Effect of Treadmill Exercises on Vo2 Max, Haemoglobin Levels and Erythrocyte Index among Military Candidates

摘要

Sports or physical activities most in demand, especially in urban areas, are sports or treadmills. The benefits of a treadmill include increasing muscle strength, improving metabolism, increasing oxygen absorption in the blood, and training the heart and lung muscles. The purpose of this study was to determine the effectiveness of treadmills to increase $VO_{2} Max$, haemoglobin levels, and erythrocyte index in Medan City non-commissioned officer (NCO) candidates. The population was the non-commissioned officers who trained treadmills at Army Fitness as many as 50 people and sample is limited to 15 people who meet the inclusion requirements. The type of research is quasi-experimental through pre-test and post-test. The technique of analysing data used the SPSS version 22.0 and the test used the Wilcoxon Signed Ranks Test. The results showed that exercise was a treadmill effective in increasing VO2Max for non-commissioned officers in Medan City; workouts are treadmill not effective against Haemoglobin levels in non-commissioned officers in Medan City and training treadmill effective against the Erythrocyte Index for Mean Corpuscular Volume (MCV). The research results conclude that exercise is treadmill only effective in increasing VO2Max and MCV index values in erythrocytes.
