This study aims to determine: 1) the effect of physical activity on cardiorespiration, 2) the effect of haemoglobin levels on cardiorespiration, 3) the effect of physical activity and haemoglobin levels on cardio respiration, and 4) the contribution of physical activity and haemoglobin levels to cardiorespiration. The research method used is a survey method. The respondents of this study were 194 students of the Department of Sport Education, Faculty of Sports Science, Yogyakarta State University (FIK UNY) who were taken randomly. The data used are respondents' cardiorespiratory rate, physical activity, and hemoglobin levels, which are measured using instruments such as multi-stage tests, Global Physical Activity Questionnaire (GPAQ), and hemoglobin haemometer. The data analysis technique used a regression test. The results showed that at a significance value of 0.001 < 0.05, there was a significant effect between physical activity and cardiorespiration, haemoglobin levels with cardiorespiration, and physical activity with haemoglobin levels. Physical activity or haemoglobin levels affect cardiac respiration by 83%. This study concluded that cardiorespiration is strongly influenced by physical activity and haemoglobin levels. © 2021 South Ural State University - Institute of Sport, Tourism and Service.
