Korelasi perubahan nilai VO2max, eritrosit, hemoglobin dan hematokrit setelah latihan high intensity interval training
No full textKebugaran kardiorespirasi memungkinkan aktivitas fisik dalam waktu lama dan memerlukan oksigen untuk mendapatkan energi. Transpor oksigen dimediasi oleh hemoglobin yang terdapat dalam eritrosit. Kebugaran kardiorespirasi dapat diukur berdasarkan nilai VO2max. Metode latihan High Intensity Interval Training (HIIT) terbukti dapat meningkatkan VO2max. Namun belum jelas apakah peningkatan VO2max diiringi dan berhubungan dengan perubahan nilai hemoglobin, eritrosit dan hematokrit. Penelitian ini mempelajari korelasi perubahan nilai VO2max, hemoglobin, eritrosit dan hematokrit sebelum dan sesudah latihan HIIT selama 8 minggu. Berdasarkan hasil penelitian, VO2max meningkat sebesar 7,33±4,03 (ml·kg-1·min-1) atau 20,36% (p\u3c0,05), hemoglobin dan eritrosit meningkat sebesar 0,04±0,63 atau 0,24% (p\u3e0,05) dan 0,02±0,22·106/µL atau 0,32% (p\u3e0,05) sedangkan hematokrit mengalami penurunan sebesar 0,12±2% dari volume darah atau 0,27% (p\u3e0,05) dari nilai pre-test. Uji korelasi menunjukkan ada hubungan (p\u3c0,05) antara perubahan nilai hemoglobin, eritrosit dan hematokrit, namun tidak terdapat hubungan (p\u3e0,05) dengan peningkatan VO2max.
Correlation of Change in VO2Max, Hemoglobin, Erythrocytes, and Hematocrit After High Intensity Interval Training
Abstract
Cardiorespiratory fitness allows physical activity for a long time and requires oxygen to gain energy. Oxygen transport mediated by hemoglobin present in erythrocytes. Cardiorespiratory fitness can be measured based on VO2max values. High Intensity Interval Training (HIIT) have been shown to improve VO2max. It is not clear whether the increase in VO2max is accompanied and associated with changes in hemoglobin, erythrocyte and hematocrit values. This study aim to find out the correlation of VO2max, hemoglobin, erythrocyte and hematocrit changes before and after HIIT for 8 weeks. The results VO2max increased by 7.33±4.03 (ml·kg-1·min-1) or 20.36% (p\u3c0.05), hemoglobin and erythrocytes increased by 0.04±0.63 or 0.24% (p\u3e0.05) and 0.02±0.22·106/μL or 0.32% (p\u3e0.05) whereas the hematocrit decreased by 0.12±2% of blood volume or 0.27% (p\u3e0.05) of the pre-test value. The correlation test showed a correlation (p\u3c0.05) between changes in hemoglobin, erythrocyte and hematocrit values, but no relationship (p\u3e0.05) with increased VO2max

The research and data collection were conducted by applying qualitative approach through observation, interview, documentation on seven State \u27LPTK\u27, education office, teacher profession association, teaching practice student, teaching practice supervising lecturer, headmaster, and teacher tutor. The data analysis in this stage was conducted based on the technique developed by Miles and Huberman. Data validity was tested with data triangulation using double sources as comparison. The product development stage included model pre-design making, introductory test, model revision, model test, model revision, field test, and final model revision. First stage model test was conducted in mechanical engineering department with three vocational schools. The second stage model test was conducted in mechanical engineering department with six vocational schools. The last is dissemination stage in the form of spreading the model yielded from the product development to professionals, authorities, and policy makers. The result at this research is a teaching practice model called KPrIP2 which consists of four main product components. K means partnership between Mechanical Engineering Department of State University of Surabaya and the education office of province/ regency/city in continuous planning, action, and evaluation. Pr means pre-teaching practice in which the students do introductory activities in vocational schools to observe and coordinate with the school\u27s department to determine who will be the teacher tutor and what material/subject to be used in the teaching practice II. I means that all pre-teaching practice activities, starting from classroom peer-teaching, laboratory peer-teaching, microteaching, and real teaching in vocational school, are conducted individually and independently. P2 means that teaching service activities must be supervised by competent/professional advisors, i.e. who have the same pedagogical and major background with the students who do the teaching practice and play role as the supervising lecturer of teaching practice I which is continued to be the advisor in teaching practice II. Teaching practice model KPrIP2 is claimed to be effective to reach the teaching practice objectives but inefficient in budgeting
