Factors affecting estimation of the maximum aerobic capacity by treadmill test in students of medical emergencies in Qazvin

Background: The maximum aerobic capacity (VO2max) can be used to evaluate the cardio-pulmonary condition and to provide physiological balance between a person and his job. Objectives: The aim of this study was to estimate the maximum aerobic capacity and its associated factors among students of medical emergencies in Qazvin. Methods: This cross-sectional study was conducted in 36 male students of medical emergencies in Qazvin University of Medical Sciences, 2015. The Physical Activity Readiness Questionnaire (PAR-Q) and demographic questionnaire were completed by the participants. The participants meeting the inclusion criteria were assessed using the Gerkin treadmill protocol. Data were analyzed using Mann-Whitney U test and Kruskal-Wallis. Findings: Mean maximum aerobic capacity was 1.94±0.27 L/min. The maximum aerobic capacity was associated with weight and height groups. There was significant positive correlation between maximal aerobic capacity and height, weight and body mass index. Conclusion: The Gerkin treadmill test is useful for estimation of the maximum aerobic capacity and the maximum working ability in students of medical emergencies
