Abstract

This study aims to determine whether the competences of Physical Education (PE) teachers make contributions to the quality of learning achievements of elementary school students. It was qualitative descriptive research using a reflective explorative approach. The subject of this study was the result of competence test of PE teachers in Yogyakarta Special Region in 2016. The study involved 60 PE teachers who were subjected to have an FGD (Forum Group Discussion) in some stages. The results show that the average score obtained by elementary school PE teachers in their Teacher Competence Test (TCT) stage II in 2016 was 61.79 for the pedagogical competences, and 60.07 for the professional competences. These results could exceed the national average score of 53.7. Based on the interviews with several teachers, the results of the competence tests had not indicated that PE elementary school teachers could improve the students’ learning quality. The teachers focused more on their preparations to take the TCT as a part of the assignments to the Learning Teacher program they participated in. This study also reveals that the TCT scores did not make a significant contribution to the students’ learning achievements in PE subject. Furthermore, TCT was considered by the teachers as a goal and not as an instrument to improve their competences in the teaching and learning processes.

Abstract

Kalsium merupakan mineral utama yang sangat dibutuhkan oleh atlet untuk kekuatan tulang, sendi dan kontraksi otot pada saat berolahraga. Olahraga berat dan berlangsung lama secara progresif akan meningkatkan kebutuhan kalsium. Inadekuat asupan kalsium berdampak terhadap hipokalsemia yang akan meningkatkan risiko terjadinya cedera olahraga. Tujuan penelitian adalah menganalisis pengaruh suplementasi kalsium terhadap kebugaran dan kesehatan pada atlet Tarung Derajat. Design penelitiannya adalah eksperimental (one group pretest-post test design). Total 21 atlet Tarung Derajat, usia 18-25 tahun, putra dan putri sebagai subjek. Pemeriksaan meliputi, pengukuran: komponen fisik untuk mengetahui kebugaran, anthropometri (berat, tinggi, dan indeks massa tubuh), dan tekanan darah untuk mengetahui profil kesehatan, dan kalsium darah. Intervensi berupa pemberian tablet kalsium sitrat, dosis 1x1000 mg/hari, diberikan setelah makan malam dan selama 35 hari. Hasil penelitian menunjukkan bahwa jumlah atlet putri dengan hipokalsemia menurun 50%, dari 44.44% (sebelum) menjadi 22,22% setelah pemberian kalsium. Kebugaran meningkat (p0,05), namun tidak terjadi perubahan pada berat (p0,05), indeks massa tubuh (IMT) (p0,05), tekanan darah (TD) (p0,05) dan kadar kalsium (p0,05) setelah suplementasi kalsium. Simpulan: suplementasi kalsium menurunkan jumlah hipokalsemia pada atlet putri, meningkatkan kebugaran, dan meningkatkan secara tidak bermakna kadar kalsium. Sebaliknya suplementasi kalsium tidak berpengaruh terhadap anthropometri (berat dan indeks massa tubuh), dan TD pada atlet Tarung Derajat. Effects of calcium supplementation on physical fitness and health profile in tarung derajat athletes AbstractCalcium is the main mineral that is needed by athletes for bone strength, joint, and muscle contraction during exercise. Strenuous and prolonged exercise will progressively increase calcium requirements. This inadequate calcium intake is having an impact on hypocalcemia and increasing the risk of sports injuries. The purpose of the study was to analyze the effect of calcium supplementation on fitness and health in Tarung Derajat athletes. The research design was experimental (pretest-posttest without control group design). A total of 21 Tarung Derajat athletes, aged 18-25 years, male and female were the subjects. The examination was physical fitness, anthropometric values, and blood pressure to determine the health profile, and blood calcium. The intervention was a calcium tablet, a dose of 1x1000 mg/day, given after dinner, and for 35 days. The results showed that the number of female athletes with hypocalcemia decreased by 50%, from 44.44% (before) to 22.22% after calcium therapy. Physical fitness increased (p0.05), but there was no change in weight (p0.05), body mass index (BMI) (p0.05), blood pressure (BP) (p0.05)) and calcium levels (p0.05) after calcium supplementation. Conclusions: Calcium supplementation has reduced the amount of hypocalcemia in female athletes, increased physical fitness, and did not significantly increase calcium levels. Calcium supplementation has no effect on anthropometry (weight and body mass index) and BP in Tarung Derajat athletes.

