Penelitian ini bertujuan untuk mengevaluasi pengaruh latihan plyometric terhadap kemampuan power (kekuatan dan kecepatan) tim futsal MTS Al-Islam Joresan Ponorogo. Metode penelitian yang digunakan adalah eksperimental dengan desain pre-test dan post-test control group. Subjek penelitian terdiri dari dua kelompok, yaitu kelompok eksperimen yang menjalani latihan plyometric dan kelompok kontrol yang tidak menjalani latihan tersebut. Pengambilan data dilakukan melalui tes power yang mencakup aspek kekuatan dan kecepatan dalam konteks permainan futsal. Data dianalisis menggunakan uji t dan uji perbedaan rata-rata. Hasil penelitian menunjukkan bahwa terdapat peningkatan yang signifikan dalam kemampuan power tim futsal MTS Al-Islam Joresan Ponorogo setelah menjalani latihan plyometric. Kelompok eksperimen menunjukkan peningkatan yang lebih besar dibandingkan dengan kelompok kontrol. Hal ini menunjukkan bahwa latihan plyometric memiliki pengaruh positif terhadap power dalam permainan futsal, mencakup peningkatan dalam kekuatan dan kecepatan. Implikasi dari penelitian ini adalah pentingnya memasukkan latihan plyometric dalam program latihan tim futsal untuk meningkatkan kinerja dalam kompetisi, terutama dalam hal kekuatan dan kecepatan.

EFFECT OF LOW-COST EMG FOR LEARNING MUSCLE CONTRACTIONS IN SPORT COLLEGE STUDENTS

Surface electromyography (SEMG) is an application that helps coaches and athletes recognize and understand muscle contractions during practice and matches. Unfortunately, this tool is very expensive, so it is necessary to develop SEMG, which is cheap but has the potential to detect muscle contractions during movement. This research aims to develop an inexpensive SEMG for detecting muscle contractions. 10 sports students participated in this study, and they were active in carrying out measured and programmed physical activities four times a week. This research is an experimental study; all students will do barbell squats at 80% of the maximum load. Differences in muscle contractions on the SEMG sensor during concentric and eccentric contractions will be analyzed using the paired sample t-test. The results of this study found a difference in the amplitude of the two muscle contractions with p <0.05; besides that, for the first test, this tool was successful in describing a picture of the amplitude that continues to decrease in muscle contractions in fatigued conditions, although there needs to be an additional indicator in assessing the condition tired for SEMG. This study concludes that the SEMG sensor can detect muscle contractions due to a sports movement. Initial experiments in this study successfully detected muscle contraction signals due to different movements used low cost SEMG; then, it needs to be developed better to reduce noise due to electronic devices' influence around SEMG.

TINGKAT AKTIVITAS FISIK DAN STATUS GIZI SISWA SEKOLAH DASAR DI KOTA SURABAYA PASCA PTM 100% PANDEMI COVID-19

Covid-19 pandemic had an effect on students tegarding changes in sedentary lifestyle during studying at home, coupled with advances in technology which has caused student to prefer games that less phsycal activity, this is feared to still be a habit for students, after covid-19 pandemic. Studying at school that has been proclaimed by Surabaya government, causing a decrease an increased risk of obesity in student. Therefore this study aims to provide an overview the physical activity level and nutritional status of elementary school in Surabaya. this study were examining nutritional status through Body Mass Index and physical activity level using (IPAQ) for student in three elementary schools in Surabaya. the average nutritional status of student based on BMI/age is 19,5±4,02, 1,02% severely thinnes, 21,94% thinnes 56,63% normal, 16,83% overweight and 3,57% obese, the average level of physical activity is 1037±851 MET-min/week, 46,42% low, 40,81% moderate, 12,75% high. This shows that elementary school student in Surabaya have good nutritional status but have a level activity that tends to be less.

The role of psychology in sports is very much needed in achievement sports, especially archery, where many athletes often experience psychological problems during championships or during training sessions. The purpose of this study is to discuss the knowledge structure or factors that influence decisions/actions in archery athletes, using the context review analysis method cited from relevant research results. Reviews in this study examine the results of pre-existing research cited from international journals such as PubMed, Springer, ScienceDirect and Journals from various universities in Indonesia. The results of this study found that there are several factors that can indeed be studied and can influence decisions/actions in archery athletes that can be used and added to team/club training programs to overcome psychological problems experienced by athletes. In conclusion, there are six main factors that influence the decision/action of athletes. It is hoped that these main factors can be applied to athlete training programs as support for performance when practicing or during competition.

PERSEPSI DAN PENGETAHUAN ATLET ATLETIK PERSATUAN ATLETIK SELURUH INDONESIA (PASI) JAWA TIMUR TENTANG PENANGANAN CEDERA

Incidents of injuries that were experienced by track and field athletes in training and matches that are not handled properly. As a result, injury recovery is not always ideal, putting athletes at risk for more serious injuries. This study aims to evaluate the types and treatment of injuries that occur in athletes from the Indonesian Athletics Association (PASI) in East Java Province. This research was conducted in cross-sectional with descriptive and comparative data analysis methods. There were 141 athletic athletes aged 17.97 ± 2.314 years participated in this study. Different test analysis was carried out based on gender, age, and number of competitions that were followed. The instrument used is a questionnaire whose statement items have been tested for validity using Pearson Product Moment and show valid results (p-value <0.05). The results of the normality test showed that the data did not have a normal distribution (p-value <0.05). The non-parametric test showed no significant differences in the perception of injury management based on gender, age, and match number (p-value > 0.05). Furthermore, on the athlete's knowledge, the majority of athletes still believe in traditional handling and do not know first aid for injuries using the Rest, Ice, Compression and Elevation (RICE) method.
