Key result
Ninety-minute aerobic exercise increases vital capacity more than 45-minute sessions in young women.
Why the study?
The study was conducted to analyze cardiorespiratory endurance responses under different frequencies of aerobic exercise.
Does 90 minutes of aerobic exercise improve cardiorespiratory endurance more than 45 minutes in young women?
RCT (n=20)
randomly selected and divided into two groups
No
Does 90 minutes of aerobic exercise improve cardiorespiratory endurance more than 45 minutes in young women?
Absolute Event Rate: 3183.6% vs 3149.2%
p-value: p=<0.05
Longer duration (90 min) of aerobic exercise yields greater improvements in vital capacity compared to shorter duration (45 min) in young women.
Longer aerobic sessions may optimize vital capacity gains in young women; extends limited RCT evidence on exercise duration for cardiorespiratory outcomes.
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. Evidence Level II; Therapeutic Studies – Investigating the results.

Li et al. (2022) reported an RCT. 90 minutes of aerobic exercise vs. 45 minutes of aerobic exercise was evaluated on Vital capacity (VC) (p=<0.05). 90 minutes of aerobic exercise significantly increased vital capacity compared to 45 minutes of aerobic exercise in young women after 16 weeks (P<0.05).
