ANALYSIS OF CARDIOPULMONARY RESISTANCE UNDER DIFFERENT LOADS IN AEROBIC EXERCISES

Introduction: The key objective of aerobic exercise is enhancing cardiorespiratory endurance. On the national gymnastics plan implementation, the idea of lifelong sports was gradually accepted by the masses, and the aerobic gymnastics concept was sweeping the world. Objective: Analyze the cardiorespiratory endurance responses in female college students under different frequencies in aerobic exercise. Methods: 20 female professors and civilian women were randomly selected and divided into two groups.The experimental group performed 45 and 90 minutes of aerobic exercise to analyze changes in cardiopulmonary function before and after each exercise. Results: After 16 weeks of aerobic exercise with different loads, all young women who had participated in the program training showed a significant increase in vital capacity and maximal oxygen uptake capacity. The vital capacity of the 90-min aerobic exercise group was significantly higher than that of the 45-min aerobic exercise group (P<0.05). Conclusion: The establishment of a cardiorespiratory endurance response model can accurately analyze the effects of different aerobic exercise frequencies on cardiorespiratory endurance.
