PENGARUH LATIHAN AEROBIK TERHADAP PERUBAHAN VO2 MAX PADA SISWA SEKOLAH SEPAK BOLA TUGU MUDA SEMARANG USIA 12-14 TAHUN

Abstract

Background: Exercise is very important for keeping and increasing healt. Exercise is classified aerobic and anaerobic. Aerobic exercise will affect the cardiorespiratoric more than anaerobic one, because it will enhance the oxygen uptake. Men fitness can be measured by the VO2 max values. VO2 max is the maximum amount of oxygen in millilitres, one can use in one minute per kilogram of body weight. Those who are fit have higher VO2 max values and can exercise more intensely than those who are not as well conditioned. Objectives: To know that how programmed aerobic exercise influence the VO2 max change in 12 weeks. Method: This way an experimental study using pre and post test control group design. Seventy students were divided in two groups, treatment and control groups. Measurement performed before, on 6th weeks and after the 12 weeks treatment period for dtetermination of the VO2 max, both control and group of treatment. Result: There was significant increases of VO2 max in the treatment group after 12 weeks programmed aerobic exercise. There was not significant increases of VO2 max in the control group after 12 weeks anaerobic exercise. There was significant difference of VO2 max values between treatment and control group at 12th week. Conclusion: Aerobic training for about 12 weeks could increase VO2 max values. Key words: aerobic exercise, VO2 max
