Body height impact on cardiorespiratory fitness among physically active adult

Background: Physical exercise is the major key to aerobic or cardiorespiratory fitness for all ages. It is affected by body composition, body mass index and physical stature. Objective: the objectives of the study was to compare cardiorespiratory fitness (CRF) among stature categories of height (SCH) i.e., tall, above medium, medium and low height of physically active adult males and to find an association between height and cardiorespiratory fitness of the subjects. Methods: 84 male physically active subjects, age 21-26 years were randomly included in this study. Body height was measured by stadiometer and Copper 12 minutes run and walk test was conducted to test CRF. Subjects were categorised into four groups as per their height: tall 170-179.9 cm, above medium 167-169.99 cm, medium 164-166.99 cm and low150-163 cm. ANOVA statistical and Pearson correlation were used to test the hypothesis. Result: The sampled subjects were: 26.19% were tall their average height and CRF was 172.14 ± 1.34 and 2518.64 ± 154.20, 20.24 % was above medium their average height and CRF was 167.84 ± 0.70 and 2677.47 ± 216.47, 32.14 % was medium average height was 165.29 ± 0.82 and CRF was 2446.29 ± 251.27 and 21.43 % was low their average height and CRF was of 160.88 ± 2.01and 2379.59 ± 245.81. The study shows relationship between tall height and CRF of r=0.13 p=0.55, between above medium height and CRF r=0.00p= 0.99, between medium height and CRF r=0.34 p=0.86 and between low height and CRF 0.21 p=0.39. All p values are not significant (p<0.05). Conclusion: CRF among SCH showed a significant difference, above medium categories CRF was significant better then medium and low categories of height. Study found no significant relation between CRF and SCH.
