand yang terlibat dalam penelitian ini.  Lari 3000 m, pemulihan 1 jam, dan waktu untuk uji kelelahan dilakukan dalam penelitian ini. Hasil penelitian menunjukkan tidak adanya respon fisiologis selama lari 3000 m dan pada saat pemulihan, denyut jantung lebih rendah dalam uji coba minuman isotonik dibandingkan dengan air dan control. Adanya perbedaan suhu oral, detak jantung, aldosteron, glukosa darah, dan natrium pada saat tes kapasitas daya tahan. Dapat dikatakan bahwa konsumsi minuman isotonik dapat meningkatkan kapasitas daya tahan dan mempertahankan aldosteron lebih efektif daripada dengan atau tanpa air yang mungkin disebabkan oleh peningkatan retensi cairan.

Abstract

The theory of accomplishment-generating motivation only adopts a social cognitive method to research behavior and motivation in sports education settings, illuminating how achievement goal theory is useful for anticipating and explaining beliefs, reactions, and behaviors in achievement settings. This study aimed to investigate how different teaching approaches teacher-centered and student-centered affected the emotional and cognitive motivational responses of students during physical education classes. Using several Mosston and Ashworth teaching methods, including command style, reciprocal style, and guided exploration style, four teachers instructed 92 students. To evaluate teaching style, the Ames coding system was employed. In this inquiry, a strategy of mixed methods was used. By adjusting the work design, authority, recognition, grouping, assessment, and class time structure, the video data was evaluated. The hard disk software enables the recording of audio and video recordings as well as the real-time analysis of information acquired from course observations in physical education. An ANOVA analysis with the Bonferroni correction method was carried out to prevent Type 1 errors, and it produced an alpha level of 0.002 as a result. The command style, reciprocal style, and guided style all performed significantly differently, according to the Tukey test, in terms of total mastery and teaching style effectiveness. According to the findings, guided and reciprocal discovery styles were more effective than command approaches in terms of student mastery, less focused teacher behavior, and cognitive and emotional responses.