Abstract

Weight Training adalah metode latihan untuk meningkatkan kekuatan dan kinerja neuromuskular melalui proses hyperthropy, namun juga meningkatkan produksi Laktat, menyebabkan inflamasi otot, meng-gangu metabolisme tubuh sehingga menurunkan performa. Stimulus dingin pada Cold water Immersion dapat mengurangi laju metabolisme, menyerap suhu jaringan lokal, menurunkan kepekaan saraf dan mengu-rangi rasa nyeri sehingga menurunkan resiko terjadinya cidera musculoskeletal dan kelainan metabolisme. Penelitian ini bertujuan untuk menguji pengaruh cold water Immersion 5°C (CWI5°C) terhadap Laktat pada darah, nyeri otot, fleksibilitas dan tingkat stress pasca latihan berbeban intensitas sub maksimal. Pre- dan Post-test dalam penelitian ini menggunakan kelompok kontrol dengan pendekatan cross sectional. Sebanyak 15 sampel kelompok eksperimen diberikan CWI5°C selama 15 menit setelah latihan berbeban, sedangkan 15 sampel kelompok kontrol menggunakan metode Statis Stretching (SS) salama 15 menit. Uji prasarat menggunakan Shapiro-Wilk, sedangkan analisa Bivariate menggunakan Paired Sample T-test dan Independent Sample t-test. Hasil yang diperoleh yaitu metode CWI5°C lebih cepat menurunkan Kadar Laktat (t=2.32±0.27, p=0,001), mengurangi nyeri otot (t=5.32±1.07, p=0,003) dan menurunkan stress (t=13.02±1.27, p=0,001), sedangkan SS meningkatkan fleksibilitas (t=17.98±2.76, p=0,001). Dapat disimpulkan cold water Immersion suhu 5°C selama 15 menit mempercepat proses recovery, mengurangi inflamasi otot dan menurunkan stress, sedangkan statis stretching meningkatkan fleksibilitas setelah latihan berbeban intensitas sub maksimal. The effect of cold water immersion on lactate, muscle soreness, flexibility and stress level post-sub-maximal physical exercises AbstractStrength is one of the main components of bio-motor affecting the development of other physical components. Strength training improves strength and neuromuscular coordination, muscle hypertrophy, contrary causes physical stressor, muscle inflammation, produce muscular disease, increases lactate levels, interferes body metabolism, thus decreases performance. Appropriate recovery methods can prevent over-training, musculoskeletal injuries, stress levels. The study examines the effect of cold water immersion 5°C (CWI5°C) on blood lactate, muscle soreness, flexibility, and stress level after high-intensity resistance training. The study design was pre- and Post-test using a cross-sectional approach with the control group. It gave selected 15 samples treated with CWI5°C for 15 minutes directly after high-intensity resistance training, while control samples with static stretching for 15 minutes. The prerequisite test uses Shapiro-Wilk, while the bivariate analysis uses paired sample T-test and independent sample T-test. The prerequisite test uses Shapiro-Wilk, while the bivariate analysis uses paired sample T-test and independent sample T-test. The results showed there were significant differences between the two groups (p=0.001). The CWI-5 C method recover lactate levels faster (p = 0.001), reduces muscle pain (p=0.003), decrease stress (p=0.002), while SS increase muscle flexibility (p=0.001). We can conclude that 15°C cold water immersion for 15 minutes accelerates recovery, reduce muscle inflammation and stress level, while static stretching increases flexibility after high-intensity resistance training.
