RELATIONSHIP OF HEMOGLOBIN CONCENTRATION AND LUNG VITAL CAPACITY WITH MAXIMAL AEROBIC CAPACITY (VO2 MAX) AT INDONESIAN NATIONAL ATHLETES

Abstract

The objectives of this research are to obtain information the relationship of hemoglobin concentration and lung vital capacity with VO₂ max at Indonesian national athletes either separately or together. This study was conducted at Indonesian national athletes by using survey method with regression and correlation techniques analysis. The number of 50 athletes  from 550 populations as a sample is selected purposive random sampling, The research findings there are 1). There is a relationship of hemoglobin concentration with VO₂ max, equation of regression ,used T test (α= 0,05), t_value = 10,25,  t_table = 2,00, correlation coefficient ; rxy₁=0,719 and determinant coefficient (r²) = 0,517, 2). There is a relationship of lung vital capacity with VO₂ max, equation of regression , used T test (α= 0,05), t_value = 7,48, t_table = 2,00, correlation coefficient; rxy₂=0,733  and determinant coefficient (r²) = 0,538 , 3).  There are a relationship of hemoglobin concentration and lung vital capacity are together with VO₂ max, equation of regression , used T test (α= 0,05), t_value = 87,28,  t_table =1,59, correlation coefficient ry_1-2 = 0,734 and determinant coefficient(ry_1-2) = 0,539
