The purpose of this study is to find an overview of how the learning strategies and barriers for Physical Education, Sports and Health teachers providing fundamental movement material during the Covid 19 pandemic. This research includes quantitative descriptive analysis. This research used survey method with close-ended question as the instrument distributed on google form. Respondents in this study were primary school PJOK teachers, in which about 49 people. Data were analyzed using percentage calculations. The conclusions of this study indicate that fundamental movement learning is carried out online by utilizing various kinds of teaching materials such as books, PowerPoint slides, videos, and handouts. The most widely used media is the WhatsApp group. The learning method used by PJOK teachers is the assignment method. The learning strategies carried out generally give students the task of imitating movements, repeating movements, and recording activities. In general, PJOK teachers do not experience obstacles in conducting online learning.
The main purpose of this study was to compare cycle ergometer training using low intensity and moderate intensity in increasing the catecholamine hormone of overweight females. This study was conducted on 50 overweight females with mean age of 22.44±2.97 years old and body mass index between 25 kg.m.2 to 30 kg.m.2. Treatment was given 4 times per week during 5 weeks periods in Group 1 with low intensity cycle ergometer continuous training (60%-70% HRmax), and Group 2 with moderate intensity cycle ergometer continuous training (70%-80% HRmax). Heart rate was monitored using polar heart rate monitor H10. Pre-test was taken before giving treatment and post-test after giving a treatment by taking blood a day after doing exercise and fasting at night and the blood samples obtained are taken to the laboratory for serum sample analysis. Data were analyzed using paired t-test. The result found that there was an increase in catecholamine hormone in both groups with a p-value of <0.05. It can be concluded that cycle ergometer training using low and moderate-intensity improved catecholamine hormone for overweight females.
Dosen adalah seseorang yang memiliki sebuah kewajiban untuk melakukan penelitian ilmiah. Maka dari itu Roadmap penelitian sangat diperlukan agar para dosen Prodi Sarjana Terapan D4 Kepelatihan Olahraga UNESA dapat memiliki pedoman dalam penelitian guna mendukung pelatih fisik berbasis IPTEK yang sesuai dengan visi dan misi prodi tersebut. Tujuan penelitian ini adalah untuk mengembangkan roadmap penelitian program studi sarjana terapan D4 kepelatihan olahraga. Penelitian ini menggunakan metode deskriptif analisis dengan pendekatan kuantitatif sederhana. Hasil observasi penelitian yang telah dilakukan pada 6 orang dosen Prodi Sarjana Terapan D4 Kepelatihan Olahraga selama 4 tahun terkahir (2018 – 2021) telah melakukan penelitian dengan topik teknologi olahraga hanya sebanyak 1% dan kepelatihan olahraga (kondisi fisik) sebanyak 9%. Dari hasil tersebut kemudian disusun rancangan Roadmap dengan tujuan akhir menciptakan alat digital untuk latihan fisik olahraga pada atlet sesuai cabang olahraga. Kesimpulannya tema riset yang digunakan oleh Program Studi Sarjana Terapan D4 Kepelatihan Olahraga Universitas Negeri Surabaya adalah pengembangan kajian prestasi olahraga dengan topik riset prioritasnya adalah pengembangan dan kajian kondisi fisik, model variasi latihan olahraga dan peralatan yang digunakan, latihan fisik olahraga.
This study aims to analyze the effect of curcumin on serum levels of creatine kinase (CK) and malondialdehyde (MDA) after 24 hours of high-intensity physical exercise. This experimental study used a pre and post-control group design. A total of 18 healthy men with an average age of 23 years participated in this study. Subjects were selected using a random sampling technique and then the subjects were divided into 2 groups, namely the group given a placebo and the group given curcumin at a dose of 400 mg. On the first day, all subjects took data on the characteristics of the research subjects, and then the subjects did the high-intensity physical exercise in the form of squad and leg press exercises with an intensity of 80-90% of maximum ability. On the second day, after 24 hours, all subjects took pre-test data samples to measure serum CK and MDA levels, then the intervention was given based on their respective groups. On the third day, after 24 hours, all subjects took post-test blood samples to measure CK and MDA serum levels. Blood samples were analyzed in the laboratory using the ELISA method. The results of this study reported that the group given a placebo did not significantly reduce serum CK levels, while the group with curcumin at a dose of 400 mg could significantly reduce CK levels (p<0.05). Furthermore, there was no significant decrease in serum MDA levels in the placebo group or the curcumin group (p>0.05). It can be concluded that the administration of curcumin after 24 hours after high-intensity weight training was able to reduce serum CK levels without a decrease in MDA serum levels. Since the decrease in serum CK levels is an essential part of recovery during muscle damage. Therefore, curcumin is recommended to be taken after 24 hours after exercise to speed up recovery. Keywords: Curcumin; creatine kinase; malondialdehyde; muscle damage; free radicals; physical training
The global pandemic caused by the Covid-19 virus reduces human activities in various aspects of life, including sporting events. Restrictions on activities on a large scale make sporting events that have the potential to gather large numbers of people prohibited from being held to prevent the transmission and spread of this virus. In addition to sporting events, preparatory exercises for sporting events must also be carried out independently in their respective homes. The implementation of independent training in the long term with supervision through online media has an influence on athletes in physical, technical, tactical and psychological performance. The purposes of this study are (1) to describe the psychological problems of athletes carrying out independent training programs during the covid-19 pandemic, (2) to explore the causes of psychological problems, (3) to explore the strategies chosen by athletes in overcoming psychological problems. The method used in this research is descriptive qualitative with a case study approach through in-depth closed interviews with sports athletes who run an independent training program during covid 19. Data analysis was carried out using the step of grouping problematic data that occurred and presented in the form of percentages and discussion The results of this study show Independent exercise programs at home have a psychological impact on athletes in the form of anxiety, boredom, stress, and obsession. Suggestions from the results of this study should be exercise in quarantine involving athletes and coaches in one camp equipped with training facilities and a recreational situation.
