Area of Science:

  • Exercise Physiology
  • Cardiopulmonary Function
  • Sports Medicine

Background:

  • Establishing normative data for cardiopulmonary responses to exercise is crucial for assessing individual fitness and health.
  • Previous studies have focused on Western populations, necessitating region-specific data for accurate interpretation.

Purpose of the Study:

  • To establish reference standards for cardiopulmonary responses during maximal exercise in healthy Chinese subjects residing in Taiwan.
  • To develop predictive equations for key exercise parameters based on anthropometric and demographic factors.

Main Methods:

  • One hundred and five healthy, sedentary subjects (55 men, 50 women, aged 20-75 years) underwent graded cycle ergometer testing to exhaustion.
  • Measurements included expiratory gas volume, oxygen and carbon dioxide concentrations, and heart rate.

  • Parameters like maximal work rate (WRmax), maximal oxygen consumption (VO2max), and oxygen consumption at anaerobic threshold (VO2AT) were determined.

    • Main Results:

    • Predictive equations were derived for WRmax, VO2max, VO2max/BW, HRmax, VEmax, and VO2AT, incorporating age, height, body weight, and gender.
    • High correlation coefficients (R values ranging from 0.61 to 0.90) indicate the reliability of these predictive models.
    • Significant influence of age, anthropometrics, and gender on cardiopulmonary responses was observed.

    Conclusions:

    • The study provides valuable, validated predictive equations for cardiopulmonary exercise responses in the Taiwanese population.
    • These standards can be utilized for clinical assessments, exercise prescription, and research in this demographic.
    • This research contributes essential normative data for exercise physiology in East Asian populations.
