Abstract

Consumption of protein in weight training when adjusted to the needs will result in perfect muscle growth and development, especially in increasing maximum strength. In fact, many Fitness Members consume protein without paying attention to the dose, so that increasing maximum strength is not realized properly. This study aims to provide high-protein supplements and high-protein foods in weight training to increase maximum muscle strength. The design used in this study is a three group pre test and post test, consisting of a group consuming high protein supplements, a group consuming a high protein diet and a control group. The population in this study are FIK UNP students, with a total sample of 39 people. The instrument used in this study is a maximum strength test (leg & Hand Dynamo Meter test). The data obtained in this study are analyzed by analysis of variance (ANOVA) with = 0.05. The results showed: (1) There was a difference in effect between the group given high protein supplements, high protein die,t and the control group, (2) The group given high protein supplements had a difference from the average of the other two groups, (3) The group given high protein supplements high-protein supplements had a difference from the average of the other two groups, (4) The high-protein diet group did not have a mean difference with the control group. The limitation in this study is that the researcher was not able to control aspects that were outside the research activities such as other high protein contamination consumed by the research food samples. The next stage, this research will look at the effects of consuming high-protein supplements on a sustainable basis on human health.

Abstract

Digital-based gymnastics learning media is one of the efforts to achieve effective and efficient learning goals, especially in the rolling front round material. Therefore, this study aims to develop digital-based gymnastics learning media on rolling front round material which contains a direct assistance approach and indirect assistance approach. This research is a research and development that aims to produce and test the effectiveness of the product. This research consists of several stages, namely product design, product testing, and product implementation. A total of 45 gymnastics students at the department of sports education, faculty of sports science, Padang State University were used as research samples. 15 of them were used for small group trials, and 30 for large group trials. This research also involves material experts and media experts to validate the products developed. Expert validation results obtained an average of 83.33 or very good (material experts 80.00 and media experts 86.67). Meanwhile, the results of field trials obtained an average of 88.06 or showed a very high level of reliability (small group 88.90 and large group 87.23). In conclusion, this developed media can be used as a tool in learning gymnastics, whether it is used for physical education teachers, students, and athletes to improve round front rolling skills. Future research is needed to involve other materials in gymnastics learning with an attractive design and appearance, as well as a wider sample size.
